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.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
