We're excited to join forces with @SpaceX to advance the frontier of useful AI. Expect significant improvements to Cursor soon.
SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models.
For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.
We look forward to working closely with the Cursor team to advance our frontier AI capabilities

Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI.
SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI.
The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.
Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

The loudest story about AI is a lonely one. One person with an army of chatbots. Other humans are friction.
That gets the future wrong. The best things aren’t built alone.
In a moment of change, we want to remind the world (and ourselves) what Notion stands for:
— Think Together

hello hi, I am once again telling you THIS WORKS!! I sent @benln a cold email a month ago w/ a notion doc included on how I'd help scale @cursor_ai community AND NOW I WORK HERE! send the email.

You can now easily give Cursor access to your knowledge bases, deployment environments, observability suite, internal tools, and design files.
Ask it to figure out an error by scanning through Datadog, hunt down runbooks in Notion, deploy to AWS, or replicate a mock from Figma.
Much of this was possible before, but it was too hard. Now it feels like installing an app! You can configure plugins for your whole team too.

This work by @cursor_ai is, I think, the coolest AI breakthrough since GPT-4. (And there are plenty of candidates!)

We built a browser with GPT-5.2 in Cursor. It ran uninterrupted for one week.
It's 3M+ lines of code across thousands of files. The rendering engine is from-scratch in Rust with HTML parsing, CSS cascade, layout, text shaping, paint, and a custom JS VM.
It *kind of* works! It still has issues and is of course very far from Webkit/Chromium parity, but we were astonished that simple websites render quickly and largely correctly.

Cursor seeks to be the best and most powerful way to code with AI.
What are the ways in which we could be better?

Graphite is joining Cursor.

We raised $11M from Keith Rabois at Khosla and Felicis to make MCP work at scale.
MCP is everywhere, but it's MESSY.
No security. No auth layer. No visibility. No control.
We built Runlayer to enable AI.

Our CTO, Ben, has tabbed on @cursor_ai 168,176 times this year.
We know this because Cursor sent him an email (with a gift) saying he was one of their power users. If you're doing the math, that's 575 tabs per day!
Ben's a pragmatist, so he doesn't like AI generating entire features for him. He thinks the code it generates can be poor and insecure. But he does believe that tabbing to autocomplete saves him SO MUCH time.
He uses Tab so much that his pinky hurts, and he often switches to tabbing with his ring finger when he codes at night 😅
At Miru, we use AI to go fast, but never at the expense of writing good, reliable code. That's why we're top of the charts for Cursor Tab, but not full-stack codegen apps like Lovable ;)
And check out a physical Cursor Tab they sent to the office!

So for 5 years, “offline” has been the #1 request.
Today, thanks to the perseverance of our engineering team, @NotionHQ finally works offline. Your ideas don’t need Wi‑Fi to exist!
For Notion community: thank you for your patience while we built this right.
This is a journey, I want to share what we had to invent to make this real... 1/n
