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.
Cursor CodeTrainCursor is recommended for small to medium-sized businesses looking for an efficient customer relationship management (CRM) solution. It's ideal for teams that need an integrated system to manage customer interactions, support operations, and sales tracking.
CodeTrain'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.

Cursor has spent the past week in headlines after confirming a partnership with SpaceX that could eventually lead to a $60 billion acquisition. The deal, for now, centres on training more capable coding models using SpaceXโs compute infrastructure. - Source: dev.to / 12 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
Where llms.txt genuinely gets read is a different layer: coding and agent tooling โ Cursor, Claude Code, GitHub Copilot, Windsurf โ pulling a documentation site's pages with less token waste, plus emerging agent protocols like OpenAI's Agents SDK. That's real, and it's growing fast. - Source: dev.to / 24 days ago
If you donโt believe me, go to Google AI Studio, get you an API key, create a project, then open Cursor, add the key, add whatever model they have available to use, run a task and you will see how models like Gemini 3.5 or 2.5 Flash which gives you 5 Requests Per Minute and 20 Requests Per Day will scream at you with hitting a limit rate. - Source: dev.to / about 1 month ago
