Gregator vs Perplexity
Pick Perplexity when you want a quick, cited answer to a question, or when you need to search and analyse your own files. Pick Gregator when you want to actually learn a topic: it researches the open web and gives you a saved, multi-chapter course with footnoted sources, quizzes, and a tutor that knows the course.
What Perplexity does well
Perplexity is an answer engine built around citations. Its pricing page says citations appear in every answer, including on the Free plan, so you can open the pages behind a claim straight away. For a factual question, a definition, or the latest news on a subject, that is hard to beat for speed.
The paid plans add depth. Perplexity's help center describes Pro as including more citations per answer, a Research mode for in-depth reports, uploads of PDFs, CSVs, audio, video, and images for analysis, a choice of advanced models, and tools to create files and simple web apps. Projects, which replaced Spaces in July 2026, keep shared files, instructions, and memory together for ongoing work.
If your question depends on your own material, such as a contract, a dataset, or lecture slides, Perplexity can work with it. Gregator cannot.
How Gregator works differently
Gregator starts from a topic, not a question. It plans a curriculum of 1 to 12 chapters sized to the topic, each with an objective and its own set of search queries. Research runs across seven search providers, including arXiv and Wikipedia. Up to 18 sources per chapter are extracted, with no more than 4 from one domain, and each chapter is written from its 7 most relevant sources under a domain and perspective diversity cap.
Every source is classified by type (peer-reviewed, institutional, journalism, community) and given an evidence-quality score with positive and negative signals. You see the result as a trust overview for the course, plus source and peer-reviewed counts on each chapter. Individual source scores are not shown.
Each chapter uses inline footnote citations placed after the claims they support, and ends with a Sources list. A course-level review checks for redundancy, difficulty spikes, coherence gaps, and one-sided sourcing on contested topics, and revises the chapters it flags.
Then the learning part: up to five multiple-choice questions per chapter with an explanation for each option, plus a final course quiz. Answers are graded on the server, and a wrong answer links back to the relevant section. Greg, the chat tutor, reads your chapters, can search the course and the web, and can offer a deep dive that adds a new chapter. Progress is tracked per chapter, and Gregator recommends what to learn next.
