What is Goldfish?

According to its official website, Goldfish is "a little AI memory that lives on your device". It remembers what you've done, so you don't have to repeat explanations of the context. It's very lightweight to use: press the right Option key on a Mac or the right Shift key on Windows to bring it up anywhere you can type, and directly generate responses, drafts or summaries that match your tone and style.

Who is it for?

Operations and support staff who switch between IMs, emails, and work orders dozens of times a day.
Developers who use Cursor and Claude Code to write code and hate pasting context repeatedly.
Project managers who need to quickly organize scattered context into responses.
Knowledge workers who are sensitive to data leakage and prefer their memories to be stored on their local devices.
Content creators who want AI outputs to be more in line with their own tone.

Key features

Replies in your tone

The official website states that pressing the shortcut key will generate replies that sound like they were written by you.

Chat with your memory

Ask direct questions about what you’ve seen, for example, "Help me catch up on progress" and "Find the missing links".

Context in every AI

The official version states that it can connect with tools such as Claude, Claude Code, Cursor, and Codex, eliminating the need to repeatedly explain the background.

On-device memory

The official website states that your memories are stored on your device, AI requests are not retained at all, and they are not used for training.

Anywhere you type

Not tied to a specific app; you can summon it anywhere you can type.

Free during beta
