How to use it

  1. Say what the post is about

    Write it the way you would tell a customer. One real detail — a date, a price, a new item — is what separates a caption you can use from one you cannot.

  2. Pick the platform, the tone, and who is reading

    Instagram, Facebook, or LinkedIn. Friendly, professional, or playful. Then say who you are talking to, like “neighbors” or “office managers”.

  3. Copy the one you like

    Change anything that does not sound like you, check the facts, and post it with your photo or video.

How long a caption can be

Every caption from this tool is at most 280 characters, so it fits everywhere. The number that decides whether anyone reads it is the last one: a phone shows the first line or two and hides the rest.

Instagram

2,200

Characters allowed in one post.

Not published by Meta. This is the figure caption counters have used for years.

Facebook

63,206

Characters allowed in one post.

Not published by Meta either, and far past what anyone reads in a feed.

LinkedIn

3,000

Characters allowed in one post.

LinkedIn Help, read September 5, 2026.

Before “… more”

about 125

What shows on a phone before the rest is hidden.

Nobody publishes this one. The app shows a couple of lines, so it moves with the phone, the app version and your own line breaks.

Want the first line to do more work? The hook generator writes opening lines for one post, each one on a different angle.

Common questions

What should I write in the post description?

Say what you want to share and add one or two real details: a date, a price, a name, an invitation. “Rosemary sourdough is back Saturday, doors open at 8 am” gives you three captions you can use. “We do quality baking” gives you three you cannot. Only put in offers, dates, and claims that are true — the captions are written from your words and nothing else.

Does picking Instagram, Facebook, or LinkedIn change the caption?

It is passed to the model as the platform to write for, along with the tone you chose, so the wording comes back to suit it. It does not change the length: every caption from this tool is at most 280 characters, whichever platform you pick.

How long are the captions, and will they fit?

Three options, each at most 280 characters. That is this tool’s own ceiling. Instagram allows 2,200 characters, LinkedIn 3,000 and Facebook far more, so a caption from here always fits. What matters more is the start: a phone shows about 125 characters and hides the rest behind “… more”, so the first sentence has to carry the post.

The captions came back generic. What now?

That is almost always the description. Replace anything general with one specific thing that happened this week — the item, the day, the number, the question a customer asked — and generate again. Naming who you are talking to helps too: “neighbors” and “office managers” produce different captions.

Can I edit the captions before I post?

Yes, and you should. Copy one, change the words so they sound like you, and check every detail against what is true. AI can make mistakes, and a draft may resemble other writing. Nothing is posted for you.

What can’t it do?

It does not research hashtags, predict how a post will do, write your picture or video, read your website or your past posts, or connect to your social accounts. It writes three short captions from the words you type, and that is all it sees.

Is it free, and what happens to what I type?

It is free and needs no account or card. There is a daily limit across our free tools so they stay available; if you reach it the tool says so. What you type is sent to Soyla’s generation service and its AI provider to write the captions, and the result stays available to the same browser session for 15 minutes. Leave out private customer details. See Soyla’s privacy policy for more.
