Still developing MindClip based on user feedback.

Got the following from a user:

The problem: "When you copy a lot of values like keys, numbers and so on, it easily gets messy and it's hard to identify what's what."

The solution: When you copy something, it now also captures the context around what you're copying and uses ___ to show which value it refers to.

Also added the option to put a custom tag on any item.

We’ve shipped a security-guidance plugin for Claude Code that helps identify and fix vulnerabilities as you’re writing code.

Available for all Claude Code users. Install from the plugin marketplace (/plugins).

[Mathias Karlsson @mathiaskarlsson]

Just shipped MindClip 3.0!

Introducing Boards!

Running a demo or presentation? Keep a Board on a second screen — pre-populated with text, images, files, whatever you need. It stays open the whole time, ready to paste with a click or a keystroke.

Export your Board as a .mcboard file and send it to a friend. They double-click it — done. They've got the exact same set, assets and all.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

You've been asking for this one...

Now in preview: Codex in the ChatGPT mobile app.

Start new work, review outputs, steer execution, and approve next steps, all from the ChatGPT mobile app. Codex will keep running on your laptop, Mac mini, or devbox.

Holy shit... someone made it work that I can integrate a social media manager inside Claude

It's called OmniSocials and it lets Claude draft, schedule, and publish to 10 platforms from a single command.

No Hootsuite. No Buffer. No $200/seat pricing.

Here's everything you need to know: 👇

People talk, listen, watch, think, and collaborate at the same time, in real time. We've designed an AI that works with people the same way.

We share our approach, early results, and a quick look at our model in action.

Introducing the Lovable aesthetics update, a new level of design in vibe coding.

Ask for typography, layout, and color preferences. Preview design concepts before building, and create bolder landing pages, apps, and blogs.

Managing API keys is one of the top security concerns we hear from customers.

Today we’re introducing keyless auth for Claude Platform: authenticate via browser with the CLI, or let workloads use their existing cloud identity (AWS, GCP, Azure, or any OIDC token provider).

Announcing Cofounder 2: Run an entire company with agents.

It's the infrastructure for the one person billion dollar company - orchestrating agents across engineering, sales, marketing, ops, and design.

(and yes that's my real grandma in the video)

[Mike Bespalov @bbssppllvv]

Agents make ugly UIs because they've never seen good design.

We've been fixing that, 2,000 DESIGN.md files from the world's best products, structured for a model to read and learn. Colors, type, spacing, layouts and more.

Claude Security is now in public beta for Claude Enterprise customers.

Claude scans your codebase for vulnerabilities, validates each finding to cut false positives, and suggests patches you can review and approve.

@leejihoondd Thank you:)

Just… hold… V.

A few weeks ago I posted about MindClip, a clipboard manager for macOS I built as a side project.

The response? Way better than expected.

"So simple, so useful." "Everyday use." "Why doesn't macOS just do this?"

Of course, some people pointed out: "There are already apps that do this, with thousands of features and AI that solves everything just by looking at it..."

Yeah. There are.

My take is simple. I built something I use every single day. An app that solves a daily need, just works, and lives in the keys you already use.

Sometimes that's enough.

What it does:
→ Hold Cmd+V to pick from your clipboard history
→ Select multiple items and paste them all at once
→ Mixed content works — files, images, and text together
→ Screenshots automatically land in your history → History survives restarts

Since the first post, MindClip went from free side project to launched product.
72-hour trial, then a one-time payment of ~$7.
Lifetime updates.
Support if something breaks. Done.

The site is up. The app is out. And the first payment came in. 👌🏻

These aren't life-changing numbers, but every dollar goes back into development and hopefully into project number two, which is already in the works and will help patients in healthcare. More on that later.

And one more thing, to everyone who downloaded early, tested, and gave feedback before there was even a finished product: thank you. Reach out and I'll get you a license key. Obviously.

So if you're on a Mac and you use Cmd+C and Cmd+V every day, this one's for you.

The clipboard macOS should have built...

Just… hold… V.

OpenClaw released v2026.4.26, and it just killed every AI voice tool.

It can now answer your phone, make call and talk back in real time.
AND import your entire Claude Code setup in one command.

Which outreach campaign to business should I try?
The AI agent era is crazy and beautiful.

[OpenAI Developers @OpenAIDevs]

You can build interactive applications with gpt-realtime-1.5, so users can control app state more naturally with voice.
