Postela

Postela is a small marketing studio for people who make things: a product, a shop, an app.

Make a post from a photo
Add up to five photos, type a name and a sentence about what you sell, and choose a format. Postela lays it out and gives you a finished image at the size the platform expects: Instagram post (1080 × 1080), Instagram story (1080 × 1920), Facebook post (1200 × 628), an A4 flyer or a 16:9 presentation slide. Each format comes in three styles: Bold, Minimal and Vibrant. Save the image to your gallery or share it to another app.

Copy, written for you
Connect your own Groq, Claude or OpenAI key and Postela writes three headlines, three captions, three hashtag sets and a call to action for every post, so you can pick the ones that sound like you. Without a key, Postela uses your own tagline and description.

Store screenshots for your app
Building an app? Place your screens in a device frame, add a headline, and style each slide. There are 12 device frames covering phones and tablets, 22 backgrounds, solid colours or your own photo, and a flat or 3D-tilted device. Frame colour, layout, text size and position can be set for each slide, with up to 8 slides in a set. Export the whole set at the sizes the stores ask for, including phone, 7-inch tablet and 10-inch tablet sizes and the feature graphic.

Your work stays with you
Photos are used on your device to build the layout and are not uploaded. API keys are kept in the Android Keystore and are sent only to the provider you chose.

Postela Pro
Images exported from Postela carry a small "Made with Postela" badge. Postela Pro is an optional subscription that removes it.
