How to use it
Say what the post is about
One real thing beats a summary of your business: a question a customer asked, what went wrong on a job, a number from your own week. That detail is what the hooks are built out of.
Choose spoken or written
A spoken hook is at most 70 characters, about three seconds of talking. A written one is at most 125, so it lands before a phone hides the rest of your caption.
Pick an angle and make it yours
Every line is labelled with the angle it uses. Copy the one that fits, change the words so they sound like you, and check the facts before you post.
Examples
Three businesses, what they typed, and two of the five hooks they got back.
A heating and cooling company
Spoken · Reel, TikTok, or Short
They typedA customer’s upstairs ran 8 degrees hotter than the downstairs all summer. The return vent had been painted shut by the previous owner.
They got
The common mistake
Your upstairs is not hot because the AC is too small.
A real number
This upstairs ran 8 degrees hotter than the downstairs.
Both fit in three seconds, and neither needs the picture to make sense.
Every run picks 5 of these 7 and never repeats one. The label above each line tells you what it is doing, so you can write the next one yourself.
The question they already ask
Opens with something a customer types into Google or asks at the counter.
The common mistake
Names what people usually get wrong, so the rest of the post is worth reading.
A real number
Leads with a figure you gave us. A specific number stops people; a general claim doesn’t.
Behind the scenes
Shows the part of the job a customer never gets to see.
Who it’s for
Says out loud who should keep reading, so the right person stops.
The myth
Corrects something people believe about your work that isn’t true.
A moment from the job
Starts in the middle of one real thing that happened.
Where a post gets cut off
A feed shows a line or two of your caption and hides the rest behind “… more”. A video gets about three seconds before somebody scrolls. Those two cuts are why a spoken hook and a written hook are not the same sentence.
Instagram
about 125 characters
Roughly two lines, then “… more”. A Reel caption is cut shorter.
Facebook on a phone
about 125 characters
Three or four lines, then “See more”. A desktop shows far more.
LinkedIn in the app
about 140 characters
Nearer 210 on a desktop, and a blank line costs you one of them.
A Reel, TikTok, or Short
about 3 seconds
Six to twelve spoken words before somebody decides to stay.
None of these are published limits. The apps cut by how many lines fit on the screen, so the number moves with the phone, the app version and your own line breaks. Written hooks are sized to 125 characters, the tightest caption cut of the three, so a line that fits Instagram fits the other two.
Common questions
What should I type in the box about my post?+
One real thing, the way you would tell a customer. A question somebody actually asked, what went wrong on a job, a number from your own week. “We do quality work” gives you five forgettable lines; “her upstairs ran 8 degrees hotter because a vent was painted shut” gives you five you can use. The hooks are built out of that sentence and nothing else.
What is the difference between the spoken and the written option?+
A line you say out loud in the first three seconds of a Reel is not the same sentence as the first line of a written caption. Spoken hooks come back shorter and plainer — six to twelve words, no semicolons or brackets, nothing that only works on paper. Written hooks are built to land the interesting part before the feed hides the rest of your caption behind “… more”.
How long is a hook, and why that long?+
A spoken hook is at most 70 characters, which is about three seconds of talking. A written one is at most 125, which is roughly where Instagram and the Facebook mobile feed stop showing a caption. Neither is a published limit: they are layout cuts that move with the phone, the app version and your own line breaks, so 125 is the tightest of them and a line that fits it fits LinkedIn too.
Do I have to use the angle it gives me?+
No. The angle is named so you can see why the line works and write the next one yourself. Copy the one that fits, change the words so they sound like you, and check every detail before you post. AI can make mistakes, and a draft may resemble other writing.
The hooks came back flat. What now?+
That is almost always the description. Swap anything general for one specific thing from this week — the figure, the question, the thing that went wrong — and generate again. Saying who it is for helps too: “homeowners with a two-story house” produces different lines than “everyone”.
What can’t it do?+
It writes five opening lines and nothing else: no caption, no script, no hashtags, no picture. It cannot tell you how a post will do, it does not know your account or your past posts, and it does not post anything for you. It only sees the words you type.
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 hooks, and the result stays available to the same browser session for 15 minutes. Leave out private customer information. See Soyla’s privacy policy for more.
