What we know about Lemonfox.ai

Lemonfox.ai is a speech-to-text apis platform: cheapest hosted Whisper large-v3 API for batch transcription. This profile tracks every Lemonfox.ai fact we have verified, each linked to a primary source and dated.

On pricing, Lemonfox.ai starts at $5 per month for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes.

On capabilities, Lemonfox.ai covers language auto-detection, word-level timestamps, custom vocabulary / keyterm boosting, speech translation, and gdpr / eu data residency, and does not offer entity detection, sentiment analysis, and summarization endpoint. Each of those is verified against Lemonfox.ai's own docs or dashboard, not marketing copy.
