Across a large panel of real browsing sessions, we studied how work moves from page by page to see where people go next. Every jump tells a story about how work really gets done.

Here’s what 700 of the most-used sites told us 🧵 (1/5)

Today we're releasing Composite-Bench: a long-horizon computer-use benchmark with certified-optimal answers and verified compute.

The strongest open-weights model isn't Kimi K3. GLM-5.2 beats it by 32 points and clears every closed model we tested except Claude.

So excited to be announcing our $5.6M seed round and launching major new features with @KicksCharlie and the @CompositeAI team!

We launched @CompositeAI eight weeks ago as the first autopilot for your browser.

Since July, thousands of professionals across hundreds of companies including Tesla, Salesforce, Google, Uber, and DoorDash have trusted Composite to eliminate digital browser tasks.

So they can focus on high-leverage work.

From moving tickets, to researching across internal sites, to pulling data or dashboards, Composite is the single best way to get work done in your browser.

Today, we're thrilled to announce our $5.6M seed round from NFDG, Anthology Fund (@MenloVentures + @AnthropicAI ) and dozens of incredible investors and angels.

We’re also keen to share three massive updates to Composite that transform how you work:

1/ 🔎 Spotlight View
2/ 🧠 Personalized Suggestions
3/ 💻 Available for Mac AND Windows

Other AI browsers force you to abandon your existing setup.

Composite works in the browser you already use to immediately take tasks off your plate.

Cmd + Shift + Space on any website. Instantly.

I used to spend hours hunting through dashboards and docs instead of doing talking to users and crafting products.

We're all digital factory workers stuck in Chrome tabs.

Excited to announce @CompositeAI so you can finalizing focus on your high-leverage work

The way agents use the internet is broken.

They don't have access to your accounts, they're blocked on half of all websites, & they take hours to set up.

Today, we're introducing @CompositeAI - the agent that connects to your browser to automate your mundane tasks.
