Version 2.4 makes Second Brain better at finding the specific memory you meant while reducing irrelevant connected context. Your existing memories benefit automatically. There is nothing to recapture or reindex.

Sharper recall

• Better recovery of specific, older, and easily buried memories

• More useful answers to why and how questions

• Fewer close-but-wrong results and less graph noise

• Strong existing matches remain protected while promising buried memories get another chance

This release came out of the issues, the bug reports, and in a few cases other people's code.

The main change: you decide how your brain remembers now, not us. Seven controls in a settings window, in plain English rather than variable names. How much recent memories outrank older ones. What counts as a duplicate. How far to follow connections. Three options each, with an honest note about the tradeoff. Changes apply to your next search. No redeploy.

I realized the backend had gotten a lot smarter, but the dashboard still felt like looking at a database.

Most knowledge tools put the connection work on you. Tag this. Link that. File it in the right folder. Organize it or lose it.

But the whole point of using AI is to spend less time on busywork, not more.

Second Brain builds its knowledge graph automatically. When you save a memory, the system extracts the people, projects, decisions, and concepts mentioned. It scans the existing graph for related entries and creates links where it finds meaningful overlap.

A few examples of what this surfaces in practice:

Most people already have context somewhere. Meeting notes in Notion. Decisions in a doc. Research in a database.

Second Brain v2 can sync directly from Notion, so you do not have to re-enter everything manually.

When we launched Second Brain for the first time, we somehow finished #3 Product of the Day.

The second launch finished #4.

When an AI system decides what context to surface, you are usually trusting a black box. You do not know exactly why one memory ranked higher than another, or how the system handles edge cases.

Second Brain v2 is fully open source. The recall scoring, the graph traversal, the conflict detection logic, all of it is readable.

When your AI remembers something, it treats every piece of context with the same weight. A decision you made six months ago sits alongside a rough idea you were brainstorming yesterday. There is no way to say "this is settled" versus "this was just thinking out loud."

That matters more than it sounds.

Until now your MCP endpoint was protected by URL obscurity. The random Worker URL generated at setup made it hard to guess. That worked, but it was not real security. @phillipadsmith pointed this out and shipped a PR to fix it. v1.7 adds proper OAuth so the endpoint is explicitly protected, not just obscure.

Merging also got smarter. When two memories overlap, v1.7 now weighs importance, so high-signal context does not get flattened into a near-duplicate. This one came directly from feedback by @anand_thakkar1 during the launch.
