Dia is The Browser Company’s second act after Arc — AI-first, beta, opinionated. Egg ships an agent with skills, BYOK, a firewall, and a workspace layer that Dia doesn’t.

Dia is opinionated about how AI should fit in the browser. Egg is opinionated about giving you the controls — pick the model, write the skill, audit the action.
Anthropic / OpenAI / Google / OpenRouter / Ollama. Per agent, per task. Dia routes through The Browser Company’s cloud.
Drop a folder with a SKILL.md and tools. Egg picks it up. Dia’s capabilities are fixed.
Approval prompts, per-service rules, every tool call audited. Dia ships agentic features but not the controls around them.
Filesystem-backed projects, knowledge synthesis, scheduled monitors, contacts, publish. None of this is in Dia.
Three reading modes plus a feed extractor. Dia doesn’t ship reader modes.
If you want a polished, opinionated AI experience and don’t mind locked-in models, Dia’s UX is well-considered. It’s also Mac-only and beta — so it’s not really comparable on availability.
