How to fix Lost conversation history in Antigravity early update app?

by
You updated Antigravity and suddenly your chat history is gone. Only a few old threads show up or none at all, often on Windows 11 and WSL2.

Antigravity chat history missing after update on Windows 11 and WSL2

Users report that after updating to recent Antigravity builds, the conversation list is empty or shows only a couple of very old threads. Restarting the app does not help. Some noted that choosing a workspace folder temporarily restores history, while others recovered history only by reinstalling versions. In one report, over 70 active threads were missing on Windows 11. Versions mentioned include Antigravity 1.18.3 and 1.18.4, with history fully visible again on 1.16.5 but lost once returning to the latest build.

Solution Overview

AspectDetail
Root CauseThe client fails to refresh its local index of chat directories after an update, especially on Windows and WSL2 setups.
Primary FixForce a local reindex by triggering file system read events across the chat storage folders, then relaunch Antigravity.

Restore all conversations by forcing a local reindex

Step by Step Solution

  • Close Antigravity and your editor
– Quit Antigravity completely. If you use it inside your editor, close that window as well.
  • Back up your chat store
– Windows PowerShell “` robocopy “$HOME\.gemini\antigravity\brain” “$HOME\.gemini\antigravity\brain.backup” /E “` – Linux or WSL2 Bash “` cp -a ~/.gemini/antigravity/brain ~/.gemini/antigravity/brain.backup “`
  • Trigger read events across all chat folders
– This nudges the watcher to reindex your conversations on next launch. – Windows PowerShell “` $root = “$HOME\.gemini\antigravity\brain” if (Test-Path $root) { Get-ChildItem -Directory $root | ForEach-Object { # Read each subfolder to trigger filesystem events Get-ChildItem -Force $_.FullName | Out-Null } } else { Write-Error “Chat root not found at $root” } “` – Linux or WSL2 Bash “` ROOT=”$HOME/.gemini/antigravity/brain” if [ -d “$ROOT” ]; then # Recursively read without printing to console find “$ROOT” -type d -exec ls -A {} \; >/dev/null 2>&1 else echo “Chat root not found at $ROOT” >&2 fi “` – Path reference from reports “` ~/.gemini/antigravity/brain “`
  • Relaunch Antigravity
– Start Antigravity again and give it a minute. Your conversations should repopulate as the index refresh completes.
  • Optional set a workspace folder
– Some users regained history after setting a workspace folder first, then relaunching. In Antigravity or your editor, open a folder and keep it as the active workspace before checking history.

Alternative Fixes & Workarounds

  • Reinstall an older build then update again
– Several users restored history by installing 1.16.5, confirming history, then installing the newest build again. – PowerShell with Windows Package Manager “` winget install antigravity –version 1.16.5 –force “` Launch Antigravity and confirm your history is visible, then upgrade “` winget upgrade antigravity “` – Note that some reported success only when updating to the very latest point release. Check your installed version after upgrade.
  • Stay on 1.16.5 temporarily
– If the update re breaks history, remain on 1.16.5 until a fixed build is posted. Back up your chat folder first.
  • Choose a workspace folder
– A few users regained history visibility after picking a workspace folder inside the app or editor, then restarting.
  • Confirm you are on a supported build
– One December build displayed that it was no longer supported. Update to the newest stable version. If you also run export flows with design tools, this resource can prevent related failures during upgrades: Read More: Fix issues exporting code to Figma with Antigravity

Troubleshooting Tips

  • Verify the chat directory exists
– Windows “` Test-Path “$HOME\.gemini\antigravity\brain” “` – Linux or WSL2 “` [ -d “$HOME/.gemini/antigravity/brain” ] && echo “OK” || echo “Missing” “`
  • Check WSL2 location
– If Antigravity runs in Windows but your chat store lives under WSL2 home, make sure the app points to the same user profile area. Copying the folder from WSL2 to Windows profile may not be necessary, but confirm the exact profile used.
  • Permissions and antivirus
– Ensure your user account can read the chat folders. Temporarily pause antivirus if it blocks file access while you run the reindex step.
  • Give it time after launch
– After the read event script and relaunch, wait a minute for indexing to complete before concluding that history is missing.
  • Still no history
– Repeat the read event step, then try the install older then update path method shown above. If your setup involves MCP or service keys that influence project context and storage, confirm they are valid and loaded correctly: Read More: MCP API key setup for Antigravity Stitch

Best Practices

  • Back up the chat store regularly
– Keep a scheduled copy of ~/.gemini/antigravity/brain or the Windows equivalent before updates.
  • Pin a known good version
– If your workflow depends on chat persistence, hold on a stable build until release notes confirm a fix.
  • Keep a dedicated workspace folder
– Use a consistent workspace location, then relaunch the app so watchers re attach predictably.
  • Export important threads
– Periodically export or copy essential conversations to a safe location.
  • Watch release notes
– Check the latest notes before upgrading. If a history fix is mentioned, update promptly.

Final Thought

For most users, forcing a local reindex of the chat folders restores the entire conversation list in minutes. If that does not work, the install 1.16.5 then update path has been effective for many Windows and WSL2 setups, bringing history back without data loss. Additional references
