AI personal knowledge management

Give every thoughtthe shape of knowledge

Capturing is easy — the hard part is still finding it three months later. Sorp grows the voice notes, text and photos you drop in into a chaptered body of knowledge. You never build a folder tree, and you never maintain one. Want a new capability? Describe it in one sentence and let the AI build it.

Coming soon to the App Store Why it does not rot

4 ways: in: voice · text · photo · scan
0: folders you have to maintain
15: official capabilities, ready to insert

Capture it, and let the AI take it from there

The problem

Every note app you abandoned died of the same thing

It is not a discipline problem. Maintaining structure is simply not work a person should be doing.

Capturing is easy

A voice note, some text, a photo — saved in seconds. This step never failed you.

Finding is hard

Three months later you want that judgement you made. You search everything and only remember that you "said something about it".

Maintaining is impossible

Filing, naming, splitting pages, tagging, linking. Skip it for one day and the backlog never clears again.

Sorp's answer is to take that work away entirely. The AI maintains the knowledge base; you just capture.

How it works

A knowledge base you never maintain, but fully control

"Fully automatic" and "under my control" normally contradict each other. Sorp holds both through four things.

Read-only: structure is not your job

The AI maintains the knowledge base exclusively. Chapters, sections and links are all generated — you never face an empty folder.

Block-level provenance: every line goes back

Every conclusion links to the fragment it came from and the write that created it. Not "the AI said so", but "this is what you said".

One-tap revert: mistakes roll back

Every write leaves a before-and-after snapshot. Read the card, and if you disagree, undo it — the knowledge base returns to the previous state.

Four gates: rather nothing than something wrong

Any automatic write must clear four gates: source allowlist, module allowlist, verbatim quote check, and an independent entailment check. If the last one fails, the write is discarded.

Authorship discipline

Third-party material never masquerades as your knowledge

Content from news, articles and AI artifacts is never silently written into your knowledge base. It persists only if you approve it yourself.

Because a verbatim-accurate quotation can pass every factual check and still read, to you, like your own belief. That is a misattribution of authorship — harder to spot than a factual error, and harder to undo.

The one write channel

Want it changed? Tell the domain Agent

The domain Agent is your only write channel into the knowledge base. Say "add that pricing judgement from last time" and it does — returning a card you can undo. Plugins have no write access at all: they only read the domain.

Update a knowledge entry
Rewrite a whole domain for consistency
Record a cognition, decision rule or factual claim
Add a term
Write domain memory
Search across the base before answering

Every write comes back as a card, revertible one by one.

Six modules

Only six things to keep track of

Home, Library, Domains, Plugins, Viewpoints, News — everything else is what they produce in the background.

Home

Hold to talk, type, shoot, or scan. Four ways in — and no demand that you organize anything on the spot.

Library

Everything that arrives from outside lands here: imported files, articles, AI-generated artifacts — cross-filtered by origin and type.

Domains

Create a domain for something you care about long-term. The AI interviews you first, then grows scattered notes into a chaptered body of knowledge.

Plugins

Describe the capability you want in one sentence; the AI asks a few questions and builds you a plugin. Or just subscribe to someone else's.

Viewpoints

Hand a question to one thinker, or seat several at a table to debate, with a neutral host summing up agreement and disagreement.

News

Long-form reading recommended by your domains — with an AI close-reading before you commit the time.

The domain Agent lives inside Domains, ready whenever you need it — and plugins only run inside a domain conversation.

Domains · the most unusual part

It interviews you first, then grows the structure

A domain is a container for something you care about long-term — a job, a hobby, a relationship. It is not a folder; it is a structure that grows.

The AI interviews you

One round of questions establishes what you want to study, what you already know, and where the edges are.

A chapter structure grows

From those answers the AI builds a chaptered skeleton — not an empty directory handed to you.

Records file themselves

What you capture afterwards gets judged for relevance and integrated into the right chapter.

Inspiration cards, daily

Up to 5 cards per domain per day, each asking whether a record belongs in the knowledge base.

Cognition ≠ knowledge

Two axes, because their standards of truth differ

"Cognition" records how you think — it has no right answer, only whether it is true to you. "Knowledge" records what you know — it has right answers and needs evidence.

Cognition system

Values, worldview, decision patterns, emotional patterns. No right answer.

Knowledge system

Entries, terms, factual claims. Right answers, fully traceable.

Growth

14 achievement groups, named after the classics

Breaking Ground, Unrolling, Six Harmonies, Word Hoard, Ploughing, Discernment, Prism, Thesis, Strategy, Growth Rings, Persistence, Spark, Hearing the Way, Inquiry.

Plugins

Build yourself a capability in one sentence

A plugin is a capability package: it holds several capabilities, and each capability is one shortcut command. Five ship with the app — and you can build your own by talking.

Built by conversation, no forms

Describe in one sentence what you want the AI to do. It asks a few questions and drafts a plugin; hold to talk and it revises. No form to fill in at any point.

One capability = one shortcut

"Break it down" is /breakdown, "Monthly review" is /monthly. Say the trigger inside a domain conversation to call that capability directly.

Only runs in a domain — and read-only

Plugins run solely inside a domain's Agent conversation, using the domain as their base — but they hold no write tools at all and can never change your content.

Built in: 5 plugins, 15 capabilities

Insertable into any domain, and you can subscribe to other people's from the market.

Think It Through

Take one idea apart

Take an idea apart: break it to first principles, trace consequences of consequences, invert it, run a pre-mortem.

First Principles/拆解Reply
"Help me break this down" → separate verified facts from assumptions, then re-derive the conclusion from the facts alone.
Second-Order/二阶Reply
"What happens if I do this?" → trace first-, second- and third-order effects, and flag the costliest overlooked one.
Inversion/逆向Reply
"Invert it — how would I guarantee failure?" → ask the goal backwards and name what to stop doing right now.
Pre-mortem/验尸Reply
"Run a pre-mortem" → write the failure post-mortem in past tense, then work back to warnings you can act on now.

Retrospective

Turn an experience into a record

Turn an experience into something you can revisit: monthly review, emotion review, decision memo.

Monthly Review/月报Article
"Review my month" → group by theme, keep the key judgements and the single thing to verify next month.
Emotion Review/情绪Article
"I lost my temper again" → separate facts from thoughts and find the earliest signal to catch next time.
Decision Memo/决策Article
"I have decided to…" → write a record for your future self, including the conditions under which you were wrong.

Self-Awareness

See your automatic reactions

See your own automatic reactions: name automatic thoughts, speak fairly to yourself, surface the values behind a hard choice.

Automatic Thoughts/CBTReply
"I am spiralling again" → map the situation → automatic thought → emotion chain, pointing at the distortion with questions rather than verdicts.
Self-Compassion/关怀Reply
"Am I useless?" → help you say something fair to yourself, the way your best friend would.
Values Clarification/价值Reply
"I cannot choose" → name the pair of values actually in conflict, and ask one question that separates their priority.

Write Something

Turn material into something publishable

Turn raw material into something you can publish: social copy, travel journal, food notes — all three come with an image.

Social Copy/文案ArticleImage generation
"Write me a social post" → one specific detail in the first line, one topic only, no slogans.
Travel Journal/游记ArticleImage generation
"Write up this trip" → open on a concrete moment, replace judgement with detail, close on an image.
Food Notes/美食ArticleImage generation
"Note this meal down" → capture the moment it hit your tongue, and why it was worth recording.

Public Digest

Read the news down to a few lines

Read public reporting down to a few lines: today's brief, and recent movement on a topic. Both look things up online automatically.

Today's Brief/要闻ReplyWeb search
"What happened today?" → pick 3–5 items genuinely worth knowing, two sentences each, with sources.
Topic Trends/动态ReplyWeb search
"What is happening with X?" → conclusions first, grouped by thread, with disagreements and unknowns marked.

Plugin market

Subscribe to what others have built

The market shows the author, capability count and how often each plugin has been used, sortable by hot or newest. Once subscribed, you can insert it into your domains. Running someone else's plugin needs an active membership; your own plugins are exempt.

21 thinkers, each with a written blind-spot notice

Hand your question to one thinker, or seat several at a table to debate. Every viewpoint states its own limits — knowing where you will be wrong beats pretending you will not be.

Let us be clear about what this is

These are AI simulations of how historical figures thought, built from public sources. They are for provoking thought. They are not the figures' own words, and no quotations are fabricated. Each figure ships with a blind-spot list defined in our source code — what they would object to, and what they overlook.

Single analysisRoundtable · 2–5 thinkers at one table

Business & Investing

5 thinkers

Charlie Munger

Master of mental models

Blind spots of this viewpoint
Underrates fast-iteration internet playbooks and the non-linear breakout of young industries; his conservative temperament can suppress decisions that require risk; limited value on macro and short-term opportunities.

Steve Jobs

Tyrant of minimalism and taste

Blind spots of this viewpoint
His forceful, unilateral style can ignore team consensus; low price sensitivity means advice may exceed an ordinary budget; an elitist lens underrates mass-market differences; his aggressive approach to health is not worth imitating.

Kazuo Inamori

Philosopher of management

Blind spots of this viewpoint
A Japanese collectivist context sits at a distance from individual-centric internet culture; mechanically applied altruism can blunt competitive aggression; limited experience with rapid scaling playbooks.

Peter Drucker

Father of modern management

Blind spots of this viewpoint
Drawn from large organizations, so it fits very early startups and solo operators poorly; a gradualist temperament is in tension with disruptive innovation; highly abstract, so it assumes some management background.

Benjamin Franklin

Archetype of self-made success

Blind spots of this viewpoint
A pre-industrial virtue checklist needs reworking for modern work rhythms; heavy self-discipline suits divergent creative work poorly; pays little attention to emotional and psychological complexity.

Science & Engineering

6 thinkers

Richard Feynman

The physicist who could teach

Blind spots of this viewpoint
An anti-authority stance can underrate the value of organization and process at scale; limited patience for business and politics; "say so when you don't understand" can look hesitant when a decisive call is needed.

Albert Einstein

Imagination over knowledge

Blind spots of this viewpoint
His long resistance to quantum mechanics shows even geniuses get trapped by an old paradigm; an idealist stance has limited applicability in commercial competition; heavy on theory, light on execution.

Marie Curie

Twice a Nobel laureate, alone

Blind spots of this viewpoint
A working style that sacrifices family and health should not be promoted; the lone-hero path needs rework in modern collaborative R&D; no interest in commercialization or reputation management.

Claude Shannon

Father of the information age

Blind spots of this viewpoint
Models irrational human and organizational factors poorly; an engineering-optimization mindset can miss unquantifiable value such as brand and emotion; market and user understanding is not his strength.

Charles Darwin

Author of evolutionary thinking

Blind spots of this viewpoint
Gradualism explains leapfrog technological revolutions poorly; a modest style can lose focus when a forceful decision is needed; social Darwinism is a misuse of his theory — beware mechanical application.

Alan Turing

Father of computing and AI

Blind spots of this viewpoint
A purely logical framework covers emotion and aesthetics poorly; the injustice he suffered is a reminder that talent needs a tolerant environment; too technical to be understood without translation.

Letters & Thought

6 thinkers

Lu Xun

Dissector of the national character

Blind spots of this viewpoint
An excess of critique can make conclusions sound bleak; his era (national crisis) needs translation for modern personal-growth questions; his edge aims straight at human darkness and may unsettle thin-skinned readers.

Socrates

The gadfly of Athens

Blind spots of this viewpoint
Asking without answering is inefficient when a quick decision is needed; the midwife stance is easily read as arguing for its own sake; underrates intuitive and experiential knowledge.

Laozi

Sage of the natural way

Blind spots of this viewpoint
Highly condensed wisdom must be translated into action by the reader; "not contending" can be misread as passivity in zero-sum settings; mystical phrasing is unfriendly to modern readers seeking certainty.

Wang Yangming

Master of unity of knowing and acting

Blind spots of this viewpoint
Emphasis on inner conscience can turn into self-righteousness for the untrained; success depends heavily on personal cultivation and does not scale; comparatively thin on institutions and systems.

Zeng Guofan

Exemplar of patient self-cultivation

Blind spots of this viewpoint
Extreme self-discipline has a high bar for ordinary people; a hierarchical, obedience-heavy view of organization is distant from flat modern teams; the patient approach can miss windows in fast-iterating industries.

Sima Qian

Historian who judged by history

Blind spots of this viewpoint
Historical analogy can mask fundamental differences in present variables such as technology and institutions; deferred judgment does not suit situations needing immediate feedback; a tragic temperament yields overly heavy advice.

Strategy & Beyond

4 thinkers

Sun Tzu

Strategist of winning without fighting

Blind spots of this viewpoint
A military-confrontation frame can over-competitivize win-win settings; the stratagem flavor needs reconciling with modern business ethics; says less about long-term trust and cooperation than about confrontation.

Leonardo da Vinci

The ultimate curious generalist

Blind spots of this viewpoint
Interests scattered so widely that much was left unfinished — focus and closure are his weak points; genius-level omnicompetence is not reproducible for ordinary people; little interest in systematic, scaled engineering.

Bruce Lee

Cross-domain martial artist, like water

Blind spots of this viewpoint
Intensely individualist expression fits team collaboration poorly; "no form as form" can leave beginners with no structure at all; a short life left his system of thought incomplete.

Aristotle

Founder of the Western tradition

Blind spots of this viewpoint
A static taxonomic framework dates quickly in fast-evolving fields; era-bound views such as those on slavery must be inherited critically; academic rigor can look short on frontline sharpness.

Roundtable

Should I quit and start a company?

Charlie Munger
First work out whether you can survive the worst outcome. Do not stare only at the probability of success.
Steve Jobs
If the product does not excite you, do not start.
Sun Tzu
First make yourself invincible, then wait for the enemy's opening. Consider defeat before victory.

Host summary

Agreement: Sort out the risk and your floor before you move.
Disagreement: Wait for the moment to ripen, or break through on passion.
Suggested action: Run a three-month minimum-cost validation before deciding to commit fully.

FAQ

What you might be wondering

How is this different from flomo, Notion or Obsidian?

All three expect you to build the structure and maintain the taxonomy. Sorp's knowledge base is maintained solely by the AI and is read-only: you only record, while structure, filing and linking are done for you. If you enjoy hand-building a second brain, Sorp is not for you. If you are tired of maintaining it, Sorp is.

What is a plugin?

A plugin is a capability package: it holds several capabilities, and each capability is one shortcut command. It replaced the earlier set of hard-coded templates — now you can build your own. Describe what you want in one sentence and the AI will draft one after a few questions, or subscribe to someone else's. Five official plugins ship with the app (Think It Through, Retrospective, Self-Awareness, Write Something, Public Digest) with 15 capabilities between them, insertable into any domain.

Can a plugin damage my knowledge base?

No — this is an architectural constraint. Plugins only run inside a domain's Agent conversation and treat the domain as read-only: they hold no write tools and cannot change your content. Whichever domain a plugin is inserted into becomes its source material; with no domain, it uses only what you say plus public material.

What if the AI files something wrong? Can I fix it?

Yes. The knowledge base is not sealed: the domain Agent is its write channel, and every write produces a card with a before-and-after snapshot you can revert individually. You can also just tell the AI what to change. Plugins have no write access at all.

Could third-party content end up presented as my own knowledge?

No — this rule is hard-coded. Content from news, articles and AI artifacts is never silently written into your knowledge base; it only persists if you explicitly confirm it. The reason: a verbatim-accurate quotation can pass every factual check yet read as your own belief — that is a misattribution of authorship.

Where is my data stored?

On Alibaba Cloud (object storage and database). Speech-to-text and image understanding are provided by Alibaba Cloud Bailian, the large model by DeepSeek, and one-tap phone login by Alibaba Cloud PNVS. In settings you can inspect and clear the knowledge base, clear local cache, sign out, or unbind WeChat.

How are credits spent? Will I run out?

Capturing notes is free and costs no credits. Credits go to AI generation, priced by actual usage — the same task costs more or less depending on length, rather than a fixed price list. Failed AI tasks are automatically refunded. Running someone else's plugin requires an active membership (your own plugins are exempt).
