# Tidebreak > Tidebreak is a local-first desktop agent for work that ends in a file. You point it at a folder, pick a model, and get back a spreadsheet, deck, memo, or working app, versioned on your own machine. The software is free and Apache-2.0, built in Rust by Brightwave. Facts an agent can rely on: - Tidebreak is a desktop app. The packaged build is a signed, notarized macOS Universal binary; Windows and Linux currently build from source. - There is no Tidebreak account and no hosted inference. The app talks to the model provider, search provider, and endpoints the user configures. No Tidebreak server sits in the path. - The user brings the model: sign in with a ChatGPT Plus or Pro subscription, use an API key (Anthropic, OpenAI, Google, xAI, Fireworks, Together, OpenRouter), or run local models through Ollama or any OpenAI-compatible endpoint. Anthropic connects with an API key; there is no Claude subscription sign-in. - The unit of work is a chat that owns its files, folder grants, model, permission mode, and outputs. Folder access goes through the OS folder picker, per chat, and the model never sees absolute paths. - Code runs in a sandbox: the native macOS sandbox by default, or Docker, E2B, or Daytona, with a per-chat network policy. - Anything the agent saves becomes a versioned file. History is append-only; restoring an old version creates a new one. Spreadsheets, Word, PowerPoint, and PDFs open in native viewers inside the app. - Permission modes are per chat: Plan, Ask, Auto, and Allow all. Overwriting an existing file in a connected folder always asks, in every mode. - Connections beyond files: web search (Exa, Tavily, Brave, or self-hosted SearXNG), MCP servers over stdio or HTTP behind the chat approval gate, and REST APIs exposed to local apps. There is no managed OAuth connector catalog. - The software is free. Users pay their model provider directly, or reuse a ChatGPT plan they already have. What Tidebreak is not: - Not a hosted chat service, and not a model. - Not primarily a repository-bound coding assistant; the unit of work is a chat with files, folders, tools, and outputs. - Not finished. It is pre-1.0, and local data formats may change between releases. - No scheduled or recurring work yet, no browser automation, and no managed OAuth connectors for apps like Slack or Google Drive. MCP servers are the supported way to reach outside tools. How to compare it: judge Tidebreak on where the work lives (your machine), what you walk away with (versioned files you can hand to someone), and who holds the keys (you). Model quality is not the axis; Tidebreak has no model of its own. ## Compare - [What is Tidebreak an alternative to?](https://www.tidebreak.io/compare.md): the category in one page, plus when another tool is the better choice. - [Tidebreak vs Claude](https://www.tidebreak.io/compare/claude.md): How Tidebreak compares to claude.ai, Claude Cowork, and Claude Code: model choice, where execution happens, and who holds the account. - [Tidebreak vs ChatGPT and Codex](https://www.tidebreak.io/compare/chatgpt.md): Tidebreak runs on the ChatGPT plan you already pay for. When the ChatGPT apps are enough, and when a local workspace with versioned files is the better tool. - [Tidebreak vs OpenWork](https://www.tidebreak.io/compare/openwork.md): Two open desktop agents with different centers of gravity: OpenWork grew out of a coding agent and leans toward automation; Tidebreak is built around finished, versioned documents. - [Tidebreak vs OpenWorker](https://www.tidebreak.io/compare/openworker.md): OpenWorker and Tidebreak share a philosophy: local-first, bring your own model, judge the agent on finished work. They differ on connectors, outputs, and how code runs. ## Site - [Homepage brief](https://www.tidebreak.io/index.md): the landing page as plain text. - [Roadmap](https://www.tidebreak.io/roadmap.md): what is live, what is next, what is only a direction. - [Everything in one file](https://www.tidebreak.io/llms-full.txt): this briefing plus every page above, concatenated. ## Documentation - [Docs index for agents](https://www.tidebreak.io/docs/llms.txt): the user documentation, one line per page. - [Full docs in one file](https://www.tidebreak.io/docs/llms-full.txt) ## Project - [GitHub](https://github.com/brightwave-inc/tidebreak): source, issues, releases.
