Question: Can you recommend a platform that allows me to create a custom AI assistant using data from various sources like websites, PDFs, and Notion?

If you want to build a custom AI assistant that can consume data from multiple sources like websites, PDFs and Notion, Modelit could be a good fit. It can aggregate information from multiple sources to help you better. Modelit lets you connect information across different sources, coauthor documents and converse with your AI assistant. It also integrates with data sources like Google Drive, Notion and JIRA, and lets you customize templates, workflows and tone of voice.

Another contender is OmniMind, a no-code service for building custom AI chatbots. It can be trained with a variety of data sources like websites, PDFs and YouTube videos. OmniMind features include document-backed responses, voice interaction and a customizable look. The service can be used for support and e-commerce, and can help you cut time with quick, accurate responses.

For a general-purpose no-code AI app development foundation, check out MindStudio. It lets people build their own custom AI tools and automations without writing any programming code. MindStudio lets you pick and compare models, connect to multiple data sources and use an API. It's priced on a tiered system and you only pay for the AI models you use, so it's potentially economical.

Last, Whismer is another no-code AI chatbot creation service that lets you upload documents and web pages to train AI models. It's geared for teams and professionals who want to build custom AI tools for specific jobs, with a rapidly created AI knowledge base and one-click sharing of AI projects.
