What Compose.ai does

Compose AI is a free Chrome extension that helps automate your writing using AI. You know how Gmail autocompletes your emails? Compose.ai is like that but everywhere, like how Grammarly works.

Describe what your company does in 50 characters or less.

Cut your writing time by 40% with AI autocomplete

What is your company going to make? Please describe your product and what it does or will do.

We built Compose AI, a Chrome extension that uses AI to autocomplete your writing everywhere online. It expands beyond Gmail's basic autocomplete to help users write faster in emails, documents, and anywhere they type. It's like Grammarly's integration model but focused on generating text suggestions that speed up writing, not just correcting grammar.

Where do you live now, and where would the company be based after YC?

We live and work in San Francisco, CA, with part of our team remote. After YC, the company will remain based in San Francisco.

Explain your decision regarding location.

San Francisco has the talent and investor access critical to building a technically sophisticated AI product like Compose AI. It also helps us stay connected to the startup community and users developing new writing workflows.
