Spend your time on the art. Not the busywork.
Loopcut is an open-source agent inside Blender. It reads your scene, writes and runs the Python, and shows you what changed. Every step is one undo away. You keep the mouse.
Free with your own API key or a local model. Hosted models from $0 a month.
Reading the scene… 47 objects, 6 materials, 3 lights. I'll rename by material, group the lights, then add key, fill and rim aimed at Bottle.
for ob in col.all_objects:
if ob.type == "MESH" and ob.active_material:
ob.name = f"{ob.active_material.name}_{i:02}"
lights.objects.link(light) # × 3Checked the viewport. 41 objects renamed, 3 lights in Lights, rig placed at 45°, 120° and 200°. Rim looks strong; want me to drop it to 60%?
What we heard from artists
70%
of time in Blender goes to technical work, not creative decisions.
We surveyed the people who use Blender every day. Most of their hours were not spent sculpting, composing or animating. They were spent on the work around the work. That part is what Loopcut takes on, so the remaining hours are yours.
- Naming and organising
- UV seams and packing
- Retopology cleanup
- Modifier stacks
- Render and output settings
- Driver expressions
- Batch exports
- Fixing normals and scale
- Light rigs and cameras
- Repetitive edits across files
How it works
A technical director in the panel next to your viewport.
No new tools to learn and no export step. Loopcut lives inside Blender, works on the file you have open, and explains itself as it goes.
- 01
Say what you want
In plain words, in a panel docked next to your viewport. Loopcut reads the open scene first, so it talks about your objects, not a blank file.
- 02
It writes the Python and shows you
Every step is real bpy you can read before it runs. Approve once, or let it run for the rest of the conversation. Nothing happens off screen.
- 03
Check the viewport, keep or undo
It looks at the result, tells you what changed, and drops a checkpoint. Every turn is one click back, even ones a plain undo can't reach.
Where we stand
Built for the person holding the mouse.
A lot of AI is aimed at replacing artists. Loopcut is aimed at the parts of the job artists never asked for. Here is what that means in practice.
You direct. It executes.
Loopcut does not generate art from a prompt. It does the technical work you would hand to a TD, against the scene you built.
Nothing runs unseen
The code is on screen before it runs, and the result is checked in the viewport. You always know what happened and why.
Your work stays yours
Scenes stay in Blender. With your own key, requests go straight to your provider. With ours, we count tokens and store nothing else.
Open, end to end
The agent, the Blender build and this site are open source. Read it, fork it, point it at a local model, or help make it better.
Who it is for
One tool. Two kinds of day.
For artists
Get the hours back
Character, environment, motion design or hobby projects: hand off the cleanup, the naming, the rigs and the render settings, and keep the decisions.
- Clean and organise scenes in one sentence
- Set up rigs, drivers and constraints without the docs open
- Fix the fiddly things: normals, scale, UVs, modifier order
- Learn as you go: every step is readable bpy
For studios and teams
Ship 3D at the speed of the brief
Product photography, animation for the web, explainers for YouTube, configurators. Repeatable output without a scripting team on call.
- Studio light rigs and turntables from a sentence
- Batch colourways, variants and exports
- Consistent camera and render presets across files
- Your company's API key or our hosted models
Models
Your models or ours. Your call.
Loopcut speaks to any OpenAI-compatible endpoint, so the agent is never locked to one vendor. Run it three ways.
Bring your own key
Paste a key from any provider. The key stays on your machine, requests go straight to them, and Loopcut never sees your traffic.
- Any OpenAI-compatible API
- No account needed
- Pay your provider directly
Run it locally
Point Loopcut at a model on your own GPU. Nothing leaves the building, which some studios and a lot of artists prefer.
- Works offline
- Fully private
- Any local server with a chat endpoint
Hosted by Loopcut
Sign in from the app and start. Two modes, Fast and Pro, on models we pick and configure for Blender work. No keys, no setup.
- Fast for quick edits, Pro for hard scenes
- Metered by model time, shown in the app
- Free tier to try it
Hosted plans fund the project. Bringing your own key will always be free and never second-class.
Open source
Nothing to trust on faith.
The agent loop, the tools, the Blender build and this website are all in the open. If you want to know what Loopcut does with your scene, read the code. If you want it to do something else, change it.
Hosted plans
Free, Pro and Max.
Plans buy model time in a 5-hour session and a weekly window, so you always know what you have left. Upgrade when the work asks for it.
Make the thing. Let the busywork run itself.
Download Loopcut, open the file you were dreading, and ask.
