Speaker Insight

Separate speaker-level sentiment in multi-person conversations, helping you see which person shifted positive or negative and where those changes happened in the transcript.

Use Cases for Video Sentiment Analyzer

Review Call

Meeting Review

Meeting recordings often hide disputes, hesitation, or sudden mood changes inside long discussions. iWeaver breaks the video into segments, connects sentiment to speakers and transcript lines, and exports a concise outline for follow-up.

Check Meeting

Focus Groups

Focus group videos can produce many opinions at once, making manual comparison slow and inconsistent. iWeaver analyzes each recording, links sentiment to transcript themes, and outputs notes, summaries, and cross-video insights for research teams.
