[Willow @WillowVoiceAI]

Introducing the fastest way to vibe code.

Karpathy said English is the hottest new programming language. We took that seriously.

Today we're launching Willow for Developers — voice dictation built for vibe coding.

Your keyboard is the bottleneck. Kill it.

[Willow @WillowVoiceAI]

Your kids will ask why people used to type with their fingers. You won't have a good answer.

Introducing Willow Voice - the all new voice typing experience.

Fast. Personal. Inevitable. Now on Mac, Windows, and iOS.

[Allan Guo @_allanguo]

We raised $4.5m to build voice typing that actually works.

The founders of Reddit, Instacart, and Uber use it daily. 90% of users save over an hour a week.

What are you waiting for? Now on Mac, Windows, and iOS.

[Allan Guo @_allanguo]

The first Willow iOS user dictated a 47-paragraph breakup message in one take.

That’s how I knew we were onto something.

When voice actually works, people naturally choose it.

Curious? Try it yourself. Link below.

[Willow @WillowVoiceAI]

Introducing the next phase of Willow.

A world powered by voice.

@richysaltpacket @WillowVoiceAI 😁

[Claude @claudeai]

We’re expanding the research preview for Claude Code on the web.

Claude Code users on Team and Enterprise plans can now run coding tasks from their browser and the Claude iOS app.

Today we're introducing Limitless 2.0, the world's best personal assistant.
Here are 7 incredible things we just launched (and you won't want to miss the last one!)
1. Reminders: An automatic to-do list based on everything you verbally committed to throughout the day.
2. Limitless Live: You can now have a conversation with a personal assistant who knows you better than anyone on the planet, and you can ask it truly anything.
3. Daily Insights: This includes top highlights from the day decisions that were made, key things to follow up on, and opportunities to reflect and grow, as well as ideas that you might have had or everything you've committed to throughout the day.
4. Native Android app: It is live in the Google Play Store right now.
5. Recording using your phone's microphone: Now you don't need a Pendant to start to feel the magic of Limitless.
6. Full MCP support: Now you can seamlessly access your Limitless data from anywhere, including ChatGPT or Claude.
7. Best of all, for a limited time, we have cut the price of the Pendant and our bundle by a hundred dollars. That means the pendant is only $99. Download the iOS app or Android app for free or jump right in and buy the Pendant at limitless . ai for just $99.

Everyone deserves their own personal assistant and starting today, it is just $99 away.

today, we're launching Mosaic, the agentic video editor.

in a world tending towards AI slop, create something real.

no waitlist — public beta is now live at mosaic [dot] so.

[Eric Lay @itsericlay]

After 10 years of failed startups, I’ve finally found the next trillion dollar company.

Introducing @VirioAI — the AI marketer for enterprise.

As a teen I made content that did 1B+ views/month…
…and earned <$10K.

That’s when I learned:
Views ≠ Pipeline
Likes ≠ Revenue

The problem wasn’t creating attention. It was turning that attention into revenue.

Virio is built to solve exactly that:
1) Tracks your sales pipeline & marketing initiatives
2) Plans targeted content across your entire GTM team
3) Deploys messaging tailored to each decision maker

To celebrate our launch out of stealth, I'm giving away our 16,456-word playbook that's generated $50M+ in pipeline.

Repost & comment "Virio" and I’ll share it with you in a few minutes!

Yesterday, @WillowVoiceAI launched Personalization and sent every other dictation tool to a museum.

But here’s what surprises people the most... 🧵

[Willow @WillowVoiceAI]

Introducing Willow’s biggest update yet: Personalization.

It makes every other dictation tool feel like a stone tablet in the age of AI.

Here's why... 🧵

[Allan Guo @_allanguo]

This is the biggest unlock in async communication since Loom.

We just shipped Willow Personalization, our biggest update yet.

Willow now learns to match your exact tone and style across every app. Slack, email, and text 5x faster, while still sounding just like you.

[Allan Guo @_allanguo]

Announcing that @WillowVoiceAI has raised $4.2 million to build voice-first interfaces.

We started Willow after dropping out of Stanford freshman year to build a healthcare startup. It failed. We pivoted over 10 times, spent a year in the trenches, and learned how to build the hard way.

But we discovered something huge.

Voice scribes were giving doctors their lives back. They were able to focus on helping patients rather than wasting nights and weekends on paperwork.

That's when it hit us. If voice could transform healthcare, why not every knowledge worker? Why are a billion professionals still hammering away at keyboards to communicate with humans (email, Slack, writing) and AI (ChatGPT, Cursor)?

Today, thousands of professionals at companies like Canva, GitHub, and Webflow use Willow to work 5x faster.

We're building Willow to unlock voice as the universal interface where you can control any device, any app, any workflow simply by speaking.

Comment "Join Willow" to be fast-tracked.

The next decade will be defined by voice-first computing. The question isn't whether this transformation will happen. It's whether you'll be part of building it.

[Allan Guo @_allanguo]

99% of YC founders are too soft.

500k + a comfy place in Dogpatch.

My cofounders and I lived in the Tenderloin to stay on edge.

People got curb-stomped and fought every night.

YC says “don’t die.”

We had to learn that literally to build @WillowVoiceAI

[Y Combinator @ycombinator]

Human Behavior (@humanbehaviorai) is building an AI that watches actual customers using your product, through session replays, to help you understand why they stay, convert, or leave.

@_allanguo Congrats!

1. Speech is the last unfiltered signal.

Typing is filtered. Search is filtered. Even your mouse clicks are filtered.

But speech? Speech is the closest signal we can get to raw thought.

And Willow is building the infrastructure to ingest and personalize from it—at scale
