About Demopost

Demopost turns a screen recording of your app or website into LinkedIn posts with cards, Reddit posts and reel scripts that only say what your screens show.

It is built and run by Nishant Pandey, a solo developer in Gurugram, India. It started as the marketing step for his own app, KinScan, a face-resemblance app for families: the screens were ready, the posts were not. The tool that wrote those posts from the screens became this product.

What it does

You upload a screen recording of your app, or give a URL of your website. Demopost cuts it into screens, describes each one from the frame, and writes a LinkedIn post with a 4:5 card for each screen, Reddit posts for the subreddits you choose, and reel scripts matched to your footage. You copy and post them yourself.

The rule it keeps

Every post names the screen it was written from, and claims only what that screen shows. No invented users, results or numbers. Reddit posts grow from context you write in your own words, and nothing is added about you that you did not say. Drafts that break the rule are dropped and the credits come back.

What it does not do

It does not post to your accounts and never asks for access to them. It does not generate presenters or fake customers. It does not keep your screens longer than you do: delete a product or your account and the files go with it.

Limits

screens are 3 to 15 seconds each, uploads up to 300 MB, website recordings 12 to 30 seconds, one recording or upload at a time per account, at most 150 credits spent per day, output in English.

Where it runs

On a single rented server in Helsinki, Finland. Writing uses Anthropic's Claude API. Sign-in emails go through Resend. Payments and invoices are handled by Dodo Payments as merchant of record, so card details never touch this site. Details are on the privacy page.
