Not another chatbot
General AI assistants don't know your files, meetings, or screen history. GrepMind does — with citations.

Why GrepMind
The knowledge you need is already on your Mac.
Other tools require you to start from scratch. GrepMind starts with what you already have — your files, recordings, screenshots, and meetings — and makes them searchable, citable, and actionable.
Not another note editor
You don't need to write notes first. GrepMind builds your knowledge base automatically from existing files and recordings.
Not just meeting notes
Meeting tools forget your context after the call. GrepMind connects meetings to your documents, images, and screen history.
Product
Your private memory for real work.
GrepMind is not another blank editor. It starts with the knowledge you already have: local folders, PDFs, images, recordings, videos, meetings, and the screen moments you choose to save.
Every answer is grounded in sources — you can jump back to the exact file, page, timestamp, transcript, or screenshot behind the result.
Capture everything you allow
Index selected folders, documents, photos, audio, video, meetings, and screenshots with clear controls for what stays out.
Understand across formats
Combine OCR, transcription, metadata, semantic search, entity extraction, timelines, and knowledge graph signals.
Answer with evidence
Ask natural-language questions and get concise answers with citations, context, related sources, and follow-up paths.
Create from memory
Turn your knowledge base into reports, meeting summaries, HTML visualizations, PPT outlines, and message drafts.
Core Workflow
From scattered context to finished work.
Connect sources
Select local folders, media libraries, meeting recordings, and optional screen memory sources.
Build private index
GrepMind extracts text, transcripts, visual cues, timestamps, entities, and semantic relationships.
Ask and verify
Search by natural language, filter by source or time, and inspect the citations behind every answer.
Ship outputs
Generate project reports, research briefs, meeting follow-ups, visual pages, and presentation drafts.
Privacy Model
Local-first, permissioned, and inspectable.
GrepMind is designed for sensitive work. Local indexing is the default. Cloud models are optional, and the app explains what context is sent before it leaves your device.
Source control
Choose folders, media, meetings, and screen capture scope.
Visible recording
Audio and screen memory require explicit permission and clear status indicators.
Model choice
Use local models by default or opt into external models such as DeepSeek with explicit consent.
Delete and revoke
Pause capture, remove sources, delete indexes, and withdraw consent at any time.
Advanced Roadmap
Agent Mode: a proxy that knows your work.
The long-term version of GrepMind can assist in meetings, understand voice and text context, draft replies for Feishu, WeChat, email, or other work channels, and act only within rules you approve.
The principle is simple: GrepMind may draft freely, advise privately, and act with approval. Anything sent to another person shows the content, recipient, account, and source context first.
Prepare replies, meeting talking points, and follow-up messages from your knowledge base.
Listen during permitted meetings, surface relevant sources, and suggest questions or answers in real time.
Send messages, create tasks, and update records through Feishu, WeChat, or email after explicit confirmation.
Run low-risk approved routines with audit logs, limits, and an emergency pause button.
Use Cases
