Technology Lookup & Checker GPT

What is the purpose of Technology Lookup Checker GPT?

Technology Lookup Checker GPT (by TechnologyChecker.io) turns domains or keywords into actionable technology profiles. It identifies website stacks using multi-signal detection, connects stack signals to verified contacts, and adds 20-year historical intelligence to drive prospecting, competitive analysis, and conversion.

What are the key features?

• Technology Detection: Headless JS rendering, asset fingerprinting, HTTP header/DNS/TLS checks, and library/framework signatures with confidence scoring and ambiguity handling.
• Contact Intelligence: Entity resolution to surface decision-makers (role/department targeting), firmographics, social links, traffic markers, and an intent/stack-fit score.
• Historical Intelligence: 20-year stack timelines, vendor adoption curves, competitor diffs, cohorts, and historical exports (CSV/API).
• Alerts & Automation: Real-time stack change monitoring, one-click detection, bulk enrichment (up to 100k rows), CRM-ready export.

What can I do with it?

• Scan a single domain for a rich stack profile.
• Enrich large lists from CSV/XLSX and export back to CRM.
• Find decision-makers that match your ICP.
• Track competitor moves and spot market opportunities first.
• Build lead scoring models using intent keywords and stack-fit.

How does the scan work?

The GPT aggregates multiple signals (rendered JS, assets, headers, DNS/TLS, known signatures) and returns a confidence score per technology. When signals conflict, it flags ambiguity and suggests a quick verification checklist.

Who is it for?

• Sales/Marketing/RevOps: Better targeting, higher conversion, faster research.
• Competitive Intelligence & Product Marketing: Track stack changes, position against competitors.
• Growth & Ops Teams: Automate enrichment, alerts, and CRM workflows.
• Analysts & Researchers: Long-horizon adoption trends and cohort insights.

Does it verify contacts?

It surfaces decision-makers with verification steps when available. If an email can’t be verified, it’s labeled accordingly and alternative channels are suggested.

How do bulk lookups work?

Upload or paste domains (up to 100,000). The GPT processes in batches, returns a progress summary, and provides CSV/XLSX/API-friendly outputs with mapped fields for CRM import.
