Universal credit system for multi-vendor TTS. One currency, every voice.
Pricing Strategy — Key Decisions
1
Universal Credits — 1 credit = 1 Standard character. Premium voices use 1.5 credits/char, Ultra uses 2.5 credits/char.
2
Volume Discounts — Pack price per credit drops 40% from smallest to largest pack, rewarding commitment.
3
Vendor-Agnostic — Customers pick voices by quality tier, not vendor name. You can swap vendors without repricing.
4
Arabic Premium — NuN's linguist-tuned Arabic voices are positioned as Premium, justifying the markup over commodity TTS.
5
Credit Rollover — Unused credits roll over for 90 days, reducing churn and purchase hesitation.
6
Competitive Moat — Pricing undercuts ElevenLabs API ($0.12–0.30/1K chars) while offering multi-voice flexibility.
