Just say what changed. The sheet updates itself.
Connects and works with your existing subscriptions
Talk to the same assistant in both modes. Analyst coordinates research, documents and scheduled work. Developer coordinates the full project, terminal, browser, Git and specialist tools. Both run through the local desktop engine.
See the two modesAnalyst and Developer are the front door. Install only the focused workspaces you need; they share the same projects, permissions and local engine.
Draft cited documents, edit them in place, and keep the result beside the work it came from.
Your apps already hold the work. Speak the outcome, and Upfyn coordinates the context and approved actions across them — turning your machine into your own AI assistant.
You work with one assistant, not a cast of characters. Under the surface, Upfyn separates orchestration, planning, context, execution, verification and memory so each stage has a clear job.
The six responsibilities are named for Indian minds, and each name reflects a working method taken from what that mind taught, built into the system. None of them is the historical figure, speaks for them, or carries their authority.
Some stages reason with a model; others are deterministic software. The separation matters because permissions, context and checks should not depend on a model remembering to behave.
About the namesUse cases
Twelve jobs, each written out end to end — what it costs you now, the steps to hand it over, and what you are holding when it is done.
Models are a resource, not the product. Use UpfynAI credits, your own provider key, a local model, or a supported CLI subscription.
Your projects, permissions, tools and two-mode workflow stay the same when the model changes. Fast mode requests priority processing from supported models without reducing their reasoning depth.

Works with what you already use
Connect the model providers and the tools you already have set up — your keys, your subscriptions and your data stay exactly where they are. From then on Upfyn is the only application you open: mail, calendars, drives, trackers and hundreds more, all worked from one place.
