Sakana AI added a feature called My Fish to Sakana Chat, its chat service, that shows what the assistant has stored about each user, when it drew on those memories and how they relate to one another. The memory system itself is not new.
Sakana AI introduced memory on September 17, alongside the rollout of its Fugu Max orchestrator model to all Sakana Chat users. That version, which works with both the Namazu and Fugu Max models, let people review stored items from the settings screen and switch the feature off, and it applies only to conversations held after the update. My Fish, opened from Sakana Chat's Memory settings, adds a dedicated screen with three views.
| View | What it shows |
|---|---|
| Overview | Memories grouped into categories such as profile, preferences, current projects and favorite topics, each with its fact count, read count and last-used time |
| Connections | A map around a central fish: recently used memories sit closer, frequently used ones appear larger, and lines join memories that showed up in the same reply |
| History | A timeline of every read and write, with the exact facts added by each write |
A heatmap at the top of the screen marks when Sakana Chat used memories or learned something new. In the Connections map, a memory not used in 30 days or more is shown faded, a sign it may be going stale. Opening any memory lists its individual facts and the conversations they came from, with a link back to the original chat.
Memory activity also surfaces during a conversation. When the assistant reads or saves a memory while composing an answer, a small chip appears in its thinking process, with text along the lines of "Checked memory: Trip to Spain, Hiking" or "Learned something new: Osaka marathon." Selecting a chip opens My Fish at that memory. On phones, tapping a node in the map opens a drawer from the bottom of the screen while the graph shifts to keep the node in view.
Memory is on by default, though Sakana AI says it does not keep conversations wholesale. It targets details likely to matter across chats, such as a standing preference for casual Japanese replies or an ongoing project, and users can turn it off in settings at any time. Sakana AI calls visibility the first step and says it is exploring better ways to decide what is worth remembering and to update memories as a user's situation changes.
My Fish opens from the account menu at the bottom of the sidebar, under Settings, then Memory, then "View memories in My Fish," on web and mobile.
