What you can actually do

Six things buyers use this for

Not a feature list. These are the jobs people buy UsingOpen Studio to get done — and the reason it pays for itself in the first week.

Chat privately

Ask anything of a local model — your prompts and documents stay on your machine. No data sent to OpenAI, no API keys to manage, no per-token bills.

Train on your docs

Fine-tune on your company's PDFs, code, or notes with one click. Build a model that knows your domain without leaking anything to a third party.

Export to anything

Quantize and export to Ollama, llama.cpp, vLLM, MLX, or GGUF in one click. One workflow, every downstream target.

RAG & documents

Drop in PDFs, Markdown, or whole folders and let the model cite them. Built-in vector store and chunking — no separate database to host.

Images, audio, video

Generate and edit images with SDXL/Flux. Transcribe audio with Whisper. Caption video frames. All locally, all from the same app.

Providers, not lock-in

llama.cpp, vLLM, Ollama, MLX — switch backends without re-learning the UI. Bring your own OpenAI-compatible endpoint if you want to mix local with paid APIs.

Plus everything the open ecosystem ships next — you get it automatically
Will it run on your computer?

Plain-English system requirements

No jargon. If you can run Zoom, you can probably run UsingOpen Studio.

Falls back to CPU inference automatically. Slower, but you can chat, RAG, and export without a GPU.

Apple Silicon is first-class.

Metal acceleration works out of the box — no PyTorch CUDA setup, no Xcode wrangling.

Auto-detects your hardware.

On first launch, UsingOpen detects your GPU, picks the right backend, and selects a model size that fits your VRAM.

Who it's for

Built for the people who'll actually use it

Three groups keep showing up in our inbox. If any of these sound like you, UsingOpen Studio is built for your workflow.

Makers and tinkerers

You want to run the latest open models on your own machine — no API bills, no rate limits, no data leaving your computer.

  • Chat with Qwen 3.8 27B, GLM 5.3 Flash, DeepSeek 4.1 Flash and more
  • Generate images, transcribe audio, caption video — all locally
  • Export any model to Ollama or llama.cpp in one click
  • Bring your own OpenAI-compatible endpoint when you want to mix

Researchers and students

You need to fine-tune models on your datasets and ship them to where they'll be used. UsingOpen Studio handles the whole pipeline so you spend time on the research, not the devops.

  • Drop in JSONL, CSV, or Markdown datasets — chunking handled
  • LoRA, QLoRA, full finetune, and DPO exposed as presets
  • Auto-resume from checkpoint if your laptop sleeps mid-run
  • Export quantized weights ready for Ollama / vLLM / MLX

Anyone who's tried to set this up before

You've spent a weekend installing PyTorch, fighting CUDA, downloading models from Hugging Face, and writing scripts. UsingOpen Studio is the one-click version of all of that.

  • Installer handles Python, CUDA, Metal, and dependencies
  • First-launch wizard picks a model that fits your hardware
  • Built-in UI for everything — no terminal required
  • Updates are free while the project is alive

How to pay — 3 steps, ~2 minutes

  1. 1Send $19 USD via Wise

    Open Wise and send $19 (or the equivalent in your currency) with the UsingOpen payment link below. Wise handles currency conversion at the mid-market rate — no extra fees from us. Your payment carries the reference 085034.

  2. 2Email us your transaction ID

    The Wise payment page has no note field, so email your Wise transaction ID and the address you want your license delivered to, to [email protected].

  3. 3We verify your payment and email your license

    Within 24 hours (usually much faster), we match your transaction ID to the payment, generate your license key, and email it — along with the download link and install instructions — to the address you sent us.

What to include in your email

Send two things to [email protected]:

  • Your Wise transaction ID — it's in the payment confirmation Wise emails you.
  • The email address you want your license key and download link sent to.

The Wise payment page has no note field, so this email is how we match your payment to your key. Already paid and forgot to email? Just send the transaction ID and we'll sort it out.

Within 24 hours

We verify each Wise payment manually and email your license key. Usually much faster than 24h — but plan for it.

No subscription trap

One $19 payment, the app is yours. Updates are free while the project is alive. No renewal, no auto-charge, no card on file.

Real humans answer

Support goes to the team that wrote the app. Email us with anything — install questions, model picks, weird edge cases.

“One-time” — what does that actually mean?

You pay $19 once. You download the app. It keeps working — including all future updates while the project is actively maintained. There is no 12-month clock, no renewal price, no "Pro tier" upsell later. If a year from now we ship a major new version, that update is yours too.

Why Wise instead of Stripe / LemonSqueezy?

Wise keeps the price at $19. Card processing and tax handling add cost on every sale, and those costs would have to come out of the price. Wise is peer-to-peer and works in 160+ countries. The trade-off: no instant key — we deliver manually within 24h.
