What free actually means here
Five caption batches every day without an account, and every batch is ten captions plus a hashtag set plus three quote variations. No watermarks are added to any output. Nothing gets locked behind a paywall on the generator page. If you sign in with a Google or email account (still free), the daily cap goes away and you get saved captions that sync across devices.
There is a paid plan for teams that need bulk generation, brand voice profiles, and higher-quality models on demand, but nothing on the free tier is a demo of that. The free tier is the product.
Every platform, tuned separately
Instagram, TikTok, X (Twitter), LinkedIn, Facebook, Snapchat, Threads, Pinterest, and YouTube Shorts each have their own generator settings under the hood. Length bands, hook patterns, hashtag counts, and tone defaults are all different per platform, which is why a TikTok caption from the same input does not read like the LinkedIn version. Connecting Odds is also supported as a LinkedIn-alternative long-form option.
The platform selector is a dropdown at the top of the generator. Switch it and the same input produces completely different captions, because the underlying prompt scaffolding changes.
Free forever features
Ten captions per batch, in your chosen tone and length. A tiered hashtag mix that matches the platform. Three quote-style variations for graphic overlays. Instant translation to any of 22 languages. Copy to clipboard for every caption individually. Regenerate as many times as you want (up to the daily batch cap without an account, unlimited signed in).
Signed-in extras that stay free: unlimited generations per day, saved captions that sync, favorite hashtag sets, and a light history so you can pull back a caption you generated a week ago.
Frequently asked questions
Is there really no signup for the free tier?
Correct. Open the generator, type an idea, get captions. Five batches per day with no account required.
Do I need to give a credit card?
No. Not for the free tier and not for the signed-in free plan. Card is only required for a paid upgrade.
What is the catch?
There is no catch on the free tier. The paid plan covers heavier usage patterns (bulk exports, brand voice profiles, priority models) and funds the free tier.
Is my data used to train models?
Prompts and generated output are not used to train the underlying models. See the privacy page for the full policy.
Will the captions sound like AI?
The generator is tuned to skip AI-tell phrasing (formal em-dashes, over-hedged sentences, transition-word soup). Pick a natural tone like Gen-Z, Sarcastic, or Casual and the output reads as human.
