Already inside the IDE a large part of the profession uses, with the refactoring and inspection tooling around it that no chat window has.

The categories JetBrains AI is listed in, and how strong a fit it is in each.
Programming, debugging, data analysis, spreadsheets, math, engineering, technical research.
JetBrains AI has a free plan. AI Free tier, included with every IDE subscription
The AI is sold as part of the IDE subscriptions rather than on its own, so the published figures are IDE prices with AI included.
Tools that do comparable work, best fit first, drawn from the catalogue rather than hand-picked. Every one is listed whether or not there is money in it for us.
Best general option for explaining unfamiliar code, debugging a single file, or analysing a spreadsheet with real Python behind it.
View ChatGPT →Reads long files and whole error traces without losing the thread, which makes it good at explaining unfamiliar code and debugging in a chat window.
View Claude →Reviews pull requests line by line and leaves comments in the diff, with the reasoning attached rather than a score.
View CodeRabbit →The editor most professional developers have converged on. Understands a whole codebase, not just the open file.
View Cursor →The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use.
View GitHub Copilot →Upload a spreadsheet and it writes and runs real code against it, showing the working rather than describing it.
View Julius AI →Where JetBrains AI sits in the wider category pages.
Strong fit — Programming, debugging, data analysis, spreadsheets, math, engineering, technical research.
Yes — AI Free tier, included with every IDE subscription. The cheapest paid tier is dotUltimate, which bundles AI Pro, at $21.90/mo.
Already inside the IDE a large part of the profession uses, with the refactoring and inspection tooling around it that no chat window has. It is listed under Coding, Data & Technical Work.
Sold inside an IDE subscription rather than separately, so these are IDE prices. The cheapest IDE is not the cheapest route to the paid AI: IntelliJ IDEA Ultimate is $19.90 a month and bundles only the free AI tier. Students, teachers, classrooms, open-source maintainers and user groups get the tools free.
6 tools do comparable work: ChatGPT, Claude, CodeRabbit, Cursor, GitHub Copilot, Julius AI. 6 of them have a free plan.
