Mouth shapes that match the phonemes.

Cheap talking-head apps use averaged mouth blends — the result reads as 'AI avatar.' Postcrest's pipeline aligns the mouth to the audio phoneme by phoneme, matching consonants and vowels. The result reads as a real recording.

  • Phoneme-level alignment
    Each phoneme gets its correct mouth shape across 30+ languages.
  • Natural expressions
    Blink, smile, head-tilt — auto-generated, not stiff.
  • Identity locked
    Eye shape, jawline and hair line stay yours through every frame.

  • Voice cloning
    30-second sample clones your voice for use in every talking-head video.

How Postcrest compares

Why creators move from Synthesia and HeyGen.

Avatar-only platforms force you to use their stock avatars and pay per minute of output. Postcrest brings your face and unlocks the rest of the AI video stack.

Synthesia
Avatar-only, enterprise-priced
Stock avatars only or custom avatars at enterprise-only pricing. Phoneme-accurate but locked behind seats.
With Postcrest
Use any photo as the source, phoneme-accurate lip-sync, voice cloning — at a fraction of Synthesia's cost.
HeyGen
Limited avatar library
Custom-avatar training requires uploading a 2-min video and waiting hours. Per-minute generation pricing.
With Postcrest
Use a single photo. Add voice cloning. Flat-rate subscription with no per-minute output cap.
Free lip-sync apps
Avatar-quality only
Averaged mouth shapes that read as 'AI avatar.' Limited languages, low resolution, watermarked.
With Postcrest
Broadcast-quality phoneme alignment, 30+ languages, up to 4K, watermark-free.
