Instagram posts that actually sound like you
Stop staring at a blank screen. Posty learns your voice from the posts you have already published, then hands you ideas and finished captions built for your brand.
Free to download. Works before you connect Instagram — connecting is what makes it sound like you.
Three taps from blank screen to posted
Pick an idea. Tap generate. Post.
-
1
Sign in and connect Instagram
Sign in with Apple and you can start straight away. Connecting your Instagram profile lets Posty read your existing posts, learn how you write, and draft a short brief about your business for you to check — the difference between generic suggestions and ones that sound like your account.
-
2
Pick an idea, or type your own
Posty puts a mix of tailored post ideas on the home screen — something useful, behind the scenes, what's new. Choose one and it becomes a full caption with hashtags. If you already know what you want to say, type it in and Posty writes it up in your voice.
-
3
Adjust it, then post it yourself
Make it shorter, longer, funnier, more personal or more businesslike in a tap. Add a photo or generate an image. When you are happy, share it to Instagram — that last step is always yours. Not ready yet? It waits in your drafts.
What you get
-
It learns your voice
Posty reads the posts already on your profile — your tone, your subjects, the way you actually write — and generates ideas that match. Not generic AI filler that could belong to anyone.
-
It knows what is going on this month
Posty drafts a short brief about your business from your own posts: what you do and who it is for. You correct it, add what is true right now — an offer, a new menu, changed hours — and every caption uses it.
-
A mix of ideas, waiting when you open it
Suggestions sit on the home screen, each labelled with the kind of post it is: something useful, behind the scenes, what's new, proof or personal. The next set leans towards the kinds you have not posted lately.
-
Full captions, not prompts
Every idea expands into a publish-ready caption with hashtags. Use it as it is, or tune it in a tap: shorter, longer, funnier, more personal, more businesslike.
-
Reminders that bring the post with them
Pick your days and a time. Turn on "Arrive with a post ready" and the caption is already written when the notification comes — tap it, add a photo, share. A reminder still never posts anything.
-
Nothing you generate is lost
Every post is saved as a draft on your phone as you work on it, photos included. Leave halfway and it waits on the home screen until you share it, mark it posted or delete it.
Posting reminders
The reminder brings the post with it
Knowing you should post more is not the problem. Starting a post on a Tuesday, in the middle of a working day, is. So Posty can write the caption before it reminds you, and the notification asks you to approve a post rather than make one.
- Pick your days and one time — three a week is plenty to start.
- Turn on "Arrive with a post ready" and tapping the notification opens a finished caption. Add a photo and share it.
- Each ready post uses one from your weekly allowance, so it is off until you switch it on. Without it, the reminder opens Posty with ideas waiting.
- It is a notification and nothing more. Posty never publishes for you, reminder or not.
Your Posty impact
Is your profile looking alive?
Someone checking you out before they call does not look at your likes. They look at when you last posted. Posty shows you that first, then whether the posts are landing, so you can stop guessing on both counts.
- Showing up: weeks posting in a row, your last post, your best run and your longest quiet stretch.
- Every synced post with its likes and comments, with the ones Posty helped write marked.
- Recent posts are flagged as still settling rather than counted early, because two-day-old numbers are not results yet.
- Once there are enough posts on both sides, Posty compares the two and shows you the difference.
Built for people with a business to run
Posty is shaped around the accounts that need to post regularly and have no time to plan it.
-
Instagram caption ideas
Most caption generators hand you something technically correct and completely anonymous. The problem was never grammar — it was that the words did not sound like your account.
-
Post ideas for small business
You know you should post more. You also have a business to run, and content planning is the thing that quietly slides to next week, every week.
-
AI caption generator
Most AI caption tools begin with an empty prompt box and no idea who you are. Posty begins with the account you have already built.
-
What to post
The blank screen is rarely a writing problem. It is a deciding problem — you would happily write the caption if you knew what the post was about.
-
Restaurants and cafés
The food is the easy part to photograph. Saying something about it that is not 'come and try our new dish' is where most café accounts stall.
-
Boutiques and shops
Stock moves faster than content plans. A piece arrives, sells out, and never gets posted — because writing about it was a separate job nobody had time for.
-
Coaches and creators
Your voice is the product. Which is exactly why generic AI captions are useless to you — an anonymous post costs more than no post at all.
-
Salons and studios
Your work is visual, so the photos are never the problem. The caption underneath is what keeps not getting written.
-
Real estate agents
Listing photos are handled. What is missing is a caption that sounds like a person rather than a portal description with emojis added.
Questions people ask first
What is Posty?
Posty is an AI-powered content companion for Instagram. It learns your voice from the posts you have already published, then suggests fresh post ideas and writes full captions in your style. Posty creates ideas and captions only — you decide what gets published, and you post it yourself.
Does Posty automatically post to social media for me?
No. Posty does not publish or post anything to your social media accounts. It only generates post ideas, captions and images. You copy the content and post it yourself, to whichever platform you choose, whenever you choose.
How does the AI content generation work?
Posty reads the posts already on your connected Instagram profile to learn your tone, your subjects and your audience, and pairs that with a short brief about your business that you confirm. It then generates ideas that fit that voice rather than generic AI filler. Every suggestion is editable — you can make a caption shorter, longer, funnier, more personal or more businesslike before you use it. Once you are happy with an idea, you copy it and post it manually.
Why does Posty ask about my business?
Your posts show how you write, but not what is true this month. When you connect Instagram, Posty reads your captions and drafts a short brief — what you do and who it is for — then asks you to correct it and add what is going on right now, like an offer, a new menu or changed hours. Every suggestion and caption uses it. You can skip the step, and edit the brief later from Your business on the About screen.
Do I need to connect my Instagram account?
Not to get started. You can sign in and use Posty to generate ideas and captions before connecting anything. Connecting Instagram is what lets Posty learn your particular voice from your past posts, so the suggestions stop being generic and start sounding like you.
Can Posty make the images too?
Yes. You can attach photos from your gallery, take one with the camera, or have Posty generate an image from a description. Generated images follow the style you pick, so they sit alongside the caption rather than looking bolted on.
Can I see whether I am posting enough, and whether it is working?
Yes. Posty shows how consistently you are showing up — how many weeks in a row you have posted, when your last post went up, your best run and your longest quiet stretch. Below that it lists the posts you publish with their likes and comments, marking which ones it helped you write. Once you have enough posts of each kind, it compares the two and shows you the difference. Until then it shows the plain numbers rather than a percentage, because a percentage from two or three posts is noise rather than a result.
