Copilot is sold separately from Microsoft 365 Copilot and aimed at a different job, which is why both appear on this site.
Also from GitHub: GitHub.
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 →Upload a spreadsheet and it writes and runs real code against it, showing the working rather than describing it.
View Julius AI →Built for people who cannot code. Describe an app in plain language and get something deployed.
View Lovable →Where GitHub Copilot sits in the wider category pages.
Built for this — Programming, debugging, data analysis, spreadsheets, math, engineering, technical research.
Yes — Free tier, 2,000 completions a month. The cheapest paid tier is Pro, at $10/mo.
The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use. It is listed under Coding, Data & Technical Work, and this is what it is built for.
Suggestions are strongest on common patterns and weakest exactly where your codebase is unusual. Pro and above bundle a monthly credit allowance, so premium-model work is metered on top of the seat.
6 tools do comparable work: ChatGPT, Claude, CodeRabbit, Cursor, Julius AI, Lovable. 6 of them have a free plan.
