backchannel

Where Backchannel fits alongside Gong

This is not a "Gong alternative" page. Gong is the revenue record your team runs on after the call, and it is very good at that. Backchannel is a different layer: the live, seller-side assistant that runs on your own machine while the call is still happening, with nothing joining the meeting. If you already have Gong, this page is about what sits underneath it.

Not a Gong replacement · no bot joins the call · runs on hardware you control · MIT licensed

Two different jobs

Gong is built for after the call. Backchannel is built for during it.

This is a difference in design intent, not a defect in either product.

Gong owns the record

Gong's coaching documentation describes reviewing recorded calls: feedback requests, comments, call sharing, call scoring, and AI Call Reviewer. Deals, pipeline, forecast, and the call library all live there. More than 5,000 companies run on it.

The live surface is thin by design

The one live-call feature Gong documents is a manager listening in on or joining a call marked ON AIR, capped at two listeners. That is monitoring for a manager, not guidance for the person talking.

Backchannel owns the next sentence

An objection handler cycles every 10 seconds over the last 90 seconds of transcript and returns a response you could say in the next ten seconds, plus the underlying concern and the strategic angle behind it.

They do not compete for the same budget

Gong is an annual per-user contract with a platform fee, deployed org-wide by an admin. Backchannel is MIT-licensed software one person can run on a laptop. Adopting one does not displace the other.

The honest version

What Backchannel is not

Lead with the concession, because it is the whole reason this is an ecosystem page. Backchannel is not a revenue intelligence platform and cannot replace one. There is no CRM sync, no deal or pipeline object, no forecasting, no scorecards, no call library, and no team analytics. There are no user accounts, roles, or authentication of any kind -- the application has no user model at all, so there is no manager view, no permissions, and no way to roll a team up. If those are the things you buy Gong for, Gong remains the answer and nothing here changes that.

The second concession matters just as much. Backchannel ships a Privacy First mode that keeps everything on your machine, but the local transcription models cannot do text analysis -- so turning it on gives you fully local transcription and speaker diarization and turns off every live agent, including the objection handler. The realistic middle setting is local transcription with the interim audio gateway disabled: your audio never leaves the machine, while transcript text goes to Gemini or OpenAI on your own API key. That is meaningfully different from sending all your audio to a vendor, and it is not the same thing as "nothing leaves."

And to be clear about Gong: their published security posture is genuinely strong. Gong lets new customers choose US or EU data centers, publishes SOC 2 Type II along with ISO 27001, 27017, 27018, 27701, and ISO 42001 for AI management, states that your data is never used to train generative models, and commits to irreversible deletion within 30 days of a contract ending. We are not going to pretend otherwise to sell you something. The difference is architectural and it is about who the tool serves, not about anyone being careless.

The differences that actually matter

Nine agents, five of them live

Backchannel seeds nine agents. An audio gateway streams interim transcription. Five live insight agents read the transcript as it grows: a consolidated analyst on a 40-second cycle, the objection handler every 10 seconds over the last 90 seconds, a synthesizer with a 75-second cooldown that reconciles and answers open items, an opportunity specialist on a 55-second cooldown that matches openings against your own catalog, and strategic signals every 45 seconds producing the live signal, risk, next question, opportunity, and action cards. A further three-agent briefing pass runs after the call to settle the record. Each agent's model, prompt, and trigger is configurable, and you route them to Gemini or OpenAI on your own keys.

Real-time objection help is no longer novel. The mechanism still is.

As of July 2026 you can buy live in-call objection guidance from several vendors. Zoom took Sales Assist to general availability on 22 July 2026 inside Zoom Revenue Accelerator, surfacing "competitive intelligence, objection guidance, discovery prompts, battlecards, and configurable framework capture in real time" at $66 per user per month for Essentials and $99.99 for Premium, billed annually. That is a real product and we are not going to claim we invented the category. The difference is how the help is produced: Zoom's documentation has an admin configure the talking points for each topic ahead of time. Backchannel writes the response to the objection that was actually raised, from the last 90 seconds of what was actually said, and returns both an immediate reply and the underlying concern behind it. The honest trade is that pre-written guidance is deterministic and enablement-approved, and a generated response is neither.

Nothing to admit, nothing to eject

Gong's bot recording adds a virtual participant to the meeting, and with a waiting room enabled the host has to admit it. Bot-free capture exists, but only through native Zoom recording. Backchannel captures from a browser tab on your side of the call, so there is nothing in the participant list on Zoom, Meet, or Teams, nothing to admit, and nothing to remove if a prospect changes their mind mid-call.

Your recordings do not have to be a dead end

Backchannel appends each call segment to a WAV file on your own disk and serves it back over its REST API. Gong's public API has an add-new-call endpoint that accepts WAV, MP3, MP4, MKV, and FLAC files up to 1.5GB, intended for recordings from systems Gong has no pre-built integration with. So a pipeline from one to the other is architecturally straightforward. To be completely clear: no such integration ships in Backchannel today. Building it is your work, not a feature you can turn on.

Who should use which

Gong is the right tool when you...

Run a revenue team and need CRM hygiene, pipeline and forecast, scorecards, a searchable call library, talk-time and team analytics, coaching workflow, 70+ languages, and compliance attestations procurement recognizes. Nothing on this page is an argument against any of that.

Add Backchannel underneath when you...

Want help while you are still talking rather than a review afterwards, take calls where a recording bot is a liability, want the audio to stay on hardware you control, or are one person who cannot buy an org-wide platform contract to get a little help on a hard call.

What running both looks like

Nothing about Backchannel touches your Gong deployment. Gong keeps recording the way it already does, through its bot or native Zoom recording, and your team's record stays intact. Backchannel runs on your own machine and captures from your browser, so the two do not contend for the meeting or for the audio device. Setup is a git clone and docker compose up --build plus a Gemini API key, or a desktop build, or a local ONNX Whisper or Parakeet model if you want transcription to stay offline. The quickstart is upfront about the friction: the first start builds images and downloads models, so plan for a few minutes rather than seconds.

Past conversations can come in as transcripts (.txt, .md, .docx) or audio (.mp3, .m4a, .wav, .ogg, .flac) and be analyzed after the fact. There is no automated Gong export migration, and there is no Gong connector -- see the note above about what is and is not shipped.

Common questions

Does Gong give real-time coaching during a call?

Gong's own coaching documentation describes reviewing recorded calls: feedback requests, comments and tagging, call sharing, call scoring, and AI Call Reviewer. The only live-call feature Gong documents is a manager listening in on or joining a call marked ON AIR, capped at two listeners. Gong tells you about the objection after the call. Backchannel's objection handler runs every 10 seconds over the last 90 seconds of transcript and writes a response you could say in the next ten seconds.

Is Backchannel a replacement for Gong?

No, and we will not pretend otherwise. Backchannel has no CRM sync, no pipeline or forecast, no scorecards, no call library, no team analytics, and no user accounts or authentication of any kind. If your revenue team runs on Gong, keep running on Gong. Backchannel is the live layer on one seller's machine underneath it.

Can Backchannel recordings end up in Gong?

Architecturally yes, but nothing ships today. Backchannel writes each call segment to a WAV file on your own disk and serves it over its REST API, and Gong's public API has an add-new-call endpoint that accepts WAV, MP3, MP4, MKV, and FLAC files up to 1.5GB. Connecting the two is custom work you would build yourself. There is no Gong integration in Backchannel.

What does Backchannel cost next to Gong?

Gong does not publish prices; its pricing page says licenses are priced per user with a platform fee based on the number of users supported. Procurement data from Vendr puts the median Gong contract at $54,900 a year across 1,126 purchases, as of July 2026. Backchannel is MIT-licensed software that costs nothing: you pay for your own hardware and any Gemini or OpenAI API usage.
