In their own words
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.
RetroTool
RetroTool is a web tool for running retrospectives with remote or hybrid teams. Teams can start with Mad | Sad | Glad, Liked | Learned | Lacked, or Start | Stop | Continue templates. Participants can draft cards in private sections and move them into a public section. Voting includes dot and secret voting, with controls for the number of votes allowed per participant, column, and card. Teams can turn discussion into action points, assign a responsible teammate, and set a due date. A timer is among the facilitation tools. Paid plans add facilitator-only moderation, readiness checks, read-only locking, and private, invite-only retrospectives; the Company plan adds zero-knowledge encryption with custom passwords. The Anonymous plan costs nothing and keeps data for up to 12 months. Individual costs $10 a month per team, and Company costs $20 a month per team. RetroTool offers a 90-day trial. The maker says u2i first created the tool for its own remote retrospectives before offering it to others.
