Audio Diary is a voice journaling app from Soliloquy Apps Ltd, a London company. A user speaks an entry instead of typing it, and the app transcribes it and runs AI analysis over the text. It runs on iOS, Android and macOS, with a web app at app.audiodiary.ai, and the site cites more than 500 App Store reviews and more than 1,500 Google Play reviews.
The named AI features are automatic entry summarization, goal suggestions drawn from diary content, dream analysis, custom AI tagging and smart transcription and analysis. The paid tier raises recording time tenfold and adds deeper AI analysis, custom tagging, custom themes, dream analysis and 10 photo uploads a day. It is subscription-only, with no lifetime option.
A free plan is available. Audio Diary’s own site lists no prices, so the paid figures here come from app-store listings: $10.99 a month or $59.99 a year in USD. Confirm the current price in the store before subscribing.
