ChatGPT
Fact sourceWhen to pick it Open the official pricing page, not an amount on this site, when you need to confirm ChatGPT has a free plan and then compare which of Go, Plus, and Pro includes higher Codex or image limits.
When to skip it The pricing page did not state a plan amount, and it did not say whether non-Search answers include clickable citations; both are unverified. If the job is reading one long document in a single pass, the closer directory record is Claude. If the job is running an open model on your own machine rather than a cloud subscription, the closer record is Ollama. This is not a ranked review.
Exact price not verified. Any pricing-model label describes a billing category, not a verified amount.
Grammarly
Fact sourceWhen to pick it Choose Grammarly when the same spelling and tone suggestions have to follow you across browser, desktop, and mobile apps, and you accept that full-sentence rewriting, plagiarism detection, and AI-generated-text detection all start at Pro.
