Estimioo
4.6AI-powered planning poker, retrospectives and standups for agile teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a 41-template sprint retrospective board and async daily standups into one shared workspace. The centre of gravity is still estimation, but the retro module is now a real one: one-click templates, a 2–25 minute session timer, per-card thumbs-up voting, synced icebreakers, ambient audio, and a Claude-powered summary that returns team mood, key themes and ranked action items. What it is not is a facilitation suite — retro cards are attributed rather than anonymous, and there is no grouping, no dot-vote budget and no action-item owners or carry-over between sprints.

Retro Rabbit
4.4Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool that lets teams capture notes throughout the sprint from Slack or the web app, then runs the retro on a synced board with drag-and-drop grouping, voting and assignable action items. The CarrotIQ AI layer is gated to the Pro AI plan. No public changelog and no visible feature change since April 2025 — ask for a roadmap before committing.
Full review →Summary

Estimioo — pros
- + Genuinely cheap — flat <strong>$7/workspace/mo</strong> with unlimited participants, plus a usable free tier
- + 41 one-click retro templates, a 2–25 minute session timer and per-card upvoting — all verified in a live board
- + Unusually fun for the price: 340+ synced icebreakers, six ambient soundscapes and 16 live emoji reactions
- + One-click Claude retro summary returns team mood, key themes and ranked action items with <em>Add all to board</em>
- + Jira connects by OAuth or API token with JQL backlog import; guests join by link or QR with no signup
Estimioo — cons
- − Retro cards are <strong>attributed</strong> — author name and avatar on every note, with no anonymity option anywhere in the product
- − No grouping or clustering, no dot-vote budget, no action-item owners or due dates, and no carry-over between retros
- − Slack and Teams are clipboard-copy buttons rather than integrations; Jira write-back is still on the roadmap, and there's no API, webhooks or MCP
- − No SOC 2, ISO 27001, DPA or data-residency option, and the privacy policy was last updated April 2025 — the quote-only Enterprise tier's SSO claim is unverified
- − No independent coverage (no G2, Capterra or Product Hunt listing), and the site's own social proof contradicts itself — <em>450+ teams</em>, <em>183 agile teams</em> and <em>3000+ teams</em> all appear
Retro Rabbit — pros
- + Genuine Slack-first workflow — notes get captured in Slack throughout the sprint, not just at retro time
- + Reduces recency bias by collecting feedback continuously instead of in a 5-minute silent write
- + Simple, opinionated UX with drag-and-drop grouping and dot voting
- + CarrotIQ covers grouping, action-item suggestions and retro summaries on the $40/team/mo Pro AI plan
- + Flat per-team pricing with unlimited users, and CSV/XLSX/PDF export on every tier including Starter
Retro Rabbit — cons
- − Slack is the only chat/issue-tracker integration — no Jira, Teams, Confluence, GitHub, Linear or Azure DevOps
- − No health checks, team radars or longitudinal trend reporting
- − No org-level dashboards, cross-team rollups or action kanban
- − No public API, webhooks or MCP server — data leaves only as a file export
- − Enterprise controls are thin: SSO is Enterprise-tier only, no SCIM, no audit logs, and the privacy policy carries no GDPR or CCPA commitments
