What we know about Gladia

Gladia sits in the speech-to-text apis category, where it is eU-based real-time and batch STT API built on the Solaria models. We keep this Gladia profile grounded in primary sources, each fact dated to when we last confirmed it.

Gladia does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Gladia quote, it is the fastest way for us to close that gap.

On capabilities, Gladia covers language auto-detection, word-level timestamps, custom vocabulary / keyterm boosting, entity detection, sentiment analysis, and summarization endpoint. Each of those is verified against Gladia's own docs or dashboard, not marketing copy.

For compliance, with Gladia: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Gladia before you commit, since these change plan by plan.

Among the 43 speech-to-text tools in our matrix, Gladia leads with the 4th-widest language coverage; the fact sheet below has the raw numbers behind that placement.

In total we track 28 verified facts for Gladia today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the Gladia fact sheet below.
