You will see each part of the descriptor highlighted, the merchant we found, and the exact JSON the API returns.
The pipeline
- 1 Cache Seen this exact descriptor before? Answer from memory or the database.
- 2 Rules Exact, prefix and regex patterns for known merchants.
- 3 Fuzzy Trigram match against merchant names, for typos and truncation.
- 4 AI Only for descriptors never seen before. The answer is cached and reviewed.
Your tries are kept in this browser only. Anonymous tries share a small daily AI budget; descriptors already in our database always work.
