- An AI notepad that turns your meeting audio and rough notes into structured, searchable summaries.
- WHY IT MATTERS FOR PMS
- Customer calls become a queryable research base, so discovery insights survive past the week they happened.
Our take, from the rated issues
We led Issue 001 with Granola — the subject line was 'Granola makes every customer call searchable' — because it fixes the leakiest step in discovery: the week after the call. PMs are rarely short on customer conversations; they are short on retrievable ones. Granola turns your meeting audio and your own rough notes into structured summaries you can query months later, so the insight from a March call still exists when the June roadmap debate needs it.
What separated it from the other notetakers we tried is the hybrid model. It enhances the notes you type during the call with the detail you missed, so the output reads like a sharper version of your own write-up rather than a generic transcript summary. That matters because the fragments you jot mid-call — the pricing objection, the workaround they demoed with obvious pride — are exactly the parts that carry signal.
One caveat: it works from your own meeting audio rather than a bot that joins the call, so org-wide sharing still takes a deliberate export habit, and strict-consent teams should check their recording policies first. As a personal discovery base it is the strongest we rated this month, and it is the cheapest habit change on the list: install it, take calls, keep the insight.
