Transcription for Legal Work: What Actually Matters

Both Otter.ai and Fireflies.ai produce transcripts from meetings and calls. For legal professionals, the relevant questions are accuracy on legal terminology, speaker identification, integration with video platforms, and whether the transcript is exportable in a usable format.

Neither tool was purpose-built for law. Both have been widely adopted by legal professionals because they are affordable, easy to set up, and substantially better than manual note-taking. The differences are real but not dramatic.

Accuracy and Legal Terminology

General transcription accuracy for both tools is strong in standard English. Legal terminology — Latin phrases, case citation formats, procedural terms — sometimes produces errors in both platforms. Neither tool has a legal-specific language model.

Accuracy drops on calls with heavy accents, poor audio quality, or multiple speakers talking over each other. For formal client meetings with clear audio, both tools perform well. For a client call on a noisy street or a conference line with echo, expect more errors. In both cases, always review the transcript before relying on it for anything consequential.

Real-Time vs Searchable Archive

Otter.ai's real-time transcription experience is strong. The transcript appears word by word as the conversation happens, and you can highlight passages and add notes during the meeting. For attorneys who want to engage in a call while capturing everything, this live experience is genuinely useful.

Fireflies.ai focuses more on the post-meeting archive. Its search across all recorded meetings is fast and accurate. You can search for a term — a client name, a contract provision, a date — and pull up every meeting where it was discussed. For legal teams accumulating months of client meeting records, that searchability is valuable.

Speaker Diarization and Team Features

Both tools offer speaker diarization — identifying who said what in a multi-speaker recording. Neither is perfect, especially on calls where participants talk over each other or join late. Fireflies.ai has a bot called Fred that joins meetings automatically and labels speakers by their meeting profile names, which tends to produce more accurate attribution on structured calls.

Otter.ai and Fireflies.ai both offer team-level sharing, though Fireflies has more developed CRM integrations — connecting meeting records to Salesforce or HubSpot records. For law firms, this is less relevant than for sales teams, but it matters if you track client development activities.

Free tiers are available from both. Given that pricing is nearly identical, the practical advice is to test both on your most common meeting type — client calls, team check-ins, or depositions — and pick the one whose output you trust more.
