Publishing a help center for your customers
Publish help articles to your end users at lettr.4os.ai/help/your-slug — pick a public slug, write articles in Markdown, and link from your support replies.
Lettr ships a built-in knowledge base so you can publish help articles to your end users. Articles render at lettr.4os.ai/help/<your-slug>/<article-slug> — no extra service, no DNS to configure.
1. Pick a public slug
From the dashboard, open Knowledge base (visible to owners and admins). At the top of the page, set your public slug — for example, acmecorp. Lowercase letters, digits, and hyphens; up to 40 characters.
The slug becomes the URL prefix for every article you publish. Owners can change it later, but doing so breaks any links you've already shared with customers, so settle on it early.
2. Write your first article
Click + New article. Fill in:
- Title — used as the page heading and SEO title.
- Slug (optional) — the URL piece after your public slug. Auto-generated from the title if left blank; override if you want a shorter URL like
installinstead ofhow-to-install-the-widget. - Category (optional) — a free-text label that groups articles on the index page (e.g. "Getting started", "Billing").
- Body — Markdown. Headings, lists, links, code blocks, tables, and task lists are all supported. Toggle Show preview to render as you type.
Hit Publish when you're ready. Switch to Draft at any time to take an article down without deleting it.
3. Link to articles from support replies
Once published, each article has a permanent URL. Copy it into a canned reply, paste it into a chat conversation, or add it to onboarding emails. Common pattern:
Hi! Here's how to install the widget on your Shopify theme: https://lettr.4os.ai/acmecorp/install-the-widget. Let me know if you hit any issues!
What it looks like to your customer
Customers visiting the URL see your team's articles on a clean page branded with your enterprise name. No Lettr login is required — these pages are intentionally public and unauthenticated.
Editing or deleting an article
From the Knowledge base tab, click any article in the list. Edit and save, or click Delete for a permanent removal. Deletes propagate to public visitors within 60 seconds (we edge-cache the public pages so a single tenant's traffic spike can't slow the rest of the platform).
Roles
- Owners — set the public slug, manage articles.
- Admins — manage articles. The slug is read-only because changing it breaks every URL the team has shared.
- Agents — no access to the KB tab. Use a published URL like any other customer-facing link.
Privacy and indexing
Help-center pages are marked noindex for search engines by default — your articles are your content, not ours, and we don't promote them in Google search results. If you want a specific article ranked, link to it from your own site or marketing channels; search engines will pick it up via your own backlinks.
