AI SQL optimizer and database performance monitor for PostgreSQL and MySQL
AI algorithms rewrite and re-index slow PostgreSQL and MySQL queries, then explain precisely which changes were made and how they improve performance.
A non-intrusive sensor continuously monitors your database and generates easy-to-read optimization insights you can act on immediately.
Detects redundant or missing indexes and suggests schema optimizations that lower CPU, memory, and storage usage.
Highlights recommendations that cut monthly database spend by removing waste and tightening schema design.

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.
