Take a real-time pulse of the room. Run live consultations during hearings, town halls, or briefings to align stakeholders without the back-and-forth of email rounds.

Audit-ready exports

Document every interaction. Export questions, votes, and engagement records in one click to keep records, briefings, and compliance responses defensible.

PDF/PPT support

Keep your existing content working for you. Upload your PDF and PowerPoint presentations seamlessly, maintain your visual identity, and add powerful interactive elements without starting from scratch.
