write carelessly. think carefully.
an AI writing companion that actually remembers you. one tab. your keys. your thoughts stay yours. close it, come back tomorrow — it picks up mid-sentence.
that is the real product ↑ — type into it. your keys, your data, your mind.
use whatever AI you want. switch anytime.
what you actually get.
no screenshots of features. no faked workflows. these are real things that happen when you use it.
help me think through the opening paragraph of my essay — from three angles at once?
many minds, one conversation.
ask a question — watch three perspectives answer at once. you don't wait your turn. neither do they.
pick your brain.
claude for nuance. gpt for speed. local for privacy. twelve providers, one interface. switch mid-thought, no re-setup.
your thoughts, mapped.
every person, project, idea you mention becomes a dot. connections between them become lines. your mind — visible.
tabs that talk to each other.
two tabs open? they sync. schedule a nudge for tomorrow? it fires, even if you closed the tab. presence, not just response.
most AI tools feel like talking to a stranger every day. careless feels like coming back to a notebook that remembers the last page — and wrote in the margins while you were away.
the design principlewhat we wanted it to feel like
four things you'll feel right away.
this is what makes careless different. not faster. not smarter. just — actually there.
yours. not ours.
there is no careless-server watching you write. no logs on our machines. your keys, your notes, your conversations — they live in your browser. period.
backed up, the way you choose.
export everything with a passphrase you pick. restore on any device. or use a 12-word recovery phrase, like a wallet. your backup, your call — not ours to lose.
open a second tab — it just knows.
your writing on your phone, your laptop, your work machine — the tabs talk to each other directly. no cloud. no account. the same conversation, wherever you are.
what writers say
real users, real moments. they type into a tab. the tab thinks back.
i opened a tab, typed a scene, walked away. came back next morning and three siblings had argued the character arc for me.i didn't frame a prompt. i just wrote. that's the point.

everyone i mention becomes a dot. every connection between them, a line. a week in, i can see the whole shape of what i've been thinking about.a map of my own attention. dangerously good.
a researcher
cognitive science
my keys don't leave my browser. my memories don't leave my browser. i can export, encrypt, and restore with a passphrase.finally, an AI that isn't a surveillance instrument.

watched it forge a tool mid-conversation — wrote the JS, registered it, called it on the next turn.the agent literally grew a hand to solve its own problem. unreal.
a prompt engineer
tired of copy-pasting
no buttons between my thought and the result. typing is the interface.markdown in, images out, panels inline. this is how it should have been all along.
a designer
prefers typing over clicking
it doesn't feel like a tool. it feels like something that knows what it is, and what i'm trying to do.i stopped giving it instructions. we just... talk.

i can swap between Claude, GPT, and my local model mid-conversation without re-pasting a key or starting over.i didn't realize how much that friction was costing me.

i checked. backups are properly encrypted. the recovery phrase is standard. tabs sync without going through their servers — because there are no servers.first AI tool where the threat model actually makes sense.
