The useful minimum
Built for one-off batches
You should not need an enterprise platform, a monthly plan, or a weekend of glue code to classify a spreadsheet once.
Choice
Select one value from categories you define, with per-option probabilities and confidence.
Predicate
Estimate the probability that a clearly written condition is true for each row.
Score
Rate each row across ordered rubric levels and keep the returned distribution.
Local-first file handling
Your full CSV is parsed in the browser. Only the selected cell values are relayed to OpenAI.
