For product makers

From product photo to scroll-stopping post.

Postela turns a photo and a few words into a finished Instagram post, story, flyer or slide. It also builds your App Store and Google Play screenshots. All on your phone.

Two tools, one app

Everything a launch needs to look finished

One tool for what you post, one for how your app looks in the store.

Marketing posts

A product photo in. A polished post out.

Add up to five photos, describe what you sell, choose a format and a style. Postela lays it out and hands you a file sized for where it is going.

Store screenshots

App Store and Google Play sets, without a designer.

Drop your app's screens into device frames, add a headline, pick a background, tilt the phone in 3D. Export every size the stores ask for.

How it works

Three steps to a post

Add your photos

Pick from your library or take one now. The first photo becomes the main image.

Say what it is

A name, a sentence or two, an optional tagline. Postela writes headlines, captions, hashtags and a call to action for you to choose from.

Pick a format and save

Five formats and three styles. Preview it, swap the copy, then save to Photos or share it straight out.

Choosing between Instagram Post, Instagram Story, Facebook Post, Flyer and Presentation

Formats

Five formats, each in Bold, Minimal or Vibrant.

Three headline options, three captions and hashtag sets to choose from

Copy

Three options for every line. Tap the one that sounds like you.

Styling a store screenshot with a tilted device and background controls

Screenshot style

Backgrounds, layout, frame colour, tilt and text size, per slide.

Export step with Save all buttons for each App Store size

Export

Save the whole set at each store size with one tap.

Sized for where it goes

Exact pixels, every time

Exports come out at the size the platform expects, so nothing is cropped or rejected.

The details

Your AI, your keys, your photos

Postela has no server of its own. What you make stays with you.

Bring your own AI

Connect Groq, Claude or OpenAI with your own API key and Postela writes your copy in seconds. Groq has a free tier.

Or write it yourself

No key, no problem. In Local mode your own tagline becomes the headline and your description the caption.

Keys stay on the device

API keys are kept in the iOS Keychain or Android Keystore and are sent only to the provider you chose.

Photos never upload

Your photos are used on the device to build the layout. Only the text you type is sent to an AI provider, and only if you use one.

3D device tilt

Flat, tilted left or tilted right, with a real perspective render and a soft shadow under the phone.

History

Your last 50 posts are kept on the device, so you can reopen one and export it again.

Free and Pro

Everything is free. Pro removes the badge.

There are no ads and nothing is locked. Free exports carry a small "Made with Postela" badge in the corner; Pro takes it off.
