What it does
A system-wide text assistant: finish a sentence with a trigger like ?fix and the accessibility service replaces it in place, inside WhatsApp, Gmail, X, Notes or wherever you were typing — no copying into a chatbot and back. Triggers are yours to define for correction, translation or tone, backed by Gemini, Groq or any OpenAI-compatible endpoint, with several keys rotated automatically when one hits a limit, and offline text replacements that need no network at all. Keys are encrypted in the Android Keystore, though the text you trigger on does go to whichever provider you picked. MIT, also on F-Droid.

- Do I need to install anything or write code to use SwiftSlate?
- You install it like a normal desktop app. No command line involved.
- Does SwiftSlate work on a phone?
- Yes, it works on a phone.
- Can I use SwiftSlate commercially?
- The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
