JustEdit
Pro-grade image edits in your browser. No upload. No tokens. No wait.
Every other AI image tool either ships your photo to a server, charges per second, or makes you download 175MB before it does anything. JustEdit runs the model in your browser, previews the result before it commits, and never sees your image. The whole product is built around respect — for your time, your bandwidth, and your privacy.
§01 — Case study
The shape of the work.
Pro background removal that runs in your browser. No upload. No subscription. No 175MB download surprise. The model lives on your device — your photo never leaves it.
Receipts — current traction
Every AI image tool is a tax on your trust.
Free tools watermark your output. Paid tools meter you per image. The 'open-source' option silently downloads 175MB and fails on hotel WiFi. Worst of all — every one of them uploads your photo to a server you'll never audit. For a category that calls itself 'AI for everyone,' the deal is bad.
Run the model on the user's device.
WebGPU and the right segmentation model (Xenova/segformer-b0, 30MB, cached forever) let me put a real production model in the browser tab. No upload. No API key. No edge function. The user's photo stays on the user's machine. The whole moat is built on respect.
“Your photo should never have to leave your laptop to lose its background.”
Preview before you process.
Big model + big image = big wait. So I added a state machine: upload → auto-resize → low-res preview → confirm → full-resolution process → download. The user sees the result before they spend the compute. Patience is no longer required because consent is asked first.
100% gross margin. 0% privacy debt.
Static hosting. No server. No tokens. No rate limits. The competition charges $9/mo for what JustEdit ships for free. And because the model never sees the network after the first load, the second visit works on a plane.
§01.5 — From the product
§02 — Story
Inception → Outcome
01 · Inception
Background removal is broken
Every option sucked. Free tools watermark you. Paid tools meter you. 'Open-source' tools shipped a 175MB model and silently failed on slow networks. There was no honest middle.
02 · Discovery
What people actually want
Talked to designers, marketplace sellers, and parents. Same answer: 'I want to crop my kid out of the background without uploading her face to a stranger.' Privacy wasn't a nice-to-have. It was the product.
03 · Decisions
Run the model in the browser
Picked Xenova/segformer-b0 over RMBG: 30MB vs 175MB, true segmentation, cached after first run. Killed the edge function. Killed the API key. Killed the upload.
04 · Build
Preview-before-process
State machine: upload → resize → low-res preview → user confirms → full process → download. No spinner the user doesn't understand. No compute the user didn't ask for.
05 · Ship
Zero infrastructure
No server costs, no rate limits, no quota panic. Static hosting and a service worker. Margins are 100% because cost is 0.
06 · Outcome
The honest option
First load is the only load. Second visit is offline-capable. The category leader charges $9/mo for what runs in your browser tab — for free, forever.
§03 — Outcomes
your image never leaves the browser — model runs on-device
model footprint — 6× smaller than the industry default
