FAQ

Can you really skip one of them?

Yes, especially at the start. Most developers begin with one tool, master it, then add the second when they hit its limits.

Which hallucinates less?

Practically equivalent in 2026. Both can hallucinate on precise numbers, citations, legal or medical references. Always verify factual claims in an official source.

Which is better at French?

Claude generally has more nuanced French and better formal style. ChatGPT improved a lot with GPT-5 but sometimes stays slightly more American in phrasing.

Best value for money?

Nearly identical: $18-20/mo for both. Difference comes from usage, not pricing.
