The clearest difference is provider choice. ChatGPT is OpenAI's storefront: you get their models, their rules, and their availability. Scholarly is a multi-provider workspace: the same chat can run on GPT 5.6, Claude Sonnet 5, Gemini 3.1 Pro, Grok 4.6, or Mistral Large 3, and you can change models mid-conversation when one fits the job better. Teams in regulated or restricted environments also care that different providers draw different content lines; with five labs available, one provider's policy is never the end of the conversation.
The second difference is what happens after the chat. ChatGPT's output is a thread. Scholarly's output is an artifact: a narrated video lecture built from your onboarding manual, a three-speaker podcast from a research paper, a graded practice exam from lecture notes, or a cited report from a folder of sources. Everything stays grounded in the library you uploaded, with citations back to the page.
On price: ChatGPT Free now includes unlimited basic chat and ChatGPT Business is $25 per seat per month, so if all you need is a general assistant, ChatGPT is a fine default. Scholarly Premium ($30/mo or $144/yr) and Premium Teams ($35/seat/mo) are for people whose work lives in documents: unlimited multi-provider chat plus weekly creation credits that turn those documents into training and study material.
