In their own words
FreeRetrospectives
FreeRetrospectives is a free web workspace for sprint and company retrospectives. Teams can collect notes anonymously in the room view, group them, vote, and turn discussion into action items. Live chat supports replies, reactions, links, and image sharing. The site lists 100 templates for topics including delivery, incidents, quality, team health, remote work, and continuous improvement. Action tracking records owners, due dates, blockers, and unresolved items across retrospectives. AI sprint recaps can summarize themes, sentiment, and decisions, then suggest follow-up actions for a facilitator to review. Integrations include Jira, GitHub, Linear, Slack, Trello, Notion, Azure DevOps, and CSV, alongside API, MCP, and webhooks. Users sign in with Google, GitHub, Jira, or LinkedIn; joining a room also requires a code and may require a password. The privacy policy says relevant text may be sent to internal or third-party AI providers, while users can avoid AI features. The site does not claim formal compliance certifications or uptime guarantees.
RetroStack
RetroStack is a collaborative board app for agile retrospectives, brainstorming, planning, and group decision-making. Participants edit the same board live across phones, tablets, laptops, and desktops, using six ready-made formats or custom boards. Voting limits can be set per section to 1, 2, 3, 5, or 10 votes, or left unlimited. Users can join anonymously with the full feature set, and no account is required to start a board. AI analysis can provide team sentiment insights and key themes, and generate action items and meeting recaps. Boards can be shared through private links or exported as PDF or JSON. The free plan is free and lists web, iOS, Android, and Mac access without sign-up. RetroStack says data is encrypted in transit and at rest, and user content is not used to train AI models; requested analysis is processed through OpenAI. The service may limit board creation, notes per section, votes per session, and AI analysis requests per day. Email support has a stated response time within 24 hours.
