Integration details
Description
InsightSignal is a private, multi-source-verified knowledge graph for B2B company and contact intelligence. Every data point in a user's workspace is verified by two or more independent sources (AI analysis with live web grounding, professional-network data, web search, and email/phone validators), carries a numeric confidence score, and links to the citation page where the value was verified. With this plugin, ChatGPT can query the user's own verified data: search and filter companies and people, read company profiles with A-F quality grades and operational status, pull contact details with email deliverability and phone validity scores, summarize multi-source research reports with verdicts and evidence links, explore business relationships in the knowledge graph (competitors, partners, subsidiaries, key people), compare companies side-by-side, and track how verified data changed over time through immutable snapshots. Users can also trigger actions with explicit confirmation: verify a new company through the multi-source pipeline, generate or refresh research reports, enrich contacts, re-score companies against a stated business intent (sales prospecting, competitor analysis, partner fit, investment screening), and push verified records to their connected CRM. All data is strictly scoped to the signed-in user's InsightSignal account and organization. The plugin never exposes other users' data, and paid actions always present a cost estimate and require confirmation before executing.
