Introducing Vellio
One workspace for every AI model — prompt library, multi-model chat, hosted credits, and a browser extension. Here’s why we built it.
Vellio is a single workspace for the way people actually use AI today: save the prompts that work, chat across models side by side, and keep your library with you in the browser.
Prompt library that stays yours
Great prompts are assets. Vellio lets you organize, version, and reuse them — then publish to the community marketplace when you’re ready. Browse categories on Explore, or jump into coding helpers like Pull request reviewer.
Multi-model chat in one place
Switch between GPT, Claude, Gemini, and more without juggling tabs and API dashboards. Compare outputs in the same thread, bring your own keys, or start with hosted credits — no card required to try.
Hosted credits when you want them
BYOK stays first-class. Hosted credits are there when you want a fast start or a spare lane without wiring every provider key on day one.
Extension for the rest of the web
The Vellio extension puts your prompt library next to the AI tools you already use, so the best phrasing travels with you.
What’s next
We’re opening the public site, the marketplace, and the blog so more people can find Vellio the same way they’ll use it — openly, and on their own terms. If you’re ready to try it, create a free account.
