Which tool do I need?
Start with the formatter if your tags are messy, and with the counter if your caption is already written.
- Tags copied from notes, a spreadsheet or an old post: Hashtag Formatter & Cleaner.
- A finished caption you want to check against a platform's limits: Hashtag Counter.
- The same tags every week for a series or a brand: Hashtag Set Builder.
- Choosing a new branded or event tag: Hashtag Readability Checker.
Hashtagr does not generate "trending" tags or estimate reach. It has no access to platform data, and numbers like that from any outside tool are guesses. Check a tag in the platform's own search before you rely on it.
