ChorusAsk one question and hear from ChatGPT, Claude, Gemini, Perplexity and Grok at once — then a model you choose cross-checks them all into a single merged report. It uses the accounts you already pay for. No API keys.
Type a question once. Chorus sends it to every model on its own site using your logins, then one chosen model merges the answers — flagging where they agree, where they conflict, and what only one of them said.
Grab the notarized universal .dmg and drag Chorus to Applications. It's free — no license key, no trial.
Log into the AIs you want, right inside the app like a normal browser. It reuses the subscriptions you already have.
Type a question, choose your models, and pick which one writes the final summary.
Watch each AI respond, then read the single merged report — or flip to Compare to see all five side by side.
Stop tab-hopping. Ask once and get ChatGPT, Claude, Gemini, Perplexity and Grok all working on it.
A model of your choice cross-checks the others, flags agreement and conflict, and writes a single merged report.
Chorus drives your existing logged-in subscriptions. No usage bill, no keys to manage.
Everything runs on your Mac. Your question goes only to the same AI sites you already use — never through us.

No. Chorus runs entirely on your Mac and talks only to the AI websites you already use. There's no Chorus account, no backend, and no telemetry — your run History stays local.
