Otter.ai vs Fireflies.ai: 2026 comparison

Otter.ai and Fireflies.ai in brief

Otter.ai and Fireflies.ai both turn meetings into information you can revisit through transcripts, summaries and search. Otter.ai specifically highlights live transcription, speaker identification and questions about meeting notes. Fireflies.ai explicitly lists action detection, meeting recording and file imports. Both have free offerings, so initial access is not the main dividing line. Platform availability, export formats and published hosting information provide further ways to assess which service fits your workflow, while the records do not establish a difference in transcription accuracy or summary quality.

Entry price

The first paid plan, per month, gives the minimum cost of regular use; higher plans cost more. Otter.ai : $8.49 per month. Fireflies.ai : $10 per month. Edge: Otter.ai.

Public API

An API lets you connect the tool to your software, an automation tool or an AI agent. Otter.ai : yes. Fireflies.ai : yes. A tie on this point.

Data export

Being able to get your content back avoids lock-in the day you want to switch tools. Otter.ai : yes. Fireflies.ai : yes. A tie on this point.

Track record

A tool launched several years ago has a longer history: less risk of sudden shutdown, more user feedback. Otter.ai : launched in 2018. Fireflies.ai : not published. Cannot be decided: data missing on one side.

Recognition

Our analysis

Otter.ai focuses on making meeting content available for later consultation and questioning. Live transcription and speaker identification support the record of the discussion, while searching across meetings and asking questions about notes support retrieval afterward. Fireflies.ai also lists transcription, summaries and conversation search, with explicit attention to identifying actions to complete. Recording meetings and importing files provide additional documented ways to bring material into that process. These are useful distinctions in the described workflows. They do not establish whether one service captures speech more faithfully, produces more reliable summaries or identifies every relevant action in a meeting involving your team.

Both services use a freemium model and offer free access, but the supplied records do not describe the free plans’ limits. Otter.ai lists Pro at USD 8.49 per user per month with annual billing. Fireflies.ai lists Pro at USD 10 per user per month with annual billing, or USD 18 with monthly billing. Otter.ai therefore has the lower published entry price on the annual basis. That does not establish a lower cost for identical usage. Meeting allowances, storage volumes and other plan limits are not supplied, so the prices need to be read alongside information that remains unpublished in this comparison.

Otter.ai states that data is hosted in the United States. Fireflies.ai lists mixed hosting without explaining the locations or arrangement. Both products are closed source, and the records do not provide retention periods, content reuse rules or deletion conditions. Otter.ai documents TXT, DOCX, PDF, SRT and MP3 exports, depending on the plan. Fireflies.ai lists PDF, DOCX, SRT, CSV, JSON, MD, MP3 and MP4, with downloads available from Pro. These formats describe different possibilities for reusing outputs. They do not establish confidentiality safeguards or explain all the processing conditions that apply to meeting recordings and transcripts within either of the two services.

Otter.ai lists web, Windows, macOS, iOS, Android and API access. Fireflies.ai lists web, iOS, Android, an extension, an API and Teams. Your existing working environment can therefore be a practical filter before you assess the meeting outputs themselves. Otter.ai lists one interface language and no French interface; Fireflies.ai does not disclose interface languages. Neither statement establishes the transcription languages supported. The scores of 85 and 68 concern access and transparency. They do not measure speech recognition accuracy, summary reliability or performance in difficult conversations. The supplied records cannot determine which service would handle your own meeting conditions more successfully.

Depending on your situation

The right choice depends on use. For a few common situations, here are the criteria that matter and who wins (Otter.ai value / Fireflies.ai value).

Personal use on a tight budget

Here, Otter.ai has the edge: it wins 1 of the 3 criteria that matter in this situation, namely free tier (yes / yes), entry price ($8.49 per month / $10 per month), and interface languages (1 / not published).

Business use with client data

Neither stands out on the criteria for this situation (data hosting (United States / several regions), data export (yes / yes), and track record (launched in 2018 / not published)): decide with a trial.

Integration with your software

Neither stands out on the criteria for this situation (public api (yes / yes), open source (no / no), and platforms (web browser, Windows, macOS, iPhone and iPad, Android, and API / web browser, iPhone and iPad, Android, browser extension, API, and Microsoft Teams)): decide with a trial.

Which one to choose?

Choose Otter.ai if…

• you value entry price ($8.49 per month)
• you value recognition (cited in 3 lists)

Otter.ai fits when live transcription, speaker identification and questions about meeting notes are central to your needs. Listed Windows and macOS availability may also suit your working environment. Its annual Pro entry price is lower in these records. US hosting is explicitly stated, although the supplied information leaves retention rules and the exact allowances of each plan unresolved for your assessment.

Choose Fireflies.ai if…

Fireflies.ai does not lead on any measurable criterion; it is still relevant if you already use it or prefer it after a trial.

Fireflies.ai fits when action detection, meeting recording and file imports are priorities. Teams availability and an extension may suit the environment you already use. CSV, JSON, MD and MP4 add documented output options, with downloads starting at Pro. Mixed hosting still needs more detail if data location is a deciding requirement, and the listed features do not establish transcription quality.

Conclusion

Otter.ai aligns with live meeting capture and later questions about notes, at a lower published annual Pro entry price. Fireflies.ai explicitly covers actions, imports and additional export formats. Choose according to your platforms, the outputs you need and your requirements for data location. Access and transparency scores do not settle transcription accuracy. The available information also leaves plan allowances and several data handling conditions unresolved for both services.
