Turn long chats and documents into compact AI memory.
Upload a conversation, notes or a document. LISA Nexus keeps its meaning in a fraction of the size, as a LISA token any AI can pick up from. Your Library keeps them all, online.
Free: 1 compression a day, no sign-up. No credit card to start.
How it works
Three steps, a few seconds each.
Drop or paste
A chat export, meeting notes, research, a transcript: text, Markdown, JSON or Word, up to a million characters.
Choose how
Pick the AI provider, how many key points (anchors) to keep, and what to focus on: decisions, code, tasks, ideas…
Carry it anywhere
Download the LISA token and give it to Claude, ChatGPT, Gemini or any AI: it picks up where you left off.

Your text goes only where you choose
Pick the AI provider for each compression. Your text goes to that provider only, on API terms that exclude training on it.

Smaller, and you can check it
In this example, 2,500 tokens became 216. Every token carries a SHA-256 integrity hash and a governance score that shows how much of the meaning was kept.

One Library for everything
Compressions from Nexus, files you upload and conversations sent from the LISA extension live together. Search by words or by meaning, open and read any conversation, tag and star it, share a read-only link, write a report, or certify it with a signed proof of when it existed.
