Second Brain now creates its own memories.
Since our May 31 launch (v1.6), we shipped two major releases:
v1.7 added OAuth 2.0 on the MCP endpoint and importance-score-aware smart merging, so high-value memories resist being collapsed by near-duplicates.
v1.8 added semantic compression: a nightly cron job synthesizes entries with 10+ tags into net-new memory digests. Source entries are penalized in recall scoring, making the synthesized memory the authoritative version.
This is a meaningful architectural shift, not a UI update. Also shipped: full REST parity for recall/forget/list, and one-command client setup scripts.

At some point, more memories stop being useful. The challenge becomes figuring out which once are worth keeping around.
Hello Rahil 👋 the semantic compression idea sounds really useful because AI memory can get messy quickly when too many small details pile up.
I like that this focuses on the architecture side instead of just adding more buttons. Good memory quality is probably going to matter a lot for AI tools.

How do you decide when a memory is important enough to keep separate versus merging into a larger summary.
The idea of memories creating their own better versions feels similar to how humans naturally keep important lesons and forget small details.
