Planar is a local studio for image generation — from a one-click result to iterative, instruction-driven refinement. Diffusion and beyond, on the hardware you already own.
Most images aren't right on the first roll. Planar's refine loop lets you describe a change in plain language — "make the sword glow blue" — and applies it with an instruction-edit model, without re-rolling the whole image.
The same app handles a one-line prompt and a deep model-management workflow — and it does it on every platform you work from.
One codebase across Apple Silicon, Intel Mac, Windows x64 and Linux. Switch machines without relearning the app or rebuilding your setup.
macOS · Windows · LinuxExtend Planar with WASM plugins — no network or filesystem access by default. Load one, activate it, and batch-run it across every image in your gallery.
WASM · no WASI · plugin APIBecause it speaks Hugging Face Diffusers natively, Planar runs the newest research checkpoints the day they drop — not months later.

ONNX runtime · bg removal bundledGeneration runs on your hardware. No uploads, no prompt telemetry, no queue — your work never leaves the machine.
No cloud · no accountDrive Planar from an agent session over MCP — queue jobs, poll status, stream results — while the same queue powers the UI you click through by hand.
MCP server · async job queuePoint it at a folder or a Hugging Face repo. Planar detects the architecture, picks sane VAE and sampler defaults, and loads — swapping backends without leaving your project.
Run the same project on whichever engine fits the job — a lean quantized runtime or the full research stack. Pick per project, swap anytime, no reinstall.
Planar runs any ONNX image model as a plugin, sandboxed with no network or filesystem access. One ships in the box; drop in the rest.
