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.

So I have Tanna.ai now which is great, but a problem is that sometimes I need to take notes from PDFs that have a lot of pictures in them and want AI to fill in the blanks. I was able to do this with ChatGPT4o and it did a great job, but I have to split the PDFs into 10 - 15 page chunks which is inconvenient.

I'm wondering if there's any other apps out there at do this and will let me put in full PDFs. I'm willing to pay don't don't want to pay anymore than $10 USD a month. WIlling to do a yearly plan as well.
