I always wanted a pen that tracked everything I ever wrote down So we built one

People are frying their brains with AI dependency while my 81 year old grandma manually writes down her Duolingo progress and marking her mistakes because she doesn't speak English but the Dutch course isn't available in Indonesian.

@TsT3v0 The Great Lock In^2

reviewing my github history for the last few years - april - november is my peak hacking season. starting to feel it coming on.

In 2026, I’m inviting 1,000 founders to San Francisco to start their companies. Are you in?

@jesselyu @rabbit_hmi @MKBHD @Youshaei Let’s goooo

i watched the latest @MKBHD interview with @Youshaei where rabbit r1 was briefly mentioned and i am glad that our team's hard word and resilience got recognized. "they've done a lot since launch and a lot of people telling me to re-review it cuz it's a totally different product now and i think it's fair." thanks, and it was hard to survive as a startup - heads down and keep building. clip credit to @Youshaei

@HamelHusain i am 37 seconds in and this is very confusing

They pulled off the impossible: made a real human video look 100% AI generated 🤣

For the past 12 months, I’ve been heads down building a robot. Introducing Emma – an autonomous robot that scans farms, detects diseases, and measures yield. Currently deployed in 14 vineyards and orchards in CA and NY.

@paulschneider_ @nuwapen @fortwearable I only trade pokemon 😔 But I did pre-order fort :)

@marctuinier @nuwapen Trade ya for a @fortwearable ;)

We built this because losing a good idea is genuinely painful.

@nachoagu7 @nuwapen It’s an ink pen that remembers what you write 😃

@marctuinier @nuwapen what is this lol

@ThroneScience Congrats Scott!

We have wearables to track our cardio and sleep. We have CGMs to track our metabolic health. But when it comes to our daily gut health, hydration, and urinary health, we've been completely in the dark. Today, that changes. Listen to your gut, with Throne.

@minafahmi Congrats Mina!

🚨: A bird flew 8,425 miles (13,560 km) from Alaska to Australia, without stopping even once — the longest non-stop flight ever recorded.

@_thinx sweet, gonna check this out

my ai practice is simple: ask your agents to build tools to level up themselves. it is worth it. my agents built this with autoresearch and my high level okrs, which cost me about 30 minutes in total :) they adopted it for the omi project so they can save 100x on testing the omi flutter app. github.com/beastoin/agent… -- sora: Omi E2E Tests — 4 Flows Side-by-Side: Screen + Live Test Log (25/25 PASS)
