Promo video generator for app founders
StartKitz is a promo video generator for SaaS and mobile apps. Paste your app URL and it generates video scripts and renders vertical MP4 promo videos — ready for TikTok, Instagram Reels, and YouTube Shorts.
What it does
StartKitz reads your product's landing page and generates a promotional video script grounded in your product's actual features and positioning. On Creator and Launch plans, it also renders the script into a finished vertical MP4 video file — 1080x1920, 12-15 seconds, with bold text overlays and your app name and URL. The video is ready to upload to TikTok, Instagram Reels, or YouTube Shorts without any editing.
Who it's for
StartKitz is built for SaaS founders, indie hackers, and app developers who need short-form video content for launch and ongoing promotion but don't have video production skills or tools. It is particularly useful for founders launching on TikTok, Instagram Reels, or YouTube Shorts who need professional-looking video assets quickly, without hiring a designer or learning video editing software.
What it generates
StartKitz generates 3 video scripts in different formats: pain_solution (leading with the problem your product solves), feature_spotlight (highlighting a key feature), and founder_launch (a founder's perspective on why they built the product). On Creator and Launch plans, all scripts are rendered into finished MP4 files — vertical format, 1080x1920, with animated text overlays, colored backgrounds, and your app name and URL. Scripts are included with the Starter plan for founders who want to record their own videos.
How it compares to hiring a video editor
Video editors typically charge $200-500 per short-form video and require a brief, a script, and review rounds. StartKitz generates the script and renders the video in under 2 minutes from your app URL — no brief, no back-and-forth. The output is a clean, simple slide-style video optimized for TikTok and Reels rather than a cinematic production. For founders who need a starting point quickly, it is the fastest path to a finished video asset.

What is an app promo video generator?
An app promo video generator is a tool that creates promotional videos for your software product automatically — including the script and the rendered video file — without requiring video editing skills or design software. You provide your product information and receive a video file ready to post.
What video format does StartKitz produce?
StartKitz renders vertical MP4 video files at 1080x1920 resolution — the standard format for TikTok, Instagram Reels, and YouTube Shorts. Videos use bold text overlays with your app name and URL, run 12-15 seconds each, and are designed to be fast-loading and clean rather than cinematic.
Do I need video editing skills?
No. StartKitz generates both the video script and the rendered MP4 file from your product URL. You receive a finished video file ready to upload directly to TikTok, Reels, or Shorts. If you want to edit further, you can use the MP4 as a starting point in any video editor.
How long are the videos?
Each video is 12-15 seconds — the optimal length for short-form content on TikTok, Instagram Reels, and YouTube Shorts. Videos are rendered once at purchase and are not re-rendered on regeneration.
What plans include video generation?
The Creator plan ($39) includes 1 rendered promo video. The Launch plan ($99) includes 3 rendered promo videos. The Starter plan ($19) includes video scripts but does not include rendered MP4 files. All plans include video scripts you can use to record your own content.
