Sync your WhatsApp and LinkedIn messages to your CRM, surface powerful analytics on every conversation, and move faster with reusable snippets — two channels, one native window.
The deck arrives in a WhatsApp thread about padel. The warm intro lands in a LinkedIn DM. Terms get hashed out across two apps, between messages of gossip. None of it reaches your CRM — so weeks later you're rebuilding the relationship from memory.
Every other “WhatsApp CRM” or LinkedIn tool bolts onto a reverse-engineered API — and those get numbers and accounts banned. Backchannel doesn't. Under the hood it runs the official web.whatsapp.com and linkedin.com/messaging inside Apple's WebKit, the same engine as Safari. To WhatsApp and LinkedIn, you're just a person on the web client. Nothing automates, bulk-sends, or scrapes in the background.
WhatsApp Web or LinkedIn fills the window; Backchannel docks a native inspector on the right. It reads the open chat back to you — who this is, their CRM record, what's already filed — and files the line that matters in one keystroke. No tab-switch, no copy-paste, no “I'll log it later.”
A matching phone, email, or LinkedIn profile is an exact match — 100%, ready to link in one click. A fuzzy name is only ever suggested, scored, and shown to you — never silently filed on a stranger. A contact you reach on both WhatsApp and LinkedIn stays two distinct threads, never merged by accident. The basis is always visible, so you see why it linked, not just that it did.
Share a chat — or one message, from WhatsApp or LinkedIn — and it lands as a note on the matching contact or company, timestamped and attributed in your CRM's own voice, with the channel it came from. Every message is written exactly once, deduped by a sync key, so a thread is always a single, current note instead of thirteen ragged duplicates. Sync twice, switch Macs, re-link a record — still written once.

A Raycast-style command palette on ⌘K runs everything — sync, snippets, exports, navigation — without touching the mouse. Flip between WhatsApp and LinkedIn with ⌘1/⌘2, instantly, without either session dropping. Saved snippets drop into the composer; you still hit send. It's the client a power user would build for themselves.
Sync a chat — on WhatsApp or LinkedIn — and Backchannel charts its dynamic from the messages themselves: who leads, who has the last word, the tone and warmth, what you talk about, and how much has actually reached your CRM. No background reads, no fabricated calendar — just the conversation you already have open.
It's the WhatsApp and LinkedIn you already live in, with the native edges the web tab never had — notifications, calls, and the small controls that add up over a day.
Real macOS notifications, bridged straight from WhatsApp Web and LinkedIn.
Mic and camera pass straight through, so WhatsApp calls just work.
Both your WhatsApp and LinkedIn sessions stay live in the background, with a nudge when the open chat goes stale.
Always on top, Do Not Disturb, ⌘L to blur the screen, ⌘F to find, ⌘± to zoom — plus start a WhatsApp chat from a number.
Flip a chat to Shared and every new message files itself, hands-off.
Inline CRM search, plus one-click create when there's no match yet.
Pick your CRM of record per workspace; switch later and history re-syncs.
Tells you the moment a new version ships — one click to update.
One license covers your laptop, your desktop, and the spare.
Most tools ask you to trust a toggle. Backchannel makes the separation a fact of the system — every thread is born private, and the sync gate lives on the server. Even if a sync ran this instant, a private message would be refused before it left your Mac.
Every thread starts closed. New ones too. Imported history arrives private and stays that way.
Push a whole conversation as the record, or surface a single line. The other twelve messages never move.
The gate is server-enforced. Private content can't sync by accident, by cron, or by bulk action — the write is refused before a note is created.
private message → sync refused before any note is written.
Your padel banter. The contact who vents. The person who tells you something in confidence. The noise stays with you, and only the signal you choose ever leaves. That's not a privacy policy — it's how the product is wired.

Straight answers — the first three open by default, so a skim gets the reassurance instantly.
Yes on both counts — Backchannel is a real macOS app (Apple Silicon or Intel), not a browser tab. It wraps the official WhatsApp Web and LinkedIn messaging in one native cockpit; flip between them with ⌘1/⌘2 and both sessions stay live. The command palette, CRM sync, snippets, and relationship insights work the same on either channel.
Backchannel uses no unofficial API — under the hood it's the official WhatsApp Web and LinkedIn messaging running in Apple's WebKit, the same as using Safari. No Baileys, no LinkedIn Voyager scraping. It never bulk-sends, automates, or scrapes; you always hit send yourself, and it reads only the chat you have open when you ask. That's the lowest-risk profile there is. Wrapping any web app sits in a ToS gray area, so it's low-risk, not zero-risk — but your number and account are never driven by a reverse-engineered client.
