Meetings are essential for collaboration, but they can also be time‑consuming and hard to document. AI meeting assistants promise to transcribe conversations, extract action items, and generate summaries automatically—freeing participants to focus on the discussion instead of note‑taking.

This comparison looks at three popular platforms: Otter.ai, Fireflies.ai, and Grain. We evaluate them on transcription accuracy, integration options, privacy controls, and overall usefulness for teams and solo operators.

How we compared these meeting assistants

We tested each tool across five criteria:

  • Transcription accuracy – especially with technical terms, accents, and overlapping speech
  • Integration depth – how well they connect to calendars, video platforms, and work‑chat apps
  • Privacy and data handling – where audio and transcripts are stored, and who can access them
  • Action‑item extraction – ability to identify decisions, tasks, and deadlines automatically
  • Pricing transparency – clear plans, fair usage limits, and predictable costs

Otter.ai: the established player

Otter.ai is one of the longest‑running AI meeting assistants. It offers real‑time transcription, speaker identification, and a clean, searchable archive of past meetings.

Strengths: High accuracy for clear audio, excellent search functionality, and a generous free plan (600 minutes per month). Its mobile app is polished and reliable.

Limitations: Integration with Zoom and Google Meet works well, but support for other platforms (Microsoft Teams, Webex) is less robust. The free plan limits export options.

Fireflies.ai: focus on workflow automation

Fireflies.ai positions itself as more than a transcription tool—it aims to automate meeting‑related workflows. It can push action items to project‑management tools, create CRM notes, and send follow‑up emails automatically.

Strengths: Deep integrations with Slack, Notion, Asana, and Salesforce. The AI is good at detecting action items and decisions. Unlimited transcription on paid plans.

Limitations: Accuracy can drop with poor audio quality. The free plan is very limited (800 minutes of storage, no integrations).

Grain: built for customer‑facing teams

Grain is designed specifically for sales, support, and customer‑success teams. It focuses on capturing “key moments” from customer conversations and making them easy to share and analyze.

Strengths: Excellent clipping and sharing features, strong privacy controls (GDPR compliant), and useful analytics on conversation trends. Integrates well with HubSpot and Salesforce.

Limitations: Less accurate for internal brainstorming or technical discussions. Pricing is higher for small teams.

Which meeting assistant is right for you?

The best choice depends on your primary use case:

  • Otter.ai – ideal for general‑purpose meeting transcription, especially if you want a reliable free tier and strong search.
  • Fireflies.ai – best for teams that want to automate follow‑ups and push action items directly into their project‑management tools.
  • Grain – strongest for customer‑facing teams (sales, support) that need to capture and share conversation highlights.

For most small teams and solo operators, we recommend starting with Otter.ai’s free plan to test whether automated transcription delivers enough value. If you need deeper workflow automation, consider upgrading to Fireflies.ai.

FAQs

Are these tools secure for confidential meetings?

All three offer enterprise‑grade security options, but you should review their data‑storage policies. Otter.ai and Grain are GDPR compliant; Fireflies.ai offers on‑premise deployment for highly sensitive environments.

Can they handle non‑English languages?

Otter.ai supports several languages (Spanish, French, German, etc.); Fireflies.ai and Grain are primarily English‑focused. Accuracy for non‑English languages varies.

How much time can these tools save?

Depending on meeting frequency, they can save 30–60 minutes per meeting by eliminating manual note‑taking and follow‑up summary writing.
