Prices
First, Claude Pro costs $20 a month or $200 a year, and it also shows no ads. Google AI Plus, by contrast, costs $4.99 with 400 GB of storage, and Google AI Pro $19.99 with 5 TB, both billed monthly, as our Gemini pricing guide lists.
Perplexity Pro, meanwhile, also costs $20 a month or $200 a year, and verified students pay $10. Our comparison of AI plans and prices covers every tier.
Research and Sources
Perplexity, for example, cites every answer and had the lowest error rates in both the EBU and BBC study, at 30%, and the Tow Center’s citation tests. Gemini, however, had significant issues in 76% of news answers in the same EBU and BBC study.
Gemini still offers Deep Research on its free plan, and Gemini Notebook answers from your own sources, as our NotebookLM review explains. Claude, meanwhile, runs Research with citations on paid plans, but the EBU and BBC study did not test it. Our list of the best AI for research is ordered by those studies.
Writing and Coding
First, Claude’s Opus 5.5 placed first on Arena’s creative-writing board of September 25, 2026, and Claude Code leads the agent index, as our Claude Code review covers. Our guide to Claude for writing also covers drafting.
Gemini, in addition, writes inside Gmail and Docs, and Google’s Antigravity agent scored 41.9 on BenchLM’s mirror of the index. Perplexity, by contrast, has no coding agent of its own.
Data and Privacy
On data, all three also train on chats by default on personal plans. Claude, for example, turns it off under Help improve Claude, and Gemini follows Keep Activity.
Perplexity’s opt-out, however, covers only new data. Our guide to which AI tools train on your data compares each rule.
Winners by Category
In short, Claude wins on independent scores, writing and coding, for example. Gemini, meanwhile, wins on price and storage, and Perplexity on sourcing accuracy.
Overall, therefore, in Claude vs Gemini vs Perplexity our scores favor Claude, at 3.6, ahead of Gemini and Perplexity at 3.4 each.
Which One to Choose
Therefore, take Claude for writing, analysis and code. By contrast, take Gemini if price or Google apps matter most, and Perplexity for research you need to cite.
