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 is what lets Posty read your existing posts and learn how you write — the difference between generic suggestions and ones that sound like your account.
-
2
Pick an idea, or type your own
Posty puts a set of tailored post ideas on the home screen. 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.
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.
-
Ideas waiting when you open it
A fresh set of suggestions sits on the home screen, tailored to your brand. Pick one and it becomes a full caption. No blank screen, no brainstorming session.
-
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.
-
Your idea, written up
Already know what you want to say? Type it in and Posty writes it in your voice, so a half-formed thought becomes something worth publishing.
-
Images to go with it
Add photos from your gallery or camera, or generate one from a description in the style you choose — realistic, drawing, caricature, vintage and more.
-
Reminders that nudge, never post
Posty can remind you when it is a good moment to share something, so consistency does not depend on memory. A reminder is a notification and nothing more.
Posting reminders
The habit is the hard part
Knowing you should post more is not the problem. Remembering on a Tuesday, in the middle of a working day, is. Posty can nudge you on the days you choose, at a time you choose.
- Pick your days and one time — three a week is plenty to start.
- A reminder opens Posty with ideas already waiting, so there is no blank screen to face.
- It is a notification and nothing more. Posty never publishes for you, reminder or not.
Your Posty impact
Find out if any of it is working
Posting into the void is demoralising. Posty keeps track of what you publish and shows it back to you with the numbers attached, so you can see which posts landed instead of guessing.
- Every synced post with its likes and comments, newest first.
- Posts Posty helped write are marked, so you can tell them from the ones you wrote alone.
- 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, 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.
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 my posts are actually doing better?
Yes. Posty keeps track of the posts you publish and lists them 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.
