LISA guide by SAT-CHAIN

Your AI conversations, kept and carried anywhere.

LISA turns long chats, documents and notes into compact memory you can keep, search and hand to any AI. This guide covers the three tools of the LISA Suite. One license key and one credit balance work in all three.

LISA NexusThis website: compress documents and conversations, and keep your Library.
LISA extensionSaves your chats on 12 AI platforms and hands them off to a fresh session.
Inference ShieldChecks what your text reveals about your technology before you publish it.

STEP 1Get your key

Open LISA Nexus and click the key button at the top right. No key yet? Enter your email under No key yet? and press Email me a key. Your key arrives from no-reply@sat-chain.com within a minute, with 50 free credits. Lost it? Use the same form; we send your existing key again.

LISA Nexus with the key panel open: a license key field with Validate, and below it an email field with an 'Email me a key' button
Paste a key you already have, or get one by email.

Paste the key and press Validate. The button then shows your plan and your credit balance. Buying credits or a plan (see Credits and plans) also emails you a key.

Signed in with a pay-as-you-go key: 450 credits.
The same key works in LISA Nexus, the LISA extension and Inference Shield. Keep it private: anyone with your key can spend your credits.

STEP 2Compress a document or conversation

Drop a file on the box (text, Markdown, JSON, log or Word), or switch to Paste text and paste a conversation, notes or a transcript (at least 100 characters).

Open Options to choose:

  • AI provider: which AI does the compression. Your text goes only to the provider you pick.
  • Semantic anchors: how many key points to keep, from 4 (brief) to 12 (maximum).
  • Focus: all topics, or mainly decisions, code, action items, ideas, problems, research or goals.
  • Save as: the name in your Library.

Press Compress with AI. It takes a few seconds.

STEP 3Use the result

You get a LISA token: the meaning of your text in a fraction of the size, as a small JSON file with its key points (anchors). Each token carries a SHA-256 integrity hash and a governance score that shows how much of the meaning was kept.

Compression results: 11.4× compression, 6 anchors, 2.5k tokens down to 216, governance-verified at 94%, with Download, Save to Library and Process another buttons and a preview of the token
2,500 tokens became 216. The preview shows the anchors.
  • Download LISA token: attach the .json to any AI chat (Claude, ChatGPT, Gemini…) and say "continue from this". The AI picks up where you left off.
  • Save to Library: keep it with your key, available from any computer.
  • Process another: start again.

STEP 4Your Library

The Library keeps everything you saved, on our servers with your key: conversations you sent from the extension, files you uploaded and compressions from Nexus, in one list.

  • Find: search by Words (titles and messages, in any language) or by Meaning (conversations about the same thing, even in other words). Filter by source, platform, tag or ★ starred, and sort by date, title or length.
  • Open a conversation to read it, find words inside it, rename it (click the title), star it or add tags.
  • ⋯ holds the rest: Download, Copy, Compress with AI, Write a report, Share a link, Certify (a signed proof that this exact conversation existed today) and Delete.
  • Tick several to export them together (one .json or a .zip) or delete them.
  • Upload… adds a LISA .json or .jsonl file.

The LISA extension

STEP 5Install and sign in

Install LISA from the Chrome Web Store and pin it to your toolbar. It works on Claude (including Claude Code), ChatGPT, Gemini, Grok, Mistral, DeepSeek, Copilot, Perplexity, HuggingChat, Meta AI and Poe.

Click the LISA icon, then ⚙ Settings (top right of the popup). Paste your key under License Key and press Validate. No key yet? Get one with 50 free credits takes you to the free-key form.

Settings in the extension popup.

STEP 6The floating button

On any supported AI chat, LISA adds an Export to LISA button at the bottom right. The dot on it is the conversation's health: green while the AI keeps up, then yellow and red as a long chat starts to strain its memory.

Click it for the menu.
ItemWhat it does
📋 MarkdownSaves the chat as readable text in your library
📝 LISA-VerbatimSaves every word with integrity hashes: the best format to continue in another AI
🧠 CheckpointCopies a prompt that asks the AI to sum up where you are. Paste it, send it; LISA keeps the answer
🔄 HandoffMoves the conversation to a fresh chat (step 7)
🛡 Inference ShieldChecks the chat before you share it (step 10)

The header shows the message count and an estimate of the tokens used, so you can see a long chat growing.

STEP 7Hand off to another AI

Long chats get slow and forgetful. Handoff opens a fresh chat, on the same AI or another one, and gives it the conversation so far. Tip: run Checkpoint first; the handoff then includes the AI's own summary.

The handoff panel: format LISA (compact), and destinations Claude (fresh session), ChatGPT, Gemini and Grok
Pick where to continue. Choose which AIs appear here in the popup's Settings.

LISA opens the new tab next to yours and attaches the conversation as a file. If the site doesn't accept the file automatically, click the message box and press Ctrl+V (⌘+V on a Mac).

STEP 8Choose what to save

Open Advanced at the bottom of the floating button's menu (click it to unfold). ⚙ Options sets what Markdown, LISA-Verbatim and Inference Shield include: the whole conversation, only your messages, or only the AI's replies. It also sets the Handoff format: LISA (compact: the start and end word for word, the middle compressed) or Markdown (the full conversation, word for word). Options apply to the page you're on and reset when you reload it, so you never save a partial export by surprise later.

Options: include the whole conversation, my messages only or AI replies only; Handoff format LISA or Markdown
Options apply until you reload the page.
Choose messages: a list of messages with checkboxes, All, Mine, AI and None shortcuts, and Markdown, LISA-V and Shield buttons
Choose messages: 2 of 6 selected.

☑ Choose messages… lists the conversation so you can tick exactly the messages you want, then save them or check them with Inference Shield.

A partial save is always labelled: the title says "(AI replies only)" or "(2 selected messages)", and the file itself records that it isn't the whole conversation. When a filter is on, the menu shows "Saving: …" in yellow. Handoff always includes both sides, so the new chat gets the full context.

The suite

STEP 10Inference Shield

Before you publish a blog post, pitch deck or documentation written with AI, Inference Shield shows what it reveals about how your technology works, and can rewrite the risky phrases. Send text to it from the extension in three ways:

  • Select text on any page, right-click, and choose Check with Inference Shield.
  • Choose 🛡 Inference Shield in the floating button menu (the whole chat, or messages you pick with Choose messages).
  • Press 🛡️ on an item in the popup library.

Shield opens in a new tab, signed in with your key, with the text in place. Opening it is free; nothing runs until you press Run.
