The Merge: Why Building AI Chat Is Harder Than It Looks

CodeRabbit’s The Merge features Simon Farshid, founder and CTO of Assistant UI, an open-source React library that provides customizable AI chat and agent interfaces while managing complex functions such as streaming, conversation state, attachments, editing, voice, and agent-backend connections. Created from Farshid’s own repeated need for a reusable chat interface, the project has expanded to more than 2,000 open-source GitHub repositories and 1.4 million monthly npm downloads. Farshid emphasizes that the main challenge in AI chat products is not the visible chat box but the underlying state management needed to support streaming content, user interruptions, edits, files, and voice interactions smoothly. He argues that coding agents can complete much of implementation quickly, but the remaining work depends on product taste, API design, careful interaction choices, and validation in customer codebases. His workflow pairs coding agents with CodeRabbit findings, allowing agents to resolve clear review issues automatically while escalating uncertain ones for human judgment, alongside overnight automated checks that keep documentation current.
