Goldfish
Goldfish is an AI memory app for macOS that helps you reply, write, summarize, and continue with context already on your Mac. It stores memory locally and writes in your tone.
Overview
Goldfish is an AI memory app for macOS that helps you write, reply, summarize, and continue from the context already on your Mac. It is designed to work inside the text fields you already use, so you can get help without manually gathering context first.
The product positions itself as a local, searchable memory layer that captures what is happening across apps, tabs, and documents. The homepage emphasizes writing in your tone, while the FAQ explains that the stored memory stays on your Mac and that the app can also connect to Claude Desktop through local MCP.
Features
Tone matching
Goldfish learns your writing style across apps, people, and situations so its output reads more like your own writing.
Local memory from ongoing work
It captures context as you work and turns it into searchable local memory, reducing the need to restate the same background repeatedly.
Workflow awareness
The app can surface repetitive workflows, forgotten follow-ups, and nudges based on patterns it notices over time.
Multiple access points
Goldfish can be used from the aquarium in the notch and can also connect to Claude Desktop through local MCP.
Use cases
Context-aware replies
Use Goldfish when you are answering email or chat messages and want the reply to reflect the thread, documents, and recent context without retyping background details.
Writing with local context
Use it to draft or continue writing in an editor, browser, or note app when the surrounding work should shape the next sentence or paragraph.
Workflow recall
Use it to keep track of recurring tasks, follow-ups, and workflows that you repeat across apps, so the app can surface patterns and reminders over time.
Claude Desktop companion
Use the Claude Desktop connection when you want your Mac’s local context available inside Claude through local MCP.
Searching your work history
Use the app as a local memory layer for browsing past work and the auto-generated wiki mentioned in the FAQ when you need to revisit what you did or why.
