About CodeTrain

CodeTrain is a Socratic AI coding tutor: it asks questions, reviews what you write, and runs your tests, but never writes the code for you. Free to start. Two steps, about a minute, and the first one is going to catch you. The tutor's replies are pre-recorded, so it knows the handful of ways this lesson usually goes wrong. The real one reads whatever you actually wrote, and it is free for ten lessons a month.

About Epho

epho runs claude code, codex, or opencode in the cloud. POST a message, stream back the work. no sdk, no daemon, no infra on your side. one request boots a fresh cloud environment with the harness you picked, clones your repos into it, connects your tools, hands it your prompt, and pipes everything back as it happens. sse streams back the whole run, tool calls, edits, the final answer. a chat is a durable conversation with a sandbox attached.
