$99.99 one time. No subscriptions.
Operator Dashboard
All your scripts in one clean, high-contrast dashboard, with options to share, import, or create a new one.
Script Editor
Write and edit your script with inline slide cues. Word count and estimated runtime update as you type.
Operator Control
Run the show from the operator window: live speed control with bump keys and mouse control, and even control your presentation right from your script.
Talent Window
The output your talent sees: full screen, high contrast, and a clear reading line. Smooth scrolling, and it can be controlled natively right from ProducerDash.
Everything you need to stay on script.
Live Teleprompter
A full-screen display with nothing but your text. Clean, high contrast, readable from across the stage. Any device on your local network can also stream the prompter in a browser.
Script Sharing Between Devices
Send a script straight to any other Mac running Lectrin on the same network. Click Send to another Mac on the script, pick the Mac, and it lands in their library. No exporting files or emailing them around.
USB Remote Compatibility
Plug in any standard USB presentation remote and map its keys to the controls you need: play or stop, speed up, slow down, jump back, and back to top. Run your script without touching your Mac.
Inline Slide Cues
Drop slide cues right into your script. When the prompter reaches a cue, Lectrin advances your slide for you, either directly in ProPresenter over the network or as a MIDI trigger, so your slides follow the script.
Import Word and PDF Documents
Point Import at a Word (.docx) or PDF file and Lectrin builds a brand new script from it, carrying your highlighting and bold across as on screen emphasis. Word files convert cleanly, PDFs are best effort, and it all runs on your Mac.
