Common Issues
Quick fixes for common problems.
Shortcuts Don't Work
1. Is Tessel running?
Look for the Tessel icon:
- Mac: Top right menu bar
- Windows/Linux: Bottom right system tray (click the arrow to expand)
If you don't see it, open Tessel from your applications.
2. Another app might be using the same shortcut
Try a different shortcut:
- Open Tessel
- Go to Transforms
- Click on the shortcut
- Press a new key combination
3. Tessel needs permission (Mac only)
- Go to System Settings → Privacy & Security → Accessibility
- Find Tessel and turn it ON
- Restart Tessel
4. Restart Tessel
Sometimes a quick restart fixes things:
- Right-click the Tessel icon
- Click Quit
- Open Tessel again
Transform Does Nothing
Check what's in your clipboard
The transform might not match what you copied. For example:
- "HTML to Markdown" needs HTML code, not plain text
- "Remove Background" needs an image, not text
Copy again
Sometimes the clipboard gets confused. Just copy your content again.
Try Clean Text first
If text transforms fail, try "Clean Text" (Ctrl+Alt+4) first to clean up any hidden characters.
Image Transforms Fail
Image too big?
Keep images under 10 MB. For larger images, resize them first.
Right format?
Tessel works best with PNG and JPEG images.
Actually an image?
Make sure your clipboard actually has an image:
- Screenshot: Use the screenshot tool
- From browser: Right-click image → Copy Image
- From file: Open in Preview/Photos and copy
AI Transforms Don't Work
"No API key"
You need to set up an API key first. See AI Setup.
"Invalid API key"
- Go to Tessel Settings
- Check your API key is correct
- Make sure there are no extra spaces
"Rate limit" or "Quota exceeded"
- Wait a minute and try again
- Check your API provider dashboard for credits/limits
Taking too long?
AI transforms need internet. Check your connection.
Tessel Won't Start
Mac: "Can't be opened"
- Right-click Tessel in Applications
- Click "Open"
- Click "Open" in the popup
Windows: SmartScreen warning
- Click "More info"
- Click "Run anyway"
Linux: Won't run
Install dependencies:
sudo apt install libfuse2 libwebkit2gtk-4.1-0 libgtk-3-0
Make it executable:
chmod +x Tessel_*.AppImage
Tray Icon Missing
Windows
Click the arrow (^) in the system tray to see hidden icons. Tessel might be there.
Mac
Check your menu bar. It might be hidden behind other icons.
Linux
Install the AppIndicator extension:
sudo apt install gnome-shell-extension-appindicator
Log out and back in.
Everything is Slow
Close other apps
Tessel runs faster with fewer apps open.
Restart Tessel
- Quit Tessel
- Open it again
Clear the cache
