Free tools FAQ

About these tools.

Are these tools really free?

Yes. Every tool works without an account, and there’s no paywall on the results. We build them because people who care about their social presence are the people Postivate is for.

Do you store what I type?

No. Usernames and descriptions are only used to run the check or write the text, and aren’t saved.

Which tools use AI?

The writing tools (bios, captions, titles, hashtags and hooks) use the same AI that powers the assistant in Postivate. The rest, like the username checker, character counter, font generator and Post to Image, run on plain rules, and Post to Image never uploads your images.

What is Postivate?

Postivate is a social media management app for creators, brands and agencies: write once, tailor posts for Instagram, X, LinkedIn, Facebook, Threads, Bluesky, Telegram, Mastodon, Pinterest, TikTok and Tumblr, get them approved, schedule them and see what worked.
