# Syncing Content

> Keep your chatbot's knowledge base current with manual sync, bulk sync, and per-source auto-sync.

# Syncing content

When your website or documents change, your chatbot's knowledge base needs to be updated. InsiteChat offers **manual sync**, **bulk sync**, and **per-source auto-sync**.

## How syncing works

When a sync runs, InsiteChat re-crawls or re-processes your sources and compares the new content against what was previously indexed. Only pages or documents that have changed are re-processed. Content that hasn't changed is left as-is, so syncs are fast even for large knowledge bases.

## Manual sync

Manual sync is available on all plans, including Free.

<Steps>
  <Step title="Go to sources">
    Select your chatbot and click the **Sources** tab.
  </Step>

  <Step title="Find your source">
    Use the **search bar** to find a source by title or URL, or use the **status filter** buttons to narrow the list.
  </Step>

  <Step title="Sync">
    Click the refresh icon on the source card. The status changes to **pending** and then **crawling** as the sync runs.
  </Step>
</Steps>

## Bulk sync

Re-sync multiple sources at once:

1. Use the **checkboxes** to select the sources you want to sync
2. Click **Re-sync** in the bulk action bar
3. All selected sources are queued for processing

This is useful after a major website update when you want to refresh all URL sources simultaneously.

## Per-source auto-sync

When adding a URL source, you can set an auto-sync frequency for that specific source:

| Frequency   | Minimum Plan | How it works            |
| ----------- | ------------ | ----------------------- |
| **Never**   | All plans    | Manual sync only        |
| **Monthly** | Starter      | Re-crawls every 30 days |
| **Weekly**  | Growth       | Re-crawls every 7 days  |
| **Daily**   | Scale        | Re-crawls every day     |

<Note>
  You cannot select a frequency higher than your plan allows. A Growth plan user can choose monthly or weekly, but not daily. If you downgrade your plan, sources set to a higher frequency will fall back to the plan's maximum.
</Note>

### How auto-sync runs

* Auto-sync runs hourly via a background dispatcher
* Sources are staggered across the day to distribute load
* Only changed content is re-processed (incremental sync)
* The URL cache is bypassed during auto-sync to detect changes
* Trial users are excluded from auto-sync

## Plan-based defaults

If you don't set a per-source frequency, the plan default applies:

| Plan    | Default auto-sync |
| ------- | ----------------- |
| Free    | None              |
| Starter | Monthly (30 days) |
| Growth  | Weekly (7 days)   |
| Scale   | Every 3 days      |

## Choosing the right strategy

**Free plan:** Use manual sync after publishing major content updates.

**Starter plan:** Monthly auto-sync covers most use cases. Trigger manual syncs for time-sensitive changes.

**Growth plan:** Set frequently-changing sources (blog, docs) to weekly auto-sync. Set stable sources (about page, pricing) to monthly or never.

**Scale plan:** Daily auto-sync keeps your chatbot tightly aligned with your content. Use bulk sync for immediate updates across all sources.

## What gets re-processed

Only changed content is re-processed on each sync:

* **Website sources** — Pages where the text content hash has changed
* **New pages** — Discovered pages that weren't in the previous crawl
* **Removed pages** — Pages no longer accessible are archived from the knowledge base
* **Unchanged pages** — Skipped entirely for efficiency

## Failure notifications

If a source fails to sync after all retries, you'll receive an **email notification** with the error details and a link to the Sources page. You can then review the error, fix the issue (e.g., update the URL or check access), and trigger a manual re-sync.
