Syntac

Syntac is built for code work away from a laptop. It gives one Android app enough local context to review a project, ask an AI model for changes, inspect generated edits, and run command-line checks through an Android runtime.

Core behavior:

Project folders stay on your device. Chat history and tool results stay on your device. API keys and OAuth credentials stay in Android secure storage. Model requests go only to the provider you configure. Shell commands run only for the active project. Main features Local project browser with recent projects and search. Chat-based coding agent with streaming responses. File tools for reading, writing, editing, listing, deleting, and searching project files. Bash tool support through a packaged Android runtime or Termux bridge. Provider support for Google Antigravity / Cloud Code Assist, ChatGPT Codex OAuth, Grok, and OpenAI-compatible APIs. Markdown/code rendering and expandable tool result cards. Startup, runtime, provider, and storage diagnostics. Built-in update check with stable, beta, and nightly channels.
