Snapshot from each company's own plan page, checked on 2026-10-04. Plans change often, so go by the date.
ChatGPT: Plus is a paid plan billed monthly, per user. The pricing page also lists Go and Business. Source: https://chatgpt.com/pricing
Claude: Claude Pro is $17 a month on annual billing ($200 billed up front), or $20 billed monthly. Source: https://anthropic.com/pricing
Gemini: Google's Gemini subscriptions page lists paid plans above the free one. Its prices were not in the text fetched on 2026-10-04, so check that page before you pay.
The free plans' message caps and file sizes aren't on those pages, and they don't say which free plans include file uploads or voice, so check each app for those. Reply with what you need it for and which one you ended up using.
