Annotation Issues

Notes Disappearing

Symptoms: Create notes, they’re gone on page refresh.

Solutions:

  1. Annotations are URL-specific — check you’re on same page

  3. Verify notes in “View Annotations” panel
  4. Clear browser cache may remove notes — export regularly

Can’t Create Notes

Performance Issues

Extension Making Chrome Slow

Symptoms: Chrome lags when AssisT is enabled.

Solutions:

  1. Disable features you’re not using
  2. Reduce number of simultaneous features active
  3. Check Chrome Task Manager (Shift+Esc) for memory usage
  4. Restart Chrome to clear accumulated memory
  5. Disable on heavy sites (social media, video sites)

High CPU Usage

Symptoms: Fan spinning, computer hot when using AssisT.

Solutions:

  1. TTS with highlighting uses significant CPU — reduce on weak devices
  2. Disable features when not needed
  3. Close other resource-heavy tabs
  4. Some features + complex pages = high load

Page Load Delays

Symptoms: Pages take longer to load with AssisT.

Solutions:

  1. Disable “Auto-apply” features
  2. Let page fully load before enabling features
  3. Some features analyze page content on load
  4. Consider using features on-demand rather than always-on

Keyboard Shortcuts Not Working

Shortcut Does Nothing

Symptoms: Press shortcut, feature doesn’t activate.

Solutions:

  1. Check feature is enabled first
  2. Click in page content (not address bar or other UI)
  3. Another extension may use same shortcut
  4. Check shortcut hasn’t been customized differently
  5. Some shortcuts only work in specific contexts (modals, etc.)

Shortcut Conflicts

Symptoms: Wrong action happens when pressing shortcut.

Solutions:

  1. Go to AssisT Settings → Shortcuts
  2. Change conflicting shortcut to new key combination
  3. Check Chrome’s global shortcuts: chrome://extensions/shortcuts
