Revenue Command Center
Every message triaged. Every reply drafted. Nothing sent without you.
Nexus OS reads every inbound customer message across Gmail, WhatsApp and Instagram, filters the noise, scores what it is worth, and writes the reply. You stay the last step.

Plugs into the channels your customers already use.
Supported integrations: Gmail, WhatsApp, Instagram, Messenger, IMAP / SMTP, Supabase, n8n, OpenAI.
The problem
Revenue does not arrive in a CRM. It arrives as a message you have not read yet.
A billing dispute in Gmail, an upgrade question in a DM, a churn signal buried under sixty newsletters. The deal is not lost because you said no — it is lost because nobody answered in time.

The protocol
Six steps between an unread message and a closed loop.
- 01
Discovery
Nexus watches your connected inboxes continuously. New messages arrive through OAuth and webhooks, not a nightly export, so nothing waits in a queue you forgot about.
- 02
Intake
A zero-cost filter drops spam, receipts and newsletters before any paid model runs. What survives is normalised into one shape, whatever channel it came from.
- 03
Rescue
Each surviving message is classified for intent, urgency, estimated value and churn risk — so an angry enterprise customer never sits below a cold pitch.
- 04
Approval
A reply is drafted in your voice using your own business context. Anything high-value or high-risk lands in your approval queue. You edit or approve in one click.
- 05
Execution
Approved replies go back out on the channel they arrived on. Every send is logged, idempotent and attributable, so the same message never goes twice.
- 06
Growth
The buy-back report closes the loop: what was rescued, what was drafted, and how much of your week the queue handed back to you.
Capabilities
Built as plain steps, not a black box.
Fetch, filter, classify, draft and send are deterministic. The only agent in the system is the read-only one you talk to.
Noise filter that costs nothing
Spam, receipts, calendar invites and newsletters are dropped by rules before a single token is spent. Your AI bill tracks real customers, not mailing lists.
Value-aware triage
Intent, urgency, estimated value and churn risk on every message.
Replies in your voice
Drafts are grounded in your own docs and past conversations — retrieval, not a fine-tune.
An approval queue you actually clear
One screen, one decision per message. Approve, edit, or reject — and the policy learns where you want the line drawn between auto-send and hard gate.
Unified inbox
Every channel normalised to one message shape, deduplicated on arrival.
Buy-back report
What the system rescued and drafted, summarised on a schedule you set.
Architecture
The boring guarantees, in writing.
These are properties of the system, not policy promises.
- 01Row-level tenant isolation
- Every row carries a tenant id and every table enables row-level security from the day it is created. One customer cannot read another's data.
- 02Encrypted third-party tokens
- Gmail and Meta credentials are AES-256 encrypted before they are stored. Service keys are server-only and never reach the browser bundle.
- 03Nothing sends itself
- Classifiers and drafters cannot send. Every outbound reply passes through the approval layer, where policy decides auto-send or a hard gate.
- 04Verified webhooks
- Inbound webhook payloads are signature-checked before they are trusted, and message ingestion is idempotent, so a replay cannot double-send.
- 05Your data stays in your database
- Embeddings live in pgvector inside the same Postgres as everything else. There is no separate vector service holding a copy of your conversations.
- 06No fine-tuning on your data
- Quality comes from prompts, examples and retrieval over your own documents. Your customer messages are not training data.
How it fits
Sits between your inbox and your team. Nothing to rip out.
Connect a mailbox with OAuth, point your Meta pages at the webhook, and Nexus does the rest. Workflows run in n8n, data lands in Supabase, and you keep both.
