At a glance
Start free, nothing to install.
All-in-one, no install
No downloads, no updates, no hardware worries. Creation, editing, review and live checking flow together in a single browser.
Import that starts by fixing
Common problems in files exported from other tools — unit mismatches, duplicated bones, broken skeletons — are diagnosed and repaired the moment you open them. Opening "unopenable" files is itself a feature.
A validation gate that guards quality
Before export, required conditions are checked automatically so files that external engines or other tools would reject are never produced.
Privacy minimalism
Webcam video never leaves your device, and social-login identifiers are stored only in an irreversible form.
Five languages
日本語 · English · 한국어 · Bahasa Indonesia · 中文. Every app and the help pages follow the same language setting.
What you can do
Four apps connected in a single pipeline.
Viewer — where review starts and ends
viewer.dasoni.app
Play VRM/animation (VRMA), check model info and licenses, switch chroma backgrounds and themes. Finish your final pre-release check fast.
Editor — VRM creation that honors the standard
editor.dasoni.app
Drag in fbx, glb or gltf and VRM production begins. Rig-name standardization (Unreal Mannequin/MetaHuman, HumanIK/Mixamo, 3ds Max Biped), automatic humanoid mapping, T-pose conversion, toon-shading conversion, automated expressions, physics and eye gaze — plus precise manual editing and undo for everything.
Live — check your finished avatar with a webcam
live.dasoni.app
Track face, head, fingers and upper body in real time to see your edited VRM move as intended. Video never leaves the browser. Instant hand-off of the model you are editing — check it right away in preview.
My Storage — continuity of work
dasoni.app
Automatic version numbering, project folders, history that recognizes identical files. Local drafts are saved automatically, so closing the tab never loses your place.
Who it's for
Beginner or pro, everyone works to their own goal from a single browser.
VTubers & streamers
Check face, head, finger, and upper-body tracking instantly with just a webcam. Verify your avatar moves correctly before going live. Video never leaves your device.
3D artists & modelers
Bring rigs from Maya, Blender, 3ds Max, or Unreal to the VRM standard. Rig-name normalization, automatic humanoid mapping, and a validation gate keep everything to spec.
Creators & illustrators
Finish characters made in VRoid and others with toon shading, expression presets, and physics. No 3D knowledge needed — it's all button by button.
Game & app developers
Reliably produce VRM that external engines won't reject. Missing required bones and hierarchy violations are blocked before export.
Beginners & hobbyists
Start free in the browser — no install, no spec worries. Drop in a file and your first VRM is made.
Automation pipeline
Conversion steps that took hours by hand, reduced to buttons. Every automation shows a preview before applying.
Bone naming · bone mapping
Recognizes Unreal Mannequin/MetaHuman, HumanIK (Maya/MotionBuilder/Mixamo), 3ds Max Biped, Blender Rigify (new and legacy bone naming) and Unity Humanoid rigs, renames them to the standard in one pass and auto-maps all 55 humanoid slots.
T-pose conversion
Direction-alignment based, so results are consistent regardless of each file's A-pose angle.
Materials · expressions
Converts standard materials to toon shading (MToon) in one pass, detects VRoid, ARKit and Japanese-style morphs and binds expression presets automatically.
Physics
Detects hair and clothing sway chains, applies presets and places colliders automatically. Extended colliders (inside and plane types) are supported.
Meta presets
Pick a scenario — personal, distribution or free distribution — and license and permission fields are filled in at once, with a preview of the values to be applied.
Validation gate
Catches missing required bones, duplicate assignments, hierarchy violations and other causes of rejection by external engines before export, with per-item diagnosis.
GLB·FBX → live check in 10 minutes
A representative flow for standard humanoid rigs — actual time varies with the model. See the help pages for detailed steps.도움말에서 확인하세요.
Open · auto-restore
One drag. Units, duplicated bones and broken skeletons are corrected automatically, and problematic files are recovery-loaded so you can fix them.
Apply automation
Bone naming → mapping → T-pose → materials, expressions, physics, gaze. Each step can be previewed before applying.
Validate · export · live check
Confirm the validation gate passes, then export .vrm or save to storage. Turn on your webcam in Live to see your finished avatar in motion right away.
