Who it is for
Students turning lecture notes and readings into self-testing material ahead of exams.
Overview
What Drill does
Drill treats revision as verification. Each card holds a Truth alongside plausible Traps, so recalling the right answer means rejecting distractors that look reasonable rather than picking out an obvious odd one.
Cards group into Decks and carry Tags. Material can then be filtered by how well it is known, using the states Untested, Weak, Unproven, and Mastered, which turns a pile of course notes into a queue ordered by what still needs work.
The case it is built around is converting lecture and reading material into testable content before an exam. Drill is the work of an independent developer, Jordan Martinelli.
What stands out
Cards carry deliberately plausible wrong answers, and four status labels sort material by how well it has been proven.

Where Drill is listed
Drill is listed in the ChatGPT apps directory only. Jordan Martinelli has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
