Tigmi vs. Interior AI
Last reviewed: May 4, 2026 • 5 min read
A pioneering AI room redesign tool from indie hackers Pieter Levels and team.
Interior AI launched in 2022 as one of the first widely-known AI room redesign tools. It pulls reliable traffic and has been the on-ramp for a lot of people first encountering AI interior design. The product is intentionally simple: upload a photo, pick a style, get a redesign. That simplicity is its strength and its limit.
Tigmi entered later with the benefit of seeing what the simple version did well and where it ran out. We invested in a richer style library, finer-grained controls (Room Lock, palette extraction, inpainting), and language coverage so the tool fits both casual experimentation and real client work. Where Interior AI is a single-purpose generator, Tigmi is built as a workflow you return to across a project.
Neither is wrong for a different user. If you want to try AI room redesign once and decide whether the technology is good enough, Interior AI does that quickly. If you're going to use it more than a few times — for a real renovation, for client work, or for listing photos — the depth difference starts to matter.
Feature comparison
| Feature | Tigmi | Interior AI |
|---|---|---|
| Style presets | 50+ named styles | ~30 named styles |
| Room Lock (geometry) | Yes, granular control | Basic |
| Inpainting (swap elements) | Yes | No |
| Palette extraction | Yes | No |
| Free tier | Full quality, limited renders | Watermarked free tier |
| Language coverage | EN, FR, ES, DE, AR | EN-primary |
| Virtual staging | Yes, dedicated workflow | Redesign combination |
| Render speed | 20-40 seconds | 20-60 seconds |
Choose Tigmi when
- You need consistency across multiple renders for a client project.
- You want fine control over what stays and changes (Room Lock).
- You need watermark-free renders on the free tier.
- You want a fully localized non-English interface.
Choose Interior AI when
- You want the simplest possible tool to test once and walk away.
- You don't mind a watermark on the free output.
- You specifically want to try Pieter Levels' viral app.
Honest verdict
Interior AI deserves credit as a category pioneer — it normalized AI room redesign for a lot of people who'd never have tried otherwise. For one-off curiosity, it's still a fine choice and the simplicity is genuinely a feature.
Tigmi is the better fit if you'll use AI design more than a couple of times. The depth of the style library, the granular controls, the watermark-free free tier, and the multi-language support add up to a tool that scales from "try once" to "use weekly for client work".
Comparison FAQ
Is Tigmi based on the same technology as Interior AI?
Both are built on Stable Diffusion derivatives. The differences are in the fine-tuning, prompt engineering, and control layers, which determine the final output quality.
Can I export Tigmi renders for client presentations?
Yes — paid tiers export at full resolution without watermarks, suitable for printed presentations and listing proposals.
What about photorealism — does either tool do it better?
Both produce convincingly photoreal residential interiors, though edge cases like mirrors or complex moldings can trip both. Try a side-by-side test with your own photo to see the difference.
