Free AI Chatbot for Your Website: No Code Required
Add a document-powered AI chatbot to your website for free. Upload your docs, customize the look, paste one line of code. Forever free tier included.
Most "free AI chatbot" tools give you a generic bot that makes things up. Or they're free for 14 days, then $49/month. Or "free" means a chat widget with their logo that links to their pricing page.
Here's a different approach: a chatbot that actually reads your documents and answers from them, with source citations so your visitors can verify the answer. And a free tier that stays free.
What makes this different from ChatGPT on a website?
ChatGPT answers from its training data. If someone asks about your specific return policy, PTO rules, or product specs, it guesses or says "I don't have that information."
A document-powered chatbot answers from your documents. Upload your FAQ, product guide, or employee handbook, and the AI retrieves the relevant passages before generating an answer. The visitor sees which document the answer came from.
The difference:
| Feature | Generic chatbot | Document-powered (Ask360) |
|---|---|---|
| Answers from your content | No | Yes |
| Source citations | No | Yes, with document names |
| Confidence scoring | No | Yes (Verified/Grounded/Mixed/AI Generated) |
| Stays on topic | Sometimes | Yes, grounded in your docs |
| Makes things up | Often | Flags when unsure |
The free tier
No credit card. No time limit. No "trial period" that quietly charges you.
| What you get | Free tier |
|---|---|
| Projects | 1 |
| Documents | 2 |
| Storage | 5 MB |
| Queries per month | 100 |
| Custom branding | Yes |
| Source citations | Yes |
| Confidence badges | Yes |
| Embed widget | Yes |
| Duration | Forever |
100 queries per month is enough for a personal site, small business FAQ, or a proof of concept before upgrading.
Setup in 4 steps
1. Sign up
Go to ask360.app/site/signup. Email, username, password. No credit card form.
2. Upload documents
Click Create Project, then Documents. Upload a PDF, Word doc, spreadsheet, or paste a URL. The system extracts the text, splits it into searchable passages, and builds a vector index.
3. Customize
Set your brand colors, logo, welcome message, and system prompt. Or click Generate with AI and let the system create a system prompt and suggested questions from your documents automatically.
4. Embed
Go to Publish and copy the one-liner:
<script src="https://ask360.app/widget.js" data-project="your-slug"></script>
Paste it before </body> on your website. A chat bubble appears. Done.

When to upgrade
The free tier handles the basics. Paid plans add:
