Estimioo
4.8AI-powered planning poker, retrospectives and standups for agile teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker and a 42-format sprint retrospective board into one shared workspace. Estimation is still the centre of gravity, but the retro board caught up in September 2026: optional Writing → Voting → Discuss phases with a shared timer, anonymous sessions or single anonymous cards, host-led card grouping, a 3–10 vote budget, action-item owners, and a carry-over banner fed by the host's personal action tracker. A Claude-powered summary returns team mood, key themes and ranked action items. What it still lacks is blind brainstorming, recurring retros, health-check trends and any retro export beyond a clipboard recap.

Retro Rabbit
4.4Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool: the team drops notes into a Slack channel or the web app all sprint long, then runs the retro on a live synced board with drag-to-group, dot voting, a shared timer and assignable action items that carry over to the next retro. The CarrotIQ AI layer is gated to the $40/team/month Pro AI plan. Four-person vendor, Slack is the only integration, and there is still no public changelog.
Full review →Summary
Estimioo scores 4.8 overall and is best for small, distributed agile teams who want AI-assisted planning poker and a capable 42-format retro board in one workspace for a flat $7 a month — and who can live without blind brainstorming, recurring retros, health-check trends or real Slack, Teams and retro-side Jira integrations. It offers a free tier.
Retro Rabbit scores 4.4 overall and is best for slack-centric agile teams that want retro notes captured continuously through the sprint and a lightweight live or async board — and that don't need Jira, health checks or a procurement checklist. It offers paid plans from $30/team/mo.

Estimioo — pros
- + Genuinely cheap — flat <strong>$7/workspace/mo</strong> with unlimited participants, plus a usable free tier; guests join by link or QR with no signup, in five UI languages
- + A real facilitation flow: optional Writing → Voting → Discuss phases with a done-writing signal, host-led card grouping, a 3–10 vote budget and owners on action items
- + Anonymous sessions (or a single anonymous card on a named board), and open actions from earlier retros resurface as a banner when the host starts the next one
- + Unusually fun for the price: 340+ synced icebreakers, twelve ambient and music tracks, emoji reactions on cards and an in-session chat with GIFs
- + One-click Claude retro summary returns team mood, key themes and ranked action items with <em>Add all to board</em>
Estimioo — cons
- − No blind brainstorm — cards appear to everyone as they're written, so the retro page's <em>write first, discuss second</em> pitch rests on the facilitator, not the tool
- − Follow-through belongs to the host, not the team: carry-over runs through a personal action tracker, nothing recurs or can be scheduled, and Team Radar scores don't trend across retros
- − Thin integrations: Slack and Teams are copy-to-clipboard buttons, Jira is planning-poker only, Linear is still "on the way", and a retro exports nothing but a pasted recap — no API, webhooks or MCP
- − No SOC 2, ISO 27001, DPA or data-residency option, and while Enterprise lists SSO, the shipped sign-in offers only Google and email
- − Social proof is entirely unattributed — <em>450+ teams</em>, a <em>4.8</em> rating and a logo wall naming Accenture, Deloitte, Thoughtworks and Xero, with no G2, Capterra or Product Hunt listing to corroborate any of it
Retro Rabbit — pros
- + Genuine Slack-first capture — notes land in the channel throughout the sprint, so the board opens full instead of starting with silent writing
- + Board covers the basics properly: drag-to-group with editable group names, dot voting with a configurable 1–50 vote budget, a shared pause/resume timer, and a per-user anonymity toggle
- + Action items carry forward — a dedicated <em>Old / Unresolved Items</em> tab plus per-room and per-person trackers, with Slack reminders to assignees
- + A GIPHY picker on notes that the marketing site never mentions — the one bit of levity on an otherwise plain board
- + Flat $30/team/month with unlimited users (3 teams of 8 = $90/mo), and CSV/XLSX/PDF export on every tier including Starter
Retro Rabbit — cons
- − Slack is the only integration — no Jira, Teams, Confluence, GitHub, Linear or Azure DevOps, and no public API, webhooks or MCP
- − No health checks, team radars or sentiment tracking; the only longitudinal view is a notes-per-day bar chart per room
- − AI is two calls — a per-retro summary and one action-item suggestion. The site's <em>intelligent note grouping</em> claim has no counterpart in the shipped web app
- − Enterprise controls are thin: SSO/SAML is Enterprise-tier only, no SCIM, no audit logs and no SOC 2 of its own. The privacy policy carries no GDPR or CCPA commitments and says retro feedback is not shared with third parties, the Slack Marketplace listing answers <em>uses large language models: no</em> and <em>has a dedicated security team: no</em>, and neither says where CarrotIQ processes notes
- − No free tier and no public changelog, from a four-person vendor whose marketing site has not changed since early 2025
