# Unicaption vs Fireflies.ai for Interpreters: Which Fits?

> Fireflies.ai is a meeting assistant that typically joins calls as a participant to record, transcribe, and summarize them afterward, which suits teams that want searchable meeting notes. Unicaption is a live captioning and translation copilot for interpreters: it runs on your own device, joins nothing, shows captions with side-by-side translation in 60+ languages as people speak, never stores audio, and deletes transcripts when the session ends. Choose by job: notes afterward or live support during.

## What each tool is built to do

Fireflies.ai is a meeting assistant. As of this writing it is typically connected to your calendar, joins scheduled calls, records and transcribes them, and produces searchable transcripts and summaries your team can review later. Check its current site for exact features, languages, and plans.

Unicaption is a real-time captioning and translation copilot for interpreters and anyone who needs live captions. It listens through your microphone or your computer's system or tab audio, shows captions as people speak, and displays translation side by side in 60+ languages. Nothing joins the call.

## Why notetaker bots are hard for interpreters

- ⚠ **A bot is a visible participant.** Courts, clinics, and many corporate clients remove or forbid them.
- ⚠ **The product is the record.** Interpreting confidentiality usually means leaving no record. See [interpreter confidentiality and AI tools](/blog/interpreter-confidentiality-ai-tools.html).
- ⚠ **Summaries aren't what you need mid-assignment.** You need the name, number, or term the speaker just said.
- ⚠ **You may not control the meeting.** Adding a bot usually requires the host's permission.

## Where Fireflies is the better choice

- **Internal team meetings** where everyone consents to being recorded and wants searchable notes.
- **Sales and customer calls** where summaries and action items matter more than live text.
- **Archives.** If a durable, searchable record is the goal, a tool designed to keep one is right.

> If you're an interpreter who also runs your own business meetings, using a notetaker for those and a live copilot for assignments is a perfectly reasonable split.

## Frequently asked

**Is Fireflies.ai good for interpreters?**
Fireflies.ai is built to record and summarize meetings, which suits team notes but conflicts with the confidentiality norms of most interpreting work, since it keeps recordings and typically joins as a bot. Interpreters usually want live support with nothing retained. Unicaption runs on your own device, joins nothing, and deletes transcripts when the session ends.

**Can Unicaption replace Fireflies.ai?**
Only for a different job. Unicaption provides live captions and translation during a session and deliberately keeps nothing afterward. If you need a searchable archive of meetings and summaries, Fireflies or a similar notetaker is the better fit.

**What is the best alternative to a meeting bot for interpreters?**
A captioning tool that runs on your own device instead of joining the call. Unicaption captions microphone or system audio with side-by-side translation in 60+ languages, so no participant appears in the meeting and the host doesn't need to change a setting.
