How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Parabol when facilitating sprint poker estimation sessions matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Free, open-source agile meeting tool for retrospectives, sprint poker, and standups with automated meeting summaries and AI topic grouping.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Parabol is a free, open-source platform built for facilitating agile meetings, with a particular focus on sprint retrospectives alongside estimation (sprint poker) and team check-ins. Its retrospective experience follows a structured reflect, group, vote, discuss, and action workflow compatible with popular formats like Start/Stop/Continue, 4Ls, and Mad/Sad/Glad, plus custom templates. Facilitators get multiplayer drag-and-drop cards, live task editing, timers, dynamic agenda items, discussion threads, emoji reactions, and a large library of retrospective formats and icebreaker questions. At the end of each retro, Parabol automatically generates a meeting summary that rolls up notes and tasks, posts them to a team timeline, and delivers them to attendees via email or Slack so next steps are clear. Its AI capabilities include automatic naming of grouped card clusters and AI topic summaries to speed up synthesis during retros. Parabol integrates with Jira, GitHub, GitLab, Slack, and Mattermost, and because the codebase is publicly available on GitHub, teams can self-host or review how it works. It is used by hundreds of thousands of people across distributed and remote teams. Pricing varies by plan. Check the official website for current pricing.
