Features

Everything you need, one tap away

Arc packs powerful AI features into a lightweight floating sidebar that's always accessible.

📋

AI Summary

Get instant AI-powered summaries of any screen — articles, emails, notifications, PDFs, and more. Save, share, or listen aloud via text-to-speech.

🔍

Smart Extract

Automatically pull out events, reminders, deadlines, contacts, meeting links, locations, and even verification codes (OTP) — each tappable to act on.

💬

AI Chat

Have a contextual conversation with AI about what's on your screen. Arc uses your screen content and screenshot as context. Save chats to revisit later.

📞

Call Insights

Upload call recordings (M4A, MP3, WAV, and more) to get full transcripts, speaker-labeled summaries, and extracted action items.

📝

AI Writer

Draft text right in any input field. Four modes: Rewrite, Fix Grammar, Reply to conversations, and Create Post — with tone and length options.

🃏

Flashcards

Turn any screen content into study flashcards. Swipe through them in the viewer, mark what you know, and focus on what you don't.

📱

Floating Sidebar

Swipe from the screen edge to expand Arc in any app. Drag to reposition. Choose which apps Arc appears in with per-app control.

⚙️

Custom Actions

Create your own AI actions with custom prompts, or browse 250 community actions across 16 categories — with upvoting and search.

🔊

AI Read

Listen to a summary of any screen. Arc reads and summarizes the content, then plays it back via text-to-speech — perfect for multitasking.

💾

Save Content

Save any screen to your library with a single tap — with optional screenshots. Build a personal knowledge base without generating a summary.

🌐

Community Actions

Browse and add AI actions created by the community. Discover workflows for productivity, writing, translation, and more — available in 10 languages.
