Chorus watches TikTok and reads Reddit for you. Ask a question, and about a minute later you get what people are actually saying, and which advice they actually back up. Free, private, all on your own Mac.
Every answer shows who said it, how much the comments back it up, and what to be skeptical of, so you can tell solid advice from confident nonsense.
"Go 1‑to‑8, coffee to water, and cold-steep it 16 hours in the fridge, anything shorter and it's watery."
"I run a 1:7 concentrate then cut it with water to taste."
"Cold brew in 5 minutes, no waiting."
Ask in Claude: best cold brew ratio, carry-on luggage that survives, whether that viral cleaning hack works. Here's what happens on your Mac, start to finish, in about a minute.
Chorus searches TikTok and Reddit the way you would, straight from your own computer. No account, no sign-in. Views, likes, and upvotes are easy to fake, so it also weighs whether the poster knows their stuff and whether the video or thread actually answers your question.
It listens to what's said in each video, even the ones without captions, and reads the Reddit threads end to end. All of that happens on your Mac; nothing gets uploaded anywhere.
The comments are where the truth comes out. Advice hundreds of people back up counts for more than a claim the comments are laughing at.
You get a summary you can trust, right in your conversation: who said what, how much people back it up, and what to be skeptical of.
Ask for the viral formats in any niche. Chorus ranks videos by outperformance: views measured against the creator's follower count, so a 2k-follower account pulling 3M views stands out from a celebrity coasting on reach. Every outlier comes with its hook, word for word, plus the sounds and hashtags the niche is riding right now.
For the technically curious: Chorus is a local MCP (Model Context Protocol) server, written in Python, that hands Claude ten research tools. TikTok and Reddit don't offer this data, so every capability is engineered on-device: the scraping, the speech-to-text, the ranking. Nothing is rented, so nothing costs money.
Your question, every caption, and every transcript are embedded as vectors by a MiniLM sentence-transformer and compared by cosine similarity, so “best budget espresso setup” matches videos that never use those exact words. If the model can't load, ranking falls back to lexical BM25.
Creator-written captions are used when they exist. Otherwise the audio is extracted and transcribed by Whisper on the Apple-silicon GPU, with a CPU fallback on other machines. No audio leaves the machine.
Top comments pass through sentiment analysis, and debunk language (“fake”, “scam”, “cap”) counts against a claim. That's the corroboration signal above: advice many people confirm ranks ahead of claims the comments dispute.
The result is an info bank, not a webpage: ranked claims with per-signal trust scores, full transcripts, and comment receipts, delivered over MCP so Claude can weigh the evidence and cite it.
There's no company server in the middle. What you ask, and what comes back, never leaves your own computer. There's simply nowhere else for it to go.
No subscription, no account, no hidden meter. If you own a Mac, you already have everything it needs.
No new app to learn. Connect it once and just ask questions the way you already do. Chorus quietly does the legwork behind the scenes.
Every claim comes with a read on whether real people back it up, so you can tell solid advice from confident nonsense.
The app comes with everything built in and connects itself to Claude. Comfortable in a terminal? You can also run it from the source code.
Drag Chorus to Applications and open it. The setup window walks you through it, including one click to add the MCP to Claude Code.
Clone the repo, install the browsers once, and register the server with Claude Code:
# one-time setup uv run playwright install chromium firefox # register with Claude Code claude mcp add --scope user ask-chorus \ -- uv run --directory /path/to/repo \ ask-chorus
Yes. Your questions and answers stay on your Mac. The only thing that leaves your computer is the same kind of traffic your browser sends when you browse TikTok or Reddit yourself. There's no company server in the middle, and nothing for anyone to log.
Yes. No account, no subscription, no hidden usage meter. It runs on your Mac's own internet and processing power, so there's nothing to charge you for. (If that ever changes, it'll be opt-in and obvious.)
The straight answer is no. Both platforms' terms of service restrict automated browsing, even of public posts. Chorus only reads public videos, threads, and comments, from your own connection, but you should know that before you use it.
A Mac and the Claude Code CLI (the Claude desktop app works too). Newer Macs (Apple silicon, 2020 or later) are fastest at the listening step; older Intel Macs work but take longer. A typical question takes about a minute to answer.
