Goldfish

Goldfish

Goldfish is a local Mac AI memory app that captures your work context and drafts replies in your own tone when you press the Option key. Goldfish runs on your machine and builds a searchable memory of your work from the context it captures, stored in a local database. Pressing the Option key anywhere you type lets Goldfish write, reply, summarize, or continue text in your personal tone and with your accumulated context. The company says data stays local — no one, including the makers, can see it — with AI requests routed through Azure OpenAI at zero retention, and it exposes context to Claude Desktop via a local MCP integration. Native builds exist for macOS and Windows.

Production credibility: Goldfish is made by two Swedish developers, Joel and Kaspian, building from San Francisco, per the site — founder identities are given only as first names, and it is early-stage and free during beta. It launched on Product Hunt around June 2026 with a number-one day rank and awards including number two Product of the Week and of the Month for June, at roughly 1,000-plus upvotes; that is attributed to Product Hunt. The homepage displays used-by logos including Y Combinator, Harvard, and ElevenLabs; those are vendor-presented logos rather than verified endorsements, and there is no disclosed funding.

Key Features

• System-wide reply and compose triggered by the Option key in any text field
• Writing that learns and matches the user's personal tone and style
• An auto-generated personal memory searchable across captured work context
• Local, on-device storage of that memory rather than the cloud
• AI processing via Azure OpenAI with vendor-stated zero retention and no training
• A local MCP integration that feeds context into Claude Desktop
• Bundled task assistants for writing and other help
• Native builds for macOS and Windows

Ideal Use Case

Goldfish fits knowledge workers and founders who write many messages and want fast, on-brand replies without copy-pasting into a chatbot. It suits privacy-conscious users who prefer their context stored locally rather than in a cloud service. It is a weaker fit for someone wanting a mature, paid product with support guarantees, since Goldfish is an early free beta from a small team.

How Goldfish differentiates

Unlike cloud writing tools such as Grammarly or a raw ChatGPT window, Goldfish keeps its memory on-device and is invoked inline via the Option key rather than in a separate app. Versus prompt tools like Raycast AI, its emphasis is a persistent personal-tone memory that also pipes into Claude Desktop over MCP.
