I’ve spent the last few weeks testing free AI note-taking apps for PKM. Two names kept coming up: beanly and tidenote. They both promise to capture ideas and summarize long content in seconds, but they take very different routes. If you’re trying to decide which fits your workflow, here’s what I found.
How tidenote handles PKM – the AI-first approach
Tidenote leans hard on AI from the start. You can drop in a lecture recording, a meeting transcript, or even a messy page of research notes, and it’ll spit out a clean summary. I used it for a few weeks, mostly for class lectures and meeting recaps. The summaries are readable, not robotic, but they do miss the occasional nuance – especially when a speaker used heavy irony or gave a long example that was actually part of the argument. You have to check the original.
One thing that surprised me: tidenote has a Notes section that lets you write alongside the AI output. I also kept a quick daily Journal in the app, and it auto-tagged entries based on content. That’s handy for PKM when you’re trying to link ideas across weeks. But the AI’s tagging isn’t perfect – it once lumped “book notes” and “grocery list” under the same theme. Not a dealbreaker, but worth knowing.
Beanly vs. tidenote – different tradeoffs
Beanly is another free AI note-taking app I tested alongside tidenote. Beanly feels more structured: it forces you to set a “type” (meeting, class, journal) before you start, and then it builds a template around that. That’s great if you want consistency, but I found it slower for quick capture. Tidenote lets you just talk or paste and get a summary immediately. For raw speed, tidenote wins.
But beanly has a better linking system. It supports Anchor Text – you can highlight a phrase in one note and link it to another note or even a web page. That made cross-referencing ideas in my PKM much easier. Tidenote has a backlink feature, but it’s buried and not as intuitive. I missed that when I tried to build a knowledge graph.
On the free tier, both have limitations. Tidenote gives you a monthly AI credit cap – around 200 minutes of audio or 50 pages of text. That’s fine for light users, but I hit the cap a few times while preparing for exams. Beanly’s free plan is more generous on credits but limits export formats. Tradeoff either way.
The “小片刻” factor and real-world use
A friend of mine who studies Mandarin uses tidenote to capture short audio snippets – he calls them 小片刻 (little moments) – and the app transcribes and summarizes them in seconds. That worked surprisingly well. The AI handled code-switching between English and Chinese decently, though it stumbled on proper names. For a free app in 2026, the multilingual support is better than I expected.
Meanwhile, I tried beanly’s meeting mode for a weekly team standup. It captured action items cleanly, but the speaker labeling was off – it couldn’t distinguish two people with similar voices. Tidenote’s speaker diarization was slightly better, but still not perfect.
Which free AI note-taking app should you use for PKM?
If your PKM needs are mostly about capturing and summarizing – lectures, meetings, quick research reads – tidenote is the more straightforward choice. The AI summary quality is strong, and the notebook-style layout keeps things simple. But if you rely on linking ideas, building a knowledge graph, or need structured templates, beanly might serve you better despite the slower start.
For a best free AI note taking app in 2026, I’d recommend tidenote for most casual users. It’s fast, clean, and does what it promises without a heavy setup. Just keep an eye on the credit cap. For power users who treat PKM like a second brain, beanly’s linking and templates make it the smarter pick.
Either way, both are worth installing. But don’t expect either to replace manual reading entirely – the AI still misses context. Use the summaries as a starting point, not a final answer.
