1. CodeTrain
CodeTrain runs a Socratic tutor against your actual repo: it breaks work into small steps, makes developers type every line themselves, and reviews what they wrote without handing over the answer. The local-first free tier keeps code on the machine; the managed tutor sends submitted snippets. A lightweight profile tracks gaps and resurfaces them later through spaced repetition, so a developer who struggled with your auth pattern sees it again before it bites them in production. The team dashboard lets a manager see finished lessons and concept coverage per developer. The ceiling arrives quickly for teams that need structured, multi-week curricula with custom assessments beyond what the Socratic loop can generate.

2. AI Pair Programmer for Emacs
CodeTutor is a free, open-source Emacs package that watches your file saves, gathers project context, and routes the diff to a local AI backend configured to respond like a senior engineer talking you through your own decision — not handing you the answer. The boundary is explicit by design: it will explain the concept, show a compact illustrative snippet, and recommend a next step, but it does not write into your files, produce patches, or hand you a paste-ready implementation. Architecture notes accumulate automatically in a `.codetutor/ARCHITECTURE.md` file as you work. This is early-stage, single-maintainer software with two commits on record — you are not buying into a mature product.

3. Sotto
The scraped page content provided does not match the tool described in the structured data — the page describes Spotter, a travel photo-identification app, not a coding interview assistant. No factual claims about {{input.name}}'s features, workflow, transcription behavior, or hint delivery can be sourced from the available page content. Writing production-accurate copy without a grounded source risks asserting capabilities that do not exist or misrepresenting the product. To produce publication-ready listing content, a correctly scraped vendor page for {{input.name}} by Sotto is required.
