See It in Action
From AI-powered damage detection to multi-part splitting with joinery — everything runs in your browser.
What No Other Slicer Can Do
Three capabilities unique to Karaslice. No desktop slicer — free or paid — offers any of them.
AI Smart Split
Upload a car body shell and the AI identifies doors, hood, fenders, and roof as separate parts. Upload an action figure and it finds arms, legs, torso, and head. Semantic decomposition with assembly guides and auto-generated joints.
Pro FeatureCloud Printer Export
Slice in your browser, then send GCode directly to your printer. Supports Bambu Lab, Creality Cloud, OctoEverywhere (OctoPrint/Klipper), and Prusa Connect. Monitor temperatures and print progress live.
Pro FeatureCentral Brain AI
An autonomous AI that learns from every mesh you process. It predicts optimal slicer settings, detects failure-prone geometry, and deploys improvements weekly — without waiting for manual releases.
Always ActiveEverything You Need to Print
Proprietary slicer engine, cloud processing, AI mesh repair, and 3D generation — the complete pipeline.
AI Mesh Repair
15-stage cloud pipeline fixes non-manifold edges, fills holes, corrects normals. Handles files up to 250MB.
AI Region Edit
Select faces with lasso, box, or anchor; describe an edit in plain English; an agent dispatches Meshy / Rodin / Llama-Mesh and stitches the result back seamlessly.
C++ Slicer Engine
9 infill patterns, Arachne perimeters, adaptive layers, ironing, fuzzy skin, multi-color GCode with wipe tower.
Split for Printing
5 split methods with multiple cut planes, dowel joinery, and auto-slice for oversized models.
Cloud Processing
32GB/8vCPU cloud slicing. Smart router auto-picks local WASM or cloud based on mesh complexity.
AI 3D Generation
Generate meshes from text prompts or 1-4 reference photos. AI remesh and PBR retexturing.
Thicken & Hollow
Reinforce thin walls with Hollow / Partial / Solid fill, or hollow with vertex-normal offset. Pro tier unlocks gyroid / honeycomb / cubic lattice infill.
3D Toolpath Preview
Color-coded walls, infill, support, and travel moves. Layer slider with per-type visibility.
Paint Tools
Brush seam, support, and color masks directly onto the mesh. Per-face persistence; survives slice + export.
Printability Analysis
Overhang detection, wall thickness estimation, printability scoring, and support preview.
Terminal & AI Agent
VS Code-style terminal with 25+ commands. AI mesh agent executes repairs from plain English.
Conform (Shrinkwrap)
Fit one mesh onto another's surface (Blender-style Shrinkwrap). Great for skinning, kit fits, and assembly seams.
Three Steps to a Perfect Print
Upload
Drop any STL, OBJ, GLB, 3MF, or FBX file. The viewport loads instantly with PBR rendering and automatic AI analysis.
Repair & Slice
AI classifies damage and recommends the best repair path. Slice with 42 printer profiles, adaptive layers, and Arachne perimeters.
Print or Export
Send GCode directly to your printer via cloud. Or download repaired STL/OBJ/ZIP with assembly guide.
Your Data is Yours
Your 3D models are yours — we never access, share, or sell your files. Our ML pipeline learns from anonymous metadata only. Your meshes and IP are never used for training.
Authenticated Access
Firebase Auth with Google, Apple, and email sign-in. Every API call verified. Admin 2FA enforced.
Isolated Storage
Files stored in user-scoped paths. No cross-user access. UID-enforced security rules. Encrypted credentials. PII hashed at rest.
Google Cloud
Firebase App Hosting, Cloud Functions v2, Firestore, Cloud Storage. Enterprise-grade infrastructure.
2,900+ Tests
Vitest, pytest, brain comprehensive, iOS XCTest, and a 2,186-mesh nightly regression corpus. CI/CD on every commit.
