Its live transcription feature allows you to generate text transcripts as you speak, which is ideal for note-taking and real-time collaboration.

OtterPilot can also automatically capture images of slides shared during virtual meetings, making it easier for professionals to search for and recall important slides along with the transcript.

It uses AI to write real-time meeting notes and share them with everyone.

2. Integration With Other Tools

Additionally, with the Otter AI Chat, you can create summaries, follow-up emails, or even social media posts based on meeting content, saving time and effort on post-meeting tasks.

4. AI Channels

Channels are designated locations to store and organize transcripts and meeting notes from all team members who share the Channel.

So, team members can comment, highlight, and discuss specific sections within the transcripts, facilitating asynchronous collaboration and idea exchange.

Also, each Channel has its own dedicated Otter AI Chat, allowing you to ask questions, summarize insights, and generate content based on all conversations within that Channel.

New team members can quickly become familiar with a channel by accessing past conversations, understanding context, and identifying ongoing initiatives.

Rev Overview

Rev is an online platform offering transcription, captioning, and translation services. It guarantees high-quality, accurate, fast turnarounds for audio and video files.

It supports over 58 languages and has an accuracy of up to 86%. While that isn’t as high as Sonix’s 99%, their main selling point is the human transcription service. Rev’s team of transcription experts can produce transcriptions with 99% accuracy, but at a significantly higher cost and longer turn around time.

Other key features of Rev include the following.

1. Human Transcription

While Rev does provide AI-powered transcription, human transcription is at the forefront of their attention.

Rev’s human transcription surpasses the quality of their AI services and is capable of producing content with accuracies up to 99%.

However, if you’re interested in Rev solely for their AI transcription, it’s important to note that their increased interest in the human side of the business has led to less frequent upgrades to their AI capabilities.

• Streaming API: Designed for real-time transcription needs, such as live captioning or voice-driven applications.

Rev’s API simplifies the integration process by allowing developers to easily incorporate the API into their applications using Rev’s user-friendly SDKs (Software Development Kits) in multiple programming languages.

Pricing

Rev has two different websites for two different business models. The first is Rev.AI, which is the front page for their API platform.
