Free Mac beta · a personal project in development
Read first.
Then try it.
The Mac beta is free. No newsletter and no email form on this page. Read the notices and check both boxes to unlock the version currently published in the update file.
The iPhone app is currently available in German only. iPhone, iPad and Apple Watch are in testing.
Your own storage
Texts, recordings, PDFs and pictures stay in your chosen local or cloud storage. Downloading does not give us access to them. The app account is separate.
AI and internet
Local groundwork does not need generative AI. The current Mac beta needs sign-in at startup. Dictation depends on Apple speech recognition. AI features process task-related data through online services.
Optional costs
Downloading starts no paid subscription. Optional AI or research features may cost money or use credits. Check the terms displayed before use. AI results can be wrong.
This website counts aggregate page views and download clicks. A click does not confirm a completed download.
