ViralKit hands app and SaaS founders fresh short-form videos every day, ready to download and post before your coffee goes cold

There is a well-worn TikTok format for apps: a few seconds of someone reacting with shock or delight, then a screen recording of the product. ViralKit automates it. You tell it about your product, upload a demo, and each day it produces new hook-plus-demo videos using a library of AI reaction clips. No editing, no filming yourself.

For a solo founder who knows they should be posting daily and never does, that is an appealing deal. The format is proven enough that you will recognise it instantly, and removing the blank-page problem is most of the battle.

Where it shines

Consistency is the whole game on short-form video, and ViralKit is built to make consistency the default. Every day there are new pieces waiting, each one opening on a different reaction from a library of a few hundred AI clips, so your feed does not feel like the same video posted on repeat. Your demo footage does the selling, which keeps every post honest about what the product actually does.

It is also refreshingly quick to set up. Point it at your product URL or write a short description, add screenshots or a 9:16 demo, and the assembly is handled. The founder, who signs the changelog as DAZ, shipped version 1.0 on 13 September 2026 and has been pushing fixes since, so this is a product being actively worked on. The one-day trial is enough to see the format with your own product before you pick a plan.

Who it's for

Indie founders with an app or SaaS product and a TikTok account that deserves more love. If you have a demo video, ViralKit turns it into a steady posting habit across TikTok, Instagram, Facebook and YouTube.
