Miro for Product Acceleration

Miro's new product suite puts AI agents on the canvas to turn research, sticky notes and sessions into briefs, specs and prioritised backlogs.

Why it matters for PMsIt changes the week after a discovery workshop: synthesis and the first draft of the brief come out of the board instead of your calendar.

Support triage agent

Plain Ari

Ari is Plain's customer-facing AI agent that answers and resolves B2B support threads in Slack, email, Teams and in-app chat.

Why it matters for PMsIt thins the shared Slack-channel escalation queue PMs get pulled into, so you see themed bug patterns instead of one-off pings.

Autonomous QA testing

Ranger

Ranger's agents write, run and maintain Playwright tests against your web app, and now re-test fixes produced by coding agents.

Why it matters for PMsIt removes the manual regression pass before release, which is usually the step that pushes your ship date out by a day or two.

Spec-driven development

Kiro

Kiro is AWS's agentic IDE and web agent that turns a written spec into requirements, design and tracked implementation tasks.

Why it matters for PMsYour spec becomes the executable artefact engineers work from, so scope drift between PRD and pull request is visible rather than discovered at demo.

Warehouse-native analytics

Kubit

Kubit runs product analytics and agent-observability queries directly in Snowflake, BigQuery or Databricks without copying event data out.

Why it matters for PMsIf you ship AI features, it lets you analyse agent runs and user journeys on the same governed warehouse data your finance numbers come from.

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.
