Who buys this
Product and research teams drowning in open-text answers they never read.
Where to start in Lovable
Paste this into Lovable as the opening prompt. It sets up one screen and one job, which is easier to grow from.
Build a survey feedback analyser. Users paste a CSV of open-text responses or connect a Google Sheet. The app clusters answers into themes, labels each cluster, scores sentiment per cluster, and shows counts. One screen: upload on the left, clusters as cards on the right, click a cluster to see the raw quotes inside it. Add CSV export of the labelled data.
What you will need to wire up

Build order
- Parse before you cluster. Get CSV upload and column mapping working first. Users have messy exports with merged headers and empty rows. If parsing is unreliable the clustering never gets a chance.
- Cluster in batches. Send responses to the model in batches of about fifty with a fixed list of candidate themes, then merge. Asking one call to handle two thousand answers produces vague labels and costs more.
- Show the raw quotes. Every cluster must open into the actual sentences behind it. Without that, nobody trusts the summary, and trust is the whole product.
- Charge on volume. Rows analysed is the natural meter: it matches your cost and the customer understands it without explanation.
Where this usually breaks
- Cluster labels drift between runs on the same data, which makes the tool look broken. Pin the theme list after the first pass and reuse it.
- Long uploads time out on the default request limits. Process in a background job and poll for status.
How it makes money
- Per row analysed. Simple to explain, tracks your model spend almost exactly.
- Monthly seat with a row cap. Better retention, but you carry the overage risk.
