Bella-Presenter

Bella Presenter is a fast, native dual-screen presenter for PDF slides, made for decks exported from Typst or LaTeX/Beamer.

Open a PDF and you get two windows. The presenter window shows the current slide, a preview of the next one, your speaker notes, a talk timer with clock, and a thumbnail strip of all slides. The audience window shows only the slide, fullscreen on the projector or second screen.

Decks with notes on a second screen (a double-width page with the notes on the right half, as Beamer and Typst produce them) are detected and split automatically. Plain decks just work.

Features:

• Presenter and audience windows, second-screen aware (F5 to start)
• Speaker notes, next-slide preview, talk timer and clock
• Laser pointer and freehand drawing, mirrored live on the audience screen
• Zoom and pan at the cursor on either window
• Webcam overlay in a corner of the audience screen, with blurred or removed background (runs locally, nothing uploaded)
• Clickable PDF links: internal links jump to the slide, web and mail links open
• Adaptive, resizable layouts, light/dark theme
• Recent files and resume at the last slide
• Stays instant on 300+ page decks thanks to lazy rendering, texture cache and prefetch
• Built-in updater
