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.

A shared AI workspace where agents research, create, and publish on schedule
Describe a recurring task in plain language and Kollab plans the steps, picks models and apps, then runs it on a schedule without a visual workflow builder or code.
Access chat, image, video, and voice models from multiple providers inside a single account, using one shared credit balance.
Authorize tools like Gmail, Notion, Slack, Instagram, Search Console, Google Ads, Shopify, and HubSpot so agents can read and write inside them.
Projects, finished outputs, and credits live together, and unlimited team seats are included on every plan.
