# Knowledge sources — PDFs, text, Q&A, and website URLs
> Add PDFs, plain text, Q&A pairs, and website URLs to train your Agenvik agent. Includes plan limits, training quotas, and step-by-step instructions.
**Knowledge Sources** are the trusted content behind an Agent. Agenvik supports four source types: Text, Q\&A, PDF, and Website URL.
## What you will learn
* How to add each source type
* Which source types are available on your plan
* How to train ready sources
* How limits and deletion work
## Open Knowledge Sources
Open **Agents**, select an Agent, and find the **Knowledge Sources** card.
If the Agent has no sources yet, click **Add Source**. If sources already exist, click **Add**.
## Add a Text source
Use **Text** for policies, product notes, service descriptions, onboarding steps, and other rich text content.
1. Click **Add**.
2. Choose **Text**.
3. Enter a title that is easy to recognize later.
4. Add the content in the editor.
5. Click **Save changes**.
## Add a Q\&A source
Use **Q\&A** for high-confidence answers to common or sensitive questions.
1. Click **Add**.
2. Choose **Q\&A**.
3. Enter a title for the Q\&A group.
4. Add one or more question and answer pairs.
5. Click **Save changes**.
You can add multiple questions in one Q\&A source when they belong to the same topic.
## Add a PDF source
Use **PDF** for policy documents, product manuals, guides, and reports. Available on all plans.
1. Click **Add**.
2. Choose **PDF**.
3. Upload the PDF file.
4. Click **Save**.
Agenvik breaks the PDF into chunks and indexes the content. One PDF file counts as one knowledge source toward your plan limit.
## Add a Website URL source
Use **Website URL** to point your agent at a web page and have it automatically read and index the content. Available on **Starter and above**.
1. Click **Add**.
2. Choose **Website URL**.
3. Paste the full URL of the page.
4. Click **Save**.
Agenvik indexes the specific URL you provide — not the full site. To index multiple pages, add each URL as a separate knowledge source. Full site crawl is on the roadmap.
## Train sources
After sources are saved and ready, click **Train**. The training dialog shows your plan, daily limit, used runs, and remaining runs.
Training is disabled when:
* The Agent is locked
* No Knowledge Sources are ready
* The daily training limit has been reached
## Edit or delete a source
Click a source to edit it. Use the delete action when a source should no longer influence answers. Deleting a source is permanent and requires confirmation.
## Plan limits
| Plan | Knowledge sources | Training runs / day |
| ------- | ----------------- | ------------------- |
| Free | 10 | 3 |
| Starter | 250 | 10 |
| Growth | 1,000 | 20 |
| Pro | 5,000 | 40 |
PDF upload and plain text/Q\&A are available on all plans. Website URL crawling is available on Starter and above.
