Every medium, one current.
Estura is an infinite node-canvas where text, image, video and voice flow into a single piece of work — generated with your own keys, kept on your own machine.

Reach the models you already want — with your own key
Features
One surface where every current meets.
Every medium, the models that matter, and full control of your keys and files — on a canvas that works the way ideas actually move.
A canvas, not a chat box
Branch, remix and connect every idea on an infinite canvas. Your process isn't linear — your tools shouldn't be either.
From prompt to picture to motion to voice
Text, image, video and voice generation on one surface. Carry any result straight into the next node and keep building.
Your keys. Your machine.
Plug in your own provider keys. Every generation runs through your accounts; every file is encrypted on your device. No login, no lock-in.
Frontier models, one surface
Generate with Seedance, Flux, Nano Banana, Seedream, Kling and Hailuo — plus GPT, Claude and Gemini for text. The lineup keeps growing.
Edit, don't restart
Refine an image with a prompt, dial in aspect ratio, duration and resolution on video, and add a voiceover — right from the node.
Truly local
No accounts, no cloud project that can vanish. Your canvases and assets live as real files on your own disk.
How it flows
From scattered sources to a finished piece.
Plug in your key
Add your provider key once. It's stored encrypted, on-device — we never see it.
Open the canvas
Drop a node, write a prompt, pick a model. Generate an image, a video or a voice in a single click.
Let it flow
Connect one node into the next — a prompt into an image, an image into a video, a script into speech — until the streams converge into a finished piece.
The name
Where rivers meet the sea.
Estura takes its name from estuary — the place where rivers meet the sea. It's where countless separate currents, fresh and salt, fast and slow, converge into one of the richest, most alive ecosystems on Earth.
Creation works the same way. Your raw material arrives in separate streams: a line of text, a frame of image, a moment of motion, a thread of voice. Estura is where they meet — an open surface where every medium flows into one, until scattered sources become a single, finished work.
And because you bring your own keys, every current stays yours.
Why Estura
A tool you own — not a cloud you rent.
Most AI canvases run in someone else's browser, on someone else's servers, billing a markup on every generation. Estura flips that: a native app on your machine, your keys, your files.
Own your work
Projects and assets sit on your disk, as real files — not locked inside someone else's cloud account.
No lock-in
Bring your own keys and pay providers directly. Swap providers anytime; nothing ties you down.
No compute markup
We sell the tool, not your credits. You never pay a subscription tax on top of every generation.
Private by design
No account, no upload. Keys are encrypted by your OS keychain; your work never leaves your device.
FAQ
Questions, answered.
What does “bring your own keys” mean?
You create an account with a model provider, generate an API key, and paste it into Estura once. Your generations run straight through your own account at the provider's prices. There's no Estura server in between — and no Estura account to create.
How much does it cost?
Estura is a one-app license for the desktop tool (pricing announced at launch). Generation is pay-as-you-go to your model provider — typically cents per image and a few cents per short video. You only pay for what you make.
Is my data private?
Yes. Canvases, generated assets and API keys all live locally on your machine, with keys encrypted by your operating system's keychain. There's no account and nothing is uploaded to us — there's nothing to upload to.
Which models can I use?
Frontier media models — Seedance, Flux, Nano Banana, Seedream, Kling, Hailuo and ElevenLabs voice — plus GPT, Claude, Gemini and DeepSeek for text. You reach them through your own provider key, and the lineup grows over time.
Do I need to be technical?
No. Getting a key takes a few minutes and we walk you through it. After that it's drop a node, write a prompt, and generate.

macOS first, with Windows planned. Join the waitlist and we'll tell you the moment your platform is ready.
