AI note-taking apps can make it much easier to capture, organize, summarize, and find information on a Windows 11 PC. Instead of manually writing everything during meetings, lectures, research sessions, or brainstorming, many AI-powered note-taking tools can automatically organize information and turn long conversations into useful summaries.
The best app depends on what you need. Some tools are designed mainly for meetings, while others work better for personal notes, research, project management, or organizing large amounts of information. Features such as AI summaries, transcription, search, automatic organization, integrations, and collaboration can make a major difference.
Here are some of the best AI note-taking apps you can use with Windows 11.
1. Microsoft OneNote
Microsoft OneNote is one of the most familiar note-taking applications for Windows users. It provides a flexible digital notebook where you can create pages, sections, lists, drawings, screenshots, and other types of content.
OneNote becomes more useful when combined with Microsoft’s AI features and services. It is a good option for users who already work with Microsoft 365.
Key Features

Another advantage is its integration with the Windows ecosystem. If you already use Microsoft services, OneNote can fit naturally into your existing workflow.
2. Notion
Notion combines note-taking, databases, project management, documentation, and collaboration in one application.
Its AI capabilities can help transform ordinary notes into more useful information. For example, you can use AI to summarize content, improve writing, extract important points, and work with information stored inside your workspace.
Key Features
- AI-assisted writing
- Note organization
- Databases
- Project management
- Templates
- Collaborative workspaces
- Document creation
- Search
- Task management
- Team collaboration
Why Choose Notion?
Notion is a strong choice if you want more than a basic note-taking application.
You can create a workspace for a project and store meeting notes, tasks, documentation, research, and related information together.
For example, a software development project could have separate pages for:
- Meeting notes
- Development tasks
- Documentation
- Product ideas
- Research
- Project deadlines
This makes Notion useful for individuals as well as teams.
3. Microsoft Copilot
Microsoft Copilot can be useful when your notes are already part of the Microsoft ecosystem.

- Summarization
- Information organization
- Integration with Microsoft products
- Content generation
- Question answering
- Productivity assistance
Why Choose Copilot?
Copilot is worth considering if you regularly use Microsoft Word, OneNote, Teams, Outlook, or other Microsoft services.
For example, after collecting information from a meeting or project, AI assistance can help turn that information into a concise summary or action list.
This can reduce the amount of time spent manually reviewing long notes.
However, the exact Copilot features available to you depend on your Microsoft account, subscription, application, and organizational configuration.
4. Otter.ai
Otter.ai is focused heavily on meeting transcription and AI-generated notes.
It can be particularly useful for people who attend frequent online meetings and want a searchable record of conversations.
Instead of trying to write down everything while participating in a meeting, you can use a transcription-focused tool to capture the conversation and review the generated notes afterward.
Key Features
- Meeting transcription
- AI-generated summaries
- Speaker identification
- Searchable transcripts
- Meeting organization
- Action-item extraction
- Support for online meetings
Why Choose Otter.ai?
Otter.ai is a good choice for meetings, interviews, discussions, and other situations where spoken information needs to be converted into text.
It can save time because you do not have to manually type every important statement.
After a meeting, you can review the transcript and focus on the summary and important points instead of going through the entire conversation.
Before using an AI transcription service for a meeting, make sure participants and your organization permit recording and transcription where required.
5. Evernote
Evernote is a long-established note-taking platform that has added AI-powered features to improve the way users organize and retrieve information.

- Project information
Instead of keeping everything in separate applications, Evernote provides a central location for your notes.
Its search and organization features can also make it easier to find older information.
6. Google Keep and Gemini
Google Keep is a simple note-taking service, while Google’s AI ecosystem can provide additional assistance when working with information.

You can quickly create a note without setting up a complicated workspace. This makes it useful for shopping lists, ideas, reminders, quick research notes, and short pieces of information.
Users who already rely heavily on Google services may also find it convenient to keep their notes within the same ecosystem.
For larger projects, however, a more advanced application such as Notion or OneNote may provide better organization.
7. Mem
Mem takes a different approach to note-taking by focusing heavily on AI-assisted organization and retrieval.
Instead of requiring users to manually build a complicated folder structure, AI can help connect information and make older notes easier to discover.
Key Features
- AI-assisted note organization
- Search
- Automatic connections between information
- Personal knowledge management
- Writing assistance
- Note discovery
- Flexible organization
Why Choose Mem?
Mem can be useful if you frequently collect large amounts of information but do not want to spend significant time organizing every note.
For example, you could capture ideas, research notes, meeting information, and observations over time and then use AI-assisted search to locate relevant information later.
This approach can be especially helpful for people who prefer writing first and organizing later.
8. NotebookLM
NotebookLM is designed around working with information and source material rather than simply storing ordinary notes.

It can also help reduce the time required to manually review large documents.
How to Choose the Best AI Note-Taking App
