We build the assistant we wanted to use
Plexa AI, LLC is the company behind Jervis. We started because serious work still meant stitching together a research tool, a writing tool, an image tool and a spreadsheet. Jervis collapses that into one place: you describe the outcome, it plans the steps, runs them and hands back the finished work.
One assistant, not ten tools
Jervis handles research, agents, media and publishing in a single thread — no tab juggling, no prompt gymnastics.
Zero-hassle by default
No mode pickers or model menus. Jervis reads intent and picks the right path automatically.
Real infrastructure
Dedicated compute nodes with live status, contracts and invoices — not a thin wrapper on someone else's API.
Security first
Row-level access rules, encrypted secrets and admin-only controls guard every workspace.

Explore the Plexa Dusk themeAbout Plexa AI and the Jervis assistant
Plexa AI builds one calm workspace for AI research, writing, agents and creation, led by the Jervis assistant. The goal is simple: fewer tools, clearer answers, and work that finishes inside one place.
One workspace instead of many tabs
Research, documents, images, automation and support live under a single assistant with shared memory of your projects.
Answers you can check
Sourced research, visible steps and honest limits matter more to us than confident-sounding text with nothing behind it.
Built for real daily use
Fast on mobile, readable on desktop, and designed for long sessions rather than quick demos.
Independent and evolving
Jervis keeps its own memory and skill library, so the workspace improves with use rather than resetting each session.
