How AI helps you in Strella

AI helps at every stage of a study: setting up, running interviews, analyzing results, and sharing findings. Here is each place it helps and what it does.

Strella uses AI across the whole study lifecycle. Some are a chat you talk to; others run automatically in the background. Here's every major place AI helps, stage by stage.

Setting up your study

  • AI-guided setup chat: describe what you want to learn (or upload a brief) and it drafts a screener and a question guide. You keep editing it while the draft takes shape.
  • Build assistant: the right-hand panel in Build. It reads your current draft and helps you edit it: rewrite a question, add a follow-up, suggest a section.

Running the interview

  • AI moderator: conducts every interview by voice. It greets the participant, walks your guide top to bottom, asks dynamic follow-ups, and closes out. It runs in many languages and translates your guide live, and (in beta) can glance at the participant's screen.
  • Automatic transcription: every recording is transcribed with speaker labels, synced to the video, and searchable. Regenerate it if speakers are mislabeled.

Analyzing results

  • Per-interview analysis: each interview gets an AI-written summary, auto-generated notes, and quality-check badges that flag fraud and quality risks.
  • Themes & sentiment: across every completed interview, AI groups responses into themes by objective or by question, scores sentiment, codes open-ended answers into countable categories, and pulls representative quotes.
  • Results AI chat: ask the analyst anything about this study's interviews. It cites its sources and can spin up a report or a highlight reel. See AI chat best practices for how to prompt it well.
  • Multi-project explorer: the same chat, scoped across several studies in your organization, for questions that span more than one.

Sharing findings

  • AI-generated reports: drafts a full writeup (executive summary, participant profiles, theme cards with quotes) and even a cover image. Edit any of it before you share.
  • Highlight reels: every theme has an auto-compiled reel of its source moments; the AI chat can build one on demand too.

Bring your own AI

  • MCP: connect an external AI assistant (Claude, ChatGPT, and others) to your Strella data so you can query your studies from the tools you already use. See API, MCP & assistants.

Things to know

  • AI-generated insights cite their sources. In the analysis, the Results AI chat, and the multi-project explorer, click a quote to jump to that moment in the source interview. (The setup chat and build assistant don't link to interviews, because there aren't any yet.)
  • Analysis only considers completed interviews. The themes, the AI chat, and the explorer all ignore drafts and abandoned interviews.
  • To change how the live moderator behaves, edit Settings → AI moderator. The build assistant edits your guide; it doesn't run the interview.
  • The moderator doesn't pretend to be human. If a participant asks, it confirms it's an AI.
