What is Gladia?
Gladia delivers speech-to-text and audio intelligence APIs tailored for developers who need accurate, low-latency transcription inside their products. It combines asynchronous batch transcription with real-time streaming, multilingual support, and a growing layer of AI add-ons such as summarization, sentiment analysis, and entity extraction.
Gladia positions itself as “audio AI infrastructure” rather than just another STT endpoint, emphasizing universal language coverage, strong telephony performance, and a single API that spans async, real-time, and higher-level audio intelligence. The combination of precise multilingual transcription, low latency, and serious compliance, wrapped in a developer-friendly package, makes it an appealing building block for voice-first products.
Gladia offers a strong mix of accuracy, latency, language coverage, and compliance for teams building voice-enabled products. For developers who want to offload the hard problems of multilingual, real-time transcription while still having access to richer audio intelligence features, it presents a very compelling API-first option that scales from side projects to enterprise deployments.

How Gladia fits into your stack
Browser
Gladia provides a browser-based playground where teams can upload audio, start live sessions, and evaluate transcription models before integrating them.
Automation and APIs
The core product sits in an application backend through REST and WebSocket APIs, SDKs, callbacks, webhooks, and integrations with Zapier, Make, n8n, Pipecat, LiveKit, Twilio, and other voice infrastructure.
Desktop / IDE
GladiaFlow is a desktop dictation client that streams microphone audio to Gladia and pastes cleaned transcripts into the focused application, including editors, browsers, chat tools, and terminals.
Docs and writing
Gladia's transcription and audio-intelligence outputs support transcripts, summaries, translations, action items, entities, sentiment, and subtitle files for downstream documentation and content workflows.
Pros
- +High multilingual accuracy: Strong performance across European languages and many rarer tongues helps global products avoid “English-only” limitations.
- +Real-time ready for production: Sub-300 ms latency and stable behavior under load suit live agents, call centers, and interactive assistants.
- +All features included by default: Diarization, language detection, and other core capabilities are bundled rather than sold as nickel-and-dime add-ons.
- +Serious compliance story: Certifications plus options for zero data retention and hosting controls appeal to finance, healthcare, and other regulated sectors.
Cons
- −API-focused, not end-user software: Teams without in-house developers will still need another tool or custom app on top of the API.
- −Usage-based pricing can climb: High-volume media or analytics workloads must watch hourly costs and may need negotiated deals to keep budgets predictable.
- −Feature depth still evolving: While the core STT is mature, some audio intelligence add-ons may require evaluation in niche domains before large-scale rollout.
Limitations & when to consider alternatives
Known limitations
- No direct collaborator accounts. Gladia does not currently support adding collaborators directly to an account; teams must use a shared email approach.
- Audio and file-size limits. Standard API requests allow up to 135 minutes of audio and 1 GB per file. Larger limits require Enterprise.
- Credit exhaustion pauses API access. When the prepaid wallet reaches zero, API access pauses until credits are added or the plan is upgraded.
- Concurrency varies by plan. Starter lists 30 real-time and 25 asynchronous concurrent requests; Enterprise offers unlimited concurrency.
- No native mobile, browser, or desktop product is documented. Gladia is documented primarily as API-based audio infrastructure accessed through REST, WebSocket, SDKs, and integrations.
Look elsewhere when
- You need native team workspaces with named collaborators and roles.
- You need a native mobile, browser-extension, or desktop application.
- You need image understanding or vision input.
