Our take
Dia is an AI browser from The Browser Company, the team behind Arc. It puts a chat assistant in the address bar and a sidebar so you can ask questions about open tabs, and lets you build reusable "Skills" from plain-language prompts. Free to use; Pro is $20/month for unlimited AI. macOS only for now.
Best for
Mac users who want an AI assistant built into the browser to summarize, compare and act on what's already in their tabs.
Pros
- Chat directly with your open tabs
- Custom "Skills" from natural-language prompts
- Chromium-based, so the web just works
- Free tier covers everyday use
Cons
- macOS only at the moment
- AI-browser space is getting crowded
- Arc's wind-down makes some users wary
How it compares
Like Comet in our catalog, Dia bakes an assistant into the browser; Dia's angle is reusable Skills and tab-aware chat rather than full task automation.
Full review
Dia is the follow-up to Arc from The Browser Company, built on Chromium with a large language model wired into the omnibox and a right-hand sidebar. You can ask it about the contents of your open tabs, have it draft or summarize without leaving the page, and create "Skills", reusable shortcuts you describe in plain language, like a clean reading mode or an email summarizer.
It's free for everyday use, with Dia Pro at $20/month for unlimited chat and Skills, but it's macOS-only today. The bigger question is staying power: AI browsers are suddenly crowded (Comet and others), and Arc's wind-down left some users cautious. Atlassian's acquisition of The Browser Company gives it backing, but it's still early.

NotebookLM
Google's source-grounded research assistant: upload docs, PDFs and links, then ask questions, generate study guides, and turn sources into audio and video overviews. The free tier is genuinely usable; Plus raises the limits.
OpenRouter
OpenRouter is a unified API and marketplace for large language models. With one account and key you can reach 300+ models from OpenAI, Anthropic, Google, Meta, Mistral, Cohere and many smaller providers, using an OpenAI-compatible interface. It charges passthrough rates (provider cost plus a small markup) and publishes live pricing and usage-based model rankings, so you can compare options and route to the cheapest, fastest or most reliable one. It supports automatic fallback across providers and a free-model tier for experimentation; the main costs to watch are a 5.5% credit-card fee, which hits small top-ups hardest, and a 5% bring-your-own-key fee on requests above one million per month.
Gamma
AI design tool that generates polished presentations, websites, documents, and social graphics from a prompt or outline.
Krisp
On-device AI that cancels background noise on any call and records, transcribes, and summarizes meetings with accent conversion.
