Agent-native notebook for cloud data science and ML workflows
An autonomous AI agent works inside your notebook, sourcing datasets, preprocessing data, engineering features and running experiments alongside you.
Launch parallel experiments, replicate kernels and compare model architectures simultaneously instead of queuing work serially.
Start on a CPU sandbox and scale up to T4, L4, A10, A100 or H200 GPUs with configurable RAM as your workloads grow.
Durable execution keeps long-running jobs alive across spot interruptions, with checkpoint storage from 5 GB on Free up to 2 TB on Max.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
