The AI tutor that draws anatomy and physiology for you.
Ask about any structure, pathway or mechanism. Biro draws a labelled diagram, explains it step by step as it draws, and ends with a quick question so you know it stuck.
Labelled diagrams for the things you have to memorise.
out to the body Left atrium Left ventricle
thickest wall Right atrium
Anatomy
“Label the chambers and valves of the heart and trace the blood flow.” Biro draws it, names every part, and points arrows the right way.
Physiology
“Walk me through the renin–angiotensin–aldosterone system.” Each step is drawn as a pathway, in order, with what triggers the next.
Mechanisms
“Why does the left ventricle have the thickest wall?” You get the reason, the picture that shows it, and a one-line takeaway.
Your lecture notes
Upload a PDF or a photo of your notes. Biro pulls out what matters and redraws it as a diagram you can study from.
Biro draws more than anatomy: physics problems, PDFs and plans too. See everything the AI tutor draws.
Questions from med students
Is Biro a good AI tutor for medical school?
Biro is built for students who learn from pictures: it answers anatomy, physiology and mechanism questions by drawing labelled diagrams and explaining each step, instead of returning a wall of text.
Where do the anatomy pictures come from?
Reference images come from openly licensed sources such as Servier Medical Art and Wikimedia Commons, with Biro's own labels and arrows drawn on top. Processes and pathways are drawn fresh for your question.
Can I use it with my own lecture slides?
Yes. Add a PDF or a photo of your notes and Biro turns the key ideas into diagrams, summaries and practice questions.
How much does it cost?
There is a free plan with 70 typed answers a day. Pro is $12 a month and adds voice, so you can talk it through out loud.
