Are Free AI Tools Actually Good Enough?
This is the most common question we get. The answer: for most people, yes. The free tiers of ChatGPT, Claude, Codeium, and Perplexity are genuinely powerful — they're not artificially hobbled demos. The limitations are typically around message caps, response length, or premium features like longer context windows.
Our advice: start with free tiers. Use them for at least a month. If you hit a limitation that actually blocks your workflow, then consider upgrading. Many users find that free tiers cover 80-90% of their needs.
