Ask your company anything

The second half of a second brain: recall. What it takes to answer "why did we decide that?" across months of calls — and why cross-meeting memory is the hard version of the problem.

Search over transcripts is easy to build and disappointing to use. You ask about the pricing decision and get eleven chunks of conversation, six of which mention pricing and none of which tell you what was decided.

The problem is the unit. Chunks of text are what got indexed; what you wanted was a decision, its owner, its reasoning, and whether it survived contact with the next three meetings.

Decisions have histories

Real answers usually span calls. The idea appears in a Tuesday standup, gets challenged in a customer call, gets settled in a leadership sync, and gets quietly reversed a month later. Any one of those meetings in isolation gives you a confidently wrong answer.

So the object we care about isn't the meeting — it's the thread: a decision or a topic tracked across every conversation that touched it, with the moments it changed marked.

Questions worth answering

"Why did we decide that?"
The decision, plus the reasoning that produced it, plus who disagreed.
"What did we promise this customer?"
Every commitment made to them, across every call, still open or not.
"What's still unresolved on this project?"
Open questions raised and never closed — the category that silently rots.
"What did I miss?"
Not a summary of a call you skipped — the parts that affect your work.

Cite or don't answer

Every answer links to the moment it came from — the meeting, the timestamp, the speaker. Partly this is trust: an unsourced claim about what your company decided is worse than no answer. Partly it's practical, because the thirty seconds either side of the answer is usually the context you actually needed.

Status

Recall across a single meeting works today. Cross-meeting threading — the version described here — is what we're actively building, and it's the piece we're most excited about.

The short version

  • Search finds moments; memory reconstructs decisions.
  • The useful unit of recall is the decision and its history, not the transcript chunk.
  • Answers should cite the moment they came from — always.
