A personal assistant that runs continuously, holds context across sessions, and acts on its own schedule — not a chat window that forgets you the moment you close it. This is the system I use daily, and the main lesson has been that reliability matters far more than capability.

iThe problem

  • An assistant that forgets everything between sessions is not an assistant — it is a search box with extra steps.

  • Automations that fail silently are worse than automations that do not exist, because you keep trusting them after they stop working.

  • Capability is easy to add and hard to make dependable; most assistants die of unreliability, not of insufficient features.

iiThe approach

  • Durable memory on disk: curated long-term notes plus daily logs, so context survives a restart instead of living in a context window.

  • Scheduled work through a real scheduler rather than a model asked to wait — reminders and recurring jobs are engine-level, not promises.

  • Isolated execution for background tasks so a long-running job cannot stall the interactive conversation.

  • Every scheduled job reports its own outcome, which turns silent failure into a visible signal.

iiiWhat it produces

  • Runs unattended around the clock, handling digests, financial research, monitoring and scheduled briefings.

  • Continuity across sessions: decisions made weeks ago are still visible in today's behaviour.

  • The failure mode I designed against is the one I learned to fear — a job that stops working and says nothing.
