Decagon vs OpenAI

A/B-testing suite for AI support agents: structured experiments (tone, logic, flows) against live traffic with control groups, statistical-significance testing and gradual rollout.

Dashboards and natural-language querying ('Ask AI') over support data: CSAT/deflection performance tracking, heatmaps, customer-journey visualization and knowledge-base performance.

Analyzes support conversations to detect gaps in a company's help center and auto-generates draft articles, ranked by impact, with monthly updates.

Integrated testing suite (internally called 'Simulations') that validates AI-agent behavior across channels before production deployment.

Always-on monitoring and QA for AI and human agent interactions against custom quality criteria.

Builds and runs customer-support agents that resolve enquiries over chat, email and voice.

Decagon's chat channel — an AI agent that handles live customer conversations in a web or in-app chat surface.

Decagon's email channel — agents that read and answer customer email threads rather than routing them to a queue.

Decagon's voice channel — an AI agent that answers customer phone calls in place of a hold queue.

Decagon's authoring layer for the rules an AI support agent follows, so non-engineering teams can build, iterate on and scale agents.

An AI partner built into Decagon that helps teams build and improve support agents — distilling best practices from hundreds of Decagon deployments into guidance for the builder, and auto-tuning the agent via "Duet Autopilot," which improves it with every conversation it handles.

Assistant for chat, web search, file analysis and image generation, used in the browser and in desktop and mobile apps; developers can build custom in-chat apps for it via the Apps SDK, built on the Model Context Protocol.

OpenAI's agentic web browser. Deprecated on 9 August 2026, with its browser-based agentic capabilities moved into ChatGPT and Codex.

A version of ChatGPT that US government agencies deploy in their own Microsoft Azure commercial or Azure Government cloud, so the agency manages its own security, privacy and compliance.

ChatGPT in the Excel ribbon: builds and edits spreadsheets, formulas and formatting from plain-language requests, answers questions about what is in the workbook, and asks permission before changing it. OpenAI's own page bundles this with a separate ChatGPT for Google Sheets add-in; this record covers the Excel add-in only.

ChatGPT in the PowerPoint ribbon: creates new slides, rewrites and restructures an existing deck, and turns notes, documents or spreadsheets into presentation-ready content while keeping the output editable in PowerPoint.

ChatGPT in a Microsoft Word sidebar: drafts, revises and reorganizes the open document from notes or pasted source text, pulling in context from connected apps like Outlook, SharePoint, Google Workspace and Dropbox.

OpenAI's text-to-video product. The web and app experiences were discontinued on 26 April 2026; the API will be discontinued on 24 September 2026.

Coding agent that reads, edits and runs a codebase from the terminal, an IDE extension and the ChatGPT web app.

OpenAI's cybersecurity offering, bringing together frontier cyber models, Codex Security and partner workflows to find, validate and fix vulnerabilities, with an access-gated Daybreak Red tier for authorised vulnerability research and red teaming.

Enterprise platform for connecting AI agents to systems of record and running them under enterprise identity, access and observability controls.
