Your AI, your device, your rules

Your private AI assistant.

Pia

Only one hotkey away.

Use any AI model you want. Dictate with your voice — even offline. Your data stays on your device — or syncs to a server, ours or one you run yourself — end-to-end encrypted if you want it.

Beyond the hotkey

The heavy lifting.

Knowledge, meetings, agentic work, governance — the four pillars that make Pia more than a chat window. Each one runs where you decide: on your device, or on your server.

Knowledge over your own documents

Drop files in, ask questions, get answers with citations from your own material. A private vault on your device — or shared knowledge bases on your server, fed by a REST API.

Meetings & live transcription

Pia joins your Teams meetings, transcribes live, tells speakers apart, and writes the summary. Or transcribe the room around you — entirely on-device, behind a spoken consent gate.

Agentic work, under your control

Every tool Pia can use is a permission you grant — and can revoke at any time. Put recurring questions on a timer and the answers arrive as chats. Or hand Pia a whole goal: it plans, you approve the plan, it executes step by step while you steer.

Governance & security

Guardrails route risky requests to protected models. Groups carry policy — down to the model that answers. Audit logs notice anomalies. SSO, encryption at rest — and it all runs on a server you control.

The problem

Your AI assistant shouldn't spy on you.

Most AI tools send every conversation to servers you don't control, lock you into a single provider, and require a constant internet connection. Your data becomes their business model.

Your conversations stay on your machine

The app does not report back on what you do: no usage data, no tracking, no profile of you. What you write stays on your device until you send it out — by syncing, by asking a cloud model, or by reporting an answer. Turn on end-to-end encryption and everything you sync is encrypted on your device first — only your devices hold the key, not our server.

Switch AI providers without losing your history

Connect OpenAI, Anthropic, Mistral, Azure, OpenRouter, or your own model. Your conversations, memories, and templates stay with you no matter which provider you use.

Talk to Pia even without internet

Dictation and read-aloud run entirely on your device. For speech recognition you can pick Whisper or Parakeet, and the voice comes from Piper — three speech models, all running locally. Pia needs no internet connection for speech.

How it works

Up and running in three steps.

1

Download & install

Free, no account required. Installs in under a minute.

2

Pick your AI

Either use Pia Cloud models with no key at all — we run those on European providers — or connect your own account: OpenAI, Mistral, Azure, or any compatible provider.

3

Press your hotkey

Pia sits in your system tray. One hotkey brings it up — optimize text or chat.

Common questions

Your intelligence, your rules.

Is my data really private?

Yes. The Windows client is open source — you can audit every line that runs on your machine, and customers can request the full server source. Your conversations, memories and files stay on your device unless you send them out. Cloud sync is optional, and so is end-to-end encryption: turn it on and everything you sync is encrypted on your device first — only your devices hold the key, not our server. If you use a Pia Cloud model, your prompt passes through our server on its way to the AI provider, where it is processed and not stored. Bring your own provider and it never touches our server at all.

Is it hard to set up?

Not at all. Download, install, and a guided setup wizard walks you through provider configuration. You'll be using Pia in under two minutes.

What if I want to switch away?

Your data is yours. Everything is stored locally in standard formats. Switch AI providers anytime without losing a single conversation, memory, or template.
