自进化知识库 · 你的私人第二大脑 | Self-Evolving Second Brain
它能为你做什么
把散落在电脑里的 PDF，长成一座越用越懂你的私人知识库。
- 📥 自动吞噬：文献丢进一个文件夹，自动读、蒸馏成结构化知识卡，记账去重——读过的绝不重复读。
- 🕸️ 越攒越聪明：卡片自动织成主题网络，知识成为可检索、可追溯的图谱。
- 🎯 越用越像你：持续学习你的语言与判断，产出带你的调性，而不是千篇一律的 AI 腔。
- 🔍 不会瞎编：每个结论都指回具体某张卡或原文，查不到宁可留白——适合严肃写作与研究。
- 💰 帮你省钱：批量处理草稿走便宜模型、终审才用强模型，token 花在刀刃上。
适合谁
研究者与研究生 · 播客 / 写作者 / 深度内容创作者 · 需要长期知识管理又想保持个人风格的知识工作者。
怎么用（三步）
- 把 PDF 放进你的监控文件夹；
- 对它说"吞噬 / 更新知识库"，它自动蒸馏、织网、更新画像；
- 让它"基于知识库写 / 答"，产出有据可查、带你调性的内容。
开始前准备
一个放文献的文件夹即可。全程在你自己的模型环境里跑，数据不出本地、不发送给任何第三方服务。
Turn the PDFs scattered across your computer into a personal knowledge base that understands you better the more you use it.
What it does for you
📥 Auto-ingest: Drop papers into a folder; it reads and distills them into structured knowledge cards, with a ledger that prevents re-reading anything already processed.
🕸️ Smarter as it grows: Cards auto-link into a topic network — not a pile of isolated files, but a searchable, traceable knowledge graph.
🎯 Increasingly you: It continuously learns your language, taste, and judgment, so output carries your voice instead of generic AI tone.
🔍 No hallucinations: Every claim must point back to a specific card or source; if it can't, it leaves a blank rather than making things up — ideal for serious writing and research.
💰 Cost-efficient: In batch mode, drafts run on a cheap model and only final review uses a strong one — tokens spent where they matter.
Who it's for
Researchers & grad students (long-term literature management) · Podcasters, writers & serious content creators (turn what you read into your own asset) · Any knowledge worker who wants long-term knowledge management while keeping a personal voice.
How to use it (3 steps)
Put PDFs into your watched folder;
Tell it to "ingest / update the knowledge base" — it distills, links, and updates your profile automatically;
Ask it to "write / answer from the knowledge base" for output that's source-grounded and in your style.
Before you start
Just a folder for your papers.
Everything runs in your own model environment; no data leaves your machine or goes to any third party.
