We worked intensely on Claude Docs for the last few months - so excited to finally have our work out there
Vivek Nair retweeted
Claude now works inside Google Docs, Sheets, and Slides, and those files also open inside Claude.
In Google Workspace, Claude sits in a sidebar next to your file, reads what you have open, and edits it in place. You can approve each edit before it lands.

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.
Available today at the same price.

Introducing Claude Opus 4.7, our most capable Opus model yet.
It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.
You can hand off your hardest work with less supervision.

We're bringing the Claude in Office ecosystem closer together. Would love to know what you think. I poured my soul into this one and want it to feel great!
I’m so grateful to work here. Very proud of the tough, principled decisions we’re making here.

Simile is out of stealth!
At Simile, we have built the first AI simulation of society, populated by agents based on real humans.
We are building a foundation model that predicts human behavior in any situation, and a product that deploys it at scale.
Thrilled to be on this mission.
Truly privileged to have worked on this!
We're bringing Claude to millions of knowledge workers - beyond just coding.
If you're heavy in finance (or just an Excel nerd), let us know what you think.
Claude in Excel is now available on Pro plans.
Claude now accepts multiple files via drag and drop, avoids overwriting your existing cells, and handles longer sessions with auto compaction.

Finally, AI designs you can edit.
Moda - create brand assets on a fully editable canvas.
This is not another ChatGPT or nano banana wrapper.
We actually taught an agent layout, typography, and color. We gave it taste.
Use it for slides, social, infographics, e-books …
We spent the first year at @GentraceAI helping customers run traditional LLM evaluations. But we realized late last year that agents changed everything.
Agents don't just generate text - they take actions, make decisions, and interact across multiple steps.
Traditional "hallucination" checks can't evaluate whether your agent booked the right flight or resolved the customer’s support ticket correctly.
Old LLM observability tools were built for simple input/output prompts. They break in an agentic world.
For the last 9 months, we rebuilt Gentrace from first principles 🔥 Here's our new approach:
- Chat with your AI trace data using our agent to discover what's actually breaking
- Describe problems in plain English
- Our agent creates custom AI-powered monitoring columns that catch these failures across all future traces
Example: Instead of checking "factual accuracy," you can now evaluate complex behaviors:
- "Figure out if a user is frustrated with my AI agent in the customer support chat"
- "Detect when my agent takes more than 5 steps to answer simple queries."
We stopped measuring outputs and started measuring outcomes. Watch @dougsafreno break down how to solve agent observability with Gentrace. 👇
Agents are significantly more powerful than standalone LLM calls. But, debugging them is a nightmare.
You can trace their reasoning and tool use, but traces get huge and are impossible to parse.
To solve this, we spent the lasts several months building Gentrace for Agents, which puts our own agents to work on yours.
In Gentrace for Agents, you can:
• Chat with AI to debug agent traces
• Create smart monitoring columns
• Build out tailored evaluations
It’s like a giant AI powered spreadsheet over your trace data, with a Cursor-style chat sidecar. If it sounds a little meta, it is, but it is very powerful in practice.
We recorded this video to show you how it works. Take a look, and let me know what you think:

I made a simple Chrome Extension to copy a Github PR diff into your clipboard.
This makes it dead simple to understand what's changed.
Press ⌘ + C twice to copy to clipboard. This mimics Superhuman's behavior with copying an email thread.
If you're selecting text elsewhere on the page, the extension does not activate.
