AI interior design apps with no signup (tested)
RoomsGPT let us generate with no login in both of our tests. HomeDesignsAI was no-login in our first test but now requires login (email, Google or Facebook). Paintit and MeltFlex advertise no signup but required an email; AiHouse required Google or Facebook login; DecorAI required starting a card trial.
Based on our hands-on test on Oct 16, 2026: Empty white room (right-wall window, concrete floor, left-wall outlet), prompt "Living Room + Scandinavian". Tools change often; see full test results and warnings.

Tools we could not test
- Collov AI: Could not test: signup bug. Email verification accepts the code but never creates the account (tried twice on Oct 16, 2026).
- AiHouse: Not tested: requires Google/Facebook login.
- DecorAI: Could not test without a card: the site advertises '3 Free Designs', but Generate opens a trial that becomes $24/month (plans $24/mo, $120/6 months, $240/year). We stopped before entering a card; there was no free generation without starting a trial (Oct 16, 2026).
