How it works

Three steps. Zero rollout.

Onboard a brain in three minutes. No IT ticket. No migration. No per-seat math.

Step 01

Upload.

Build your secure Catalogues. Feed your private workspace with documents, images, notes, and spreadsheets. Sebtember strips them of human-readable text on ingest.

Security & infrastructure

Built on Google. Sealed by us.

Three guarantees. No asterisks. No exceptions.

Sealed by design

Documents are stripped of human-readable text on upload. Indexed for retrieval, never readable in transit or at rest.

AES-256 · Zero-text storage

Google-grade infra

Built on Google's enterprise infrastructure. Powered by Gemini 3. Your data never trains the model.

GCP · SOC 2 Type II

Kill switch

One click and the Catalogue is permanently wiped. No backups. No recovery. No exceptions.

Hardware-key revocable

Sebtember runs on Google Cloud. Powered by Gemini 3. Your data never trains the model.

Built for

Yes — if any of these sound like you.

Sebtember was built for the seven sentences below. If two of them sound like a Tuesday at your company, you're our customer.

“I need instant answers from my organization's internal data.”
Stop paying your team to manually search through scattered reports. Sebtember turns your private documents into a conversational AI. Because it never uses the public web, every answer is backed exclusively by your own data.
“I need absolute data security and strict access control.”
Your data never leaves your control. Built on Google's enterprise-grade infrastructure, Sebtember strips your documents of human-readable text upon upload. Admins enforce strict access through private Catalogues, and our Kill Switch ensures deleted data is permanently wiped.
“I refuse to pay for unused software subscriptions.”
Escape the AI subscription trap. Sebtember has zero monthly or annual fees. You only pay for the exact resources you use to generate answers. Best of all? It's completely free for your invited team members and clients.
“I want my entire team accessing instant insights without paywalls.”
Innovation dies when teams worry about software costs. By removing the per-seat paywall for invited users, you grant your entire workforce the speed and clarity of AI. They get the freedom to explore; you keep your budget under control.
“I want to close deals faster by letting prospects talk to my materials.”
Move beyond static PDFs and passive newsletters. Allow potential clients to chat directly with your service catalogues and proposals to get instant answers. It is next-generation educational marketing that builds instant trust — with zero new content creation required.
“I want to offer my clients a VIP, AI-powered support experience.”
Stop the endless back-and-forth email chains. Share your content directly with clients via a private Catalogue, giving them a conversational tool for instant answers. They save time. You look like an industry pioneer.
“I need an enterprise tool with zero onboarding friction.”
Forget the massive IT rollout. Sebtember has no learning curve. Users sign up via an Invite Code and are instantly connected to shared Catalogues. The interface is intuitive on day one, revealing advanced features only as needed.
