Almost every notes app is free — the honest question is where free stops. Free usually means one of three things: an ad-supported free tier of a paid product, a genuinely free app that sells a Pro upgrade, or open-source software with no paywall at all. Knowing which kind you're picking matters more than the download itself, because the wall you'll eventually hit is different in each. We make one of the apps below, so we'll disclose that and keep the list honest.
The shortlist
| If you want | Start with | Where free ends |
|---|---|---|
| The Apple default, already installed | Apple Notes | Free for good; capped by iCloud storage, and it's Apple-only |
| Cross-platform, sync everywhere | Google Keep | Free, but light on structure — no folders, no formatting depth |
| A local-first power tool | Obsidian | Free for personal use; Sync and Publish are paid add-ons |
| Fast personal capture on iPhone, private | Clair Mind | Free forever to capture, organise, and search; AI is a paid Pro tier |
| One workspace for docs and projects | Notion | Generous free plan; teams and heavier use hit member/limit walls |
Where "free" actually ends
The trade-off is never that there's no cost — it's what you pay with.
- Storage. Apple Notes and Evernote's free tiers are limited by how much you sync, not by features. Fine until you hit the ceiling.
- Sync and devices. Obsidian is free on every platform, but keeping notes in step across them is a paid service (or a DIY setup). Free-but-manual is still a real cost.
- Feature gates. Evernote's free plan has grown notably tighter over the years — a reminder that a free tier can shrink after you've committed years of notes to it.
- AI. The newest wall. Most apps now let you try AI free, then charge for it — ours included. Clair Mind is free forever for capturing, organising, and searching; the AI that answers across your notes is a paid Pro tier after a short trial. That's the honest line, and you should hold every "free AI notes" app to it.
Free doesn't mean no lock-in
The most expensive part of a free app is the one nobody prices: getting your notes out. An app can be free and still trap you, if export is clumsy or lossy. Before you pour a year of thinking into anything free, confirm it exports to plain text or Markdown you'll own regardless. Open-source and files-based tools like Obsidian pass this by design; some polished free apps quietly don't.
How to choose a free app you won't regret
- Match it to the moment, not the feature list. For fast personal capture you want the app that opens instantly; for a shared second brain you want structure and search. Different jobs, sometimes different tools.
- Find the wall before you hit it. Read where the free tier stops — storage, sync, or AI — and decide whether that wall is one you'll ever reach.
- Pick the method too. A free app plus a real habit beats a paid app you never open. The Cornell method for lectures or a light PKM workflow does more for you than any upgrade.
The honest bottom line
If you're on Apple and want zero decisions, Apple Notes is free and fine. If you want local files you'll own forever, Obsidian is free where it counts. If you want fast, private capture on iPhone with AI you can try before you buy, Clair Mind is free for the core and asks for money only when you want the AI. Whatever you pick, the free part is real — just read the wall it ends at first.
