Install from the zip

Store publication is in preparation. Meanwhile you can install the early version manually — a few short steps.

Your browser: Chrome
Download Chatsavo

After you load it, the browser may show a warning about developer mode. Close the warning and do not click Disable — that turns Chatsavo off. This is normal for the zip version.

Early version 0.3.6, November 7, 2026. Requires Chrome/Chromium 116+ or Firefox 140+. It does not update itself: download a new version here and follow the instructions below. Store publication is in preparation — from there, updates will install automatically.
  1. 1
    Unzip the archiveUnzip the download into a folder. That folder must contain manifest.json. Do not delete the folder: the browser loads the extension from it.
  2. 2
    Turn on developer modeCopy chrome://extensions and paste it into the address bar — a website cannot open that link. In Edge use edge://extensions, in Yandex Browser browser://extensions, in Opera opera://extensions. Switch on “Developer mode”.
  3. 3
    Load the unpacked extensionClick “Load unpacked” and pick the folder from step 1 — the one that contains manifest.json. Pin the Chatsavo icon to the toolbar.
  4. 4
    Open ChatGPT or ClaudeThe Chatsavo panel appears on the left. Open 2–3 old chats: the extension remembers the text of every chat you open.
  5. 5
    Find somethingType a word in the search field at the top of the panel — the result opens at the exact message. Alt+Shift+F is optional: it only puts the cursor in that field. On Russian Windows, Alt+Shift switches the keyboard layout.
