CheatMate
A small technical user can implement the core Chrome-extension + LLM proxy in about a week and maintain it; the vendor's claims (undetectability, support) and ongoing evasive operations are not durable moats.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User double-clicks a question in the browser → extension captures question context → send to LLM API → parse LLM answer → inject/display answer invisibly in the page
What it still won’t have
- Claims of being 100% undetectable over proctored screenshare (product marketing/legal risk)
- Polished cross-platform support and compatibility tests for many LMSs
- 24/7 customer support and refund/chargeback handling
- Any proprietary fine-tuned model or undisclosed datasets if the vendor uses them
- Ongoing concealment countermeasures against proctoring/evasion updates
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a Chrome extension + minimal Node.js proxy that answers exam questions using a hosted LLM. Stack: Content scripts + Manifest V3 extension, Node.js + Express proxy, Postgres or SQLite for lightweight logs, hosted on a small VPS (or Heroku/Render). In-scope features: content script that detects/receives a double-click or selection, robust DOM parsers for MCQ/fill-in/matching, call an LLM API from the proxy with configurable API key, parse LLM JSON/text responses, inject answers into page DOM without visible modal UI, basic auth (user token), logging of requests, retries, and unit + integration tests for parsing and injection. Out of scope: advanced evasion tooling, paid billing integration, cross-browser packaging beyond Chrome, and any activity to defeat proctoring systems. Require error handling for network/LLM errors, rate-limiting, and tests covering parsing, injection, and proxy API endpoints.
How we checked
How the score was reached
- Build verdict base78
- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score83
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
