Demist for pharmacy students
Pharmacy lectures move between chemistry, physiology and clinical practice in the same hour, and the drug names alone are a second vocabulary. Stop to look one up and the mechanism that followed it has gone.
What it does during a pharmacy lecture
Demist transcribes as your lecturer speaks, picks out the terms you are unlikely to know at your year of study, and puts a one-sentence explanation on screen while they are still talking. You keep listening instead of writing down a word to look up later.
Afterwards you have the full transcript, a glossary of every term that came up, a summary, and flashcards scheduled by spaced repetition so you revise something shortly before you would have forgotten it.
The kind of pharmacy terminology it explains
Bioavailability
The proportion of a dose that reaches the general circulation unchanged. An intravenous dose is 100% bioavailable; an oral one is usually less.
First-pass metabolism
The breakdown of a drug by the gut wall and liver after it is swallowed and before it reaches the rest of the body, which lowers how much is available.
Half-life
The time it takes for the concentration of a drug in the blood to fall by half.
Therapeutic index
The ratio between the dose that causes harm and the dose that has the intended effect. A narrow therapeutic index means little margin for error.
Agonist
A drug that binds to a receptor and activates it, producing a response like the body's own signalling molecule would.
Explanations are written for your year of study and the subject you set up, so a first year and a finalist get different levels of detail for the same word.
For understanding lectures, not for dosing
Demist explains what a term means so you can follow the lecture. It is not a prescribing reference and its explanations are AI-generated, so never use them for doses, interactions or anything clinical. Your course will point you to the proper references for that.
Where your lecture audio goes
In the Windows app, live recording is transcribed, and its terms detected and explained, by AI models running on your own machine, so the audio of a live lecture never leaves your computer. Your transcript and glossary sync to your account so you can see them on the web and keep your history if you reinstall.
The browser version works differently: it sends the audio to our server to be transcribed, and sends the terms it picks out to be explained. So does uploading a recording, in any version. The privacy policy sets out exactly what goes where.
What it costs
Live explanations, translation, your glossary and your flashcards are free, with no advertising. Recording is free and unlimited in the Windows app; in the browser, free accounts get three recordings. Free accounts keep lecture history for seven days. Demist Pro keeps your whole term, records in the browser with no limit, and adds unlimited summaries and Anki export for £4.99 a month. New accounts get Pro free for their first 30 days, with no card.
Built for students who find lectures harder to follow
Demist exists for pharmacy students with a hearing impairment, with dyslexia, who find holding attention difficult, or who are studying in English as a second language. If that is you, it is worth trying for one lecture.
