Jesse
Jesse is an AI assistant built from folders of text files, an instruction manual, and no vendor lock-in.
It pairs a sandboxed desktop AI agent with a structured vault of interconnected markdown files. A single instruction file tells the agent who you are, what your priorities look like, and exactly what to do when you start a session. The vault is your memory. The instruction file is your process. The AI is the engine.
Jesse was built to solve a specific problem: managing the daily overhead of a demanding workload (triaging email, tracking tasks across projects, preparing for meetings, keeping up with messages) without adding another app to the stack. Instead of a product, it’s a method you own and adapt to how you already work.

What Jesse Does
Each morning, Jesse runs a structured routine:
- Gathers information from your inbox, email, messaging apps, and calendar.
- Processes what it found: acts on instructions, extracts TODOs, flags meeting prep.
- Produces a prioritized daily briefing, updates your task list, and tells you what needs your attention.
The quality of the output is a function of the quality of your instructions. A vague instruction file produces vague results. A specific one produces something that genuinely feels like delegating to a competent assistant.
What Jesse Is Not
Jesse is not a product. There’s nothing to install, no account to create, no subscription. It’s a method: a vault structure, an instruction file, and a set of patterns for working with an AI agent. You bring the agent, you bring the editor, and you own everything.
