[Littlebird @LittlebirdAI]

The most human thing about us is that we forget. What if Littlebird could help fill in the gaps and help you remember?

[Littlebird @LittlebirdAI]

Ask for yesterday's meeting notes, get them.
Ask if 4pm is open, it's booked.
Ask where the latest script is, there it is.

Everything you need, minus the searching.

KIMI FOUNDER JUST DROPPED A 40-MINUTE MASTERCLASS.

The exact architecture behind a $20B valuation — there's no faster way to learn how to build AI agents right now.

Bookmark this for the weekend.

40 minutes. zero fluff. from the person who built it.

Optimization → Linear Attention → Sub-Agents → Open Systems → Cash

How do you qualify for the Boston Marathon?

@maddielamere just did. We made a 1-minute documentary about it.

Behind every iPhone. His compiler.
Behind every Android. His compiler.
Behind every NVIDIA GPU. His compiler.

One American. Billions of devices. 🤯

Meet Chris Lattner 🇺🇸

> Started LLVM in late 2000 at UIUC as part of his graduate research.
> LLVM is a compiler infrastructure ~ the software that turns code into machine instructions.
> Apple hired him in 2005. He stayed 12 years.
> His toolchain now powers iPhone, iPad, Mac, PlayStation, Android NDK, and NVIDIA's CUDA.
> Also built Clang ~ the C/C++ compiler used by Google, Microsoft, and Sony.
> Built Swift in secret. Nights and weekends. While leading a 40+ person Apple team by day.
> Apple leadership was skeptical. He shipped it anyway. 🚀
> Swift now powers the vast majority of iOS apps on earth.
> Won the ACM Software System Award ~ same as Unix, Java, and TCP/IP.
> 2017 ~ Tesla VP of Autopilot. Worked in Elon's orbit. Left in 5 months.
> Joined Google Brain. Built MLIR ~ the compiler infrastructure behind TensorFlow.
> 2020 ~ joined SiFive to build open-source chips competing with Intel and ARM.
> 2022 ~ left Big Tech entirely. Founded Modular AI.
> Built Mojo ~ a new AI language that runs Python up to 35,000x faster.
> LLVM, Clang, Swift — all open-source. Mojo follows in 2026.
> Targeting NVIDIA's $4.8 trillion CUDA dominance. Raised $380M. Valued at $1.6B.
> Still writes code. Still answers GitHub issues himself.

He spent over 25 years building the compilers Big Tech is built on.
Now he's openly building the one that could break NVIDIA.

What a mind. Compiler GOAT. 🧠🐐

@Dhavalsingh7 @cursor_ai Hi 👋

[Dmitriy Vasilyuk @ReasonMeThis]

Had an interview with a candidate coming up but couldn't tell who it was from their email in Google Meet. I ask @LittlebirdAI ofc, it goes full detective mode, digs up the exact right resume: first 2 letters of last name + first 3 of first name = email.

Littlebird for Windows is in public beta 🙌

We've heard from so many of you who wanted to use Littlebird but don't use a Mac. This release brings the Littlebird experience to Windows, so you can have an AI assistant that already knows what you're working on.

@birch_js this is heavily vibe coded and untested, with RN skia. I think pretext port can be created on top of RN skia as it has the measure text/font APIs (haven't checked all the capabilities though 😅).
Also native measure text API + absolute RN Texts might just work in theory.

[Cheng Lou @_chenglou]

Project’s at https://t.co/meTmVhJXlk
`npm`/`bun install @chenglou/pretext` and throw your AI into making cool demos for it!

[Addy Osmani @addyosmani]

Build the thing that feels too ambitious.

If you're using agents to do exactly what you were doing before - just faster - you may be thinking too small.

Ambitious is the right size side-project.

[sunil pai @threepointone]

canon event, mark the day.

[Yash @knoxyash]

We hit #1 on launch day - now we're going for weekly #1. If you believe in what we're building, an upvote means the world.

[Littlebird @LittlebirdAI]

We were #1 Product of the Day on @ProductHunt yesterday! 🐦‍⬛

Thank you to everyone who supported us. The response was unreal!

And we're just getting started...

[Yash @knoxyash]

Someone just said this about Littlebird:

"It doesn't force me to think like a machine. It thinks alongside me. Please keep building for messy, complicated, non-linear humans."

We intend to. Support us on Product Hunt : https://t.co/jXIHBpHQeS

[Littlebird @LittlebirdAI]

Earlier this week we announced our $11M raise and today we're live on @ProductHunt!

Littlebird is the only full-context AI. It learns from your screen and meetings so it already knows what you're working on when you need help. 84% of users say it saves them half a day every week.

If you haven't tried Littlebird yet, today's a great time.

[Tushar @tushartrip]

we finished on top 🚀🚀

do checkout the Producthunt comments from our users. if you've not tried us out, you're really missing out.

[Tushar @tushartrip]

playing with proactivity ideas, wdyt?

[Deepankar @DeepankarBhade]

A truly context-aware AI knows when it's being launched on Product Hunt.

Show some love ;) 🚀
