Convert Your Notes to Audio and
Listen Anywhere
Convert your study notes, PDFs, or any text into clear audio. Study while commuting, at the gym, or any time you cannot look at a screen. Free to try.
Three steps, then you're studying
Add your study content
Paste your notes, a summary you have generated, key points you have compiled, or any text you want to review as audio. A particularly effective workflow: generate a summary of a long lecture or textbook chapter with the AI Summarizer, then convert that summary to audio. You get through the essential content of a 2-hour lecture as a 10-minute audio clip you can listen to on the go.
The AI converts to audio
The text is converted to natural-sounding spoken audio. You choose from several voice options and set the playback speed. The voices are clear and comfortable for extended listening — not the robotic TTS of older tools, but genuinely natural-sounding speech.
Listen anywhere, any time
Play it in the app on any device. Or download the audio file and listen offline — useful for commutes with patchy mobile data or for saving content to listen to later. Adjust the speed as needed: 1x for new material, 1.25x or 1.5x for content you have already reviewed once.
Features that matter
Natural-Sounding Voices
The voices are a meaningful step above traditional text-to-speech. They are clear, natural in pacing, and easy to listen to for extended periods. You stop noticing the voice quickly and can focus on the content.
Adjustable Playback Speed
1x for new material you are learning for the first time. 1.25x or 1.5x for content you have already covered and are reinforcing. The ability to speed up for familiar content significantly increases how much you can cover per hour.
Multiple Voice Options
Choose from different voices to find one you find comfortable for extended listening. Personal preference matters here — the voice you find natural to follow is the one that will work best for long sessions.
Pairs With the Summarizer
Generate a summary of a long PDF or YouTube lecture. Convert the summary to audio. Get through the key content of a 3-hour lecture in 10 minutes of listening. This combination is one of the most time-efficient study workflows available.
Download for Offline Use
Download your audio as an MP3 file and listen without internet. Useful for underground commutes, areas with poor connectivity, and for saving sessions to revisit later.
Flashcard Audio Mode
Convert your flashcard content to an audio quiz format — hear the question, pause to recall the answer, then hear the answer. Self-testing without looking at a screen.
The Problem
Your commute is wasted study time
Think about the time in your day when you are not in front of a book or a screen but your attention is relatively free. The 40-minute commute. The walk between classes. The time at the gym. Doing household chores. These are hours that disappear completely from most students' study time because studying, in the conventional sense, requires looking at a page or screen.
Text to speech for studying changes this. Convert your notes, summaries, or any study material to clear, natural-sounding audio. Play it during your commute. Listen while you walk. Review key content in the hours that would otherwise go completely unused.
This is not a replacement for focused study. Reading carefully, reviewing flashcards, working through practice problems — these require your full attention and cannot be replaced by passive listening. But audio review is an effective way to reinforce content you have already studied, to expose yourself to material a second or third time in contexts where sitting at a desk is not possible, and to make useful progress in the gaps between formal study sessions.
Use Cases
Where audio study actually works
The commute
For students who spend 45 minutes or more commuting daily, this is one of the most valuable use cases. Instead of scrolling through a phone, you are going over your notes. A half-hour commute each way is an hour of audio study per day — which adds up to significant additional review over the weeks before an exam.
Walking
Many people find that their mind is more alert and receptive when they are moving. Listening to notes while walking rather than sitting stationary is a different cognitive experience for many people, and some content gets absorbed better this way.
Gym time
If you spend an hour at the gym regularly, that is an hour that currently has audio going in but no study content. Replacing music with your study notes some of the time — particularly for content you are revising rather than learning for the first time — is a reasonable exchange.
Pre-sleep review
There is some evidence that reviewing material before sleep can improve consolidation. Listening to a quiet audio summary of the day's notes while lying in bed is a lower-stimulation alternative to reading from a screen.
Visual fatigue days
After a full day of screen time in lectures, reading sessions, and practice exams, further reading is genuinely fatiguing in a way that listening is not. Audio review on those days lets you get revision in without additional visual strain.

Frequently asked questions
How does text to speech for studying work?
You paste your study notes or any text, choose a voice and speed setting, and the AI converts it to spoken audio. Play it immediately in the app or download the audio file to listen offline.
How natural do the voices sound?
Significantly better than traditional TTS tools. The voices are clear and naturally paced, comfortable for extended listening. They are not indistinguishable from a human speaker but they are good enough that you stop consciously noticing the voice and can focus on the content.
Can I use this with my AI summaries?
Yes. This is one of the most effective workflows on the platform. Summarize a long lecture or PDF with the AI Summarizer, then convert that summary to audio. You get through the essential content of a 2-hour lecture in under 10 minutes of listening.
Is it free?
Free accounts get a limited number of TTS conversions per month included in their 20 starting credits. Pro subscribers at 3.99 dollars per month get unrestricted access.
Can I download the audio?
Yes. Download your converted audio as an MP3 file and listen offline. Useful for commutes with no internet, or for saving audio sessions to come back to.
What is the maximum amount of text I can convert at once?
There is a character limit per conversion. For longer content, split your notes into sections. You can convert multiple sections sequentially and combine the audio files.
Is this useful for students with dyslexia?
Yes. Text-to-speech tools are among the most practically useful accessibility tools for students with dyslexia, and the ability to listen to your own study notes — rather than only generic audiobooks — is particularly valuable for exam-specific preparation.
Can I control the playback speed?
Yes. Normal speed for new material. Faster for familiar content. Most students find 1.25x or 1.5x very comfortable once they have adjusted, and the increased speed allows significantly more review time per hour.
