What is CustomGPT?
CustomGPT is an AI tool by CustomGPT.ai that builds RAG chatbots and agents from your company content for support teams, internal knowledge and website help. You train agents on sites, PDFs, videos, Notion, HubSpot or SharePoint and they answer with citations to the sources they used.
What is CustomGPT used for?
It lets you launch assistants that know your documentation without coding an embeddings pipeline. The no-code builder sets persona, tone and guardrails; the anti-hallucination engine favors answers grounded in your official data. It supports 90+ languages, model selection and white-label options for customer-facing projects.
How does it connect data and integrate?
It includes connectors for sitemaps, YouTube, Google Drive, Confluence, Shopify, Zendesk, Slack and Zapier, with auto-sync across sources. It exposes a RAG API and SDK to embed the agent in your product, and states SOC2 Type 2 and GDPR alignment. Enterprise adds private deployment and SSO for larger organizations.
CustomGPT pros and cons
Pros: source citations, RAG API, many connectors and a focus on cutting invented answers over your document base. Cons: agent and monthly query quotas vary by tier, white-label and advanced model controls are not on every tier, and it does not replace a full helpdesk because it focuses on search and conversation over your content.
- Support teams that want a cited bot on the knowledge base.
- Companies that need internal search across wikis and drives.
- SaaS products that embed a documented assistant via API.
- Associations and education teams with large content libraries.
