Agents Take Over the PM Grunt Work

Three of today's five are agents shipped inside tools your company already pays for — Amplitude, Linear and Intercom — which makes the adoption question a configuration one rather than a procurement one. The other two take your interviews and your regression suite.

Why it matters for PMsThe funnel drop you would have found at next month's metrics review shows up in Slack with a root-cause hypothesis attached.

Issue triage agents

Linear for Agents

Lets you assign AI agents to Linear issues so they triage incoming reports, answer questions, and open follow-up work.

Why it matters for PMsTriage intake, duplicate detection, and routing stop eating the first hour of your morning before sprint planning.

AI end-to-end testing

Momentic

Builds end-to-end tests from natural-language steps, runs them on hosted browsers and devices, and repairs them when the UI changes.

Why it matters for PMsRegression coverage stops being the reason your release slips a week, so you can ship behind flags more often.

Fin 3

Why it matters for PMsIts resolution gaps become a ranked list of product problems, turning support volume into a real input for your backlog.

Every weekday issue goes out with the brief on all five tools. It arrives in every issue of the no-card trial — 7 weekday issues for an email address and no card. (A card plan, $10/month or $96/year, also unlocks it right here on the page.) Start the trial below — or read a complete brief on five tools, free.

Get tomorrow's issue with the call on each tool.

You just read the whole issue, free — and it stays free. The Adoption Brief is the other half: adopt, pilot or skip on each of the five tools, the price a 20-person product org really lands on, the SSO and data-risk line, and a 3-line pitch you can paste into #product. Leave your email and the next 7 issues arrive with all five briefs attached — no card, nothing to cancel.

  • A one-word verdict on every tool — adopt, pilot or skip — with the reason in one sentence.
  • The real price a 20-person product org lands on, not the headline tier on the pricing page.
  • The integration and data-risk line: which plan SSO needs, the SOC 2 posture, where your roadmap and customer data ends up.
  • A paste-ready 3-line pitch for #product, so making the case costs you nothing.
