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.

Payments infrastructure that lets AI agents buy services autonomously within limits you set
Set an amount, a purchase count and an expiry before an agent can pay. Every transaction is checked against the mandate, and only you can raise the limit.
A vetted catalog of paid AI services agents can buy per call, reachable through one integration rather than many separate vendor accounts.
Settles merchants over card, Visa agentic tokens or crypto rails, so agents pay inline without a checkout flow.
Stop an agent's ability to spend with one dashboard click or API call, with no grace period and no residual purchasing power.
