ZZEND is a texting coach that works from your real conversation. Paste the chat and it reads the latest message against that person — how they usually text and what changed. It drafts a reply in 4 tones, lets you rehearse the conversation first, and tells you when waiting is the better move. Most...

As answered by people managing GitHub and ZZEND.
ZZEND's answer:
Because it remembers him, not your chats in general. Other tools start from zero every time you paste something. ZZEND builds a picture of that one person across every conversation you bring, and corrects it when you tell it it's wrong.
You can also rehearse before you send. Practice the conversation against a model of how he actually replies, then write the real one.
And the other person's messages are never stored. Only your own lines are kept, so the drafts sound like you.
ZZEND's answer:
People in the middle of a conversation that matters and they can't read it. After a fight, after three days of silence, after a breakup, or early on when you don't know them well enough yet to guess. Mostly US, mostly on a phone, usually at a moment when sending the wrong thing would cost something.
ZZEND's answer:
The problem isn't that you have nothing to say. It's that you have too much and nowhere to put it, so you run the conversation in your head over and over — with your own anxiety playing the other person. That simulation has no evidence in it.
ZZEND moves it outside your head and puts it on the record of how that person actually texts. Say the thing, see how it lands, then decide what to send.
ZZEND's answer:
Python (FastAPI) backend, SQLite, and a vanilla JavaScript PWA front end. Language work runs on Claude models.
ZZEND's answer:
Most texting tools read one screenshot and give you a clever line. ZZEND reads the new message against the person — how they usually text, what changed lately, what happened the last time they said something like this. So the answer comes with context: "he normally replies within the hour, and he hasn't for three days."
It also answers a question the others don't ask: should you send anything at all today? Sometimes the honest answer is no, and ZZEND will say so.

Am I the only one? Started a new work chat in ChatGPT to work on my public GitHub project, it reports:- Source: Hacker News / about 2 hours agofatal: unable to access 'https://github.com/':.
Then why hasn't there been a gTLD reserved for local use? The only ones that are reserved are .local and .home.arpa. .local is out, since it is entirely for use with mDNS / Bonjour. That leaves .home.arpa, which is very awkward.... - Source: Hacker News / about 21 hours ago
