⚡ 簡単な評価:
- 価格: Mem AI has a free plan and Mem Pro at $12/month. Our pricing record for Microsoft OneNote lists contact-based pricing.
- 最適な用途: Mem AI suits people who want AI to handle organization. OneNote suits people who already live inside Microsoft apps.
- 主な違い： Mem AI drops folders and lets AI group similar notes. OneNote keeps notebooks, sections, and pages.
- 私たちのおすすめ： Microsoft OneNote for most users, because it is free across Windows, Mac, iOS, and アンドロイド.
The app with fewer AI features wins this one.
Mem AI has the smarter brain of the two.
It reads your notes and links related ideas on its own.
Microsoft OneNote skips most of that and stays free.
That single difference decides which note taking app fits you.

Mem AIとは何ですか？
Mem AIは aiノート app that organizes your notes for you.
Kevin Moody and Dennis Xu built it in 2019 to handle information better.
There is no folder system here, so manual organization mostly disappears.
Instead, the AI groups similar content and surfaces it when you need it.
That turns all your notes into a personal knowledge base you can 質問.
Many people treat Mem as a second brain rather than a filing cabinet.
Here is a short walkthrough of how the app works day to day.
メムAI
Mem AI links your notes without tags or folders. Ask a question in plain words and it finds the answer.
Mem AI の価格設定
Mem keeps its pricing plans short and easy to read.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| メム | 無料 | Testing the basic features first |
| メモリプロ | 月額12ドル | Solo writers who want mem’s ai features |
| メンバーチーム | カスタム価格設定 | チームコラボレーションと知識の共有 |
価格は2026年7月に確定しました。
無料トライアル: The free version acts as the trial, so you can create notes before paying.
返金保証: Mem does not publish a refund window. Start on the free plan instead.
📌 注記： The smart features that make Mem interesting sit behind Mem Pro. The free tier is a taste, not the full app.
⚠️ 警告： Mem Teams has no public price. You will need a sales conversation before you can budget for a team rollout.
Mem AIの主な利点
Here is what makes Mem worth a look:
- Automatic grouping: Mem analyses notes semantically and connects relevant information. You skip tags and folders.
- スマート検索: Ask a question the way you would ask a person. G2 reviews describe it as closer to Google than to a filter box.
- Related notes on tap: Mem surfaces similar notes and documents next to whatever you are reading.
- テンプレート: Build custom templates for ミーティング notes or research. Repeat work stays consistent.
- 輸入品: Pull in Google Calendar events and Slack messages so different pieces of context live together.
- Summaries: Mem can summarise a page or pull one detail, working like a personal アシスタント.
- より速い想起： Mem reports up to a 60% cut in time spent hunting for important information.
This video shows those benefits in a live workspace.

1. AI Features and Smart Assistance
メムAI: The AI is the product, not an add-on. It reads every note, links relevant information, and builds a knowledge base you can query. Mem describes 2.0 as a “parallel mind” that helps execute tasks, while Mem X connects notes and integrates with email and calendar.
マイクロソフト OneNote: OneNote offers Copilot for summarising pages and pulling out key points. The ai helps once you ask, but it will not reorganise anything on its own. Your structure stays yours.
2. Writing, Drawing, and Handwritten Notes
メムAI: Mem leans on content generation. It learns your writing style and drafts in your 声. There are no drawing tools, so a stylus is out.
マイクロソフト OneNote: You can handwrite notes, sketch diagrams, and annotate a clipped page. Optical character recognition then makes that ink searchable. Students and whiteboard thinkers get real value here.
3. Templates and Structure
メムAI: You can create templates for different note types, which keeps repeat work consistent. Beyond that, structure is loose by design. The app groups similar notes for you.
マイクロソフト OneNote: Pre-built and custom templates cover meeting notes, lesson plans, and project management pages. You can also run multiple notebooks side by side. The customization options run deep.
4. ユーザーインターフェースと学習曲線
メムAI: The user interface is minimal on purpose. There is almost nothing to learn, so you start taking notes in minutes.
マイクロソフト OneNote: The learning curve is the most common complaint. New users face ribbons, panes, and options everywhere. Power arrives later, once the layout clicks.
⚠️ 警告： OneNote functionality varies depending on the device. The windows version carries the most features, and the mobile app is a 簡略化された version of OneNote.
5. Integrations and Other Apps
メムAI: Mem syncs your calendar and imports from tools like Google Calendar or Slack. Pasting from Google Docs works fine, so different pieces of a project land in one place.
マイクロソフト OneNote: The pull here is Microsoft Office. Moving files between Microsoft Word, Excel, and PowerPoint takes seconds. If your team already uses those microsoft office applications, this matters more than any AI trick.
6. Knowledge Base and Second Brain
メムAI: Mem turns passive notes into データ you can question for patterns or recurring feedback. That is the second brain ピッチ, and it is the strongest argument for the app.
マイクロソフト OneNote: OneNote stores knowledge but does not connect it. Links between pages are manual. You get an archive, not a thinking partner.
7. Smart Search and Finding Notes
メムAI: Smart search understands plain questions, so you find notes quickly even when you forget the exact wording. Mem also surfaces related notes beside whatever you are reading.
マイクロソフト OneNote: The search features are keyword-based, though OCR technology extends them into images and ink. Tags and custom tags do the rest of the sorting work.
8. Summaries and Meeting Notes
メムAI: Ask Mem to summarise a page or pull one detail and it answers like a personal assistant. Handy after a long call when you need the decisions, not the transcript.
マイクロソフト OneNote: You can record audio during a lecture and let voice transcription handle the rest. Copilot then summarises the page and highlights key points.
9. Real Time Collaboration and Sharing
メムAI: Team collaboration sits on the Mem Teams plan, which uses custom pricing. Solo users get the AI organizer but little in the way of shared editing.
マイクロソフト OneNote: Co-authoring is free. Multiple users edit one file at once, and you decide between edit or view-only access when sharing notes with other onenote users.
10. 価格設定とコスト
Let’s put the pricing plans side by side.
| プラン | メムAI | マイクロソフト OneNote |
|---|---|---|
| 無料 | Mem: Free | 正確な価格についてはお問い合わせください |
| 個人 | Mem Pro: $12/month | 正確な価格についてはお問い合わせください |
| チーム | Mem Teams: Custom pricing | 正確な価格についてはお問い合わせください |
メムAI: $12 a month buys オートメーション you would otherwise do by hand. If AI organisation saves you an hour a week, the maths works. If it does not, the free version feels thin.
マイクロソフト OneNote: Our record lists contact pricing, while Microsoft documents a free app backed by 5GB of cloud storage. Either way, nobody is paying $12 a month for basic features here.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Zero budget | マイクロソフト OneNote | Free on every platform |
| AI to organize for you | メムAI | 手作業による整理は不要です |
| 手書きのメモ | マイクロソフト OneNote | Stylus and ink search |
| に ブレインストーミング ideas fast | メムAI | Links related thoughts on its own |
| Free team collaboration | マイクロソフト OneNote | Co-authoring costs nothing |
| Reliable mobile apps | マイクロソフト OneNote | Fewer crash reports |
💰 あなたの予算
OneNote asks for nothing up front, so there is no renewal date to worry about. Mem asks $12 a month for the parts that make it special.
🔌 あなたの技術スタック
If your day runs through Microsoft apps, OneNote is the obvious answer. If you live in Google Docs and Slack, Mem slots in with less friction.
📝 あなたの文章スタイル
Typists who capture messy thoughts will like how Mem organizes notes effortlessly. Anyone who sketches or annotates needs OneNote instead.
🎓 あなたの経験レベル
Mem is easier on day one because there is less to configure. OneNote rewards patience, and its depth only makes sense after a week of use.
🆓 無料トライアルとデモ
Run the same week of notes through both apps before you decide. Import one real project, not a test page, so the comparison is helpful.
🛟 サポートオプション
OneNote support runs through Microsoft support pages and a large user forum. Mem leans on documentation and email, which is thinner but usually quicker.

私たちのレビューで取り上げられなかったこと
This comparison focused on solo users and small teams. For example, we did not test the android version at scale, enterprise rollouts, or heavy word processing workflows. Data-residency rules and long-term sync behaviour also sit outside our scope. If you manage fifty seats or work in a regulated industry, your priorities will differ from ours.

🏆 WINNER: MICROSOFT ONENOTE
Microsoft OneNote wins 4 out of 7 categories.
最適な用途: students, Microsoft Office teams, handwritten note takers, and anyone who wants a free app that syncs everywhere
These two apps answer different questions. Mem AI asks what your notes mean. Microsoft OneNote asks where your notes should live.
Mem is the better thinking tool. Its ai features do real work, and the search alone can save you an afternoon of digging.
OneNote wins because it costs nothing, runs everywhere, and never leaves you stuck without an internet connection. For most people that combination beats a smarter brain behind a paywall.
