AudioPen vs Letterly: Features, Pricing and User Reviews 2026

AudioPen Prime uses one-time payments instead of monthly subscriptions, so you pay once and keep access for a set period.

• 3 Month Pass ($33): Access for three months, about $11 per month.

• Yearly Pass ($99): Access for one year, about $8.25 per month.

• 2 Year Pass ($159): Access for two years, about $6.63 per month.

Every pass includes the same full feature set: unlimited AI rewrites, custom writing styles, audio file uploads, recordings up to 15 minutes, SuperSummaries, folders and tags, and both Zapier and webhook integrations.

None of the passes renew automatically, so you decide whether to renew once your access period ends, and notes you saved during that time stay yours to keep.

Letterly offers three simple pricing options to fit different needs.

• Monthly Plan ($19.99/month): Billed every month with no free trial, giving you full access on a flexible basis.

• Annual Plan ($79.99/year): Comes with a 7 day free trial, then renews yearly. This works out to about $6.67 a month, saving roughly $159.89 compared to paying monthly.

• Lifetime Plan ($199.99 one time): A single payment for permanent access, with no recurring charges.

Every plan includes best in class transcription, unlimited recordings and AI rewrites, and access across unlimited devices on both mobile and desktop. The Lifetime plan tends to pay for itself compared to the Annual plan after about two and a half years of use.
