How PreceptorMD checks its answers before you see them

An AI answer that sounds right but is wrong is worse than no answer, especially a week before finals. So PreceptorMD is built to show its work, and to stay quiet when it can't.

Every fact quotes a slide

When you ask a question, PreceptorMD first finds the slides in your decks that are most relevant to it. The answer is written only from those slides, and each fact in it has to carry a short quote from the slide it came from, with the deck and slide number.

You can tap any source to open the slide and read the line yourself.

The quote is checked before you see it

Before an answer is shown, a separate check runs on every quote:

1. The quote must appear on the slide it cites. Small differences in spacing and capitals are allowed; changed words are not.
2. The quote must be 25 words or fewer, so you see the exact line and not a paraphrase.
3. Any number in the quote, such as a dose, an age or a cut-off, must appear on the slide.

A fact whose quote fails the check is dropped from the answer. If too little survives, you get "Not found in your materials" instead.

"Not found" is a feature. It tells you your slides don't cover the question, which is useful to know before an exam.

When your slides don't cover it

After a "Not found", you can choose to search a short list of published sources: the National Library of Medicine's services (PubMed, NCBI Bookshelf, MedlinePlus) and Wikipedia. Those answers are clearly labelled as outside your slides, and their quotes are checked against the source text in the same way.

Guidelines come first

Lecture slides and national guidelines sometimes disagree, usually because one of them is older. When a guideline deck shared by your school, such as the Ghana Standard Treatment Guidelines, the Essential Medicines List or a Ministry of Health programme guideline, covers dosing or management, it outranks lecture slides. If the two disagree, the answer says so and shows both sources. Conflicts are flagged, never hidden.

Questions with one defensible answer

Exam-style questions go through their own check: each one must have exactly one defensible answer, and every option gets an explanation tied to your slides. Questions that fail are thrown away before you see them.

When something is still wrong

Your slides can contain mistakes, and so can PreceptorMD. Every answer, question and card has a report button. When enough students report the same item, it is taken out of circulation until it is reviewed, and coordinators can see what was reported.

What this means for lecturers

Answers point to your slides, not to the internet. A lecturer can check any answer in seconds by opening the slide it quotes. PreceptorMD works from what you teach and sends students back to it.

PreceptorMD is a study tool only. Confirm anything you intend to act on against current guidelines and your supervisors.
