✨ Create your companion
A guided setup with cards, about 5 minutes. Every step can be skipped.
Start from a character ?
Her picture stays when you choose a character. Make a new look
Import a character… ?
Or drop a file here. A Sara character file keeps everything (look and voice too); a card is the format other apps read.

You can have more than one companion on this server. Each has her own name, character, look, voice, conversations and memories. They share your sign-in, devices, keys, models, tools and backups. Switch between them with ⇄ at the top of the sidebar.

Bring your chats from Character.AI, SillyTavern, Replika, Nomi, Kindroid, ChatGPT, Claude or a saved transcript. She reads them and suggests what she learned about you, your history together and her character. Nothing is saved until you check it and press Save. How to export from each app
Choose the file
A .zip export (up to 200 MB) or one chat file: .json, .jsonl, .csv, .txt or .md (up to 50 MB). Character cards are imported in Name and personality instead.

Let her read them Read without a model Never mind
She can ring you, like a phone call, in the Sara app on your phone or in this browser. Answer and she tells you why she called. Miss it and she sends it as a message instead.
Call me now
To ring on a locked phone, Android needs your OK. Allow full-screen calls
Android: switch on Instant notifications (Connections → Phone and notifications) so the phone can ring. iPhone: rings while the app is open; otherwise a “Sara is calling” notification (needs your Apple push key, Settings → Phone and notifications).
Sara can send you photos of herself. Her own portraits cost nothing. New pictures are made with xAI Grok Imagine from her look, using your Grok subscription (or an xAI API key); she asks first unless you change take_photo above.

Only her own portraits

Run her model on this computer, and if you like, keep everything here: nothing goes to the internet.
Nothing leaves this computer ?
First get a model on this computer (below). Then turn this on.
What would leave this computer (paused while it's on)
Phones and computers on your home network or Tailscale can still open Sara here, if you set it up that way: they connect in, Sara doesn't reach out. On Windows her commands can't be fully cut off from the internet; see the guide.

Model to download ?

Every job uses your default model unless you pick one here. A conversation's own model choice still wins. ✨ Use recommended fills in picks from what's connected; changes save by themselves.

Once a day at the time you pick, Sara sends a short message with the weather and what's on your list (due to-dos and reminders). It arrives like her other messages: in chat, as a notification and on Telegram/Discord if linked. Weather comes from Open-Meteo (free, no account).

Weekly review
Once a week she looks back with you: what got done, what's overdue or stalled, and a short plan for next week from your to-dos, reminders and calendar. You can also ask for one any time (Planner → Review my week).
Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday
Time
Yearly look back
On the anniversary of your first message, she writes a look back at your year together from Your story (milestones, promises, projects, moments) and sends it like her other messages, outside quiet hours. You can also ask for one any time on the Your story page.
Adult mode can only be turned on in a web browser, not in the phone apps.
Browser for testing ?
Look again
Sign out of Google
Set it up (about 10 minutes, once)
She reads your email and calendar through Google's own APIs, using a small Google app that you own, so nothing goes through anyone else. Reading is automatic; drafting, sending and adding events always ask you first.
Open Google Cloud Console and make a project (any name, e.g. "Sara").
Turn on the Gmail API and the Google Calendar API (press Enable on each).
Open Google Auth Platform → Get started: app name "Sara", your email, Audience External .
Under Audience , press Publish app (otherwise Google signs her out every 7 days). Google will call it unverified; that's expected for your own app.
Under Clients → Create client → Web application . Under Authorized redirect URIs add exactly:Copy
Copy the Client ID and Client secret it shows into the boxes below and press Save.
Press Sign in with Google . On the "Google hasn't verified this app" page choose Advanced → Go to Sara , and leave all the boxes ticked.
Client ID Client secret Save
Sign in with Google Remove the Google app
Using another email provider? Email and calendar with an app password are under "Tools from other programs" below (Fastmail, iCloud, Outlook and more).
What she knows about the code in each workspace: how to build and test it, its layout and rules, and the notes she keeps (decisions, conventions, commands). She looks again by herself every hour; coding conversations and her team use it.
Workspace Look again
After a tricky job goes well she can write down how she did it (a recipe : when to use it and the steps that worked). In coding conversations she sees the recipes that fit what you ask and follows them. Saving one asks you first; you can change that for recipe_save in Tools and approvals.
Let her see and control your home through Home Assistant : lights, switches, thermostats, locks, blinds, scenes. She can look on her own; every change asks you first. Your Home Assistant must be reachable from this server (for example your Nabu Casa address, or over Tailscale).
Home Assistant address
Long-lived access token
Make one in Home Assistant: click your name (bottom left) → Security → Long-lived access tokens → Create token.
Save and test Disconnect
Presence
She can notice when you get home, leave, go to bed or switch the lights on in the morning, and say a short word: a message on your devices, an announcement on a speaker, or both. Off until you switch it on, for this companion. Each kind at most once every few hours, never in the quiet hours of Calls from her.
Connect Home Assistant above first.
Let her work on your other servers over SSH, with a password or a key. Every command she runs there asks you first (you can change that in Tools and approvals), and risky ones always ask. After you sign in once with a password she makes her own key for that server and stops using the password.

Files over 100 MB need to be PDFs. Behind a reverse proxy, big files are sent in 8 MB pieces, so a proxy limit of 10 MB or more is enough.
Talk to her from other apps, with her own memory and personality: chat apps like SillyTavern and Open WebUI (they speak the OpenAI way), and MCP apps like Claude Code, Cursor and Claude Desktop (they can use her memory, planner, library and notes). Give each app its own API key. Her safety rules and the AI notice always apply.

SillyTavern
Open API Connections (the plug icon) and choose Chat Completion.
As the source choose Custom (OpenAI-compatible).
Paste her chat address as the Custom Endpoint and your API key as the key, then press Connect and pick the model sara.
She keeps her own memory and only reads your newest message. To let SillyTavern send its whole chat and character prompt instead, add the header X-Sara-History: client (Additional Parameters → Include Headers).
Open WebUI
Open Admin Panel → Settings → Connections.
Under OpenAI API press +, paste her chat address as the URL and your API key as the key, and save.
Pick sara as the model in a new chat.
Claude Code
First put your API key in SARA_API_KEY: run the line for your computer in a terminal, paste the key and press Enter. This way the key never lands in your shell history.

Export and import
Download everything (chats, memories, to-dos, reminders, notes) as one file, or bring in a file from another Sara. Keys and passwords are blanked out in the export; add your provider keys again after moving.
New versions bring fixes and new things to do. Updating makes a backup first, then installs and restarts Sara (about a minute; conversations in progress stop). If the new version doesn't start properly, Sara goes back to the version she had by herself.
Check for updates Update now
Download the new version
To update her: sudo sara update. This server updates from the command line. On the server run sudo sara update (Docker: docker compose pull && docker compose up -d).
Invite other adults to use this server with their own companions and a private space of their own. You choose which models they may use and how much a day. You can't read their conversations, memories, companions or moments: you only see how much they use, to manage the bill.

People
Nobody else uses this server yet.
Whoever runs a server can technically read its disk, and your server backups contain every space (encrypted when they leave the server). The app itself never shows you their data.
You use this server as a member of the owner's household. Your companions, conversations, memories, planner, library and moments are yours: the owner can't read them, and sees only how many messages you send and roughly what they cost.
