OpenAssistantGPT is an open-source SaaS platform for building AI chatbots and agents on top of the OpenAI API. Instead of stitching together APIs by hand, you point the platform at your website or upload documents, and it crawls and indexes the content so the assistant can answer questions grounded in your own material. The builder is entirely no-code, and the generated bot can be embedded on a site in a few clicks.
The platform leans on OpenAI's Assistants and Responses APIs, so you can power your bots with models such as GPT-4o and GPT-3.5 and benefit from improvements as OpenAI ships them. Beyond plain Q&A, it supports AI Agent Actions that call API endpoints with specific parameters, web search for fresh information, file attachments for analysis, and lead-capture forms that collect visitor contact details. For workplaces, SAML/SSO authentication can restrict a chatbot to employees only.
Because the project is open source, the code is available on GitHub (including a chatbot SDK for Next.js and Vercel deployment), and the team also runs a changelog documenting ongoing development. Pricing scales from a free tier for personal experiments up to paid plans for organizations running many bots, with enterprise options for compliance and scale.
Crawl your help docs and site so the chatbot answers common questions and reduces incoming support tickets.
Embed a RAG assistant that answers user questions about features, using your documentation as its knowledge source.
Use multi-bot plans and custom domains to deploy branded assistants for several clients from one dashboard.
Deploy a private, SSO-protected chatbot so employees can query internal documents and files safely.
