Which should you pick?

These land in different categories in our directory, which reflects where each is strongest rather than a filing error. ChatGPT has the widest feature surface and the largest ecosystem of integrations around it. Claude tends to be preferred for long-form writing and for reasoning over large amounts of code or text. Gemini is the one that pays off if your work already lives in Google Workspace, because the integration is the product. The tiers no longer line up the way they used to: ChatGPT and Claude still meet at $20 a month, but ChatGPT Go and Google AI Plus have opened a rung under $10 that Claude has no answer to, and the top tiers now reach $200. At the $20 tier the honest advice is to trial the one that touches your existing tools.

Free tier available. Paid plans read in Serbian dinar: Google AI Plus 649 RSD a month with 400 GB of storage, Google AI Pro 2,599 RSD with 5 TB, and Google AI Ultra from 10,500 RSD starting at 20 TB. Read from Serbia, where the vendor serves local currency. Forcing a US locale, timezone and Accept-Language did not change it because the vendor geolocates by IP, so no USD figure could be confirmed and the USD price columns are left empty rather than carrying a conversion.
