FAQ

Questions, answered.

Which platforms does the AI caption generator support?

+

Instagram, Facebook, TikTok, X (Twitter), LinkedIn, Threads, Pinterest and YouTube community posts. Each platform gets its own length, tone and hashtag style automatically.

How is this different from ChatGPT?

+

ChatGPT writes whatever you ask. Our generator is pre-prompted with platform-specific rules — character limits, hook structure, hashtag etiquette — and your audience context, so the first draft is usually publish-ready.

How many variations does it generate?

+

Up to 10 caption variations per request, including hook-led, value-led and CTA-led versions so you can A/B test in your scheduler.

Can I keep my brand voice consistent?

+

Yes. When you sign in, you can save a Persona — a profile of tone, vocabulary and example posts. Every caption you generate is filtered through that persona so the voice stays yours.

Will my captions be unique?

+

Captions are generated fresh per request using your inputs as the seed. We don't reuse outputs across users. If you want zero overlap, vary your inputs (tone, length, hook angle).

Can the captions auto-publish?

+

Yes. Send any generated caption straight to the Publot scheduler — or hand the whole post over to the autonomous agent and let it publish into the highest-engagement window automatically.
