A FEW GOOD QUESTIONS
Less mystery.
More clarity.
Is the full version really free?
Yes. All features are part of one free version. There is no paid tier or upgrade to unlock the tools shown here.
Is Terso made for Mac?
Yes. Terso is a desktop utility for macOS. It is not a Windows, Android or iPhone app.
Does this demo access my files?
No. The interactive preview uses sample data stored in the page. It cannot inspect your disk or delete anything from your Mac.
Can I review files before cleaning?
The cleanup flow lets you select categories, review the selection and confirm the action. Try it in the interactive preview above.
What does the AI section show?
It brings local AI models, caches and application data into one view. The demo includes examples such as Ollama models and Hugging Face caches.
Can I switch between dark and light?
Absolutely. Use the Dark / Light control above the app preview to explore both appearances.
A fresh start.
Without starting over.
Make a little room for what’s next.
