AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.

AI-moderated voice and video interviews that scale survey research to thousands of people at once
An AI moderator generates dynamic follow-up questions when an answer is thin, adding interview depth without a human moderator per session.
Respondents can answer by speaking, recording video, or typing, and teams can embed the same questions into existing survey platforms.
Every response is transcribed, translated, and themed with sentiment scoring and charts ready to drop into a report.
Built-in AI translation and transcription let one study reach audiences across more than fifty languages.
