NotebookLM vs Otter.ai: Picking the Best AI Meeting Note Taker

The weekly sales call kicks off in a Brisbane co-working space, the calendar packed with back-to-back Zooms, and somewhere between the second flat white and the third Teams check-in, the realisation hits: nobody on the call is actually listening. They are typing. That scene has become the everyday reality for thousands of small business owners across Australia, which is exactly the problem AI meeting note takers were built to solve.

Two names come up more than any others when Australian founders, agency leads and accountants shop around: Google's NotebookLM and Otter.ai. Both promise to listen, transcribe, summarise and distribute action items without anyone having to scribble furiously during a client call. They take very different routes to that destination, though, and the right pick depends on the kind of meetings you actually run from your Sydney office or Melbourne coworking desk.

What each tool actually does

NotebookLM arrived from Google in 2023 and is positioned less as a live meeting recorder and more as a research companion that happens to handle audio. You feed it source material, such as PDFs, Google Docs, slide decks or uploaded audio files, and it builds a notebook around that content. From there, you can ask it to summarise the materials, pull out themes, or generate audio-style "deep dive" overviews in a podcast format. It is a tool for thinking with a body of information, rather than for capturing a Zoom call in real time.

Otter.ai, by contrast, is built squarely around the live meeting. It joins a Zoom, Microsoft Teams, Google Meet or Webex call as a virtual participant, transcribes the conversation as it happens, tags different speakers and produces a clean summary once the call ends. It also offers an OtterPilot that can automatically slide into recurring meetings, and a chatbot called Otter Chat that lets you interrogate the transcript after the fact. For Australians who live inside Zoom and Teams all day, that live-assistant framing tends to feel more familiar.

Transcription quality and language handling

Accuracy is where most buyers in Australia make their decision, because local accents and industry jargon can quietly destroy an otherwise clever tool. Otter.ai supports English with regional variants, and its accuracy on Australian English has improved noticeably over the past year. It handles common terms like "arvo", "brekkie", "servo" and place names reasonably well once the speaker dictionary is tuned, though heavy Scottish, Irish or strong multicultural accents occasionally trip it up. In head-to-head testing on recorded calls from Perth and Adelaide offices, Otter typically lands around 85 to 90 percent word accuracy on clear audio.

NotebookLM does not do live transcription in the same way. Instead, you upload an audio file after the meeting and let it process the recording. Because it leans heavily on Google's speech models, the accuracy on uploaded Australian English files is very strong, particularly when the recording quality is good. The catch is that there is no live speaker labelling or real-time output. If you want instant meeting minutes in front of a client, Otter wins. If you want to interrogate a long recording after a board meeting in your Hobart office, NotebookLM's source-grounded approach gives you deeper, citation-backed answers.

Integrations and workflow fit

The way a tool slots into the rest of your stack matters just as much as raw accuracy. Otter.ai plugs directly into the most-used meeting platforms and then pushes notes into Slack, Notion, HubSpot, Salesforce and a long list of CRM tools. It also exports to common formats and sends summaries by email the moment a call ends. For an Australian sales team that runs everything through HubSpot and Slack, that ecosystem feel is a quiet productivity win. It pairs nicely with surrounding tools, and teams that already rely on best payroll services for small businesses for HR often pick Otter to keep the back-office conversation aligned with the front-office one.

NotebookLM integrates tightly with the Google ecosystem, which is a real advantage for any Australian team already using Google Workspace. You can pull documents straight from Drive, sync notebooks across team members, and export summaries back into Docs or Gmail. Its third-party integrations are more limited than Otter's, and there is no calendar or meeting platform hookup in the same league. For a sole trader in Canberra running their business out of Gmail and Drive, however, that tight Google fit can be exactly the right shape.

Pricing in Australian dollars

Budget is always part of the conversation, particularly for small businesses managing tight cashflow between Sydney and regional Queensland. Otter.ai runs on a freemium model with a generous free tier that covers around 300 minutes of transcription per month, capped at 30 minutes per conversation. The Pro plan, billed annually, works out to roughly AUD $220 per user per year once currency conversion is factored in, and unlocks unlimited recordings, advanced search and speaker identification. The Business tier adds admin controls and heavier CRM integrations.

NotebookLM is currently free to use with a Google account, although Google has hinted at paid features and higher usage limits in the future. For a price-sensitive founder in Adelaide who is still deciding whether AI note taking is essential, that zero-dollar entry point is hard to beat. The trade-off is that the feature set is narrower and the roadmap less predictable, so it pays to factor in a possible future migration if Google tightens access.

Privacy, data storage and local compliance

Australian buyers tend to ask sharper privacy questions than most, partly because of the local regulatory environment and partly because of high-profile breaches reported in the press. Both products handle audio recordings and transcripts, which means the rules around the Privacy Act 1988 and the Notifiable Data Breaches scheme can apply if you are recording conversations with customers, patients or staff.

Otter.ai stores transcripts on US infrastructure and relies on standard contractual safeguards. Its settings let you delete recordings automatically after a chosen window, and its enterprise plans offer single sign-on, encryption at rest and customer-managed keys. For teams handling sensitive information, the Australian Signals Directorate's Essential Eight framework is worth checking against any vendor's documentation before signing up. NotebookLM sits inside Google Workspace, which means it inherits Google's existing data handling, regional storage options and enterprise controls, including the ability to keep data within Australian regions for Workspace customers. That can simplify compliance for legal, healthcare and education users in Melbourne and Brisbane who already operate inside Google's ecosystem.

When to choose each tool

The honest answer is that these tools serve slightly different jobs, and the best one for your team depends on what your meetings actually look like. Otter.ai is the stronger choice for anyone who lives in live Zoom or Teams calls, wants real-time transcription, and needs clean notes and action items landing in Slack or a CRM within minutes. It is also the safer bet for sales, account management and customer success teams that need conversation history linked to a contact record.

NotebookLM is the stronger choice for anyone who treats meetings as raw material to think with, such as consultants turning client interviews into strategy documents, researchers synthesising long recordings, or educators building study notes from lectures. Even a creative retailer like Coenen Schoenmode, working across international teams, could lean on NotebookLM to turn supplier calls into structured briefs without paying for a live meeting seat. Pick the tool that matches the moment, not just the marketing page, and the hours saved per week tend to follow.
