PAI Workstation
Every channel. Every model. Your own AI assistant. One app — as easy as pie, as smart as a team. Available for macOS and Windows; iOS and Android are not yet available.
The aggregation problem
Your channels live in five apps, your AI lives in another three, and your calendar and to-dos live everywhere else. Setting any of it up means accounts, API keys, and documentation. PAI Workstation ends the scatter: messaging channels and email flow into one unified inbox, every AI model sits one switch away, calendars and to-dos live in the same window — and none of it needs a manual, because PAI, the built-in AI assistant, sets everything up for you when you just say what you want.
Talk to PAI — it does the wiring
The heart of PAI Workstation is PAI, your conversational AI assistant — a cute avatar with nine living expressions that reacts as it works. Tell it what you need in one line: "configure an OpenAI-compatible model," "connect my Telegram bot," "remind me to follow up before 6pm" — and it gets done. No model lock-in: connect any OpenAI-compatible endpoint, and PAI orchestrates the models you choose like an expert team.
As easy as pie — complexity left to the system
The whole interface is three things: one chat box, one to-do list, one calendar. No third-level menus. Tell PAI "configure a model" and you are set — no manuals.
An expert team of models, in one chat
One chat box, many brains: a controller model breaks the task into steps and hands each to the model that does it best — architect, builder, reviewer — then delivers one answer. Every output carries a role-and-model badge, and every run is logged and auditable. Aggregated subscription endpoints (one key, many models) work with a single config.
No model lock-in, local-first
BYOK: connect any OpenAI-compatible endpoint, and PAI never takes a cut of your AI usage. Credentials stay on your machine — 0600 encrypted, never echoed in the UI, never uploaded. Conversations never leave the device.
One app for the whole workday
WhatsApp Business, Telegram (personal accounts and bots), LINE, and email (IMAP/SMTP; Gmail/Outlook via OAuth) flow into one unified inbox. Calendars aggregate read-only in one view; to-dos are created and checked off in chat.
Native, not a wrapper
A real Mac app: Swift shell + local engine, instant start, works offline. Upgrades snapshot automatically and separate data from program — zero loss across updates. Auto-updates ship with SHA256 integrity checks.

One-time purchase — US$9.90 per device
A PAI Workstation license is a one-time purchase of US$9.90 per device: use the current major version for the product lifetime. Free upgrades to future major versions are not promised; when a major version retires, updates and support may no longer be provided, and your purchased license remains valid. Payment is handled online through a secure payment provider (credit card, Apple Pay, Google Pay, and more); prices exclude applicable taxes, and VAT/GST (if any) is calculated at checkout. Activation keys are delivered to your purchase email address (never displayed on the website). Refunds: full refund within 14 days if the license has not been activated; after activation, EEA/UK consumers lose the statutory right of withdrawal (see the purchase page / Terms for details). AI runs on the models you bring (BYOK) — your keys stay local, and PAI never takes a cut.

I only have one AI subscription — can I still use the pipeline?
Yes. With a single model configured, it plays every role; you can assign different models to different roles at any time. Aggregated subscription endpoints (one key, many models) work too — fill in the config once.
Is my API key safe?
Keys stay on your machine with 0600 encrypted permissions, are never echoed in the UI, and are never uploaded to any server.
Which messaging channels are supported?
WhatsApp Business, Telegram (personal accounts and bots), and LINE direct connections; email via IMAP/SMTP and Gmail/Outlook browser authorization (OAuth).
