Daily 15-minute AI lessons that build real, practical skills
A new lesson lands in your inbox each weekday morning, designed to be completed in about 15 minutes.
Progresses from how AI models work, to building prompts and automations, to embedding AI into your daily workflow.
Lessons pair each concept with a real work task so you produce usable outputs, not just notes.
Everything runs through your existing email and whatever AI tools you already use; no installs or coding environment.

Practical AI bootcamps for marketing, sales and design teams
Separate tracks for marketing, sales and design professionals, so the use cases and exercises match the work each cohort actually does.
Roughly 60% of time is spent applying AI tools to real tasks and 40% on theory, with participants leaving with reusable workflows.
About 24 hours of training across roughly four weeks, mixing 90-minute live workshops with asynchronous self-study.
Participants are grouped with people from the same profession, creating room for exchange, benchmarking and mutual support.
