Why people look for a Letterly alternative
Letterly is good at one job: turning a quick spoken thought into a clean email, post or note. Two things push people elsewhere. Each note is limited to 90 minutes, which rules out long meetings and lectures. And its App Store listing shows $99.99 for 12 months of Pro, twice the price of Spiik Pro.
If you mostly want rewrites of short thoughts, AudioPen is the closest match. If your recordings run longer, or you want to study from them or ask them questions, Spiik is the better fit.
