How is evidence told apart from interpretation?
Every quote on a theme is checked against the text you pasted. If it appears word for word, it is shown exactly as you wrote it and counts as evidence. The AI's one-line summary of each theme, and all insights, are labelled as the AI's wording. A theme with no quote that checks out is marked Interpretation.
What does "One participant" mean?
The theme has verified quotes from exactly one source. It may still be true and important, but only one person said it, so treat it as something to test with more people.
Why was a quote rejected?
The AI proposed words that are not in your text: a paraphrase, an edited quote, a merge of two sentences, or something the interviewer said. We drop those and show you how many. Rejected quotes are never shown, because they aren't your participants' words.
What should I paste?
Raw words, not your summary: the tool can only check what is in the text. Use one box per participant so that "how many people said it" means something, and keep speaker labels like Interviewer: and Sam: at the start of each turn. You can also load .txt or .vtt files. Add your research question to steer the grouping.
How many interviews can I use?
Up to 10 sources and about 120,000 characters in one run, roughly two one-hour interviews or eight short sets of notes. Three to eight interviews is the sweet spot. One interview can only ever give "One participant" themes. If you go over, split it into two runs; we never cut text off silently.
Is my data stored or used to train AI?
Your text is sent to Anthropic, the company behind Claude, to produce the synthesis. Under Anthropic's commercial terms it isn't used to train their models. We don't store your transcripts or the result on our servers. In your browser they stay in this tab's session storage until you close the tab or press Reset.
Should I remove names?
Yes. Replace participants' names, employers, places and anything else that identifies them before you paste. We mask emails and phone numbers and swap speaker names for P1, P2 and so on, but we can't catch everything. Don't paste health, religion, ethnicity or other sensitive details unless your participants agreed to it.
What must I still check myself?
Read each Supported theme's quotes in context. Treat Interpretation and One participant themes as hypotheses. Check who you interviewed and who is missing, scan what the AI left out for anything that contradicts a theme, and don't present counts as percentages of users.
Can I turn the themes into a persona?
Yes. Tick the themes you want and open the persona builder with them filled in: pain points, goals and behaviours from the theme titles, and a few of your participants' own words as quotes. Nothing is invented, so you add the name and role. You can also send themes to a card sort as cards.
Is it free?
Yes, with no account. There is a daily limit on runs so that it stays free for everyone.
