Assist
Features
Everything Assist does, from the answer your visitor sees to the controls you hold behind it.
Answering
What your visitors experience.
Grounded in your content
Answers are built from your pages and documents, retrieved fresh for every question. If your content doesn't cover it, Assist says so politely — it never fabricates facts, numbers, or policies.
Citations on every answer
Each answer links to the pages it was drawn from, as inline links and source chips. Visitors can verify anything in one click — and every citation is a visit to your content.
Streaming answers
Answers stream word by word, with the first words appearing in under a second. Repeat questions hit a per-site answer cache and return instantly.
Page-aware context
Assist knows which page the visitor is on. "What does this cost?" asked on a product page means that product — no clarifying round-trips.
Real conversations
Follow-ups work naturally, conversations survive closing the widget, and visitors can start a new conversation or revisit recent ones. Idle threads expire so stale context never pollutes a fresh question.
Instant search built in
Results appear as visitors type, before any AI is involved. One box covers both "find me the page" and "answer my question" — replacing your site search outright.
Your content, in
How Assist learns what it knows.
Content index from your build
Publish a small JSON index from your site build — generators for npm, Astro, Vite, Next, and GitHub Actions. Assist polls it and re-ingests automatically whenever your content changes. You control exactly what Assist knows.
Bucket ingestion
Point Assist at an Edge Storage bucket and drop documents in — markdown, plain text, HTML, PDF. Additions, updates, and deletions are picked up incrementally. Perfect for knowledge bases that don't live on a website.
Always in sync
Ingestion is automatic and continuous. Rebuild your site or update a document, and Assist answers from the new content — the answer cache invalidates itself on every re-ingest.
Up to 10,000 documents
Every site supports up to 10k documents with fast, predictable retrieval. Bigger knowledge base? Our Expert Services team builds custom deployments beyond the cap.
Insight & control
You own the answers.
Pinned facts
Short authoritative statements that take precedence over site content — "We ship worldwide except X", "Support hours are Y". One pinned fact fixes every phrasing of a question.
Curated Q&As
For high-stakes questions, write the exact answer yourself. Strong matches return your words verbatim — instantly, without an AI call.
Question log & correction loop
Browse every question visitors ask, see the answer given, and correct it in one click — the correction becomes an override. Your assistant gets better every week you use it.
Metrics & conversations
Questions per day, answer rates, latency, top questions, top unanswered questions, most-cited pages — plus a full conversations explorer to replay any thread.
Answer cache purge
Clear your site's cached answers whenever you need — the whole site or a single question — just like purging a CDN. Free and instant.
Budgets & caps
Free tier is hard-capped and can never bill you. Paid usage draws from a prepaid budget you set — when it's exhausted the widget falls back to plain search, never to a surprise invoice.
The widget
Fits your site, carries your brand.
Modal or embedded
Run Assist as a floating launcher, bind it to your own search icon or Cmd+K, or embed it inline in a help centre, docs sidebar, or 404 page. Same conversation state, different mounts.
Full-screen mode
On desktop, visitors can expand the widget to cover the page — chat on the left, a citations and links rail on the right. Or switch it off per site if you'd rather keep things compact.
Themable
Colours, position, placeholder text, welcome message — configured from your dashboard, applied instantly, no code changes. Configuration is server-side, so it can't be tampered with in the page.
White-label
Paid sites can remove Edge branding. The white-label add-on goes further: your own assistant name and icon throughout — your visitors meet your assistant, not ours.
Mobile apps
A hosted widget page drops into any in-app browser sheet today. Native SDKs for Swift, Kotlin, React Native, and Flutter follow — same content, same customisation, fully native UI.
Protected by design
The ask endpoint is guarded by Edge Shield and per-site rate limits, so bots can't burn your question budget. Private (bucket) sites use per-site keys.
Try it before you add it
