How to Use AI to Take Notes (and Actually Remember What Matters)

The short answer: AI can transcribe your meetings in real time, summarise documents and articles, and turn messy raw notes into clean, organised output. The best tool depends on the task — Otter.ai for live meetings, ChatGPT or Claude for everything else.

Here’s a common scenario: you sit through a one-hour meeting, take a page of scrawled notes, and by the time you get back to your desk you’ve already forgotten which three things you were supposed to follow up on. Or you spend twenty minutes highlighting a long report, only to read those highlights later and have no idea why you marked half of them.

AI doesn’t solve every note-taking problem. But it solves several of the most annoying ones — and once you’ve tried it, going back feels like choosing to do something the hard way.

The two main ways to use AI for notes

1. Transcription and meeting notes — AI listens to (or reads) spoken conversation and turns it into text, then summarises it.

2. Summarisation and organisation — AI takes raw notes, long documents, or pasted text and condenses it into something more useful.

Both are genuinely valuable. Most people end up using both regularly.

For meetings: Otter.ai

Otter.ai is the tool designed specifically for this. It can join a meeting, transcribe everything said in real time, identify who said what, and automatically generate a summary with key points and action items when the meeting ends.

You don’t write anything. You don’t even need to pay attention to note-taking — you can focus on the conversation itself, knowing the transcript is there when you need it.

How to get started with Otter.ai:

Create a free account at otter.ai
Connect it to your Google Calendar or Outlook — it will automatically detect meetings and offer to join
When a meeting starts, Otter joins as a participant and begins transcribing
After the meeting ends, you get a summary, a full transcript, and key action items in your inbox

The free plan gives you 300 minutes of transcription per month — enough for most people to get a feel for it. The paid plan (around $17/month) removes limits and adds features like more AI summaries per month and custom vocabulary for industry-specific terms.

If you have a recording instead of a live meeting: You can upload an audio or video file to Otter and it’ll transcribe it the same way.

For documents, articles, and long text: ChatGPT or Claude

If you’re reading a long report, research paper, set of meeting notes, or any chunk of text you want condensed, paste it into ChatGPT or Claude and ask for what you need.

Some useful prompts to try:

Straight summary:

“Summarise this in five bullet points, focusing on the most important information.”

Action items only:

“Read through this meeting transcript and pull out every action item, who is responsible, and any deadlines mentioned.”

Condensed version:

“This is a 20-page report. Give me the key findings and recommendations in plain English, in about 300 words.”

Structured notes:

“Turn these rough notes into clean, organised bullet points grouped by topic.”

Fill in the gaps:

“I took these notes during a lecture but some parts are unclear. Can you help me flesh them out based on the context?”

Claude is particularly good at handling long documents — it can process much larger chunks of text without losing track of the beginning by the time it reaches the end. If you’re working with lengthy material, Claude tends to perform better than ChatGPT on this specific task.

For lectures and classes

If you’re a student, the combination of recording + AI transcription is a genuine game-changer.

Record your lecture (most smartphones have a built-in voice recorder). After class, either upload the recording to Otter.ai or use a free transcription tool, then paste the transcript into ChatGPT or Claude with a prompt like:

“This is a transcript from a university lecture on [topic]. Summarise the key concepts, definitions, and any examples given. Format it as study notes.”

What you get back is better than most notes taken in real time — organised, complete, and in language you can actually understand when you come back to it later.

For things you read online

If you come across a long article and want the gist without reading the whole thing, paste the text into Claude or ChatGPT and ask:

“What is the main argument of this article and what evidence does it use to support it?”

Or if you want to save it for later:

“Turn this article into brief reference notes I can come back to — key points, main takeaways, and anything worth remembering.”

Some browsers have AI reading assistants built in now. But pasting into ChatGPT or Claude works just as well and gives you more control over the output format.

A simple setup for most people

If you want a starting system without overthinking it:

Meetings: Set up Otter.ai, connect your calendar, let it run automatically
Documents and articles: Paste into Claude with a clear summarisation prompt
Rough notes from your own head: Type them into ChatGPT and ask it to clean them up and organise them

You don’t have to use all three. Pick the one that addresses the note-taking friction you actually feel most, try it for a week, and add more from there.
