Chorus – All AI, One Place

Your keys. Your models. Your choice.

Chorus is a free-to-use BYOK (Bring Your Own Key) AI app. Connect your own API keys to use multiple free and paid AI models in one place. Chat, compare answers, work with documents and turn ideas into useful tools, without switching between apps.

Chorus has no app subscription. Free model access depends on each provider's API eligibility and usage limits. Paid model and search usage may incur separate provider charges.

One Workspace, Multiple AI Models Connect supported AI providers or compatible gateways, then choose a model for each task. Keep your conversations, documents, notes and projects together as you explore different models.

Explore Free API Options Browse providers offering free API access, limited free quotas or starter credits where available. Check their current requirements and expiry dates. Free Models Only helps restrict requests to recognised no-cost models, and local allowance tracking helps you plan your usage. Providers control availability, quotas and prices.

Chat, Compare and Create Get streaming answers, attach images and documents, organise chats into projects and branch a conversation to explore another answer. Compare models side by side. Use voice input with a supported transcription provider and listen to replies with your device's speech features.

Turn Captures Into Action Chorus Lens turns receipts, event details, checklists and saved posts into editable cards. Extract Latin-script text locally on Android or use a compatible vision model. Review source quotes, correct fields, save notes, export receipt data or prepare a calendar file.

Build Tools You Can Keep Using Create budgets, checklists and weighted comparisons with Interactive Mini Tools. Change inputs and see calculations update locally. Start with a template or ask a model for a revision. Review changes before applying them, save your tool and restore previous versions.

See Different Perspectives Chorus Council asks two models for independent answers, then a reviewer compares them. Explore agreements, differences and evidence gaps. Keep the result with model identities and source material. Agreement between models does not guarantee accuracy.

Remember Why and Watch What Changes Save decisions, reasons and source quotes in Remember Why. Search your records locally or ask a model to help find relevant reasons. Personal Radar watches public HTTPS pages and keeps change excerpts. Android background timing depends on system, battery and network conditions.

Make It Yours Choose Clay, White, Light, Dark or system appearance. The interactive Chorus character follows your theme. Add the animated Android home-screen widget for quick access to chat and voice. Save prompts and reusable assistants, choose chat memories, or use private chats without saved conversation history. Optional web search uses your own supported search connection.

Your Connections, Your Control API keys are encrypted on your device. Saved chats and workspace records stay locally; content you choose to process goes to your selected AI or search provider. View token usage, available cost estimates and connection health. Export backups to keep your work; keys are excluded. Review and report unsafe AI content in Chorus. See the privacy policy for authentication, reports and SDK data handling.

Getting Started A verified Chorus account is required. Cloud AI needs internet and your own working provider API key. A provider's chat subscription may not include API access. Templates and local calculations work without an AI request. Features vary by model and provider. Review important AI answers, extracted values and exports.
