Hark vs Dia: which one should you use?
Dia, from the makers of Arc, is a beautifully designed AI browser — for recent Macs. Hark brings an AI agent to Chrome on any desktop. They also aim at different jobs: Dia helps you think with your tabs; Hark does tasks on them.
Choose Dia if you are on an Apple-silicon Mac and want an elegant browser for reading, writing and planning with your tabs. Choose Hark if you are on Windows, Linux or ChromeOS, want to stay in Chrome, or want an agent that actually clicks, types and books.

Platform decides it for most people
Dia runs only on Macs with Apple silicon. That rules it out for most of the world’s desktops. Hark runs wherever Google Chrome runs on desktop, so a mixed household or team can all use the same assistant.
Thinking partner vs errand runner
Dia is at its best as a thinking partner: compare these tabs, draft from these sources, brief me on my day. Hark is an errand runner: reply to this email, fill this form, book this table, remember this delivery. If you recognise your day in the second list, Hark will save you more clicks.
