Gladia review
A developer-focused API for multilingual, real-time, and asynchronous transcription.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Gladia is an API infrastructure platform for companies and developers building voice products. It supports asynchronous transcription for pre-recorded audio and real-time streaming transcription, with applications across virtual meetings, contact centers, media workflows, sales tools, and other audio-processing products. The platform includes automatic language detection, code-switching, speaker diarization, word-level timestamps, subtitle export, custom vocabulary, PII redaction, sentiment analysis, entity detection, summarization, translation, and audio-to-LLM processing. It runs through an API and supports Windows, macOS, and Linux development environments.
Pricing is usage-based rather than seat-based. Starter provides pay-as-you-go asynchronous transcription at $0.61 per hour, 100+ supported languages, speaker diarization, real-time transcription, and 50€ in one-time free credits. Growth lists asynchronous transcription as low as $0.20 per hour and real-time transcription as low as $0.25 per hour, with flexible concurrency limits, custom volume discounts, and automatic model-training opt-out. Growth requires an upfront usage commitment, making it more appropriate for teams with predictable demand than for occasional experiments. Enterprise adds custom pricing, custom models and fine-tuning, unlimited concurrent requests, zero data retention, custom hosting, and custom SLAs.
The main strength is breadth for developers building multilingual voice workflows: Gladia combines transcription modes, language handling, speaker labels, timestamps, text and subtitle exports, and audio intelligence in one API. Integrations with Pipecat, LiveKit, Vapi, Recall, Meeting BaaS, Attendee, Twilio, VideoSDK, Composio, Zapier, Make, and n8n extend its ecosystem fit. Choose Gladia when multilingual coverage, real-time processing, or developer-controlled audio features matter. Teams wanting a free plan, monthly seat pricing, or a simple end-user transcription app should consider a different type of product.
