In case of an unplanned shutdown, all conversation gets lost without any track

Google Antigravity

The case:

Open a new conversation in Antigravity IDE.

Chat with AI.

Never close the conversation (no close, no switch to another one).

Computer shuts down unexpectedly (a crash).

Restart the computer.

Look for the conversation.

It doesn’t show up in the IDE (but it still lives in the brain folder – .gemini\antigravity-ide\brain).

Please do a fix. I’ve lost so many conversations this way.

Hi @anti, Welcome to the Forum!

We tried reproducing this issue using the provided steps, but we were unable to replicate the behavior on our end.

If you are still experiencing this, please share a few details to help us investigate further:

  • Your operating system and version?

  • Your specific Antigravity IDE version?

  • How the unexpected shutdown occurred (e.g., power loss, system crash, or forced shutdown)?

  • Is the conversation completely missing from the list, or does it fail to open when clicked?

  • Any error messages or log outputs displayed after restarting?

  • The exact steps followed and prompts used before the shutdown occurred?

  • A screenshot showing the issue, if available?

  • Your operating system and version?

    • Windows 11 Pro

  • Your specific Antigravity IDE version?

    • 2.1.1

  • How the unexpected shutdown occurred (e.g., power loss, system crash, or forced shutdown)?

    • I found my PC restarted in the morning. Probably due to the auto-installation of Windows updates.

  • Is the conversation completely missing from the list, or does it fail to open when clicked?

    • It is not available in the conversation list, but available under the brain folder.

  • Any error messages or log outputs displayed after restarting?

    • No.

  • The exact steps followed and prompts used before the shutdown occurred?

    • PC was in sleep mode, I was not working.

  • A screenshot showing the issue, if available?

    • N/A

Thank you.

Don’t Worry — Your Raw Conversation Data Is NOT Lost!

If your conversation history suddenly disappeared after a crash, power outage, or IDE update, here is what actually happened:

What Caused This?

During an unclean shutdown or version update, the Antigravity IDE’s internal index databases (chat.ChatSessionStore.index and trajectorySummaries) can silently reset to empty.

The Good News: Your actual conversation files (.pb / .db) are still 100% intact on your hard drive at:

  • Windows: %USERPROFILE%\.gemini\antigravity-ide\conversations\
  • macOS / Linux: ~/.gemini/antigravity-ide/conversations/

Only the UI index mapping was wiped — the actual chat history files were not deleted!

How to Recover All Your Lost Conversations

An open-source database recovery tool was built by the community to scan your hard drive, locate all surviving conversation files, and rebuild the IDE’s index database so all your chats reappear in the sidebar.

  • Upstream Core Recovery Tool: ag-donald / Antigravity-Database-Manager (by Donald R. Johnson) — Rebuilds indices and recovers lost chats across Windows, macOS, and Linux.
  • Extended Fork (Includes Windows URI Fix): IshekKhal / Antigravity-Database-Manager (by Abhishek Khanra) — Contains the complete recovery suite plus an extra fix (fix_workspace_uri.py) for the Windows “Select where to open conversation” URI encoding bug.

Quick Recovery Steps

  1. Close Antigravity IDE completely.
  2. Download or Clone the Repository:
    git clone
    cd Antigravity-Database-Manager
  3. Run the Automatic Recovery Command:
    python antigravity_database_manager.py recover
  4. Reopen Antigravity IDE: All your past conversations will reappear in your sidebar!

(Note for Windows Users: If you also experience the “Select where to open conversation” popup dialog when clicking past chats, you can run python fix_workspace_uri.py to fix Windows drive-letter URI encoding).
