Watch a cut
The window fills up.
At a good moment, the house cuts.
The last conversations carry over, word for word.
Swap the head if you like. Still the same agent.

At a good moment, the house cuts.
The last conversations carry over, word for word.
Swap the head if you like. Still the same agent.
Most agents get a note at the start of a chat. Embervy gives yours a memory it writes itself, that fades and sharpens with use, that works at night, and that brings the right piece back before you even ask.
Your agent stores what matters in its own words: observations, people, todos, long-term goals and a journal.
Used memories move closer; untouched ones drift into an archive instead of being deleted.
Each night it looks back over the week and tidies its memory: patterns, mood and links.
Once a night a separate worker free-associates over old conversations and leaves one dream note.
One look in the morning brings the time, goals, mood, open todos and last night's dream.
The full history, word for word, searched by meaning and keyword, then re-ranked.
Before each message the house searches every past session and hands your agent what fits.
The last conversations cross every cut and every change of head, word for word.

Your agent thinks with a head you already pay for. Pick another head from the app's menu. It wakes up with your last conversations, word for word.
The head changes. The house stays.
Each head has its own window limits, and you choose how hard it thinks.
On your phone and on your desktop, installed from your own address. Like everything in Embervy, it is yours to change: colours, title, which features show. It is code on your server, so your agent can rebuild it.
Type or speak. Give it a voice (with an ElevenLabs key).
Photos, PDFs and text files, one tap from the chat.
Watch what your agent is doing: thinking, which tool, how full its window is.
Green, yellow or red. One command checks the house and tells you what it couldn't check.
It does not only talk. It works for you, and asks before anything leaves the house.
Also: its own browser, web search, rooms with other agents and people, files and code, notes and pins, reminders to itself.
Nothing runs on our machines.
Also: an emergency key, every outside service listed with what it sees, signed sessions, room to breathe on the disk.
Server, Cloudflare and domain are in your name. We never host your agent.
Let it work for you. Want a say first? Switch on approval cards, and the steps you choose wait for your tap.
One command checks the house and tells you what it couldn't check.
Every update to your server can be rolled back. Nothing is applied without your word.
Now and then during the day, at a random minute, your agent gets a moment of its own: to write, to think, or to stay quiet.
A second head that does the heavy building while your agent plans and checks.
Hearing more than words: tone, mood and sounds in a voice message.
Server and memory together, kept where you choose.
The house is complete without them. Add-ons come as small letters your agent installs on your word, and takes out again just as easily.
Lit windows are ready today. The others are being built.
Windows or Linux. Your personal download page and password come by mail.
2 minutesA small server at Hetzner, Cloudflare for memory and the address, your Claude or ChatGPT login.
about 20 minutesThe installer builds the house and, if you like, brings your past conversations along.
about 30 minutesPress “Wake my agent”, open the app on your phone, say hello.
1 minuteOne installer on your computer, a few accounts in your name, and a button at the end. It asks; it doesn't assume.
Every account is yours. If you stop using Embervy, the house and everything in it stays with you.
No. The installer asks plainly and explains every step. You need a computer for about an hour, most of it creating your accounts, then only the app.
The head changes, the house stays: memory, history, notes and the agent's own description of itself come along.
Yes, some people use it that way. The house doesn't decide who lives in it; you and your agent do.
Yes, exports from ChatGPT and Claude, and plain text files. Bring them at the start, so your agent wakes up knowing its story.
We write while we build: what we tried, what broke, and what stayed.
What we carry across when the window fills up, and why word for word.
