Instant Postgres branches so coding agents can test safely
Create a 1:1 copy of any Postgres database in under six seconds and keep that speed even at terabyte scale, so agents never wait on test environments.
Every branch is isolated at the compute and storage level, meaning experiments, migrations, and data cleaning can never reach or damage production.
Clones only consume storage for the changes actually made, instead of duplicating the full dataset for every branch.
Branch compute scales with agent workloads and drops to zero when idle, so you never pay to keep idle test databases running.

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.
