Backchannel is what we build when we build for ourselves — an SEO, GEO & AI studio that sweats the parts other people skip.
Every detail done right.
Backchannel records both sides of your call, transcribes it and works out who said what — all on your Mac. Then it writes clean, structured notes wherever you already keep them.
Other tools send a bot into your call and your audio to their servers. Backchannel does neither. It listens the way you do — through your Mac — and keeps the result yours. A private alternative to Granola, Otter and Fathom.
Nothing joins the meeting and nothing announces itself. Backchannel captures your Mac's own audio — both your mic and the people you're talking to.
Transcription, working out who spoke, and reading the names off the screen all happen on-device. Your conversation isn't uploaded anywhere to be understood.
Finished notes are written to a folder you choose — your notes app, your drive, your system — not trapped behind someone else's login.
Backchannel handles the mechanical parts so the meeting stays your focus.
Backchannel spots when a call starts and offers to record — or starts automatically, if that's how you set it up.
Your mic and the meeting audio are captured together, plus a screenshot whenever the shared screen meaningfully changes.
On-device, it turns speech into text and separates the speakers — using enrolled voices and the names on screen to label them.
A structured summary with decisions and action items is generated and saved to the location you picked.
Not just a transcript — the words, the people, and what was on the screen.
Speech becomes searchable text on your Mac, split by who was talking — no audio upload required.
Backchannel saves a screenshot each time the shared screen changes in a way that matters — so slides and demos are captured, not every idle frame.
It labels speakers using voices you've enrolled and the participant names shown on screen — so the transcript reads like a conversation, not "Speaker 1".
Detects when a meeting begins and ends, so you're not left with an hour of silence after everyone's hung up — or scrambling to hit record.
Notes are written by the model you choose — your own key, or a local model. Backchannel isn't tied to one vendor, and you decide what the transcript is sent to.
Ask what was decided three meetings ago and find it — your back-catalogue of calls becomes something you can actually query.
The reason it's called Backchannel: what's said in your meeting stays between you and your Mac.
Recording, transcription and speaker separation all run on your machine. Your voice isn't streamed to a server to be processed.
Notes use the model you configure — your own key or a local one. You decide what leaves your Mac, and nothing does by default.
Recording other people is a deliberate step, never silent. Backchannel keeps a human in the loop before anything is captured or sent.
Straight about the AI part. Transcription, diarization and screenshot capture are fully on-device. Writing the summary uses whichever language model you point Backchannel at — so if you choose a cloud model, the transcript goes to that provider under your own account. Pick a local model and it never leaves at all.
Backchannel is in active development. Leave your details and we'll tell you the moment you can try it — no spam, just the launch.
