Which AI assistant should you talk code with?
You're not after another chatbot. You want the one that gets your error on the first try, sees enough of your project to answer right, and doesn't cut you off halfway through a session.
For a developer, picking an AI assistant starts with picking where the conversation happens. In a browser tab, it only sees what you paste. In your editor, it sees your open files. In the terminal, it acts on the repo. Prices look alike ($10 to $20 a month for the plan that matters), but the limits change everything.
The short answer. Want the best at reasoning, reviewing and design? Claude Pro, $20 a month, with Claude Code included for terminal work. Want an assistant that covers everything else too? ChatGPT Plus, $20. Want to chat without leaving VS Code? GitHub Copilot Pro, $10. Ready to switch editors? Cursor. Tight budget or need a European vendor? Gemini or Mistral Vibe.
Every price comes from the vendor's pricing page or our reviews, checked in 2026.
The ranking is editorial: a sponsored spot is always labeled on its card, and no affiliate link ever changes a score.
The right assistant for the job
The 6 AI assistants for developers, side by side
The "Where you chat" column answers the first question to ask: does the assistant see your code, or only what you paste in? The price shown is the plan you'd actually use for coding, not the teaser tier.
| Best for | Where you chat | Free plan | Team size | Visit | ||||

How we compared these assistants
Search "best AI for coding" and you'll hit two kinds of pages. Some throw autonomous agents, app builders and chatbots into one list. Others pit Claude against ChatGPT using model benchmarks that are already out of date. Hardly any tell you how much of your project the assistant can see, what happens when your allowance runs out, or whether your code trains the model.
So we compared these six on five things that matter when you code: where the conversation happens, repo access, real limits and how they're metered, the price of the plan you'd actually use, and privacy settings. For each vendor we read the official pricing page, then developer feedback on OpenAI's and Google's forums, Reddit and engineering blogs, starting with the unhappy ones.
Each tool's score is the one from its review, the same across all our pages. Rank follows score; on a tie, the “Features and depth” sub-score breaks it (4.6 for Claude vs 4.5 for ChatGPT, 4.5 for Cursor vs 4.4 for Gemini). Grok, DeepSeek and Perplexity sit outside the ranking, for reasons explained below.
These assistants change prices and caps several times a year. Get the changes that matter to you
Claude
If you could only pay for one assistant to talk code with, this would be it, by a narrow margin. Claude explains clearly, reviews carefully, and holds up across a long conversation. On developer forums it is the name that comes up most for accuracy, and the 2026 Stack Overflow survey puts Anthropic level with OpenAI on usage, with more developers saying they want to keep using it.
What sets it apart for you is the bridge between talking and shipping. From Pro ($20 monthly, $17 on annual billing), Claude Code is included: you work through a bug in the chat, then run the agent in your terminal against the real repo. In Projects you can also connect a GitHub repository. Claude reads the files on one branch (no commit history, no pull requests), and a sync button pulls in your latest push.
The catch is well known. Chat, the desktop app and Claude Code all draw on the same allowance, metered over a five-hour window and a weekly cap. One long agent session on a big repo can eat your chat budget for the day. On consumer plans, also check your training setting: opt in and your chats are kept for five years, opt out and it's 30 days.
- Claude Code included from Pro
- GitHub repo synced into Projects
- Long, structured answers
- ✓Most accurate on architecture questions and code review
- ✓Same plan covers chat and the terminal agent
- ✓$17/month on annual billing
- ✗Chat and Claude Code share one allowance that drains fast
- ✗Prices exclude sales tax
- ✗No Claude Code on Free
Our top pick for developers who want to understand before they write. Save the heavy agent sessions for when you need them, or the allowance runs dry by mid-afternoon. Limits are broken down in our Claude review, and the agent on its own in our Claude Code review.
ChatGPT
ChatGPT is still the broadest tool here. For a developer, that means one tab to explain a stack trace, crunch a CSV with code execution, look up recent docs and sketch an architecture diagram. It's also what most beginners already know, and it walks through code line by line without making you feel slow.
For real coding work, the piece to look at is Codex, OpenAI's coding agent. OpenAI includes it in every plan, Free and Go too, but only Plus and up get published usage estimates per five-hour window. Go, at $8, also keeps the ads: if you're buying to code, Plus at $20 is the real starting point.
The weak spot is limits. On OpenAI's community forum, Plus subscribers complain about hitting the Codex cap far too quickly. OpenAI sets no fixed cap: its docs publish message ranges per five-hour window (15 to 160 on Plus, depending on the model) and point you to the usage dashboard. If you live in Codex all day, you need Pro, from $100, not Plus.
- Codex on every plan, free included
- Code execution and file analysis
- Most versatile outside of code
- ✓One tool for code, research and documents
- ✓Great teacher when you're learning
- ✓Connectors for GitHub, Drive and Slack
- ✗Go keeps the ads
- ✗Codex limits come as ranges, not fixed caps
- ✗Users find it less precise than Claude on long refactors
Tied with Claude on score, second because its “Features and depth” sub-score is a notch lower (4.5 vs 4.6). Pick it if your assistant has to cover everything else too. Every plan is in our ChatGPT review.
GitHub Copilot
Copilot isn't just GitHub's autocomplete anymore. Its chat sits in your editor, sees your files and repo, and lets you pick the model that answers. For a quick question about the code in front of you, that beats a browser tab where you have to paste everything in.
Pricing moved to credits in 2026 (one credit is $0.01). Pro is $10 a month with $15 of credits, Pro+ is $39 with $70 and the premium models such as Opus, and Max is $100 with $200. Good news: completions and next edit suggestions don't use credits. Chat, agent mode and code review do, so heavy chat users feel it.
One setting to change right now on a personal account: since 2026, interactions on Free, Pro, Pro+ and Max are used for model training unless you switch off the option in your GitHub Copilot settings. Business and Enterprise accounts are excluded.
- Chat in VS Code and JetBrains
- Choice of models
- Free tier, no credit card
- ✓$10 Pro is the cheapest paid entry here
- ✓Completions don't touch your credits on paid plans
- ✓Sees your repo, no copy-paste
- ✗Chat burns credits, which go fast on Pro
- ✗Training on by default for personal accounts
- ✗Weaker than a dedicated chat for non-code questions
Best value for talking about code right where you write it. Plenty of developers pair it with Claude or ChatGPT for the big questions. To weigh it against direct rivals, see our Copilot alternatives.
Cursor
Cursor takes the Copilot idea further: the whole editor is built around the conversation. It indexes your project, understands how files depend on each other, and applies the edits you approve. No more copy the error, paste it into a chat, paste the fix back into the right file.
Read the pricing carefully, because there's a trap. Plus at $8 a month only gives you xAI's Grok models. If you want Claude or GPT, you need Premium at $30, where third-party models are billed at API list price on top. Super ($100) and Ultra ($200) give you 15 and 50 times the Plus allowance.
Turn on Privacy Mode at install. With it on, your code isn't used for training. With it off, Cursor may use it. On client work, that's not optional.
- Whole-project indexing
- Edits applied straight to files
- Privacy Mode
- ✓Richest context in this ranking
- ✓No more copy-paste between chat and editor
- ✓Built on VS Code, so your extensions come along
- ✗$8 Plus is Grok models only
- ✗Third-party models at API rates
- ✗You have to switch editors
If you code all day on the same project, it's the smoothest experience going. If you just want to ask questions, it's overkill. More in our Cursor review.
Gemini
Gemini has an edge the others charge more for: a very large context window on paid plans. You can hand it a big pile of files and ask targeted questions about them. That's the use developers defend most, and Google AI Plus starts at $4.99 a month.
Watch out for old tutorials. Gemini Code Assist in the IDE and Gemini CLI stopped serving personal accounts and Google AI Pro and Ultra subscribers in 2026. Google moved that work to Antigravity, its coding environment, which has a free tier with weekly limits and more room on Pro or Ultra. A Gemini CLI guide from before won't work with your personal account.
On code quality, feedback is mixed. A thread on Google's developer forum reports a severe quality regression in coding workflows, and some users say chats forget earlier than advertised. The free tier is now Flash-Lite only, with a 32,000-token context: too short for a real project.
- Google AI Plus at $4.99
- Large context on paid plans
- Antigravity for coding
- ✓Lowest paid entry price here
- ✓Handy for querying a large codebase
- ✓Google storage bundled in
- ✗Coding tools moved to Antigravity, old guides are stale
- ✗Reports of quality drops on code
- ✗Free tier limited to Flash-Lite
A solid second assistant for big code reads, rarely the first. All the plans are in our Gemini review.
Mistral Vibe (formerly Le Chat)
Mistral renamed Le Chat to Vibe in 2026 and gave it a coding mode. On the developer side it ships Vibe CLI, a terminal agent powered by Devstral, Mistral's coding model. Pro costs $14.99 a month before tax and promises all-day coding in the CLI, the IDE or on the web.
It's the cheapest full subscription in this ranking and the only one from a European company. For students, $5.99 a month is hard to beat. Devstral also comes as an open-weights model you can run yourself, a real option when code can't leave your machine.
It still trails on perceived quality, though. Feedback on Devstral mentions latency at launch, mixed views on performance and a first setup that takes time. For a hard question, most developers still go back to Claude or ChatGPT.
- European vendor
- Vibe CLI with Devstral
- Students at $5.99
- ✓$14.99 Pro undercuts Claude and ChatGPT
- ✓Open-weights coding model available
- ✓Terminal agent included
- ✗Behind on hard questions
- ✗Prices exclude tax
- ✗Devstral setup takes longer
The right call if European origin matters to you or your client, or if money is tight. For other European picks, see European AI assistants.
What each assistant does with your code
It's the question nobody asks until a client does. France's ANSSI and Germany's BSI rank code confidentiality as the top risk of AI coding assistants. Here's the setting to check, tool by tool.
GitHub Copilot: switch it off on a personal account
On Free, Pro, Pro+ and Max, interactions have been used for training since 2026 unless you disable "Allow GitHub to use my data for AI model training" in your Copilot settings. Business and Enterprise aren't affected. Do it before you open a client repo.
Cursor: Privacy Mode
On, your code and requests aren't used for training. Off, Cursor may use them. It's an account setting, not a project one, so check it on every machine.
Claude: a choice you make
On consumer plans (Free, Pro, Max), you decide whether chats and coding sessions are used for training. Opt in and they're kept for five years; opt out and it's 30 days. You can change it in privacy settings.
ChatGPT: off by default only on work plans
Training is off by default on Business, Enterprise and the API. On a personal account, turn off the model improvement setting before you paste code that isn't yours.
The simple rule for client code
No API keys, no passwords, no production config files in a chat, whatever the tool. And if the contract says code can't leave, you still have open-weights models you run yourself, such as Mistral's Devstral.
What developers wish they'd known sooner
These come from forums and from developers who use these tools every day. They save the most common time sinks.
Check every package before you install it
SecurityAn assistant can make up a library name that doesn't exist. Attackers register those names on npm or PyPI with malicious code, a trick known as slopsquatting. In one study, 43% of hallucinated packages came back every time the same prompt was rerun. Before running a suggested npm install, check the registry for creation date and downloads, and keep a lockfile.
- Hallucinated packages that repeat
- 43%
One chat per problem
CapsClaude, ChatGPT and Copilot meter by how much text gets processed, not by message count. A giant thread resends the whole history with every question. Start a new chat per bug or feature and paste only the files that matter: your allowance lasts a lot longer.
- Claude's window
- 5 hours plus weekly
Connect the repo instead of pasting
Time saverIn a Claude Project, add your GitHub repo from the knowledge panel. Only one branch's files are read, and "Sync now" refreshes after a push. Pick a clean branch without build folders so you don't fill the context with junk.
- What's read
- One branch's files
Try Copilot Free before paying for a chat
BudgetCopilot Free gives you 2,000 completions a month and limited chat, no card needed. On paid plans completions use no credits, only chat does. If you don't chat much, $10 Pro sits nicely next to a Claude or ChatGPT plan.
- Copilot Free
- 2,000 completions a month
Don't follow an old Gemini CLI tutorial
GotchaWith a personal Google account, Gemini CLI and the Gemini Code Assist extensions stopped responding in 2026. Use Antigravity and its command-line tool, which works the same way. Companies on Standard or Enterprise licenses follow a separate schedule.
- Replacement
- Antigravity
Read the model line on Cursor's pricing
GotchaCursor Plus at $8 only includes Grok models. For Claude or GPT in the editor you need Premium at $30, with third-party models at API rates. Copilot Pro+ at $39 includes premium models inside its $70 of credits.
- Cursor Plus
- $8, Grok models only
Other names you'll run into, and why they're not here
These come up in developer threads. They have strengths, but each lacks a readable price, a data guarantee or a design built for conversation.
Grok: a price you only see at checkout
No public priceGrok scores 3.8 out of 5 in our review, and its API is competitively priced. But the consumer subscription publishes no amount and no usage numbers before you pay. We can't rank it fairly against readable pricing pages.
- Score
- 3.8 out of 5
DeepSeek: good at code, data stored in China
DataDevelopers name it for low-level work and price. Its policy says prompts and uploaded files are stored in China, and a Belgian consumer group has filed a GDPR complaint. Keep it away from client code.
- Blocker
- Storage in China
Perplexity: for finding documentation
Add-onGreat for pulling up recent docs with sources, much less so for a long back-and-forth about code. A companion tool, not your main assistant.

AI chatbots for developers · FAQ
What's the best free AI for coding?
Copilot Free, if you code in VS Code or JetBrains: 2,000 completions a month and limited chat, no card required. For chatting in a browser, Claude's or ChatGPT's free tier will do in a pinch, but Gemini's free tier is limited to Flash-Lite and a 32,000-token context, too short for a real project.Is Claude or ChatGPT better for coding?
Claude for reasoning, reviewing and refactoring; ChatGPT if your assistant also has to handle images, voice and research. Both get the same score from us. The practical difference: Claude Code comes with Pro at $20, Codex comes with every ChatGPT plan, free included, with far more room on Plus at $20.Is GitHub Copilot worth it on top of a chat subscription?
Yes if you code in an editor every day. At $10 a month, Pro gives you completions that use no credits and a chat that sees your files. Many developers keep Copilot for the editor and Claude or ChatGPT for the big questions.Will my code be used to train the AI?
It depends on the setting, not the tool. On Copilot Free, Pro, Pro+ and Max, training has been on by default since 2026: turn it off in settings. In Cursor, enable Privacy Mode. With Claude it's your choice; if you opt in, retention goes to five years.Why do I hit my limit so fast?
Because most assistants meter processed text, not messages. A long thread resends its whole history with every question, and with Claude, Claude Code draws on the same allowance as chat. Use one chat per problem and paste only the files you need.Which AI is best for learning to code?
ChatGPT or Claude in the browser, because they explain line by line and handle beginner questions without judgment. Early on, skip editors that edit your files for you: you learn less. Students can get Mistral Vibe Pro for $5.99 a month.Can I use an AI coding assistant without sending code online?
Yes, with an open-weights model you run yourself. Mistral's Devstral has a small version that runs on consumer hardware. The hosted assistants in this ranking all send your code to their servers.Is Gemini CLI still free?
Not with a personal Google account: Gemini CLI and the Gemini Code Assist extensions stopped serving individual accounts and Google AI Pro and Ultra subscribers in 2026. Google points you to Antigravity, free with weekly limits and roomier with a Google AI plan.
