Is AudioToTextAI's API a drop-in replacement for AssemblyAI?

AudioToTextAI offers a v1 (synchronous) and v2 (async + webhooks) REST API. Endpoints follow standard conventions — POST a file or URL, get back JSON with utterances, segments, and word-level timestamps. AssemblyAI's payload shape is different in detail but the migration is mostly a one-file adapter. Our diarization, summary, and translation fields are returned in the same response, not behind separate billable endpoints.

How does AudioToTextAI's accuracy compare to AssemblyAI?

AudioToTextAI picks the best output from multiple modern ASR models (Whisper Large V3, faster-whisper, SenseVoice, Deepgram Nova-3 when selected). AssemblyAI runs a single proprietary stack. On benchmark audio sets we publish under /models/, AudioToTextAI matches or beats AssemblyAI on English, multilingual, and noisy-audio slices. For your specific audio, free trial credits let you A/B both engines yourself.

What happens to my audio after AudioToTextAI processes it?

Audio files are encrypted in transit (TLS 1.3) and at rest (AES-256), processed on dedicated GPU infrastructure (not multi-tenant cloud ML services), and deleted on a configurable retention timer. We do not train models on customer audio. Compare AssemblyAI's retention and training-use policies in their privacy terms — they vary by tier.

Does AudioToTextAI cover the same languages as AssemblyAI?

AudioToTextAI supports 99+ languages including all major European, Asian, and Indic languages, plus several lower-resource African and Pacific languages. AssemblyAI's language list is typically narrower; check their docs for your specific language. We charge the same per-minute rate regardless of language — no rare-language surcharge.

Can I export AudioToTextAI transcripts in the same formats as AssemblyAI?

Yes — and more. AudioToTextAI exports to TXT, SRT, VTT (both subtitle formats), JSON (with word-level timestamps), DOCX (editable), and PDF (print-ready). Each is generated from the same canonical transcript so timestamps, speaker labels, and edits stay consistent across formats.

Privacy and Security
