Arc Documentation
Learn how every feature works — from the floating sidebar to call insights. Detailed guides with step-by-step flows.
Floating Sidebar
Arc's core navigation mechanism - a persistent, system-wide overlay that provides instant access to all AI features from any screen on the Android device.
AI Summary
Generate instant, concise summaries of any on-screen content using advanced AI. Save, share, listen via TTS, and discuss further via AI chat.
AI Writer
A system-wide text assistance tool that helps you write, edit, and respond to messages across any Android application with four modes: Rewrite, Fix Grammar, Reply, and Create Post.
AI Read (Text-to-Speech)
Convert any on-screen text into natural-sounding speech with TTS. Includes automatic language detection, multiple voice options, playback controls, and background playback.
Save Content
Capture and store any on-screen content from any Android app for later access. Content is organized into a searchable library with automatic categorization, thumbnails, and source tracking.
Custom Actions
Create personalized AI workflows tailored to your needs. Define custom prompts, choose icons, and run them on any screen content from the floating sidebar.
Community Actions
Browse and add pre-built AI actions from Arc and the community. Discover translation, summarization, fact-checking, and creative workflows with one tap.
Chat with AI
Have context-aware conversations about any content on your screen. Discuss summaries, custom action results, or on-screen content with multi-turn dialogue.
Flashcards
Turn any on-screen content into AI-generated flashcards. Study with an interactive flip mode, track progress, and build a persistent library of study sets.
Smart Extract
Smart Extract intelligently extracts actionable items from any on-screen content with a single tap. Using AI-powered analysis, it identifies events, reminders, contacts, meeting links, locations, verification codes, phone numbers, and email addresses — then provides one-tap actions to add them to calendar, save contacts, copy codes, open maps, join meetings, and more.
My Info Vault
A secure local storage system for your personal and professional information that personalizes AI Writer responses. Create, edit, organize, and delete vault entries (each with a title and content), then selectively include them when generating AI text. Vault data is stored privately on your device and only sent to AI services when you explicitly use AI Writer.
Unread Queue
A content management system that helps you track and organize saved content you haven't read or reviewed yet. It acts as a reading list that automatically populates with saved summaries, content, and flashcard sets, then removes items once viewed. The queue provides a focused view of pending content, encouraging regular reading habits.
Call Insights
Analyze call recordings to get comprehensive transcriptions, summaries, action items, and key insights. Supports two modes: Manual Upload (select audio files for one-time analysis) and Auto Analysis (automatic monitoring of specific folders for new recordings). Transcripts include speaker identification, helping you quickly review important call details without re-listening.
