The qualitative research repository that turns customer interviews into a roadmap you can defend
Upload video, audio, or notes for each customer call and get a stored recording, full transcript, and structured takeaways in one searchable repository.
Define your own output types and a plain-English prompt per series, so each call surfaces exactly the pain points, opportunities, quotes, or feature requests you care about.
Ask questions about your interviews, themes, and personas in natural language and get answers drawn from your own research with the underlying sources cited.
Insights cluster into evidence-linked themes, while dynamic personas and segments group the people behind each finding so needs can be compared group by group.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
