Describe the outcome. The team ships it.
Jennefer picks the right specialist for each task. They design, build and test in order, and a consensus gate approves the result before it reaches you.

Jennefer Hub
Closed betaHome for every app. It shows what runs right now, which model every app uses and who holds the GPU.
More about HubThe cloud sends a bill. Your GPU doesn't.
Jennefer agents use the model on your own graphics card, so there is no per-token charge. The Hub still counts every token and shows what a cloud model would have billed for the same work. Pick a Nefer's month.
110M input and 3.85M output tokens this month
That's a whole holiday. Staying local.

An estimate, not a quote. Prices as of October 19, 2026 from each provider's public price page, at standard rates without cache, batch or off-peak discounts; hover a model for its source. Cloud models count tokens with their own tokenizer, so real numbers differ, and your computer still uses power. The months above are examples: Jennefer Hub > Usage shows your real token counts per app and model, and only the counts are kept, on your computer.
Hand over the goal. The crew does the rest.
Stop counting tokens.
Local models have no per-token bill and no rate limit.

Run models on your device and switch per chat. Your own endpoint or API key is available on request, after a short review.

Local models run on your hardware. Your endpoint's API key stays on your device. We never store your code or train on it.

Get one that thinks.
One sentence becomes a small Next.js app. Apps ask your own model for answers, so no API key lives in the code.

- Next.js and Tailwind. Copy any app into a project and keep building it in the editor.
- AI built in
- Apps ask your model through the Jennefer bridge. Switch models and every app follows.
- Nothing to host
- Static apps with a small local store. No server code and no database to run.
One crew. Many apps.
Every part of Jennefer is its own app, made for one job. Hub ties them together: one account, one plan, and your Credits work in every app.
Closed beta in
Jennefer Hub. Every app, one home.
Hub installs and updates your Jennefer apps and keeps them in tune. It opens with the IDE; the other apps follow. Sign in once, download each model and pack once, and let every app share them without fighting over your GPU. Pick a model for each app, see tokens and estimated cost in Usage, and link your phone for Jennefer Mobile.

Separate apps. One rhythm.
Each app does one job well, and all of them are built to work together from day one.
Send it anywhere
Make an image in Studio and drop it straight into a Cloud sandbox or an IDE project. No downloading and re-uploading.
One shared library
Images, videos, designs and apps you make land in one library that every Jennefer app can open.
Hand off between apps
When a Workshop app outgrows Workshop, move it into the IDE and keep building with the full team.
One account, one plan
Sign in once in Hub. Your plan and your Credits work in every app, and limits count once across all of them.

Zero per-token cost
Local model swarms
Run agent teams on models that run on your hardware, with the built-in local engine. No per-token rates, no monthly surprise bills.
Local models
Your models, your keys
Run agents on local models with the built-in engine. Your own provider endpoint is available on request, after a short review. Jennefer never trains on your code.
Jennefer Studio
Images, video and ads
Generate images, edit your photos, make clips with sound and design ads on your own GPU. Packs install from the Features hub when you need them.
Organizational agents
Living Org pipeline
Supervisors delegate to Architects, Developers, and QA engineers simultaneously. Each role handles specialized scopes with verifiable handoffs.
Coming soonLocal-first. No Jennefer servers. Just a license key.
Jennefer Premium is designed to run the agent team on your machine with local LLMs, activated with a license key and no Jennefer account. You can optionally add your own API key for a remote provider; prompts then go to that provider, never to Jennefer. Zero telemetry by default.
Not available yet. Features may change before release.
Jennefer Partners
Run a model cloud or publish open weights?
We add a short list of tested providers and local models to Jennefer. Apply to bring yours to every Jennefer app. There is no fee to apply.
Made by engineers who want a better way to build.
Jennefer began with a simple conviction: powerful development tools should give teams more control over their work, their infrastructure, and their ideas.
