What to look for in a transcript summarizer

Before we examine the results in further detail, let’s explore the metrics used for comparison.

Category

Transcript summarizers can either be generic or purpose-built to solve a specific problem. The type of summarizer you choose will impact the way in which the summary is generated. For example, some AI summarization models are built and trained on conversational data, like a virtual meeting, while others may be trained on static text inputs instead. 

Some summarizers also let you modify how the summary is displayed: a paragraph, bullet points, length, short, keywords, etc. Others tailor their output based on the industry the tool was built for, such as sales, virtual meetings, call coaching, or education. 

Accuracy

The accuracy of the AI transcript summarizer will be directly dependent on (a) the accuracy of the transcript used to generate the summary and (b) the accuracy of the AI summarization model used. Make sure to test each provider you are considering with audio/video files that match your intended use case to obtain the most useful results. 

Additional features available

Is transcript summarization the only feature you need or are there additional audio or conversation intelligence features you will need as well? Each of the providers discussed here vary greatly in their product offering, so make sure to choose the feature set that best matches your needs. 

Pricing

Some platforms contain their transcript summarizer within a bigger package or offering while others offer it as a one-off tool. The size of the platform and the size of the feature package will greatly impact the price, so take time to determine exactly what you need before deciding on a provider. Some providers also offer a free tier based on volume usage. 

Platform compatibility 

Finally, make sure to check platform compatibility prior to committing to a provider. For example, some platforms require you to supply pre-transcribed audio/video files while others will perform the transcription and summarization near-simultaneously. Other platforms seamlessly integrate into virtual meeting platforms like Zoom or Teams to generate the summary automatically. 

Ultimately, your specific use case will be the biggest factor in determining the best AI transcript summarizer for you, so let’s examine each of these tools more thoroughly.
