Sakana AI adds My Fish memory viewer to Sakana Chat

Sakana AI's My Fish arrives as a window onto a memory feature that shipped in a September update and runs in the background. The company's framing is that Sakana Chat accumulates knowledge with each conversation, learning preferred answer styles, what a user is working on, and important people and places. The new feature does not add memory itself; it exposes it.

The design choices point to a specific concern: memory that is on by default but selective. Sakana Chat does not store every conversation as-is, and instead keeps information judged likely to be useful across conversations, such as a standing preference to answer casually in Japanese, ongoing projects, or facts useful to know about the user. My Fish then sorts that store into categories like profile, preferences and ongoing projects, and adds a heat map that stays visible even when the screen changes, alongside a chronological history of when memories were read and used.

Sakana AI ties the feature to a broader view of AI conversation: because the assistant knows what a user is working on and what answers they prefer, the same question can produce different answers, and a conversation can continue from where the last one left off instead of repeating the same explanation each time. The company says the memory will keep evolving.
