On the same Wi-Fi
Your devices talk straight to each other across your own network. Nothing in between.
Works — directly

सन्धि san·dhi
The cross-device AI agent
Prompt any device, from any device, anywhere.
No account · No telemetry · Your model, your keys
Brought to you by Aitele Research
Sandhi joins every device you own into one private network with an AI inside it — ask on any of them, and it acts on whichever one the task belongs to. The thinking stays on your desktop, and the link your devices speak over is one only they can read.
Anywhere
Same Wi-Fi? Not required.
Your devices never have to share a network. On the same Wi-Fi they talk directly. On different networks — mobile data, office Wi-Fi, another country — they meet through your own private relay, which carries the traffic without ever being able to read it.
On different networks
Mobile data, office Wi-Fi, another country — they meet through a relay you control, which carries the message without being able to open it.
Works — via your relay
Security
Locked to your devices only.
Set up once, safely
Scan the code on your desktop and type your password. Only devices you approve this way can ever join.
Nobody in between can read it
Everything is scrambled on the device it leaves and can only be unscrambled by the device you sent it to.
Private away from home too
Off your Wi-Fi, your devices talk through a relay you control. It passes the message along without being able to open it.
You only need the password when adding a device — after that they reconnect on their own. Change it whenever you like, and every device has to be approved again. Under the hood: end-to-end encryption, with the keys held only on your own devices.
The brain
Choose where the thinking happens.
Fully local
Run a local model with Ollama. Screens, plans, results — the loop spins inside your house and nothing leaves it.
Your API key
Point it at any OpenAI-compatible endpoint, called directly with your key — no server of ours in the path. That provider sees each step's screenshot; you chose it, you can leave it.
Sandhi Cloud soon
A hosted option for zero-setup days. Opt-in only, stateless by design — and never required.
Multi-device
Two devices free.
A fleet when you need one.
Pair two mobile devices — phones, tablets, or one of each — at no cost, on top of the desktop or laptop running the brain. That is enough to actually use Sandhi, not a teaser. Switch on Pro mode to pair up to ten, name them, type them, and target any from any.
mobile devices on Pro, plus your desktop/laptop ·
unlimited on Enterprise
For teams & enterprises
Built for buildings full of devices.
One desktop can hold a whole floor of phones and tablets — named, typed and driven from wherever you are, over infrastructure you own end to end.
A QA bench of real handsets
Drive real devices through real flows — no emulator farm. Pair the lab once, pick a handset, run the case.
Kiosks that reset themselves
Every lobby tablet back to its morning state — scheduled per device, on time, unattended.
IT reach, no vendor cloud
Fix a device across the country through your own relay — encrypted end to end the whole way, with nothing in the middle that can read it.
Self-hosted relay
On-prem models via Ollama
No third-party cloud in the path
