Every AI 3D tool ranked by performance and value — from Play Store apps to web-only powerhouses. Credits, pricing, and real output quality, all in one place.
AI 3D generation exploded in 2025–2026. You can now go from a single photo or text prompt to a fully textured, export-ready 3D model in under 30 seconds — on your phone. But not all tools are equal. Credit costs, generation quality, free tier generosity, and platform availability vary wildly between apps.
This guide covers every major tool across two categories: Android Play Store apps (mobile-first) and web-only platforms (browser or self-hosted). Each is ranked by a composite score weighing output quality, value for money, free tier generosity, and ease of use. We also document the exact credit economics so you can compare apples to apples.
Note: KIRI Engine, MagiScan, LucidPix, and Motionleap are photogrammetry or parallax tools — they reconstruct real objects rather than generating from imagination. They are included but ranked separately in context.

The most generous free tier of any mobile AI 3D app. Tripo generates clean, game-ready topology in ~10 seconds using text or image input. Smart Mesh P1.0 (March 2026) solved the chaotic mesh problem — assets come out production-usable without Blender cleanup. Includes auto-rigging, animation, and style filters (voxel, clay, LEGO). At 150 free credits + 50 signup bonus at 10 credits/gen, you get ~20 models free monthly — the best value in mobile AI 3D by a wide margin.
KIRI is the gold standard for mobile photogrammetry — walk around a real object with your phone camera, and it reconstructs a detailed 3D mesh. Completely free with unlimited scans and unlimited exports (no credit system at all). Rated 4.15/5 with 6,400+ reviews. The Pro tier ($6.99/mo) adds Quad Mesh, 8K PBR textures, and Gaussian Splatting. Different use case from generative AI — for scanning real-world objects, nothing on Android beats it.
Meshy is the most established AI 3D platform with 10M+ creators globally and 40M+ models generated. The Play Store app gives access to Meshy 6 — their best model yet with sculpting-level detail. Key advantage over Tripo: native Blender and Unity plugins for direct in-editor generation. The free tier is tight (100 cr/mo + 20 email bonus at 30 cr/gen = ~4 models/mo), but the quality per generation is excellent. Best for creators already in a Blender/Unity workflow.
MagiScan (marketed as TextTo3D on Play Store) is beginner-friendly with a clean 360° walk-around mode and strong integration with NVIDIA Omniverse and Minecraft. Free tier is very limited (2 scans/mo, +10 with subscribe & repost). The main complaint: free queue wait times can stretch to 2 days. If you can live with that, the output quality is solid. Paid at $7.99/mo is one of the cheapest unlimited options.
Not a true 3D model generator — LucidPix creates parallax depth effects from 2D photos using AI-generated depth maps. Unlimited free usage (with watermark), Pro removes watermark for ~$3/mo. Great for reviving old photos and social media content, but doesn't output usable 3D mesh files. Ranked last in this category because it doesn't compete with the others on actual 3D model output.
Microsoft Research's TRELLIS 2 (CVPR 2025 Spotlight) is the quality king of AI 3D generation — and it's free. Generates in ~3 seconds with textures up to 4096×4096, operating entirely in 3D space using O-Voxel representation. Available free at trellis2.app with no account required, or self-hostable on a CUDA GPU for unlimited local generation. Main limitation: image-to-3D only (no text-to-3D), no rigging, and output meshes tend to be high-poly requiring cleanup for game pipelines.
Rodin (by Hyper3D/DeemosTech) uses a 10-billion parameter model to produce the highest-quality photorealistic 3D meshes available outside enterprise tools. The unique pricing model lets you generate completely free — you only pay $0.50–$1.50 when downloading a result you're satisfied with. This means you can iterate endlessly without burning credits. 4K PBR textures, clean quad topology, and multiple export formats. Best for when output quality is the top priority.
Tencent's Hunyuan3D rivals proprietary tools in output quality and is completely free and open source. Self-hostable on a capable CUDA GPU for unlimited generation. Hunyuan3D 3.5 (2026) adds 8K PBR textures and sub-60 second generation. Available online too via platforms like Hugging Face. Best for developers who want full control and zero ongoing costs. Requires technical setup — not plug-and-play for beginners.
3D AI Studio doesn't build its own AI — it aggregates all the major ones (Meshy, Tripo, Rodin, Hunyuan, TRELLIS) under one dashboard. At $14/mo for 1,000 credits (~20 cr/gen), you get 5× more models than Tripo's paid tier at a lower price. You can try different AI engines on the same prompt and pick the best result. No free tier beyond trial credits, and it's web-only — but the value proposition for heavy users is hard to beat.
Sloyd takes a different approach — parametric template-based generation with sliders rather than pure AI generation from scratch. This makes it extremely predictable and print-ready out of the box. Free starter tier available. Best for 3D printing enthusiasts who need clean, watertight STL files without the randomness of generative AI. Lacks the creative flexibility of Meshy or Tripo for unique character/object creation.
Polycam shines when paired with an iPhone Pro LiDAR sensor — near-instant mesh generation of rooms and spaces. Web app available with limited Android support. Free exports are locked to glTF and require publishing to Polycam's public gallery. Pro starts at $27/mo (expensive). Best for architects, real estate pros, and iPhone Pro owners. Android experience is significantly weaker than iOS.
Spline is a design tool first, AI generator second. It excels at creating interactive 3D web experiences — think portfolio sites, product animations, and landing pages. Free tier available. At $9/mo it's affordable. Not the tool for game assets or 3D printing — but if you need beautiful web-embeddable 3D without touching Blender, it's unmatched. AI features are more limited than Meshy or Tripo.
