The problem

Five AI subscriptions. Data leaking into all of them. Tabs open all day.

1,200
app switches a day for the average knowledge worker.
40%
of productive time lost to switching between tools.
81%
of people believe AI companies misuse their data.

CallGPT 6X brings it all into one workspace, and masks personal identifiers before your prompt leaves the page.

Privacy by architecture

Identifiers are replaced before your prompt leaves your device.

NI numbers, card and passport details, NHS numbers and postcodes are detected and replaced in your browser. The model gets the rest of your prompt, with placeholders instead of the real values.

Questions

Everything you’d ask before switching.

Where exactly does my sensitive data go?
Identifiers such as NI, NHS, card and passport numbers and postcodes are replaced with placeholders in your browser before the message is sent. The rest of your prompt goes to the model provider you choose, which receives the placeholder, never the real value.
Can I switch models mid-conversation?
Yes. Move between models in one thread and your full context, every message and file, is preserved. No new chat.
How is this cheaper than separate tools?
One subscription replaces up to $60/month in separate subscriptions, and SAM routes each query to the cheapest capable model. Plans start at $9.99/month.
Who builds CallGPT 6X, and can I trust it?
Built by XEROTECH, a UK company and member of the Google for Startups, Microsoft for Startups, NVIDIA Inception and ElevenLabs Grants programmes, and a Claude Partner Network & IBM Select partner. NCSC Cyber Essentials certified, ICO registered, and the official AI platform of AIU.

20+ models. One bill. Your data stays yours.
