SYNAPSE CHAT — AI ASSISTANT
An AI that doesn't just talk about your template. It edits it.
An AI assistant wired into the email editor — it reads your template, surfaces validation errors, and applies every change directly into the document.

Write templates faster. Fix errors instantly.
Writes new NLT from a description.
Tell it what you want. It writes valid NLT syntax — variables, conditionals, loops, currency formatting, filter chains — and inserts it into your template.
Detects validation errors. Fixes them in place.
The AI scans your template for NLT validation errors — unclosed conditionals, mismatched loop variables, invalid filter syntax. Error count and severity badges appear on the chat avatar.
Explains NLT syntax with working examples.
Ask how to format a currency, chain filters, or write a date comparison. The AI answers with working NLT syntax specific to your use case.
Not a chatbot. An editor integration.
Most AI assistants live in a sidebar. You ask, they answer, you copy-paste. Synapse Chat is different — it's wired directly into the editor through a real-time bridge.
It reads your template.
When the editor is open, the AI sees the current document content. It knows what variables you are using, which conditionals are open, and where your cursor is.
It applies changes directly.
When the AI writes a fix or generates new content, it injects the change into the editor. You see the template update in real time — no copy-pasting, no manual insertion.
It tracks validation state.
The AI monitors NLT validation errors and surfaces them as severity-classified badges (errors vs. warnings) on the chat avatar. You see the error count before you even open the chat.
1{the user's First Name, or "there"},23Welcome to Premium!4Your balance is {the user's Balance,5 formatted as currency}.
The bridge exposes three primitives: isEditorActive(), applyEditorAction(), getEditorDocument(). The AI reads the current document state, generates a structured action (insert, replace, delete), and the bridge applies it transactionally — the editor updates in place without a round-trip through the clipboard.
Three prompts. Three completed templates. No copy-paste.

What it does — and what it doesn't.
Not a general-purpose chatbot.
It writes and fixes NLT templates. It does not write blog posts, answer trivia, or have conversations about the weather.
Not a replacement for understanding your data.
The AI works with your contact fields and event attributes. If you do not have an "Orders" field on your contacts, the AI cannot fabricate one.
Not a black box.
Every change it makes is visible in the editor. You see exactly what was added, changed, or removed. Accept, undo, or modify — you stay in control.
