Scope, sources and honest limits
What these lessons cover
We compared public program descriptions on October 21, 2026, to identify core beginner skills. AstraCruz’s explanations, scenarios, exercises and questions are original. We did not copy course lessons, tests, videos or branding.
The comparison is about topics, not equal depth, accreditation or endorsement. We did not enroll in or audit every lesson. Some source pages were partially accessible.
| Program and evidence | Publicly described focus | AstraCruz coverage and limits |
|---|---|---|
| OpenAI Academy · Course descriptions | AI basics, prompting, reviewed workflows and agents; additional technical and leadership offerings. | Lessons 1, 4–6 and 8–12 address beginner use and oversight. No developer-course, assessment or credential equivalence. |
| LearnFree public catalog | Practical digital skills and AI activities, including prompts, work updates and customer communication. | Lessons 4–9 and 12 apply these broad skill areas. Detailed AI syllabus was not fully retrievable; exact course coverage remains unverified. |
| Elements of AI · University of Helsinki syllabus (2018) | Conceptual AI, problem solving, uncertainty, learning methods, neural networks and implications. | Lessons 1–3 and 9 introduce these areas. The accessible university syllabus is historical; current course depth was not fully verified. This series does not reproduce its mathematical exercises, peer review or credit requirements. |
| DeepLearning.AI: Generative AI for Everyone | Generative AI capabilities, practical use, projects and effects on business and society. | Lessons 1, 4–11 cover the introductory concepts. Public search-indexed course outline was accessible; direct retrieval returned an access error. No equivalent video course, technical labs or graded assignments claimed. |
| Google AI Essentials | AI basics, productivity, prompting, responsible use and keeping skills current. | Lessons 1 and 4–12 address these core skills with original exercises. No Google credential or course-completion equivalence. |
What makes AstraCruz useful
Each skill has a personal and business application. You finish with an inspectable draft, checklist or decision record. Free text lessons work without an account; live demos are optional. This is AstraCruz’s approach, not a claim that other programs lack practice or human review.
Where to go deeper
For detailed algorithms, mathematics, model training, programming, production integrations or formal assessments, consult the providers’ current programs. This series introduces those boundaries without pretending to teach full implementation. Access terms and prices elsewhere can change; no enrollment or purchase is needed here.
