Voice Lessons
A tutor that talks you through your own study material.
A Live Voice Lesson is 15 minutes of spoken teaching from the pages you added. Interrupt it, ask it to say it another way, or ask it to draw the thing.

3 of 5 · Why the oral dose is larger
Listening
A tablet has to go through the gut wall and then straight through the liver before any of it reaches the rest of you. The liver takes a cut on the way past, and what is left is the bioavailable fraction.
YouSo an injection skips all of that?
It does. Straight into the blood, nothing taken off, which is why the oral dose of the same drug is the larger of the two.
How it works
- 1
Pick a concept
Open a concept in your module and start a Lesson on it. It runs for about 15 minutes.
- 2
Talk it through
The tutor teaches from the passages behind the concept. Answer, ask, or interrupt it, out loud.
- 3
Keep the record
When it ends, SymbioLearn writes down what was actually covered, and Today uses that to decide what comes back.
It teaches from your pages
Each Lesson is on one concept from your module, taught from the passages behind it in your Sources. The passage it is citing opens in a small panel over the Lesson, so you can read the line it is explaining without stopping the conversation. With a concept you have not studied yet, it teaches first and checks lightly.
It brings in its own examples to make an idea concrete: a real case where it is sure of one, and an imagined one where it is not.
It draws when words are slow
When a curve or a diagram explains it faster than words, the tutor draws it beside what it is saying, and where moving something helps, you can move it. The drawing stays with the Lesson, so it is still there when you come back to it.

Two classes can sit the same paper, average the same mark, and feel nothing alike. Widen the spread and watch what stays inside the band.
Same average, different spread
Drag the spread. About 68% of the class is always inside one deviation.
It writes down what was covered
When the Lesson ends, SymbioLearn reads the transcript, writes down which parts of the concept were actually covered, and keeps that record. Today uses it, with your quizzes and flashcards, to decide which concepts come back and when.
What happens to what you say
To run a Lesson, your voice goes to our AI provider, whose paid API terms say it is not used to train their models. SymbioLearn keeps the Lesson as a written transcript and a summary, so you can look back at it, and does not keep the audio. Deleting a module deletes its Lessons, and deleting your account deletes everything. Privacy Policy
Minutes
Lessons use minutes while the conversation is connected, rounded up to the nearest minute.

When minutes run out, Lessons stop starting. Concepts, quizzes, flashcards and Today carry on.
Questions
How long is a Lesson?
About 15 minutes. A concept that needs longer carries on in the next Lesson, which picks up where this one stopped.
What do I need?
A microphone and somewhere quiet. It runs in your browser, on a laptop or a phone.
Can I interrupt it?
Yes, whenever you want, or ask it to explain something a different way.
What does it teach from?
The passages behind the concept in your module's Sources. It adds its own examples to make an idea concrete, and the passage it is teaching from is there to check.
