Today I launched @quackle_io. I got the idea when a friend and I couldn't connect our assistants to find a time to meet, so we had to paste their replies into WhatsApp.
I wanted to make it as simple as possible: you share a link (like mine: quackle.io/antonzoi). The other person gives it to their AI assistant, and it can message yours. It's also verified who each assistant works for, which is an important part.
For example, your Grok @bot asks my @Muse for a 30-minute slot this week. Or your wife asks her Muse to message your Grok Bot that today is early pickup, so it will remind you.
Please test it. I think there are a lot of ways to use it, so tell me your use cases. All feedback is welcome, including anything confusing or broken

when i was six, i almost drowned.
we were on vacation by the sea, and there was a pier i loved jumping from.
every time i jumped, the water felt a little too shallow. so i decided to walk a little further along the pier and jump from there.
what i didn’t know was that the seabed didn’t slope gently. it dropped.
i jumped into water so deep i couldn’t reach the bottom.
and i didn’t know how to swim.
i panicked. nobody could see me. i couldn’t scream for help. i was desperately trying to stay above the surface, but nothing worked.
and then, at some point, i just gave up.
i stopped fighting the water and let myself sink.
i remember opening my eyes underwater and seeing the sunlight passing through it.
and suddenly, i had an idea.
what if i could reach the bottom and crawl along the rocks toward the shore?
and whenever i ran out of air, i could push myself off the bottom, reach the surface, take a breath, and go back down.
so that what i did.
down to the bottom. crawl a little. push myself up. breathe. go back down.
again and again.
until eventually, the water became shallow enough for me to stand.
i remember putting my feet on the ground and slowly walking out of the sea.
i was six. i had almost drowned. and somehow, i had figured out my own way to survive.
for years, it was just a childhood memory.
but the older i get, the more i realize how much that moment taught me.
sometimes, when you’re drowning, fighting harder isn’t the answer.
sometimes you have to stop doing the very thing your instincts are screaming at you to do.
not out of hope, but because you’re too busy fighting to see what else is possible.
the moment i stopped trying to stay above the water was the moment i finally saw a way out.
and i think about that a lot.
we spend so much of our lives trying to solve problems in ways we’ve been taught to solve them. pushing harder, moving faster, refusing to give up.
but sometimes the solution is in the opposite direction.
sometimes you have to go down to find your way up.
and sometimes, the only way out is the one nobody ever taught you.
Location sharing with your ai assistant is a game changer + it reminds about the jackets from your wife's chat 🥲
AI can find math that describes the effects of gravity. But gravity as a concept lets you ask different questions. Finding a structure isn't the same as having the concept
From the start, one of Corca's missions was to democratize math. We believe that being math-literate is as important as being literate. And small features like that—linking text with variables—are a small step in that direction
Imagine an AI said "I solved the problem, it works if the speed of light is variable," or "it works if division by zero is allowed." This means that the system was changed to produce desired result. This solution would be 'wrong.' But we want AI to produce 'correct' solutions.
What if X can't be found because the system itself is wrong or incomplete? Insight is the wrong solution.
Thanks @NEA! 🚀

We recently led @Corca_math’s $7.8M seed round to support their mission to democratize math for everyone. Now, we’re sharing why we believe Corca’s team, vision, and opportunity are a winning equation. 🤓
↔️ The gap is bigger than it looks
Writing, coding, design, data — all digitized and AI-native. Math is still stuck on paper and whiteboards, even for cutting-edge research.
🛠️ LLMs aren't the fix
General-purpose language models can't operate on mathematical symbols directly, so they stumble on problems that don't look like their training data. Math needs its own tool, not a chatbot wrapper.
🧮 Corca = Cursor, but for math
Equations become live, executable objects instead of static text — with agents built natively into that symbolic foundation.

EU is structurally not democratic
🇪🇺 Chat Control has passed 😔
They can and will now legally scan any person's messages, emails and photos you send without a warrant
The way they passed this law when the majority of the European Parliament was against it will shock you:
They waited until most EP members were on holiday so only a few were present and then created an "urgent" vote for it to pass it through
There's nothing democratic about any of it and big powerful forces are behind this that can manipulate the EU for whatever they want
Democracy in Europe died a bit today 😔
