Why Mashbyte
Presenting to a room is broken in three familiar ways.
Mashbyte was built to fix the parts of a live presentation that projectors and video calls get wrong.
The back row can’t read your slides.
Small text, washed-out projectors and long rooms mean half the audience is squinting.
Every participant gets the slide on their own screen, rendered sharp, and can pinch to zoom.
Screen sharing is a blurry video.
Compressed streams lag seconds behind and fall apart on weak connections.
Mashbyte sends the slides and your ink as data, not video, so they stay crisp and in sync.
Only the loudest people speak up.
Raising a hand in a big room is intimidating, so most questions never get asked.
Polls and Q&A let everyone answer or ask from their device, without taking the floor.
Features
Everything you need to run an interactive session.
Six capabilities, built to work together from the first slide to the last question.
Real-time slide sync
Upload a PDF and present it. Every slide change reaches each connected device the moment you make it.
- Up to 150 devices in one session
- Participants can pinch-zoom their own view
- Presenter zoom can follow on every screen
Live drawing & whiteboard
Annotate on top of any slide, or switch to a blank whiteboard. Strokes stream as you draw them.
- Pen, highlighter and text in 5 sizes
- 5 colours, undo and clear
- Late joiners see ink already on the slide
Polls & quizzes
Attach a question after any slide in the editor, then launch it live with one click.
- Multiple choice with a correct answer to reveal
- Open text shown as a word cloud or list
- Rating on a 1–5 or 1–10 scale
Audience Q&A
Participants send questions from their device. They queue in a panel you open when you’re ready.
- Short questions, up to 70 characters
- Shows who asked and when
- Nobody has to interrupt the talk

Comparison
Why not just share your screen?
Screen sharing sends a video of your slides. Mashbyte sends the slides themselves, rendered on every device.
Security & reliability
Serious about the details.
Built so presenters can rely on it in front of a room, and participants never hand over personal data.
No participant accounts
Participants join with a code and a display name. No email, no password, no profile.
Credentials stored hashed
Presenter passwords and guest PINs are hashed, never stored in plain text.
Verified presenter accounts
Presenter accounts are email-verified before they can sign in.
Scoped guest access
Guest presenters can only reach the one presentation they were invited to.
Reconnects gracefully
If the presenter drops, the session waits 3 minutes for them to come back before ending.
Light on bandwidth
Slide changes and ink travel as small data updates, not as a video stream.
FAQ
