Switching into AI

Break into AI without paying tuition

A curated path for career switchers: paid residencies and fellowships that hire you to learn, founder programs that back people before they have a company, and the free courses with reputations earned over years. Every entry was checked for cost first. Paid bootcamps did not make the list.

Founder routes

If the switch you want is into founding, these back people before companies exist. None charges a fee to apply.

Free courses worth your time

Self-study routes with reputations earned over years, not marketing. All free; where a paid tier exists, the card says what it actually gates.
