Add customer support to your Replit app in minutes
You built it in the browser with Replit Agent and shipped something real. Now real users send real questions. HelpShelf is the AI agent that answers them — grounded in your own content, added with one script tag, and quiet until it genuinely needs you.
Can you add customer support to a Replit app?
Yes. An app you build and host on Replit is a standard web app, so you can add a full AI customer support agent to it in minutes with HelpShelf. You point HelpShelf at your live Replit app URL or docs so it learns your product, then paste one script tag into your app's HTML head (index.html). A support widget then appears on every page and replies with cited answers from your content, escalating to you by email or Telegram when it is not confident. A free Starter 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.
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 your docs) and HelpShelf reads your product to build a knowledge base in seconds. 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
Your users get instant, cited answers around the clock. You only get pinged when something truly needs a human, and every conversation lands in your HelpShelf inbox.
Built for how you shipped it
Fast to install. Grounded in your content. Quiet until it needs you.
Live in about five minutes
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, then replies with cited sources — it won't invent features your Replit app doesn't have.
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.
Escalates instead of guessing
When confidence drops, it hands the conversation to you over email or Telegram rather than making up an answer.
Free while you find users
Start on the free Starter 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
You shipped your first real, hosted app on Replit. Let an AI agent field the beginner questions so you can keep learning by building.
Students & class projects
Add a self-serve help agent to the project you're demoing or submitting — it looks polished and takes about five minutes to wire in.
Indie devs
Support that runs while you sleep or build the next thing. The agent handles the repetitive bulk of incoming questions.
Replit Agent MVPs
You prompted a product into existence and shipped it. Now answer the first wave of "how do I…" questions automatically.

Frequently asked questions
Yes. An app you build and host on Replit is a standard web app, so you can add a full AI customer support agent with HelpShelf in about five minutes.

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.
It escalates instead of guessing. When the agent isn't confident, it hands the conversation to you over email or Telegram and lets the user know a human will follow up. Every answer it does give is grounded in your sources with citations, so it won't invent features your Replit app doesn't have.
Yes. HelpShelf's Starter plan is free and includes a live widget, AI answers, and your own help center — plenty for most side projects and early MVPs. Paid plans start at $49/mo and are billed per resolved conversation, so you only upgrade once your Replit app is getting real traffic.
Yes. When you change features or copy and republish in Replit, re-sync your content in HelpShelf and the agent relearns from your latest version. You can also review held conversations and correct answers, which sharpens future responses.
