NOT REALLY
why this verdict
Keep paying — OpenAI has not replaced it
OpenAI's version overlaps, but does not finish the design job, so this one still earns its $15/mo.
- A named launch, not a vibe named, unlinked
- AI generates UI, but not evidence of what real apps do. OpenAI, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 2 of 2 listed replacements have a usable free tier: Refero and Land-book.
- What the call is worth $180/yr
- $15/mo at the entry paid tier — $180 a year per seat.

The backstory
Mobbin is a research archive: hundreds of thousands of screenshots from shipping apps, tagged by flow and pattern. Models invent plausible interfaces; Mobbin shows what Airbnb actually does at step three of onboarding, and that evidence is a curated asset nobody can hallucinate.
