Description: Answers to common questions.

Start with the problem you observed. If you need individual help, [contact us](/en/contact#contact-form) and describe what you tried to do and where it failed.

**Can I use Aihio for free?**

Access and a suitable subscription are arranged during onboarding. Check
current options on [pricing](/en/pricing) or [request a
demo](/en/contact#contact-form). Do not assume that separate registration is
open.

**Where is my data stored?**

Check the personal data Aihio processes and how it is handled in the
[privacy policy](/en/legal/privacy-policy). Your agent's purpose and the
data you provide need a separate assessment. Do not add secrets or
unnecessary personal information to knowledge sources.

**How big can the knowledge base be?**

Check the selected workspace's usage and limit on the billing
**Subscription** tab. Current options are on [pricing](/en/pricing). Remove
duplicated and unnecessary content before expanding the knowledge base.

**Does Aihio support languages other than Finnish and English?**

Reply language and chat-interface language are different settings. Check the
available choices and fallback behaviour in the [language
guide](/en/help/ai-agent/languages). Test the languages your customers need
before launch.

**Why does the agent not use the information I just added?**

Saving a source does not publish the change. Check its content and status,
select **Update knowledge base** and wait for a successful update. Test
again. The [data sources guide](/en/help/ai-agent/knowledge) explains the
checks.

**Why is the chat widget missing from my website?**

Check the installation code, agent status and allowed website domain. Try
the published page in a private browser window. Follow the [publishing
troubleshooting
guide](/en/help/ai-agent/publish#if-the-conversation-does-not-appear).

## When contacting support

For data-access or deletion requests, see [data handling and deletion requests](/en/help/account/settings#data-handling-and-deletion-requests). Ordinary documentation feedback is not the channel for handling a privacy request.

Include the workspace and agent, time of the problem, browser and visible error message. Describe the expected and actual results separately. Remove personal information, API keys and other secrets from screenshots before sending them.
