One account, every surface
App, Build and VYN share a single identity, plan and usage ledger. Start a thought in one place and finish it in another.
Vynthen — one intelligence layer
Intelligence that feels inevitable.
A chat interface that stays out of the way, a builder that turns a sentence into a working site, and a coding agent that lives on your machine. One account, one model catalogue, no theatre.
01The products
Three surfaces.
One intelligence.
Each product is complete on its own. Together they share the same account, the same plan, and the same model catalogue — so a conversation can become a site, and a site can be finished in your editor.
Vynthen App
A quiet place to think.
A fast, uncluttered chat that streams from the model you chose. Markdown, code, images and long context, without a dashboard in the way.
- Every model your plan includes, in one selector
- Image input on the models that can see
- Conversations that stay yours — export or delete anytime
app.vynthen.com
Vynthen Build
From sentence to a working site.
Describe what you want. Build writes real HTML, CSS and JavaScript into a workspace you can open, edit and keep — with a live preview after every change.
- Watch the preview update as the agent works
- Plain files you can download, host anywhere, keep forever
- Included on every plan, including Free

VYN · CLI
Your machine. Your rules.
A coding agent that reads your repository, edits files, runs commands and shows you exactly what it changed. It lives in the terminal, next to your tools.
- Reads the repo before it writes, and asks before it commits
- MCP servers and bring-your-own-key on the plans that include them
- One Rust core shared with the Vynthen platform

02The system
What stays
constant.
The surface changes with the task. The rules underneath do not: one account, honest limits, server-side authorization and your data kept yours.
Plan-aware model access
The selector only offers what your plan includes, and the server checks again on every request. No client-side trust.
Streaming, not waiting
Tokens arrive as they are produced, with a real stop button. The interface never pretends work is happening.
Images, when you need them
Generate images inside App and Build on every plan that includes them. Labelled, stored privately, never used for training.
MCP integrations
Connect the tools you already use to VYN on Pro and above. The agent asks before it touches anything outside the repo.
Bring your own key
BYOK unlocks the full catalogue on your own OpenRouter account. Keys are encrypted at rest and never shown again.
03The catalogue
Every model,
honestly labelled.
No mystery routing and no silent downgrades. You pick the model; we enforce the same eligibility on the server that this page shows you. BYOK unlocks the full catalogue .
