Works with Claude, ChatGPT, and any MCP agent
Pick up where you left off.
LeftOff is a personal research memory layer. It captures your research flow — pages, AI chats, documents — organizes it into resumable threads, and serves it to any AI you use.
Not a knowledge base. Not bookmarks. Not notes.
It manages your thinking progress — not your saved content.
Research is fragmented. Your memory shouldn’t be.
The restart tax
Every time you reopen a research topic, you burn 20 minutes reconstructing where you were, what you concluded, and why you stopped. Starting from 70% is harder than starting from zero.
The lost source
“I read something about this three months ago” — but it’s buried at item #400 of your browser history, mid-way through an AI chat, or in a tab you’ll never find again.
The repeat-yourself tax
Switch AI tools and you re-explain everything. Your context is locked inside each platform’s walls: ChatGPT’s memory doesn’t know Claude, and neither knows your agents.
How it works
Capture, passively
A browser extension quietly records your research signals — pages you actually read, text you select, AI conversations you have. No screenshots, no screen recording. Import your ChatGPT history and get a map of your last 90 days on day one.
Threads, not bookmarks
AI organizes your stream into research threads: a timeline per topic — sources, follow-up questions, conclusions, and the exact point where you stopped. Merge, split, and correct with one click.
Resume in any AI
Connect via MCP and say “continue my research on X” in Claude, ChatGPT, or any agent. It recalls your progress, your conclusions, your open questions — and picks up from the breakpoint.
90-day research map
Import once, and see what you’ve actually been researching — including the threads you forgot.
Resume briefs
Progress, conclusions, open questions — generated per thread, consumed by you or your AI.
Capture you control
One-click pause. Blocked domains never leave your browser. Incognito is never touched.
Your data, portable
Plain-text export (Markdown + SQLite), one-click delete. Switch AIs freely — your memory follows you.
