What is Lemma?
Lemma helps teams run adaptive studies and turn responses into evidence, Doc, Slides, and decisions.
Lemma is an AI interview and study platform.
Use it when a static form would collect the first answer, but your team needs the reason, example, objection, tradeoff, or quote behind that answer.
The app model
The container you create in Lemma. A study defines the goal, interaction format, follow-up depth, and questions.
A completed participant interview or conversation inside a study.
The table where you review sessions, summaries, transcripts, and answers.
The generated Doc, Slides, and Research Agent answers that synthesize the study data.
When to use Lemma
Lemma is strongest when the useful answer appears after a follow-up.
Common workflows:
- customer discovery
- customer satisfaction
- product/service feedback
- churn and cancellation follow-up
- lead qualification
- employee experience
- message testing
- client or stakeholder discovery
How Lemma differs from static forms
Static forms are good for structured fields and operational collection.
Lemma is better when you need:
- a conversation instead of a single text box
- follow-up questions
- transcripts and summaries
- themes and quotes
- Doc and Slides outputs
- a Research Agent that can answer questions about the study data
What Lemma is not trying to replace first
Use a standard form builder when you primarily need:
- a simple signup form
- payment collection
- file upload
- quiz scoring
- exact branching-logic parity
- heavily branded embedded website forms
