London, UK, Jan. 1, 2026 (GLOBE NEWSWIRE) — XEROTECH LTD today launched CallGPT 6X, a productivity-focused AI platform that processes sensitive data in the user’s browser before information reaches AI providers. The platform combines client-side privacy filtering with unified access to six providers and more than twenty models – including text, image and text-to-speech generation – along with intelligent routing, seamless context switching and patent-pending innovations in editable artifacts.
CallGPT 6X shows real-time cost tracking and seamless model switching – Claude Sonnet 4.5 responds after GPT-4.1 Mini, all in one call
Digital workers switch between applications 1,200 times a day, with 40 percent of productive time lost due to context switching between tools. Professionals combine separate subscriptions for ChatGPT, Claude, Gemini, and Perplexity: they copy output between platforms, re-upload documents for easy editing, and lose conversation history with each switch. Meanwhile, 81 percent of consumers believe AI companies are misusing their data, creating barriers to adoption for those who handle confidential information.
CallGPT 6X is designed to eliminate that trade-off.
CUSTOMER PRIVACY FILTERING
The platform detects and processes personally identifiable information in the browser before sending it to an AI provider. National Insurance numbers, payment card details, passport numbers and other sensitive data are processed locally, ensuring GDPR and UK Data Protection Act compliance through architecture rather than policy.
SMART ASSISTANCE MODULE (SAM)
Instead of users having to manually select which AI model to use, SAM analyzes each query and routes it to the optimal provider for the task. The system automatically uses Claude for complex reasoning, Gemini for multimodal tasks, Perplexity for research requiring citations, and GPT for general assistance.
CONTEXT-AWARENESS EDITABLE ARTIFACTS
Context-aware editable artifacts allow users to generate documents, code, and structured content that can be edited, saved, and shared, while maintaining conversational context. Unlike standard chat interfaces that lose connection to generated output, CallGPT 6X enables iterative refinement between sessions. Users edit the content on the spot, click submit, and the system compares the changes and adds them to context, continuing the conversation with full awareness of the changes.
PLATFORM OPPORTUNITIES
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 more than 20 models for text, image and text-to-speech generation. Additional features include real-time cost transparency that shows the exact cost per message before it’s sent, seamless model switching during the conversation without losing context, and team collaboration tools with usage analytics.
“Every AI platform today forces a false choice: powerful capabilities or true 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 afterwards, 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 – an award given to the top one percent of computing professionals. He holds multiple US and Canadian patents 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 first applications to provide real-time voice interaction with generative AI, predating similar capabilities from major carriers. He also created VisionXI – Talking Eyes, an AI-powered accessibility application for visually impaired students, released in January 2025. Shah completed executive education at Harvard Business School and Oxford Saïd Business School.
Dr. Atif Naseer is co-founder and has a PhD in Machine Learning and more than ten years of research in the field of deep learning, crowd analytics and real-time systems. Shah and Dr. Naseer first met in 2012 in Mecca, Saudi Arabia, where together they built a research infrastructure and startup ecosystem before reuniting to launch XEROTECH.
Hassan Karim is a Strategic Advisor and Angel Investor and brings experience as an entrepreneur and business architect based in London.
