Every option in the catalog for when you need to generate game assets and living NPC characters — 5 AI game development tools, 5 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 5 of them, ordered free tiers first: Convai, Inworld AI, Rosebud AI, Scenario and Summer Engine. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
None of these are marked fully free — they are freemium, trial or paid. The Completely Free AI Tools collection lists the 396 entries in the catalog that carry no paid plan at all.
See the full list →Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
Convai, Inworld AI, Rosebud AI and Scenario all work in a browser tab with no install needed — just open the site and go. 4 of the 5 free AI game development tools listed here are browser-based.
Inworld AI and Summer Engine support Google sign-in, so you can start without creating a new account. That's 2 of the 5 free AI game development tools on this page.
Summer Engine can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 1 of the 5 free AI game development tools here run offline.
