# AI Assistant FAQ

> Answers to common questions about AI Assistant: how it differs from Octoparse Desktop, which plans can use it, and where and how its tasks run.

## How is AI Assistant different from Octoparse Desktop?

With AI Assistant, you describe the data and Octoparse sets up the task. With Octoparse Desktop, you build the task yourself and control every step. See [AI Assistant, Desktop, or Open Platform?](https://www.octoparse.com/docs/en/ai-assistant/index.md#ai-assistant-desktop-or-open-platform)

## Which languages can I use?

Any language. Describe what you need in your own words.

## Do I need a paid plan?

Not to get started. You can build and run tasks on Free, including Cloud Agent runs on Octoparse Cloud, up to 100 rows per run and 2,000 rows a month. Upgrade when you need more rows, scheduled runs, or more saved tasks. Building beyond the free allowance for new accounts is paid from credits. See [Credits and plans](https://www.octoparse.com/docs/en/ai-assistant/credits-and-plans.md).

## Does every run use AI?

No. Browser Use and Cloud Agent use AI only while they build the task. Each run after that follows the same rules. See [How AI Assistant works](https://www.octoparse.com/docs/en/ai-assistant/how-it-works.md#how-it-picks-a-route).

## Can one chat collect data from several sites?

No. Each chat builds a task for one site or data source. Start a new chat for each site. See [One site per chat](https://www.octoparse.com/docs/en/ai-assistant/describe-your-data.md#one-site-per-chat).

## Which route works for sites that need a sign-in?

[Browser Use](https://www.octoparse.com/docs/en/ai-assistant/browser-use.md), because it runs in your own browser. Cloud Agent can't sign in to sites.

## Can I schedule a Browser Use task?

No. Browser Use tasks run in your own browser, so you run them yourself. For scheduled collection, use [Cloud Agent](https://www.octoparse.com/docs/en/ai-assistant/cloud-agent.md).

## Can I run AI Assistant tasks through the API or MCP?

Not Browser Use or Cloud Agent tasks. Run and manage them in AI Assistant and your task list. The [API](https://www.octoparse.com/docs/en/api-reference/index.md) and [MCP server](https://www.octoparse.com/docs/en/mcp/index.md) work with templates and tasks built in Octoparse Desktop.
