Ghost Mic
Real-time fact-checking for podcasters, while you speak
Ghost Mic listens while you record and fact-checks what you say in real time — cards appear on screen in a few seconds, powered by Cerebras Inference. Unlike meeting assistants (Otter, Granola) that summarize after the call, Ghost Mic works during the conversation. No bot joins your call. It transcribes live, catches checkable claims, searches the web, and shows you a citation — while you keep talking. If it can't ground a claim, it stays silent. Audio is never stored. Free while in beta.
Hey Product Hunt! 👋
I podcast about AI, and every episode the same thing happened: someone says "I think GPT-something scored 80-whatever on that benchmark…" and we'd either stop the show to google it, or hope we were right and fix it in post.
So I built Ghost Mic. It listens while you record and fact-checks you in real time. When you state something checkable, a card slides in — headline, context, clickable source — usually in under 2 seconds. You glance, correct yourself on air (or smugly confirm you were right), and keep talking. No bot in your call, no hotkey, no pasting transcripts into ChatGPT after the fact.
What it does today: 🎙️ Live transcription while you speak ⚡ Fact-check, context, and definition cards in ~2 seconds, each with a source and confidence score 🔇 Tuned to bias toward silence — better to miss five cards than show one bad one 🔒 Audio processed in memory only, never written to disk
It's a free beta and currently single-speaker — multi-host sessions and a "show prep" mode (episode notes → researched rundown) are next on the list.
Would love brutal feedback from anyone who podcasts, streams, debates, or argues with friends: when you're mid-conversation and unsure about a fact, what do you actually do today?
I'll be here all day answering questions!
