Own Your AI Thinking.
Save your AI conversations as files you own. Search them, version them, and take them anywhere.
WHY THIS MATTERS
AI conversations are becoming
part of human memory.
Every day, people think with AI.
But that thinking is locked inside closed platforms.
- ✗
You switch from ChatGPT to Claude, and months of context stay behind.
- ✗
You want to find a thought you had with AI last week, but you can only scroll.
- ✗
You cancel a subscription, and years of conversations disappear with the account.
- ✗
You want to continue your work offline, but your memory only lives in someone else's cloud.
- ✗
You want to back up your thinking with git, but there is nothing to back up — just a chat window.
Your AI conversations are not throwaway prompts.
They are part of how you think — and they should belong to you.
LocalThink exists to change that.
WHAT IS LOCALTHINK FORMAT (LTF)
An open markdown standard
for human-AI thinking.
Every LTF file is a plain .ltf.md file — open it in any editor, search it with any tool, and read it like a document, not a database.

## Conversation
**Human:** Why should I save my AI conversations?
**AI:** Because the conversation is not just output.
It is part of your thinking process.
Because LTF is plain markdown with structured metadata, your AI memory becomes:
- ✓
Portable — across ChatGPT, Claude, Gemini, Grok, and any future platform
- ✓
Readable — in any editor — VS Code, Obsidian, GitHub, even a plain terminal
- ✓
Searchable — with any tool you already use — grep, VS Code search, Obsidian, or your terminal
- ✓
Versionable — with git — track how your thinking evolves over time
- ✓
Independent — of any AI provider, app, or company
HOW TO CREATE LTF FILES
One click.
Your conversation, saved.
LTF Builder is a free Chrome plugin that captures conversations from ChatGPT, Claude, Gemini, and Grok and exports them as clean .ltf.md files. Code blocks, tables, and lists are preserved with their original structure.
- ✓
No signup
- ✓
No cloud
- ✓
No AI generation — reads the rendered page and converts to readable markdown
The public Chrome Web Store version supports ChatGPT, Claude, Gemini, and Grok web conversations today. Kimi and more platforms are in development.
Save your AI memory locally, under your control.

The future is not one chatbot.
LocalThink is built around a simple principle:
your AI memory belongs to you.
That means portable files, local-first tools, no mandatory cloud memory, and no platform lock-in.
The future is:
- Personal AI environments
- Portable AI memory
- Local AI runtimes
- AI memory you actually own
LocalThink is building the infrastructure for that future.
