RetroStack vs ScatterSpoke

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.

ScatterSpoke helps teams collect feedback and decide what to improve through surveys, retrospectives and Ask. Its AI-assisted retrospectives produce summaries, takeaways and action items in a format teams can share. Teams can choose from a library of more than 20 classic retrospective formats or make custom ones. Asynchronous retrospectives automate feedback collection, and integrations with Jira, Slack and Microsoft Teams connect it with team workflows. In Microsoft Teams, users can create or pin retrospectives in a team space. ScatterSpoke says its AI is built and hosted in-house, and customer data is not shared with major AI providers or used to train other large language models. The free plan includes one seat, unlimited static surveys and responses, 10 one-time Agent Surveys, 50 one-time Ask credits, basic signal detection and MCP access. Pro costs $29 a month per seat for up to five seats; Business costs $149 a month and includes five seats. ScatterSpoke offers 45-day trials and can discuss custom trials through a 30-minute call.
