Overview
The "ChatGPT effect" has rapidly replaced developers’ long-standing go-to solutions for problem solving, StackOverflow and Google search. Instead of manually searching for documentation, code snippets, or answers, developers can now chat directly with large language models (LLMs). However, generic AI cannot replace deep technical understanding.

| Source Coverage | Can it ingest docs + GitHub + Slack + other third-party sources? |
| Deployment Flexibility | Is it widget only? Or does it also support MCP, Slack, Discord, API? |
| Analytics and Insights | Can you find content gaps, track CSAT, and debug bad answers? |
| Enterprise Readiness | Does it meet requirements like SOC 2, SSO, and privacy controls? |
| Technical Depth | Does it handle code samples, API references, and version-specific answers? |
