What operators build

Silex is a platform, not a product.

Here is what businesses can run on it.
Every vertical ships with a Behavior Specification Guide.

01
Research Digest Services
Run a subscription where each reader receives regular summaries of papers curated to their interests. Replies shape future editions — the service learns what each subscriber finds worth reading.
02
Coaching & Advisory
Offer ongoing coaching or consulting delivered by email. The platform remembers stated goals, tracks progress, and keeps the thread coherent over months of correspondence.
03
Editorial Content Delivery
Publish long-form essays, briefings, and analyses tailored to each reader's preferences and reading history. Every edition builds on what came before.
04
Client Intake & Qualification
Automate the first stage of your sales process. Silex gathers the details you need and hands you a structured brief before anyone on your team reads a single email.
05
Knowledge & Policy Support
Give employees or customers a conversational way to navigate your policies and documentation. Routine questions are answered instantly; edge cases are escalated to your team.
06
Order & Request Handling
Let customers submit orders in plain language. Silex extracts the relevant details, asks for anything missing, and hands off a clean structured record for your team to act on.
How it works

From your perspective as an operator.

Step 01
Configure your service
Define what your service does, connect your data sources, and set the tone. Silex handles the email pipeline, conversation memory, and delivery infrastructure.
Step 02
Give subscribers an address
Your service gets a dedicated email address. Subscribers write to it exactly as they would to any correspondent — no instructions required.
Step 03
Silex runs the conversation
Incoming messages are understood and replied to. Every exchange is logged. Preferences are remembered. The service improves with each interaction, automatically.
What sets Silex apart

Built for decades, not product cycles.

01
Every conversation is remembered
Preferences, history, and context accumulate across exchanges. Replies improve over time without any manual intervention from you or your subscribers.
02
Full operator visibility
Every exchange is logged. You can see what was sent, why it was sent, and what the service understood — giving you the information you need to improve and audit your service.
03
Reliable by design
No message is lost. Tasks that take time run in the background and retry automatically on failure. The service keeps working even when parts of your infrastructure do not.
04
Human oversight, on your terms
Not every reply should go out unsupervised. Configure approval steps for any workflow — keeping automation fast where you trust it, and adding a human check where it matters.
05
Rock-solid foundations
Silex runs on mature, proven infrastructure built for decades of uninterrupted operation — the same stack that keeps global telecoms and financial systems running.

Behavior Specification Guides

Root-cause intelligence for your vertical.

Most conversational AI services are built by patching prompts when they break — edge cases discovered in production, fixes applied without record. Silex services are different. Each vertical ships with a Behavior Specification Guide: a document where every design rule is anchored to a real root-cause pattern, the fix applied, and the architectural reasoning that connects them. Instead of arbitrary instructions, we use grounded reasoning.

01
Client Intake & Qualification
How to gather structured information from informal email prose across multiple turns: extracting slots from scattered sentences, re-asking elegantly without frustrating the correspondent, and never treating a casual confirmation as authorization to proceed. Each principle traces to a documented failure mode.
02
Coaching & Advisory
How to sustain coherent memory and persona across months of correspondence: preventing re-asking for information already given, tracking stated goals without drift, and maintaining trust across long asynchronous threads where context is easily lost.
03
Order & Request Handling
How to extract structured order details from unstructured prose: handling mid-thread changes, multi-party input from CC'd correspondents, and graceful backtracking when fields are missing or contradicted. Every guardrail has a documented root cause.
