Pro Mode & Seamless OAuth Continuity

Every answer challenged.
Every thread preserved.

Standard mobile apps give you a single unverified pass—and force you to start a new chat if your free tier runs out. TinCan challenges its own assumptions before executing, and keeps your conversation history locally owned across every account switch.

  • 5-Stage Pro Mode Loop: Initial Answer → Challenge → Final Answer → Implement → Loop.
  • Plan vs. Build Separation: Inspect safely with read-only tools in Plan Mode before switching to Build Mode.
  • Zero-Loss OAuth Switching: Switch between ChatGPT, Antigravity, Puter, OpenRouter, or local GGUF mid-conversation without losing a single message.
Stage 01 — Formulate a concrete initial architecture and proposed solution for your task before touching any files.

Voice, Vision & Model Freedom

Intelligence across every modality.

Speak naturally and review your words inside an editable draft before sending—never accidentally send a half-finished voice prompt. Supports offline Local Whisper models and multiple cloud STT profiles.

Read responses aloud with Android system TTS by default or add multiple AI TTS profiles. Generate images, edit reference images, or use a vision bridge model so text-only LLMs can understand photos, sliced video frames, and selected PDF pages.

Sign in via OAuth with OpenAI (ChatGPT), Antigravity/Google, Puter, or OpenRouter. Bring any custom API key and base URL, or run quantized .gguf and multimodal mmproj models 100% offline on your phone.

Share an entire conversation branch with colleagues so they get the full context, or fork any conversation to explore a new direction without altering the original. Includes ChatGPT & Claude history import.

GitHub Release Assets
View on GitHub ↗ Latest Release Notes →
What happens when my free-tier OAuth account hits its limit?

Switch to another OAuth account (ChatGPT, Antigravity, Puter, or OpenRouter) or swap to an API key / local GGUF model. Because conversations are stored on your device, you resume the exact same thread without losing context.

How do multi-provider profiles work for Voice, TTS, and Images?

Audio Transcription (Local Whisper or cloud STT), Read Aloud (Android system TTS default or AI TTS), and Image Generation each support multiple saved profiles so you can switch providers without re-entering credentials.

Should I download TinCan-v2.apk or TinCan-v2-Android-APK.zip?

Both contain the exact same signed v2.14.2 ARM64 installer. Use the .zip file if Chrome on Android pauses at 100% while scanning the .apk. Ignore GitHub’s auto-generated Source code archives.

Can I inspect files safely without the agent making changes?

Yes. Switch to Plan Mode to restrict TinCan to read-only inspection across your files, sandbox, and SSH servers before approving any changes in Build Mode.

Don’t rent your workflow. Own it.

Break free from mobile chat limitations and account lock-in. Download TinCan and run a full Linux, SSH, MCP, and local/cloud AI agent on your Android device in minutes.
