CodeTrain is a hands-on AI trainer for developers.
Instead of writing code for you, it turns any question, repo context, or onboarding task into a short lesson on your own codebase: two to six small steps, each one typed by you in an editor with an instant run/test loop. The tutor grades every step, asks Socratic questions when you miss, and shrinks the step when you're stuck.
Pro adds repo mode with a single reviewable patch-back of the code you wrote; Team adds ramp dashboards and onboarding journeys. Free tier runs in the browser, ten sessions a month, no card. Github link to the free skill is provided.

CodeTrainCodeTrain's answer:
CodeTrain is an AI coding tutor that never writes the code for you, and that refusal is built into the architecture rather than a system prompt. It plans a short lesson from your own codebase (in repo mode), sets up 2 to 6 tiny steps, runs the code you type, and grades every step against explicit criteria. When you get stuck it shrinks the step or sharpens the hint. There is no code-generation path to talk it out of, which is the part every chat-based tutor gets wrong.
CodeTrain's answer:
Coding assistants like Copilot and Cursor are built to produce code. CodeTrain is built to produce engineers who actually understand the code. Learning platforms like Codecademy teach generic curriculum and measure completion, but they never touch the codebase you actually work in. Chat tutors hand you the answer if you ask persistently enough. CodeTrain grades what you typed, on your own repo, and the answer never comes for free. Use it alongside your assistant, not instead of it.
CodeTrain's answer:
Developers who use AI assistants daily and can feel their understanding of their own systems slipping. Junior engineers who ship AI-written diffs they couldn't rewrite. And engineering managers who want new hires ramped on the team's real codebase, with a dashboard showing who's progressing, who's over-relying on skips, and what each seat costs.
CodeTrain's answer:
I was building InferHaven, a privacy-first AI dev workspace company, and caught myself approving AI-written diffs I could not have rewritten from scratch. InferHaven exists so teams don't hand their code to vendors; CodeTrain extends the same instinct to the second thing quietly leaving the building, the skill in engineers' heads. So I built the opposite of an assistant: a tutor that plans, runs, and grades, but never types your solution. It launched publicly in Julyย 2026.
CodeTrain's answer:
FastAPI and PostgreSQL on the backend, primarily Claude models for tutoring, CodeMirror for the editor, and Pyodide so free-tier Python and JavaScript run entirely in the learner's browser. Shell and other runtimes execute in isolated server sandboxes. Clerk handles auth, Stripe handles billing, and bring-your-own-key support covers Anthropic, OpenRouter, Bedrock, Vertex, and Ollama.
CodeTrain's answer:
Too new to drop names honestly: CodeTrain launched publicly in Julyย 2026. Early users are individual developers on the free and Pro tiers, with the first team pilots in progress. If a public logo matters to you, check back in a quarter.

Visual Studio Code, a code editor created by Microsoft, was first introduced on April 29, 2015, at the Build conference. - Source: dev.to / 9 days ago
The step up from there is an editor with a built-in agent like Cursor, Google Antigravity, Windsurf, or VS Code with a coding extension. These are code editors with an AI agent living inside them, and the difference is the responsible party for getting things from place to place. Instead of the software creator shuttling code between windows, the AI agent edits the project files directly and runs the GitHub and... - Source: dev.to / 24 days ago
For IDE-heavy teams, BYOK (bring your own key) can be interesting, no matter whether you live in WebStorm or VS Code. On the JetBrains side, the JetBrains AI plans and Junie BYOK docs allow it, and most VS Code AI extensions offer the same idea: keep the IDE, connect provider keys, pay the provider. - Source: dev.to / about 1 month ago
Option 1: Raw editing in IDE. You open the .md file in VS Code or whatever you use. Syntax highlighting shows you the structure. Maybe you toggle a preview pane. This works for quick edits but becomes painful for anything involving tables, diagrams, or complex formatting. - Source: dev.to / about 2 months ago
You'll need Python 3.8+ and pip for the quickstart, with venv recommended for isolation. Install the requests library for HTTP calls. VS Code with the Python extension works well as an editor, though PyCharm or Sublime Text work equally well. You'll also need a free Foxit developer account. - Source: dev.to / about 2 months ago
