LLM Knowledge Base · MCP Native · Cross-platform · EN & 中文

The LLM Knowledge Base your AI can read and write.

Not another note app. A protocol-native knowledge base where Claude, ChatGPT, Cursor, and any MCP client can save, search, and grow your long-term knowledge — in the middle of a conversation.

Voice works too — record a note, AI transcribes, extracts insights, and saves to your knowledge base.Your memory. Your knowledge. Truly yours — portable across every AI you use.

The Problem

Your Knowledge Is Leaking Away

AI made you 10x faster at generating knowledge — but your way of saving and finding it is still stuck 10 years ago.

Your Knowledge Is Locked Inside One LLM

The decisions, preferences, and insights you've built up in Claude? Switch platforms and they're gone. Account banned, platform shuts down, or you move to GPT-5 — your hard-earned AI context vanishes. Start from scratch.

0%
of AI platform memory is portable

Manual Organization Is Exhausting

Open Notion → pick a folder → write a title → add tags → paste content. 5 minutes per knowledge entry, 10 entries a day = 50 minutes — pure manual labor.

50min
wasted daily on manual organizing

Saved but Can't Find It

"I noted something about user growth earlier..." Search 'growth', get 30 results, none of them right. Because you wrote it as 'PMF validation strategy'.

keyword searches find what you actually want

How it works

Three Steps to a Living LLM Knowledge Base

From input to retrieval, fully AI-driven. You just focus on thinking.

01

Frictionless Input

Just say it naturally

Say 'remember this' in any AI chat, or let MCP auto-capture. Zero friction, zero extra steps.

02

AI Auto-Structures It

No manual categorization

AI automatically extracts titles, categories, tags, and vectorizes. Every piece of knowledge is indexed and ready to retrieve.

03

Smart Retrieval

Semantic search, not keywords

Vector semantic search — AI finds what's truly relevant. No need to remember keywords, just describe what you're looking for.

Features

A Knowledge Base Redesigned for the AI Era

Not AI bolted onto an old tool — built from scratch for AI collaboration. Your knowledge and memory, always yours.

Core Feature

MCP Native Integration

Read and write knowledge directly in AI chats

Deep integration with Claude Desktop / Web / Code via MCP protocol. No app switching — just say 'remember this' in any AI conversation. Configure once, share across all AI clients.

Voice to Knowledge

One recording replaces manual notes

Upload audio or share from your phone. AI handles three-layer processing: ASR transcription → spoken language cleanup → structured extraction. Commute ideas, meeting notes, book summaries — speak and it's saved.

Supports 100MB+ audio files
Mixed Chinese/English auto-detection
Custom extraction templates
AI-Powered

AI Auto-Structuring

Zero manual categorization

When saving knowledge, AI auto-extracts titles, classifies type (note/insight/tech log/article/reflection), generates tags, and vectorizes. New knowledge auto-discovers and links related existing knowledge.

5 knowledge types auto-detected

Cosine similarity ≥ 0.75 auto-linking

Daily Review & AI Insights

Knowledge isn't just about saving

GitHub-style contribution heatmap tracks your knowledge input. AI recommends what to review based on vector similarity, generating full knowledge base insight reports — find blind spots, identify trends.

Memory Sovereignty

LLM-Native Memory Layer

Your memory, always with you

Through save_memory / recall_memory / get_soul MCP tools, Claude auto-extracts decisions, insights, and lessons during conversations and saves them to your knowledge base. 0.90 vector dedup, auto-categorization, Soul profile export. Switch AI platforms? Memory stays.

Bilingual Interface

Switch between English and Chinese instantly

Full support for English and Chinese UI with URL-based locale routing (/zh/ and /en/). Auto-detects your browser language on first visit. Manual toggle in the top-right corner. Your knowledge base content stays intact across language switches — AI search works regardless of interface language.

AI-Native Architecture

Not a Note App with AI Bolted On
A Knowledge Base Built for AI

AI-native from the ground up: vector indexing, semantic understanding, auto-structuring — every layer designed for AI collaboration.

Vector Semantic Search

Describe your question in natural language, AI pinpoints the answer. No need to remember keywords — 'that counterintuitive insight about growth' still works.

Semantic understanding, not keyword matching

AI Auto-Tagging & Classification

When saving knowledge, AI automatically extracts titles, classifies type (note / insight / tech log / article / reflection), and generates precise tags. You just write, AI handles the rest.

5 knowledge types auto-detected

Related Knowledge Auto-Discovery

When new knowledge is saved, it automatically discovers and links to similar existing knowledge. No manual linking needed — your knowledge network grows on its own.

Auto-linked when similarity threshold met

AI Insight Reports

Analyzes your full knowledge base to identify blind spots, high-frequency themes, and evolution trends. Not just storage — helps you understand your own knowledge structure.

Daily review + smart recommendations + heatmap

Memory Dedup & Reinforcement

Same content won't be saved twice — when vector similarity ≥ 0.90, existing memory is reinforced with updated count and timestamp. The more important a decision, the more reinforced and weighted in search.

0.90 cosine similarity threshold

Soul Profile

Auto-distills your user profile from accumulated memories: background, thinking patterns, work preferences. Export as a System Prompt and paste into any AI platform — it understands you from the first message.

Use Cases

Who Uses KnowMine?

Anyone who works with AI needs a knowledge base that keeps up with AI's pace.

Indie Developers

Debug experience never lost again

Spent 3 hours fixing a weird Docker networking issue. Told Claude Code 'remember this debugging process'. Three months later, hit a similar problem — Claude pulled up the solution immediately.

Claude CodeClaude Desktop

Heavy AI Users

Conversation insights preserved forever

Every day chatting with Claude about architecture, business analysis, creative ideas — generating tons of valuable insights. Before, closing the window meant losing it all. Now via MCP, it's auto-saved. Next conversation, AI connects your past thinking.

Claude WebAI Agents

Content Creators

Inspiration ready when you need it

Spotted an interesting idea, jotted down 'counterintuitive insight about XX trend'. Two weeks later writing an article, searched 'trend' — semantic match found it + 5 related pieces. Article framework assembled itself.

What Users Say

Finally no more switching between Notion and Claude. Say 'remember this' in the conversation, and it's saved automatically.

The voice-to-knowledge feature is incredibly practical. Record during my commute, arrive at the office and it's already a structured note.

After three months, the most surprising thing is the auto-linking — it discovered connections between my knowledge that I hadn't even noticed myself.
