Add customer support to your Replit app with one script tag
You built it in the browser with Replit Agent and shipped something real. Now real users send real questions. HelpShelf answers supported questions from your content, installs with one script tag, and stops clearly when it cannot verify an answer. With tested Telegram, the visitor can choose to send a handoff.
Can you add customer support to a Replit app?
Yes. An app you build and host on Replit is a standard web app. Point HelpShelf at your live Replit app URL or docs, then paste one script tag into the app's HTML head (index.html). The widget gives supported answers with citations; when it cannot verify an answer, it can offer a visitor-confirmed handoff only if your tested Telegram destination is reachable. The Free plan lets you launch support alongside your first hosted app at no cost.
Replit hosted your app. It did not hand you a support inbox.
Going from a prompt in Replit Agent to a live, public app is the fun part. Then strangers find the URL — and the questions start landing in your lap.
- First-time users hit the same setup snag and have no help center to read.
- Your personal email quietly becomes the support desk you never planned to staff.
- Replit Agent writes the code, but it can't answer "why won't my login work?" at midnight.
- You're adding features and fixing bugs, yet replying to every "how does this work?" by hand.
Answers that sell
You shipped it. Now it has to sell.
Most questions on a new Replit app are not support tickets — they are buying questions from visitors deciding whether to pay. HelpShelf answers them on the spot with cited answers drawn from your own content, nudges the hesitating visitor with a proactive teaser, and can offer follow-up after a confident answer. A lead is recorded only after the visitor submits a valid email. And because every HelpShelf site ships llms.txt and a live MCP server, the AI assistants your buyers use can inspect your product sources when those surfaces are linked or configured. Support questions? The same agent handles those too, included.
Sales mode where it counts
Auto-pinned to your pricing and marketing pages at onboarding — the agent sells there and supports everywhere else.
A nudge for the hesitating visitor
A proactive teaser bubble invites the question that is stopping them from signing up.
Leads, not closed tabs
After a confident answer the agent offers a follow-up — the visitor’s email lands in your dashboard and Telegram.
Sales Pulse on your dashboard
Sales conversations, captured leads, top buying questions, and AI-shopper traffic in one view.
From Replit build to live support in three steps
No help desk migration. No new platform to learn.
Point it at your Replit app
Paste your live Replit app URL or docs and HelpShelf indexes that content into a knowledge base. No source code or repo access required.
Paste one script tag
Add the HelpShelf snippet to your app's HTML head in index.html, then publish. The support widget loads on every page — no backend or extra service to wire up.
Let the agent run
Users can ask supported questions and inspect cited answers. When the agent cannot verify an answer, the visitor can confirm a handoff if your tested Telegram destination is reachable. Every conversation remains reviewable in your HelpShelf inbox.
Built for how you shipped it
Fast to install. Grounded in your content. Stops safely when it cannot verify an answer.
One script tag to install
Point it at your Replit app URL, paste the script tag, publish. No help desk to migrate and no infrastructure to stand up.
Answers from your own content
The agent learns from your live app and docs, cites the sources behind confident answers, and stops when it cannot verify a feature.
Just one script tag
A Replit app is a normal web app. Add the HelpShelf snippet to your index.html head and the widget shows up on every page.
Stops instead of guessing
When confidence drops, it hands the conversation to you through your verified Telegram connection rather than making up an answer.
Free while you find users
Start on the Free plan — built for the first Replit app you just shipped and the early users poking at it.
Keeps up as you ship
Change something in your Replit app and re-sync your content. The agent relearns from your latest version, so answers stay accurate.
Perfect for Replit builders
Whatever you shipped, your users will have questions
First-time builders

Frequently asked questions
Yes. An app you build and host on Replit is a standard web app. Add your live Replit app URL as a source, place one HelpShelf script tag in the app's HTML head, and publish. The widget gives supported answers from your content, with a Free plan to start.
Create a free HelpShelf account, add your live Replit app URL or docs as a source, customize the widget, and copy the embed snippet. In your Replit project, paste that script tag into the head of your index.html, then publish your app. The widget is then live for every visitor, with no backend to set up.
No. HelpShelf answers from your content — your live app, help docs, or pasted text — not your source code. If you've connected your Replit project to GitHub, you can optionally link that repo so the agent also learns from your README and docs, but it isn't required.
When the agent cannot verify an answer, it says so rather than presenting an invented feature or step. Every confident answer is grounded in your sources with citations. If your tested Telegram connection is reachable, the visitor can review and confirm a human handoff.
Yes. HelpShelf's Free plan includes a live widget, AI answers, and your own help center — plenty for most side projects and early MVPs. Pro starts at $49/mo with 10,000 AI searches and 2,000 AI chats each month, so you only upgrade once your Replit app is getting real traffic.
When you change features or copy and republish in Replit, re-sync and review the relevant content in HelpShelf. New answers use the updated published sources; conversation records and knowledge gaps show what needs attention.
