What is TonePerfect?
Hi! I'm Nik, a solo founder, and I make TonePerfect.
You record a word or a sentence and get a score for every word and every sound, so you hear exactly which sound gives your accent away.
- 8 courses: English, Mandarin Chinese, Spanish, French, German, Russian, Japanese and Korean
- Mandarin: each syllable's tone is scored separately from its initial and final
- Japanese is scored on sounds only (pitch accent is not scored)
- Free browser accent check, no signup: https://toneperfect.app/accent-check
- Free tools: Mandarin tones test (https://toneperfect.app/mandarin-tones-test) and a pinyin chart with audio (https://toneperfect.app/pinyin-chart)
- Apps: iOS, Android and web (https://toneperfect.app/learn). Free tier with daily limits, Premium subscription.
For developers there is a pronunciation API (https://api.toneperfect.app): 10 languages, experimental, scripted speech, 50 free credits without a card.

Call Out Your ICP By Name In The H1 And Across Every Landing-Page Section
Pren credits getting the ICP right as the single biggest landing-page lever. Naming his ICP (Power AI users) not just in the H1 but across multiple sections kept the right visitor self-identifying as they scrolled — and lifted the page's conversion against the same organic and paid traffic that earlier landing pages couldn't convert.
$50 and I'll give you your money back if you write every day for 30 days so everyone who came in put $50 into a PayPal pot and I said I'll donate the rest whatever we end up
Launch with refundable accountability money
If you lack the credibility to charge for v1, use refundable accountability money instead of a real price. Collect $50 into a pot, refund anyone who completes the challenge, donate the rest. You get a real filter for serious participants without claiming to be a guru, and you validate demand with actual dollars on the table.
There's a play for whatever you're stuck on.
