What we know about Deepgram
Deepgram is a speech-to-text apis platform: developer-first realtime STT API for voice agents and transcription at scale. This profile tracks every Deepgram fact we have verified, each linked to a primary source and dated.
Deepgram 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 Deepgram quote, it is the fastest way for us to close that gap.
On capabilities, Deepgram covers language auto-detection, word-level timestamps, custom vocabulary / keyterm boosting, entity detection, sentiment analysis, and summarization endpoint. Each of those is verified against Deepgram's own docs or dashboard, not marketing copy.
For compliance, with Deepgram: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Deepgram before you commit, since these change plan by plan.
Placed against the 43 speech-to-text tools we track, Deepgram's strongest showing is the 26th-widest language coverage - a spread worth weighing against your own priorities.
In total we track 29 verified facts for Deepgram 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 Deepgram fact sheet below.

Want it done for you?
Deepgram gets you a transcript; the bot that joins the call, labels speakers, and writes the summary is still your build. If that is more pipeline than you want to own, AI meeting notetakers do the whole job end to end: Otter.ai, Fireflies.ai, Fathom, or the full notetaker comparison.
