Gladia vs Superwhisper

Gladia provides audio infrastructure through an API for recording, transcribing, and enriching audio. It offers asynchronous and real-time transcription, including live streaming, with Starter supporting 100+ languages and automatic language detection and switching. Listed audio tools include speaker diarization, sentiment analysis, PII redaction, entity detection, and audio-to-LLM processing. Developers can use Python or Node.js SDKs, WebSocket streaming, or REST uploads; named integrations include Pipecat, LiveKit, Twilio, Retell, Zapier, Make, and n8n. Transcripts can include speaker labels and timestamps, and SRT and VTT are listed export formats. Starter is listed at free and includes 50€ in one-time credits that do not expire. Flexible pay-as-you-go Starter rates are $0.61 a month for asynchronous transcription and $0.75 a month for real-time transcription. Hourly call and total audio limits vary by tier. Gladia also offers GladiaFlow, a desktop voice dictation app for Mac and Windows; its code is available under the MIT license.

Superwhisper turns speech into formatted text for use across applications. Its Super Mode reads the screen and adjusts dictated text to the current app, for example treating email as a message or coding prompts technically. It supports more than 100 languages, automatic language detection, and translation between languages. On-device speech models process audio locally, work without internet, and keep audio off the device's outbound path. With cloud models, audio and text pass through the Superwhisper proxy to the provider; the product says they are not retained for training. It works wherever text can be entered and names Slack, Cursor, and Notion, with coding plugins for Claude Code, OpenCode, Codex, and Pi. A CLI can search and export transcripts, report recording statistics, and start a local MCP server. Free includes voice-to-text, meeting recording and transcription, and email support. Pro costs $8.49 per month or $84.99 per year and adds audio and video transcription, cloud and local models, custom API keys, and priority support. Pro features can be tried for 3,000 words before free-tier features remain available.
