Zincan
We test Mindy on zincan.com — here's what we learned in the first quarter.
Our newsletter draft turnaround dropped from a half-day project to a 20-minute review pass. Same week, same writer.

Results
Zincan is an AI venture studio. We write a lot — product updates, founder essays, customer stories — and the archive grew faster than our memory of it. Writers were spending half their drafting time re-reading old posts to make sure they weren't repeating themselves, contradicting themselves, or missing the obvious link back.
We tried the obvious things first: a custom GPT trained on the archive, then Notion AI's question-answering. Both were fine at generic prose and useless on our terminology — they'd invent stack names, mis-attribute quotes, and confidently hallucinate facts about our own roadmap. We needed something grounded in the actual archive, not adjacent to it.
Mindy is that thing. She reads the archive on every question, cites the originating post, and refuses to answer outside what she's actually seen. We've been running her against zincan.com since the beginning of the quarter. This is what changed.
Before & after
Concrete shifts the team can point at, not vibes.
How they use Mindy
The day-to-day surfaces, not the marketing pitch.
Daily content review
Every morning Mindy posts a thread in #content with what shipped yesterday, what's still in draft, and what evergreen posts are getting unexpected traffic. The thread takes 90 seconds to scroll; the half-hour Monday meeting it replaced did not.
Newsletter drafting
We ask Mindy for a candidate draft each Friday afternoon. She pulls from the week's posts and last quarter's most-engaged archive, drafts in our voice, and includes inline citations. The human editor's job became review-and-trim instead of stare-at-a-blank-page.
Linking strategy
When a writer is mid-draft and wants to link back to a previous piece, they ask Mindy for the relevant prior posts. She returns the three best candidates with the exact paragraph each one would slot in alongside — no more open-tab archaeology, no more accidentally re-writing the same essay.
What we don't use her for
Honesty section: we don't use Mindy for original analysis, hot takes, or anything that needs a human point of view. She's the institutional memory, not the voice. We also don't use her on draft posts that aren't yet committed to the archive — she only answers from published material, so unpublished context is on us.
