Which is better: VOMO or Sonnet? In this blog, I personally test both products and share practical recommendations.

To save you time, we start with a quick and straightforward review to help you decide. A detailed comparison follows later in the article.

Let's begin!

Generally speaking, VOMO and Sonnet each shine in audio transcription and speech to text tasks, but they serve different needs.

VOMO excels at transforming recordings—whether they’re voice memos, Zoom calls, or YouTube transcripts—into smart AI meeting notes and summaries using advanced AI models.

Sonnet, on the other hand, focuses on real-time dictation during live meetings, capturing context-rich, customizable notes directly into your workflow.

VOMO builds its audio-to-text capabilities on the Whisper engine and other advanced AI models（Microsoft、Deepgram）, yielding accurate results even from recordings and voice memos. It handles multiple speakers, different file formats, and can even process video to text content like YouTube clips.

Sonnet processes live audio with minimal latency, focusing on transcription accuracy during the conversation—especially when clarity matters most.

Summarization & AI Meeting Notes – Which Tool Captures the Essentials?

VOMO excels at delivering clean AI meeting notes: decisions, action items, and summaries are neatly organized and ready to share. It’s superb for processing uploaded files or video to text conversion.

Sonnet takes a different approach by offering meeting notes that embed pre-call context, participant background, and CRM-ready summaries—ideal for teams that rely on structured conversational history and follow-ups.

VOMO works anywhere via web and IOS app—drag in voice memos, uploads, or even paste a YouTube Transcript link. It handles transcription and summarization in one place.

Sonnet installs as a lightweight sofware, starting transcription automatically during calls. It pushes outcomes to Slack, Notion, or CRM tools and maintains shared conversation histories.
