Build an AI video SaaS in eight days without coding experience using ChatGPT planning and OpenAI Codex
A non-programmer describes planning with ChatGPT and building a video generation site with Codex in eight days, including repeated rework, tool slowness and a quota that ran out.
Evidence: The author reports this. We have not checked it beyond reading the source.
The business problem
A non-programmer wants to launch a software product without hiring a developer.
What was tried
The author planned in ChatGPT, wrote specific expected results, implemented with Codex in a Windows environment, and reviewed the live site. The homepage was rebuilt repeatedly over the eight days, mostly because instructions were vague. The Codex command-line tool responded in seconds while the editor extension took minutes, and a $100 a month plan's weekly allowance ran out in about four days of heavy use.
What was reported (mixed)
The site launched, and the author says it has not achieved major results yet. No users, revenue or traffic figures are given.
Limitations
One person's experience with no comparison against other tools. The stack, hosting, pricing and time per day are not stated, the sample instruction is illustrative, and the page does not show a year. The author cannot always diagnose generated code that breaks.
What you need
A ChatGPT account and an OpenAI Codex plan (the author pays $100 a month), plus a domain and hosting. Other costs are not stated.
