Best App to Resurface Old Notes (Honest Comparison)
Old notes are useless if you never see them again. Five ways to bring them back, from random notes to daily review, and which app fits which habit.
By Silvia
Most of us are good at writing notes and bad at reading them again. You save a thought, close the app, and that note sits there for years. It was useful once. Now it is just storage. Here's how to resurface old notes, and which app does it best.
Notes only pay off when they come back: when you see an old idea next to a new one, or remember something right before you need it. So the real question is not "which app takes the best notes?" It is "which app gives my notes back to me?"
Four ways an app can bring notes back
Before comparing apps, it helps to know what kind of resurfacing you want.
- Random. The app shows you any old note. Simple, sometimes surprising, often not relevant.
- Scheduled. The app brings notes back on a rhythm, like a daily set or spaced repetition.
- Related. When you open or write a note, the app shows older notes about the same idea.
- On demand. You ask a question and the app answers from your notes.
Most tools do one or two of these. Here are five options and what they actually do.
1. Obsidian: Random note
Obsidian has a core plugin called Random note. It opens a random note in your vault, so you can revisit older notes and connect them to newer ones. The community has also built plugins for spaced repetition of notes and flashcards.
Good for: people who already live in Obsidian and like to tinker.
Where it stops: random is random. Scheduled review means choosing and setting up a community plugin yourself.
2. Readwise: Daily Review
Readwise brings back your highlights from Kindle, Apple Books, Instapaper and more, in a daily review in the app and by email. It uses spaced repetition, and you can tune how often each book or source type appears.
Good for: heavy readers whose best material is highlights.
Where it stops: the center is other people's sentences. You can attach notes to highlights, but your own standalone thinking is not the main thing it brings back.
3. Anki and other flashcard apps
Anki is a flashcard program that helps you spend more time on hard material and less on what you already know. It runs on desktop, with apps for iOS and Android.
Good for: facts you must remember exactly, like vocabulary or exam material.
Where it stops: you have to turn notes into cards by hand. It is a study tool, not a place where your notes live.
4. Mem: ask your notes, and Heads Up
Mem Chat lets you ask questions about your notes in plain language. By default it searches your whole workspace, and it can also create and edit notes. Heads Up shows related notes in the sidebar while you write, with no setup.
Good for: finding something when you already know what you are looking for.
Where it stops: Heads Up shows related notes while you write, but there is no daily set that brings old notes back on a schedule.
5. Linko: Daily review, related notes and Ask Linko
Linko is a notes app built around one idea: connect everything you learn and bring it back when it matters. It covers three of the four kinds of resurfacing.
Scheduled: Daily review gives you one set of your own notes each day. Linko turns a note into a question, you try to recall it, then you see your note. You can lean toward recent or older notes, and pick which tags and topics to include.
Related: every note shows related notes and resources, including ones from books, articles and videos you saved. See Find an idea you half remember.
On demand: Ask Linko answers from your notes and shows the notes it used.
Linko also adds tags and topics on its own, so notes are findable without you building a system first. (Why that matters: Where did all my notes go?) It works on the web, iOS and Android, with a web extension for saving pages. And if you use Claude or ChatGPT, Linko MCP lets them search your notes and cite them. See Linko's latest update for the full list.
Good for: people who write their own notes about what they read, watch and think, and want those notes to come back without extra setup.
Where it stops: it is not a flashcard drill for exact recall. If you need to memorize 2,000 words for an exam, use a flashcard app.
Quick picker
- A surprise from your vault now and then → Obsidian Random note
- Your best book and article highlights back daily → Readwise Daily Review
- Exact recall of facts → Anki
- Answers when you ask → Mem, or Ask Linko in Linko
- Related notes while you write → Mem Heads Up, or Linko
- Your own notes back every day, plus related notes, without setup → Linko
A habit that works with any app
The tool matters less than the loop. Whatever you pick, try this for two weeks:
- Write one line in your own words after anything worth remembering. Not a copy. What it means to you.
- Spend five minutes a day with whatever your app brings back.
- When an old note is still useful, add one sentence about where it applies now. That is how notes grow instead of pile up.
If your app makes step 2 automatic, you are far more likely to keep going.
FAQ
What is the easiest way to resurface old notes?
Use an app that brings notes back on its own every day. A daily set takes a few minutes and doesn't depend on you remembering to look.
Is spaced repetition good for notes, or only flashcards?
It works for both, but notes are not flashcards. Seeing a note again, and thinking about where it applies now, is often more useful than drilling it.
Can AI help me find old notes?
Yes. Tools like Ask Linko answer from your notes and show which notes they used, so you can check the answer and open the original.
Does Linko work with notes from books, articles and videos?
Yes. Save the resource, write about it, and Linko connects your notes across sources.
Do I need to organize my notes first?
Not in Linko. It adds tags and topics automatically, and you can change them anytime.
