Rephlo - The AI Workspace Inside Every App for Windows, macOS & Linux

What is Rephlo?

Rephlo (pronounced "re-flow") is a desktop AI workspace for Windows, macOS, and Linux that lives in your system tray and works inside every app you already use. Select text in any desktop application — your email client, code editor, browser, word processor, or chat app — press a single hotkey, and the AI runs in place without copy-pasting or switching tabs. But Rephlo is more than a text rewriter: it's a connected workspace with multi-turn chat, document-grounded Knowledge Spaces that answer from your own PDFs, docs, code, and notes (retrieval-augmented generation with on-device embeddings), and Visual Intelligence that analyzes any region of your screen you capture. It supports 8 bring-your-own-key (BYOK) AI providers plus a hosted option, a library of 500+ expert-crafted commands, an AI Prompt Builder, and a fully offline mode with Ollama.

What Makes Rephlo Unique?

• An AI workspace in every desktop app, not a browser tab: Unlike ChatGPT, Claude, or Gemini, Rephlo lives in your operating system. The same hotkey works in Outlook, Slack, VS Code, Notion, Word, Terminal, and any other application — chat, your own documents, and screen-aware vision, with no window to copy into and out of.
• Answers grounded in your own files: Document-grounded Knowledge Spaces use on-device embeddings to retrieve the right passages from your PDFs, Word files, code, and notes — so the AI matches your voice, project, and context instead of producing generic output.
• Screen-aware Visual Intelligence: Capture any region of your screen and a vision model analyzes what it sees — debug an error, read a chart, or extract text from an image, right in your flow.
• Bring your own key, no lock-in: Connect your own OpenAI, Anthropic, Google, Groq, xAI, OpenRouter, Ollama, or OpenAI-compatible keys — or run the hosted option. Switch the model per task: cheap for simple, smart for hard, with zero vendor lock-in.
• Runs fully offline and private: Pair Rephlo with Ollama to run everything locally on your own hardware, with a zero-telemetry option — keeping regulated and sensitive material on-device. Opt-in privacy redaction (PII masking) is in beta; image generation and article writing are on the roadmap.
