Example: Priya and Marcus, a climate policy report

Example: Sana, a student with an app idea

Example: Sana again, out of credits before a deadline

  1. Priya works in Claude. She is halfway through the slides, deep in a chat only she can see.
  2. She saves to Leftoff. One line: save this to Leftoff. Her AI writes what was done, what was decided and what comes next.
  3. Then her tokens run out. No time to write a summary. She pastes the chat into Leftoff instead. It costs her nothing.
  4. Marcus opens Cursor. Different person, different AI. He types one line: catch me up.
  5. And carries on. The summary lands with Priya's decisions and his next step. Nobody had to explain anything.
  1. Sana has an idea in ChatGPT. An app that splits rent fairly. One line keeps it: save this to my inbox.
  2. She researches it in Perplexity. Perplexity pulls the idea from her Leftoff and goes looking for competitors.
  3. The research is saved too. Three apps and one gap, saved next to the idea, labelled with the AI that found them.
  4. She opens Claude to build it. One line: catch me up. Claude reads the idea and the research before it writes a word.
  5. And carries on. Three AIs, one memory. She never explained the idea twice.
  1. Sana runs out of credits. Halfway through the build, her Claude hits its usage limit. The deadline does not move.
  2. She borrows Jay's laptop. Jay's Claude, her own Leftoff. She makes a 24 hour guest link and pastes it in as a connector. Nobody signs in.
  3. Her context loads. Catch me up brings back her decisions and her next step. Nothing of Jay's mixes in.
  4. She works and saves. The save lands in Sana's private project, noted as made from Jay's Claude.
  5. Then she revokes it. One click in Leftoff ends the guest link. Nothing of hers stays behind.

Every decision, every next step and every hand over stays with the project, whichever AI wrote it.

01 · How it works

Four small habits, one shared memory

Leftoff sits behind the AI tools your team already uses. Nobody changes how they work. They just stop losing the thread.

01

Save

Say save this to Leftoff. Your AI writes a short record with your name on it.

02

Summary

Any AI reads one page about the project instead of you pasting old chats.

03

Catch up

Only what changed since you last looked, in whichever AI you open next.

04

Shared folder

Leftoff notices new, changed and removed files and puts them in the summary.

02 · Why it stays cheap

A long history, a short summary

Every bar is a message in the example project's history. Your AI only ever reads the highlighted part, so cost stays flat however long the project runs.

The summary: up to 1,200 tokens

Example history: 41,870 tokensIn the summary: 1,104 / 1,200 tokens

05 · Questions

Questions, answered

What is Leftoff?

Leftoff is a shared memory for teams who work with AI. Anyone can save what they did and what comes next from any AI tool, and the next person or AI picks up from there with a full history.

Can I use Leftoff on my own?

Yes. Private projects are your own memory. Save an idea in one AI, research it in another and build it in a third, or give a friend's computer a guest link when you run out of credits. Your context goes where you go.

Which AI tools does it work with?

Any AI that can connect to a custom MCP server, such as Claude, Claude Code, Cursor, Codex, ChatGPT, Perplexity or Grok. We test most with Claude and Claude Code. If an AI has no connectors, copy your summary and paste it in.

What is a guest link?

A guest link is a private link for a computer or AI account that is not yours. It opens one project, ends by itself after 2 hours, 24 hours or 7 days, and you can revoke it in one click. Nobody signs in on the borrowed machine.

Does Leftoff read my chats?

No. Your own AI writes a short summary only when you ask it to save. Nothing is captured automatically. If you paste a chat to hand over, that is your choice and it stays inside the project.

Will it use up my tokens?

Very few. A summary holds at most 1,200 tokens of your project and a catch up 1,500. Leftoff itself never calls an AI model, so there is no hidden model cost behind it.

Who can see a project?

Only the people you invite, each with a role of owner, editor or viewer. Anyone outside the project sees nothing. You can invite people from other companies by email.

What if a save is wrong?

Withdraw it. The save stays in the history marked as withdrawn, with who withdrew it and why, and it is left out of every summary.

Can a note from a teammate trick my AI?

Leftoff labels every note as quoted data from a named teammate, and tells your AI never to follow instructions inside notes. This lowers the risk. It is not a guarantee, so review what your AI does with anything it reads.

What if I run out of tokens before I save?

Paste your chat into Leftoff. It trims the text without using an AI, flags it in the next summary, and a teammate's AI writes the summary on your behalf.

How much does it cost?

Free is free, for personal use and small teams, with no credit card. Campus and Business are arranged with each university or company for now. See Plans above.

Stop starting from zero

Connect your AI in about a minute. Your next chat picks up where the last one stopped.
