A few things to know.

What is an AI workspace?

It’s a place where you and AI work on the same things, together. River comes with apps for documents, spreadsheets, presentations, and more, so it works right in your files, alongside you. Download it for Mac, Windows, or Linux, or use it on the web.

How is River different from an AI chat?

Chat is great for quick questions. In River, your work lives in real documents, sheets, and decks that you and River edit together, so every round builds on the last. River’s edits arrive as suggestions, and it remembers what you tell it about your work.

Can I use my existing files and tools?

Yes. Upload your files and connect apps like Gmail, Slack, and Notion. The desktop app also works with the files on your Mac or PC, and with your own signed-in browser.

Am I in control?

Always. Edit anything yourself, and keep or reject every change River suggests. River asks before it sends, publishes, or buys anything, unless you’ve already asked it to.

Is my work private?

Yes. Your work is encrypted in transit and at rest, and River never uses it to train AI.

What does River cost?

River is free to start. Paid plans add more AI use and the most advanced models.
