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

Questions
Asked, and answered.
What is Sandhi?
Sandhi is a cross-device AI agent. It joins your Windows PC and your Android phones and tablets into one private network with an AI inside it. Ask on any of them, and it does the task on whichever device it belongs to, reading the screen and clicking, tapping and typing the way you would.
Can I control my PC from my phone with AI?
Yes, and the other way round. Type or speak a request on your phone and Sandhi carries it out on your desktop; ask on the desktop and it acts on your phone. You describe the outcome, not the clicks.
How is Sandhi different from a chatbot or a remote-desktop app?
A chatbot answers in text, and a remote-desktop app hands you another screen to drive yourself. Sandhi takes the request and does the work itself, on the right device, over an end-to-end encrypted link between your own devices.
Which AI models does Sandhi work with?
Your choice. Run a local model with Ollama and nothing leaves your house, or point Sandhi at any OpenAI-compatible endpoint, such as Google AI Studio (Gemini) or OpenAI, with your own API key. It calls the provider directly, with no server of ours in the path. A free Google AI Studio key is enough to start.
Is Sandhi free?
Yes. The free plan is the full agent, with no account and no card, for your desktop or laptop plus two mobile devices. Pro raises that to ten mobile devices and adds Pro mode routing, and Enterprise has no limit. See pricing.
Does Sandhi need an account, or send my data anywhere?
No account and no telemetry: nothing about you or what you do is sent to us. The thinking runs on your own desktop, and messages between your devices are end-to-end encrypted with keys held only on those devices. If you choose a cloud model provider, the screenshots and text each step needs go to that provider.
Do my phone and PC need to be on the same Wi-Fi?
No. On the same Wi-Fi they talk directly. On different networks, such as mobile data, office Wi-Fi or another country, they meet through your own relay, which carries the traffic without being able to read it.
Which devices does Sandhi run on?
Windows 10 and 11 (x64) on the desktop or laptop that runs the brain, and Android 8.0 or later (arm64) on phones and tablets. macOS is coming shortly.
Can Sandhi use the apps I already have?
Yes. It works with what is on the screen, so it opens and uses the apps you already have, including Microsoft Store apps such as WhatsApp on Windows, without plugins or integrations.
Does Sandhi keep itself up to date?
Yes. While it can reach our server, it finds new versions, downloads them in the background, checks their signature and installs them while idle, keeping every pairing, setting and history. If our server is ever unreachable, Sandhi keeps working as it is.
Can teams and businesses use Sandhi?
Yes. One desktop can drive a whole floor of phones and tablets: a QA bench of real handsets, kiosks that reset themselves on schedule, or IT reach across sites. On-prem models and a self-hosted relay keep any third-party cloud out of the path. Talk to us about Enterprise.
How long does setup take?
About ten minutes. Install Sandhi on Windows and Android, pair the phone by scanning the code on your desktop and typing your password, then pick a model. How to use walks through each step.
