The free-only stack that works
For most casual users in 2026, the “don’t pay for AI” stack is: Claude.ai free for writing + reasoning, NotebookLM for research, Bing Image Creator for images, ChatGPT free for the times you hit Claude’s daily limit. Total cost: $0/mo.
When free becomes painful
- You hit Claude / ChatGPT daily caps regularly — pay $20 for one of them.
- You need image gen at brand-marketing quality — Midjourney $10/mo.
- You’re building anything API-driven — you’re past free tiers anyway.
- You need a paid feature only available behind the paywall (Sora, Veo, Code Interpreter, Custom GPTs).
