Let’s see what Sakana Chat remembers: a new memory visualization feature, “My Fish”

Sakana AI has added a new feature to Sakana Chat called My Fish, and the point is simple: the assistant’s memory is no longer hidden in the basement. Users can now see what Sakana Chat remembers about them, when those memories were used, and how different memories connect to each other.

That matters because Sakana Chat’s memory is doing more than saving trivia. The system is meant to carry useful context across conversations, like how someone likes answers phrased, what they’re working on, and the people, places, or projects that keep coming up. My Fish puts all of that in one place instead of leaving it buried in the background.

The feature is split into a few views. A heatmap at the top shows when memory was read or when something new was learned. An overview groups memories into buckets such as profile, preferences, current projects, and favorite topics. There’s also a connections view that lays memories out like a map around the central fish, plus a history view that shows every read and write in time order.

Each memory comes with its own little dossier: how many facts it contains, how often it has been read, when it was last used, and which conversations it came from. Open one and you can jump back to the original chat. Sakana AI also added small chips inside the response-building process, so users can see moments like “Checked memory: Trip to Spain, Hiking” or “Learned something new: Osaka marathon” without leaving the conversation.

The company says memory is on by default, but not every conversation is saved as-is. It focuses on information that may be useful across chats, and users can turn memory off in settings if they want to stop it from being used. My Fish is available on web and mobile through Settings → My Fish, and Sakana AI says this is only the first step in making memory smarter and more useful over time.
