Usage / FAQ
When to use
- Paste any text when you're unsure which tool to reach for
- Quickly recognize unfamiliar tokens (e.g. from an Authorization header)
- Inspect what type of data an API response contains
- Tell apart CSV vs TSV and other near-identical formats
- Plan a multi-tool workflow by previewing matches side by side
FAQ
- Q.What if detection misclassifies?
- A.Only matches with confidence ≥ 0.5 appear. If your intended tool is missing, search directly via the header (`Cmd+K`).
- Q.Can multiple formats be detected at once?
- A.Yes — e.g. a Base64 string that decodes to JSON shows both tools. Results are ranked by confidence.
- Q.Is the text sent anywhere?
- A.No — every detection runs locally in the browser.
