Your profiles, your models
Pick a default profile per app, or bring your own API key on the Lifetime plan.
Free here: unlimited, this utility runs entirely in your browser. In the app: from $9/mo, or Lifetime from $69 with your own API key.
Deduplication is only trustworthy when its comparison rules are visible. Case-sensitive mode keeps differently capitalized lines distinct, while trimming determines whether surrounding spaces affect matching and output. Keeping the last occurrence preserves the original order of those surviving last entries rather than sorting the list. Counts for input, output, and removed duplicates update with every option, and all processing is local and unlimited.
