UK startup combines client-side privacy technology with unified access to six AI providers, 20+ models, and patent-pending innovations
LONDON — Jan. 1, 2026 — XEROTECH LTD today launched CallGPT 6X, a productivity-focused AI platform that processes sensitive data within the user’s browser before any information reaches AI providers. The platform combines client-side privacy filtering with unified access to six providers and over 20 models — including text, image generation, and text-to-speech — alongside intelligent routing, seamless context switching, and patent-pending innovations in editable artifacts.
Digital workers toggle between applications 1,200 times per day, with 40 percent of productive time lost to context switching between tools. Professionals juggle separate subscriptions for ChatGPT, Claude, Gemini, and Perplexity — copying outputs between platforms, re-uploading documents for simple edits, and losing conversation history with each switch. Meanwhile, 81 percent of consumers believe AI companies misuse their data, creating barriers to adoption for those handling confidential information.
CallGPT 6X was designed to eliminate that trade-off.
CLIENT-SIDE PRIVACY FILTERING
The platform detects and processes personally identifiable information within the browser before transmission to any AI provider. National Insurance numbers, payment card details, passport numbers, and other sensitive data are handled locally — ensuring GDPR and UK Data Protection Act compliance by architecture rather than policy.
SMART ASSISTANCE MODULE (SAM)
Rather than requiring users to manually select which AI model to use, SAM analyses each query and routes it to the optimal provider for the task. The system leverages Claude for complex reasoning, Gemini for multimodal tasks, Perplexity for research requiring citations, and GPT for general assistance — automatically.
CONTEXT-AWARE EDITABLE ARTIFACTS
Context-aware editable artifacts allow users to generate documents, code, and structured content that can be edited, saved, and shared while maintaining conversation context. Unlike standard chat interfaces that lose connection to generated outputs, CallGPT 6X enables iterative refinement across sessions. Users edit content in place, click send, and the system compares changes and adds them to context — continuing the conversation with full awareness of modifications.
PLATFORM CAPABILITIES
CallGPT 6X provides unified access to six AI providers: OpenAI (GPT-4, GPT-4o), Anthropic (Claude Sonnet, Opus), Google (Gemini Pro, Flash), xAI (Grok), Mistral, and Perplexity. The platform includes over 20 models spanning text generation, image generation, and text-to-speech. Additional features include real-time cost transparency showing exact cost per message before sending, seamless model switching mid-conversation without losing context, and team collaboration tools with usage analytics.
“Every AI platform today forces a false choice: powerful capabilities or genuine privacy,” said Noman Shah, Founder and CEO of XEROTECH LTD. “CallGPT 6X eliminates that trade-off. The platform processes sensitive data before it ever leaves the browser — not after, not in transit, not on someone else’s server.”
LEADERSHIP
Shah quit his job in 2021. The mission: build AI that is accessible, productive and doesn’t sell out its users. Three countries and four years later, CallGPT 6X is the result.
Shah is a Fellow of the British Computer Society — a distinction held by the top one percent of computing professionals. He holds nine US patents, several of which are cited by Microsoft, Apple, Amazon, and IBM. His previous work includes AIA — Video CallGPT, developed and demonstrated at STEP Conference Dubai in February 2023, one of the earliest applications offering real-time voice interaction with generative AI, predating similar capabilities from major providers. He also created VisionXI — Talking Eyes, an AI-powered accessibility application for students with visual impairments released in January 2025. Shah completed executive education at Harvard Business School and Oxford Saïd Business School.
Dr. Atif Naseer is Co-Founder, bringing a PhD in Machine Learning and over a decade of research in deep learning, crowd analytics, and real-time systems. Shah and Dr. Naseer first met in 2012 in Makkah, Saudi Arabia, where they built research infrastructure and a startup ecosystem together before reuniting to launch XEROTECH.
Hassan Karim is Strategic Advisor and Lead Investor, contributing experience as an entrepreneur, angel investor, and business architect based in London.
