This update is all about making the app smarter and less frustrating to use. It matters to anyone who uses Grok for complex coding or AI tasks, especially if you run multiple agents at once. You will spend less time fighting with the interface and more time getting actual work done.

What's new

  • Dashboard summaries: The main screen now gives you a quick recap of what the AI just did, so you don't have to scroll up to check.
  • Better extension menus: Add-ons are now grouped alphabetically with collapsible sections, making them easier to find.
  • Smarter background tasks: When a background AI is working, the main AI is now reminded to keep going on your original request instead of just waiting around.
  • Easier session connections: You can jump back into a running session without having to re-read the whole chat history, and you can cleanly close sessions when you're done.
  • Less annoying startup: If you open the app outside of a specific coding project folder, it won't bother asking you which folder to use.
  • Dedicated feedback box: Typing /feedback now opens a special window to send your thoughts, instead of just typing it into the chat box.
  • Smarter dark/light mode: The app can now automatically detect your screen theme even when you're using remote connections (like SSH) or terminal multiplexers (like tmux, which lets you manage multiple terminal windows).
  • Clearer permissions: When the app asks for permission to run a script, it shows you the whole script clearly instead of faded bits. If a command is really long, you can press Ctrl-F to expand it and read it all.

Improvements

  • Tables fit your screen: Markdown tables (grids of data) now adjust their text to fit inside narrow windows instead of getting cut off at the right edge.
  • Better memory usage: Duplicating a massive chat session no longer eats up a ton of your computer's memory.
  • Faster exits: Closing out of an empty session is now instant, even if your internet connection is slow.

Fixes

  • Fixed broken screenshots: Tools that return images no longer ruin or drop screenshots when the file size is large.
  • Fixed lost messages: If you hit "send" really fast or sent messages while a background task was running, your earlier messages used to get lost. Now they stick around.
  • Reliable stop button: Pressing Escape or the stop button now actually stops background tasks from restarting the AI.
  • Fixed freezing workflows: Trying to run many tasks at once (parallel workflows) used to launch hundreds of tasks and freeze the app. Now it works smoothly.
  • Cleaner error messages: Instead of dumping confusing computer code (raw JSON) on your screen when an API (the connection to the AI server) fails, you now get a clean, readable banner.
  • Fixed terminal glitches: Exiting the app no longer messes up your terminal's settings. Also, typing "exit" or "quit" on the main screen actually closes the app now, instead of starting a new chat.
  • Better text copying: When copying languages like Chinese or Japanese, the app no longer misses characters at the very beginning or end of what you highlighted.
  • Fixed login issues: The app no longer skips logging in if it finds a bad or invalid API key in your system settings.
  • Smoother dashboard navigation: Navigating the dashboard after starting a new chat or deleting an old one now works properly without getting you stuck.
  • Fixed code restores: Restoring your code from a large or "shallow" git repository (a folder of saved code) no longer gets stuck forever.
  • No more interrupting recaps: The app no longer pops up automatic summaries in the middle of your new prompts while it's busy working.
  • Fixed menu keys: Pressing Enter on a slash command (like /help) now actually runs it. Tab and Escape also now work consistently across all pop-up cards.
  • Fixed remote resumes: Resuming a remote chat now only restores the conversation by default, instead of trying to reload all your code too, which used to cause 404 errors.
