You mostly use ChatGPT one question at a time. A self-hosted AI assistant (agent) finishes the job with your own tools, runs on your side, and plugs into the apps you use daily. Lesson one of building your own assistant from zero.

You don't need to write code to have your own AI assistant. An agent framework already packages the hard parts so you just install and go. Here's why you shouldn't wire it yourself — and why this series uses Hermes.

An AI assistant = a brain + a body. Use your ChatGPT account as the brain and Hermes as the body — one fixed combo, nothing to choose. Here's why it's set up this way, and what to have ready before you install.

Install the Hermes Agent desktop app — no terminal. Download it, let it auto-install dependencies, sign in with your ChatGPT account, and your first AI assistant is running in about 15 minutes.

Order your assistant around from your phone. Chat with one official Telegram bot, get a key (token), hand it to Hermes — done. No public URL, no webhook, no tunnel, because Hermes fetches messages from Telegram itself.

The last and most satisfying step: set up a task that runs itself. Tell it in plain words, and every day it researches what you care about, sums it up, and messages your Telegram. Set it once, close the laptop, and it pings you the next morning.

Your AI assistant only reads text? Give it eyes and ears — send a photo it understands, send a voice clip it understands. Not by swapping in a pricier model, but by bolting on a small vision model as a perception side-car. Hermes's built-in auxiliary.vision + faster-whisper, measured end to end.
