1. Tired of Fake Free Trials? The Anti-Paywall Manifesto
We’ve all experienced it: you search for a "free AI tool", spend ten minutes creating an account, type your first prompt, and immediately slam into a full-screen modal demanding your credit card for a "7-day trial" that auto-bills $49/month if you forget to cancel.
Enough of the marketing traps. As a budget-conscious builder and student, I test dozens of tools personally. This free AI tools list curates 25 genuinely free tiers, open-source projects, and generous developer sandboxes that give you frontier AI power with no credit card required.
