Fireflies.ai

Freemium

Fireflies.ai joins video calls as a bot, or records through a Chrome extension, desktop or mobile app, then turns the conversation into a searchable transcript with a summary, action items and speaker labels. It works with Zoom, Google Meet, Microsoft Teams and other platforms, transcribes in more than 100 languages and accepts uploaded audio or video files. AskFred answers questions across past meetings, and search spans the archive by keyword, topic or participant. Conversations can be pushed to CRM and project tools. Free accounts include limited AI summaries and 400 minutes of team storage.

AssemblyAI

Freemium

AssemblyAI sells speech models through an API rather than a consumer app. Developers send a file or live stream and get transcripts with timestamps, speaker labels, formatting and confidence scores; other endpoints summarize calls, detect topics and sentiment, or redact personal data. Its Universal speech models cover 99 languages, and a newer text-to-speech model targets voice agents. Billing runs per hour of audio processed, starting at roughly $0.15 per hour for pre-recorded transcription. The free tier covers about 185 hours of pre-recorded audio and 333 hours of streaming before charges begin.

Descript

Freemium

Descript treats video and audio as editable text. It transcribes your recording, and deleting a sentence in the transcript removes that section from the timeline, which makes trimming interviews and tutorials faster than scrubbing waveforms. Studio Sound cleans up room noise and uneven levels, filler words can be stripped in one pass, and the AI co-editor drafts cuts, scripts and clips on request. It also records screen and camera, generates voice clones, and dubs finished videos into other languages on paid plans. Business tiers add avatars and brand controls. The free plan includes an hour of media a month with watermarked exports.
