Rev is a platform that offers transcription, captioning, and subtitling services. The company combines artificial intelligence and human expertise to deliver accurate and efficient solutions for businesses, individuals, and content creators.
With Rev, users can easily convert audio and video files into written text, repurpose content, improve accessibility, and streamline workflows. The platform supports a wide range of industries, including legal, academic, and media production.
However, Rev severely lacks post-transcription features. While the transcription itself is mostly reliable, there’s just not much else the app offers for its $15/hour automated transcription price tag. If you’re curious about how this impacts real-life performance, we analyzed their set of features in detail in our Rev review.
Here are some notable aspects of Rev’s transcription platform.
Rev’s AI-powered transcription service delivers fast and decent results. The proprietary speech recognition engine has been trained on a vast dataset of human-transcribed audio, enabling it to achieve an impressive 95% accuracy rate under optimal conditions. However, the keyword here is ‘optimal’ conditions. If your audio file has heavy accents or a lot of background noise, Rev struggles to meet that accuracy percentage.
The automated transcription service supports over 30+ languages and can generate transcripts within minutes, making it an excellent choice for high-volume projects such as podcasts, interviews, and lectures. Users can easily upload their audio or video files and receive a transcript in various formats, including Word, PDF, and TXT.
For projects that require the highest level of accuracy, Rev offers human transcription services. The company maintains a global network of over 72,000 freelance transcriptionists who are carefully vetted and trained to deliver 99%+ accuracy.
Human transcription is particularly valuable for complex audio, such as recordings with multiple speakers, heavy accents, or technical jargon. Rev’s transcriptionists follow strict formatting guidelines and can handle a variety of audio quality levels. The average turnaround time for human transcription is approximately 16 hours.
However, it’s important to remember that their 99% accuracy with human transcription comes at a premium price of $120 per hour. If that is too much for you, there are other Rev alternatives that you should consider.
Rev provides both automated and human-generated captions and subtitles for video content. The platform’s captioning services help creators improve accessibility, reach a wider audience, and comply with regulations such as the Americans with Disabilities Act (ADA).
Rev’s caption editors are skilled in synchronizing text with audio-visual content and adhering to industry standards for readability and formatting. They can also describe non-speech elements, such as music and sound effects, to provide a more comprehensive viewing experience.
The platform supports a variety of caption and subtitle formats, including SRT, VTT, and SCC, making it easy to integrate with popular video hosting platforms like YouTube, Vimeo, and Wistia.
GoTranscript is a transcription and captioning service that combines human expertise with technology to deliver flexible solutions for a wide range of industries. The platform supports over 50 languages and offers various customization options to meet the specific needs of researchers, journalists, content creators, and businesses.
Here are some reasons why GoTranscript is a competent transcription platform.
GoTranscript’s human transcription service achieves an impressive 99.4% accuracy rate for standard audio and video files. The company maintains a global network of experienced transcriptionists who are well-versed in industry-specific terminology and can handle a variety of accents and audio quality levels.
Clients can customize their transcripts by choosing between clean verbatim (omitting filler words) or full verbatim (including all utterances) formatting. Additionally, users can opt for timestamping at regular intervals or speaker changes, making it easier to navigate and reference specific sections of the transcript.
GoTranscript offers flexible turnaround times, ranging from 6 hours for urgent requests to 5 days for more complex projects. This allows users to prioritize speed or cost-effectiveness based on their individual needs.
For challenging audio recordings with background noise or heavy accents, GoTranscript provides an optional secondary review process. While this service incurs an additional fee, it significantly reduces error rates and ensures the highest level of accuracy for critical projects.
GoTranscript’s AI-powered transcription service, known as Speech-to-Text AI, offers a fast and cost-effective solution for less critical projects. The AI technology can efficiently handle clear audio files and deliver transcripts in a matter of minutes.
However, GoTranscript recognizes the limitations of AI transcription and offers a unique proofreading API. Users can submit AI-generated transcripts for human review and correction, ensuring a higher level of accuracy. If the initial AI output fails to meet quality standards, GoTranscript refunds the fee to the user’s account, allowing them to reinvest in either revised AI processing or full human transcription.
This hybrid approach combines the speed and affordability of AI technology with the precision and reliability of human expertise, providing users with a flexible and cost-effective solution for their transcription needs.
GoTranscript offers professional subtitling and captioning services to help content creators improve accessibility, reach a wider audience, and comply with regulations. The company’s experienced captioners specialize in synchronizing text with audio-visual content and adhering to industry standards for readability and formatting.
Key features of GoTranscript’s subtitling and captioning services include:
GoTranscript offers two AI transcription pricing models—Pay-As-You-Go and Subscription—with differences in cost and features.
Sonix’s automated transcription engine is the foundation of the platform, supporting over 53 languages and dialects. The AI-powered system can handle diverse audio quality, including background noise and multiple speakers, delivering accurate transcripts in minutes.
Sonix’s automated transcription is not only fast but also highly accurate, achieving accuracy rates of up to 99%, thanks to its advanced machine learning models that are continually refined based on user feedback.
Rev’s automated transcription service leverages a proprietary speech recognition engine trained on over 6.2 million hours of human-transcribed audio data, achieving a 95% accuracy rate in optimal conditions.
The AI handles 38+ languages and generates transcripts within minutes, making it ideal for high-volume workflows such as podcast production or academic research. However, as we mentioned earlier, Rev’s accuracy is severely reliant on the audio quality. While tools like Sonix have sound processing systems in place to ensure that the ASR can accurately detect the spoken words, Rev does not have such software in place.
GoTranscript’s Speech-to-Text AI tools prioritize speed for less critical transcriptions. While the AI handles clear audio efficiently, the platform provides a unique proofreading API where users can submit AI-generated transcripts for human correction.
If the initial AI output falls below quality thresholds, GoTranscript refunds the fee to the user’s wallet, allowing them to reinvest in either revised AI processing or full human transcription.
Sonix makes team collaboration seamless with features like shared folders, real-time editing, and comment threads. Teams can assign role-based permissions to control access, while every change is tracked to maintain version accuracy. Whether reviewing transcripts, adding notes, or managing content workflows, Sonix ensures that everyone stays aligned, making it ideal for fast-paced, content-driven teams across any industry.
Rev facilitates collaboration through shared folders, real-time annotations, and role-based permissions. Administrators can assign roles (e.g., editor, viewer) to team members, audit activity logs, and manage billing centrally; a critical feature for legal teams handling sensitive materials or academic groups coordinating research.
GoTranscript supports team-based transcription with features that help streamline collaboration and organization. Each user gets a dedicated workspace to manage their own projects, while built-in commenting tools allow team members to leave notes directly on transcripts. Real-time updates keep everyone informed of progress, and automatic saving ensures that no work is lost, helping teams stay productive and on track.
Sonix integrates smoothly with tools like Zoom, Dropbox, Google Drive, Microsoft Teams, and Adobe Premiere Pro, making it easy to import, transcribe, and edit files without disrupting your workflow. These integrations help automate repetitive tasks, streamline media production, and support seamless collaboration, perfect for professionals who need transcription to fit directly into their existing toolset without added friction.
Rev integrates with over 20 productivity, multimedia, and conferencing tools. For instance, Zoom and Microsoft Teams recordings can be transcribed automatically, while Adobe Premiere Pro users import Rev-generated subtitles directly into video timelines.
GoTranscript’s cloud-native API supports large-scale integration through two primary endpoints: Automatic Transcription API and Forced Alignment API. However, GoTranscript does not offer integrations with any third party tools directly.
To help you make an informed decision, here’s a scoring table, based on a 5-point scale, that provides a comparative view of their features.
