I’ve tested quite a few tools recently for summarizing, organizing, and reviewing content, from class notes to podcasts. Here’s what stood out, starting with the one I’ve been using most:

1. getrecall.ai: It handles YouTube, PDFs, Spotify/Apple Podcasts, and web pages. Summarizes into bite-sized cards, lets you chat with your notes, and builds a self-organizing knowledge base. Been super helpful for studying and content review.

2. Mindgrasp: Good at summarizing lectures and answering questions from uploaded material. Feels geared toward students, especially for exams and dense PDFs.

3. Obsidian: Not AI-first, but ideal for linking concepts and building a knowledge graph. Works great with community plugins.

4. Evernote: Still decent for basic note organization and sync, but hasn’t really kept pace with newer AI-powered tools.

5. Notion: Flexible for team or solo use. Notion AI helps with summaries and generation, though it’s more assistant-style than research deep dive.

6. Eightify: If you want a quick hit of what a video’s about, it’s fast and reliable. But lacks deeper interaction with the content.

7. NotebookLM: Google’s experimental tool lets you upload docs and chat with them. Promising for research-heavy tasks, but still in beta.

8. NoteGPT: Handles both YouTube and PDFs with a nice UI. Helps with creating study notes fast, though less interactive than Recall.

Let me know what else is worth trying, especially anything that handles long-form stuff without breaking.
