FAQ

FAQ

Common questions about deploying and using the AI agent.

To deploy the AI agent you need a site (any HTML, WordPress, or CMS), a production webhook URL, and credentials for SerpAPI, Supabase, Google Calendar, Sheets, and SMTP. The setup is designed to be web-friendly and requires only basic configuration values: the webhook endpoint, branding options, and embedding code. Once connected, the widget loads on page load and starts capturing leads before chat. The memory and RAG context are stored in Supabase, which enables more accurate replies over time. You can customize the embed snippet to match your branding and positioning.

Yes. The widget uses a universal embed snippet that works on custom HTML sites and popular CMS platforms like WordPress. You simply paste the snippet into your page head or footer and configure branding, webhook, and colors. The agent then loads automatically on every page where the snippet is present. Ongoing updates to the embed script are hosted in your own repository, so branding and behavior stay in sync. If you switch domains, you can reconfigure the webhook without changing the site code.

Data security depends on how you configure Supabase, SerpAPI keys, and SMTP credentials. Memory stored in Supabase is isolated per session and can be restricted with access controls. You should implement standard privacy practices and consent collection for visitors. The architecture does not transmit sensitive information to third parties beyond configured integrations. You can review data retention settings in your Supabase and SMTP configurations.

Yes. The embed supports branding options such as logo, name, welcome text, and response time messaging. You can adjust colors, position, and typography to match your site. You can also customize response prompts and the tone of the AI agent to reflect your brand voice. Branding changes propagate through the widget without modifying the core workflow.

Leads are captured with name and email and stored in your connected tools (Google Sheets, Google Calendar) for easy retrieval. The session transcripts and key metadata are logged, enabling efficient follow-up and reporting. Access to data is controlled by your platform’s permissions and the integrations you enable. You can export data from Sheets or query it from Calendar as needed. Real-time updates ensure your team sees fresh information on every new chat.

If SerpAPI returns outdated or low-confidence results, the agent relies on its memory and other available context to avoid incorrect information. You can configure the freshness window for retrieved data and implement fallback sources when necessary. The system also logs the source and confidence level of fetched data for auditing. Regular updates to the knowledge base and prompts help keep the agent accurate. You can also manually update critical data via the admin interface.

Yes. The architecture is designed to be modular: you can connect additional data sources, CRMs, or messaging channels through n8n. New integrations share a common interface and memory model so context is preserved. You should plan your data mapping and access controls when adding tools. The UI and embed can be extended to accommodate extra capabilities without breaking existing flows.
