Bring your own API key: what BYOK means and why it usually costs less — BYOK (bring your own key) means you pay the model maker directly at API cost instead of a flat monthly subscription. Here is how it works in More AI, what it costs in practice, and how to keep spending under control.
Cowork: turn any folder into an AI project workspace — Cowork binds the assistant to a folder on your disk. It reads your files, edits documents with visible diffs, generates Word, Excel and PowerPoint deliverables, and keeps a live checklist while it works — all locally.
Code mode: run a coding agent on your own repository — Describe a task, get a plan, approve it, and watch the agent write code, run commands and show you every diff — on your repo, with your key, under an explicit permission model.
Routines: schedule AI tasks that run on your machine — A routine is a saved prompt on a schedule — daily, weekly, hourly or on demand. It runs headlessly through your own key, saves the result as a conversation and notifies you when it’s done.
