Pluma is a fresh take on an impression board app, connecting to the boards you may already own. It offers dramatically better text recognition and powerful features, whilst simultaneously being dramatically better designed. Together, it's more powerful yet easier to use than the core apps offered by most impression boards. It also connects with my suite of apps as well as many third party apps, devices and services, enabling brand new routines never before possible. Features include: ** Advanced AI Text and Drawing Recognition Pluma AI offers best-in-class AI recognition, which can detect handwritten text AND drawings, in any orientation. ** Multiple Board support (beta) Receive peeks from up to four impression devices simultaneously! ** Earworm Integration Make a prediction in the YouTube app on your spectator's phone. Then, have your spectator write the name of any song on the impression pad. Pluma AI integrates with Earworm to do the rest: they just turn up the volume on the spectator's phone to find the chosen song playing in their YouTube app! ** Supports Multiple Board Types Currently supports boards from Lumen Pro, Iarvel, Pitata, Ultra Sharpie, Ultra Sharpie Neo, Oblivious Engage, PMA and Wave, with more brands added over time. ** Offline Text Recognition For times when there's no signal, Pluma includes excellent realtime offline AI text recognition at no extra charge. ** PeekSmith Integration Pluma connects directly to PeekSmith, letting you get your peek during performance. ** Lumen Duo Integration Pluma also connects directly to Lumen Duo, letting you get your peek even more covertly. ** Earpiece Support Pluma can automatically speak the recognised text to your covert earpiece. ** Apple Watch App Get your peek on the custom built Apple Watch app, with optional covert mode. ** Notifications Compatible with any Bluetooth peek device that supports third party notifications. ** Bridge & Inject Integration Automatically send your peek to the Bridge or Inject apps, which integrates Pluma with many magic apps, services and devices. ** Powerful Features, Easy To Use Pluma brings multiple, advanced innovations from my previous apps (such as Touch To Peek and app integration via polling), whilst simultaneously built to be easy to use and understand. ** Much More Pluma offers features to automatically scale, automatically send peek data and automatically clear. It offers per-board calibration settings, AI optimisation settings, intuitive history features, auto-save to photos, board battery indicatiors, and much, much more. Notes A physical impression board is required. Pluma currently supports Iarvel and Pitata boards, with more brands to be added over time. Pluma works in multiple languages, including Arabic, Chinese (Simplified), Chinese (Traditional), Czech, Danish, Dutch, English, French, German, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese Online AI recognition features require the use of in-app credits (with some provided on purchase), or you can provide your own API key. Offline AI text recognition is included for free. No yearly subscription or device fee needed for either Pluma is offered for entertainment purposes only.
