Programmatic SSP that helps publishers earn more from every impression
Runs multiple demand sources in a single simultaneous auction to increase competition on each impression.
Supports the VAST standard so video and in-stream inventory can be monetized alongside display.
Connects through the OpenRTB protocol for standardized real-time bidding with multiple demand partners.
Live dashboards track CPM, fill rate and revenue so publishers can spot and act on trends immediately.

Handwritten notes, PDF markup, and AI study tools on one canvas
Low-latency ink with palm rejection, cross-out to erase, and handwriting-to-text conversion keeps writing close to pen on paper.
Import contracts, papers, or textbooks and mark them up by hand, with searchable annotations and clean exports.
Search across typed text, handwriting, and sketches, and turn notes into summaries, mind maps, or structured plans.
Work together in shared notebooks, documents, and whiteboards simultaneously, without version conflicts or file ping-pong.
