About
Hi, I'm the developer of Arc, an AI sidebar that works inside every app, on Android and macOS.
The problem: to get AI help with a message, you long-press, copy, switch to ChatGPT, paste, copy the answer, switch back, and paste again. Every time.
With Arc: open the sidebar in any app, and Arc already sees what's on your screen. On Android, you swipe in from the edge. No copying, no switching apps.
✍️ AI Writer: fix a reply in three taps
- Rewrite what you typed: Polite, Professional, Rephrase or Shorten. Arc picks up the text from the box you're typing in automatically.
- Reply when you don't know what to say. Arc reads the conversation and suggests a reply.
- Fix Grammar and Create Post for social posts.
- Tap Insert and the text goes straight into your text box. Works in WhatsApp, Gmail, Messages, Slack and any other app.
⚡ Everything else, one click away
- AI Summary: summarize long articles, emails and chats.
- Chat with your screen: ask follow-up questions about whatever is on it.
- AI Read: have any screen read aloud.
- Flashcards: turn what you're reading into study cards.
- Smart Extract and Save Content: pull out the details that matter and save them for later.
🤯 500+ AI actions, and you can build your own
- Create Action: write a prompt once and run it on any screen with one tap, for example "Fact Check", "Find Calories" or "Find a Cheaper Alternative".
- Community Actions: browse and add 500+ actions made by other users, from translation styles to data extraction.

Free to try on Android and macOS. I'd love your feedback. What action would you build first?
