What is the best AI for coding, data and technical work?

There is no single answer, which is why this page lists 13 of them rather than one. 6 are built specifically for this kind of work; the rest do it well without it being their focus. Start with a free one and change your mind cheaply.

Which of these are free?

9 of the 13 have a genuine free plan you can sign up for today: ChatGPT, Claude, Cursor, Lovable, Replit, Codestral, Gemini Code Assist, Hugging Face, LangChain / LangSmith. Free here means a real free tier, not a trial that expires.

How were these chosen?

Every AI product we know of that fits this category is listed, whether or not there is any money in it for us. Ordering is by how well a tool fits the task and whether it has a free plan. Placement is not for sale.

How current are the prices?

Prices were last verified on 31 August 2026. They change often, so confirm on the provider's own pricing page before you spend anything.

Best AI for Coding

Coding, Data & Technical Work

Programming, debugging, data analysis, spreadsheets, math, engineering, technical research. Typical asks: "Fix this bug." "Clean up this spreadsheet and chart it."

ChatGPT OpenAI Free plan Built for this

Good for
Best general option for explaining unfamiliar code, debugging a single file, or analysing a spreadsheet with real Python behind it.

Watch out
Weaker than a dedicated editor once a project spans many files.

Free version
Yes — Free tier, slower models at busy times
Paid plans
- Go — $8/month
- Plus — $20/month
- Pro — $200/month
- Business — $25/person/month on annual billing, $30 month to month
Open ChatGPT ↗
Claude Anthropic Free plan Built for this

Good for
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.

Watch out
The chat window has no access to your project. For multi-file work you need the agent below or a dedicated editor.

Free version
Yes — Free tier with daily caps
Paid plans
- Pro — $20/month
- Max 5x — $100/month
- Max 20x — $200/month
- Team — $25/person/month on annual billing, $30 month to month
Open Claude ↗
Cursor Anysphere (Cursor) Free plan Built for this

Good for
The editor most professional developers have converged on. Understands a whole codebase, not just the open file.

Watch out
A SpaceX subsidiary since the June 2026 acquisition, which matters if vendor independence does.

Free version
Yes — Hobby plan, limited credits
Paid plans
- Pro — $20/month
- Pro+ — $60/month
- Ultra — $200/month
- Teams — $40/person/month
Open Cursor ↗
Lovable Lovable Free plan Built for this

Good for
Built for people who cannot code. Describe an app in plain language and get something deployed.

Watch out
Fine for prototypes and internal tools. Anything you run as a business needs a developer to review it, especially the security.

Free version
Yes — Free tier, a few credits daily

Paid plans
Not verified — check Lovable pricing
Open Lovable ↗
Replit Replit Free plan Built for this

Good for
Everything in the browser — write, run and deploy with nothing installed. The best fit for learning and for coursework.

Watch out
Free tier limits compute and keeps projects public. Check that before putting graded work in it.

Free version
Yes — Free Starter, projects are public

Paid plans
Not verified — check Replit pricing
Open Replit ↗
Claude Code Anthropic Paid only Built for this

Good for
Runs in the terminal across whole repositories — refactors, test suites, multi-file changes.

Watch out
Consumes usage quickly on long agentic runs. Assess it on your own codebase.

Free version
No — paid from the start
Paid plans
- Requires Claude Max 5x — $100/month
- Moved off the $20 Pro plan in mid-2026
Open Claude Code ↗
Codestral Mistral AI Free plan Strong fit

Good for
Open-weight code model you can run locally. The practical choice when code cannot leave your machine.

Watch out
Local models trail hosted frontier models. You trade capability for control.

Free version
Yes — Open weights, free to run yourself
Paid plans
- Metered API if you would rather not host it
Open Codestral ↗
Gemini Code Assist Google DeepMind Free plan Strong fit

Good for
Unusually generous free tier for individuals, and it plugs into standard IDEs rather than requiring a new one.

Watch out
Less capable at whole-repository reasoning than the purpose-built agents.

Free version
Yes — Free for individuals, unusually generous

Paid plans
Not verified — check Gemini Code Assist pricing
Open Gemini Code Assist ↗
Hugging Face Hugging Face Free plan Strong fit

Good for
Where open models actually live, with download counts showing what people use rather than what is marketed.

Watch out
A repository, not a tool. You still need somewhere to run what you download.

Free version
Yes — Free account, unlimited public repos

Paid plans
Not verified — check Hugging Face pricing
Open Hugging Face ↗
LangChain / LangSmith LangChain Free plan Strong fit

Good for
The standard framework for wiring a model to your own data, with tracing so you can see why it answered as it did.

Watch out
A developer library, not an application.

Free version
Yes — Open-source framework; LangSmith has a free tier

Paid plans
Not verified — check LangChain / LangSmith pricing
Open LangChain / LangSmith ↗
Databricks Databricks Paid only Strong fit

Good for
Where serious data work happens — governed data, notebooks and model serving in one place.

Watch out
Organisation-scale tooling. Overkill for a spreadsheet.

Free version
No — no usable free tier

Paid plans
Not verified — check Databricks pricing
Open Databricks ↗
Devin Cognition Paid only Strong fit

Good for
Autonomous agent that takes a ticket and works it to completion. Sold to engineering organisations.

Watch out
Enterprise contracts. Autonomy means less visibility into what changed — review discipline matters more, not less.

Free version
No — paid from the start
Paid plans
- Enterprise contract, priced with the vendor
Open Devin ↗
Poolside Poolside Paid only Works, not its focus

Good for
Trains its own code models and deploys inside customer environments, including air-gapped ones.

Watch out
Enterprise only. Nothing individual to evaluate.

Free version
No — paid from the start
Paid plans
- Enterprise, deployed into your own environment
