Tigmi vs. RoomGPT
Last reviewed: May 4, 2026 • 4 min read
A free AI room redesign tool that became one of the most-shared open-source AI demos.
RoomGPT got famous for being free, fast, and open source. Hassan El Mghari built it as a Replicate demo and it spread organically — many people's first exposure to AI redesign was through RoomGPT. As a demo, it's excellent.
As a daily-use tool, it has limits. The style library is small. There's no inpainting, no palette extraction, no Room Lock. Output resolution is fixed. Ongoing maintenance has slowed since the original viral period. None of that is criticism — it was built to demonstrate what was possible, not to be a sustained product.
Tigmi sits where RoomGPT pointed. We took the consumer accessibility seriously (free tier, no signup required to start) and built a fuller product behind it: more styles, more controls, multi-language UI, dedicated virtual staging, designer/realtor tiers.

Honest verdict
RoomGPT did something important: it made AI room redesign viral. A lot of people in this space owe their start to that demo, and we're not embarrassed to say Tigmi exists partly because RoomGPT showed the demand was there.
For real day-to-day use, the gap is wide. RoomGPT is a 7-style restyle tool; Tigmi is a redesign workflow. If you only need what RoomGPT does, by all means use it — it's free and works. If you need anything past that, the upgrade path is real.
Comparison FAQ
Is RoomGPT still being updated?
The repo is intermittently maintained but ships infrequently. Treat it as a stable demo rather than an evolving product. Tigmi ships weekly.
Why does Tigmi cost money when RoomGPT is free?
RoomGPT runs on Replicate's infrastructure with limited usage; Tigmi has its own GPU pool, ongoing R&D, support, and feature development. The free tier is genuinely free; the paid tiers fund what comes next.
