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 created by Jeremy Andrews, CEO of Tag1 Consulting, to manage the overhead of running a company with nearly 100 people across 25+ countries while raising a family in Tuscany. The setup has changed how he works enough that people kept asking for the details. This site is those details.

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.
