About
Most word-of-the-day apps stop at the definition. Idiolect starts with what happens next: using the word.
Tell Idiolect where words matter to you, how you want to sound and what you already know. It chooses one useful word for your day and explains why that word fits.
Use the word in a conversation, message, email or piece of writing. Later, say or type the sentence you used. Idiolect responds with concise feedback on meaning, phrasing and tone. It can recognise a valid alternative sense, suggest a more natural fit or ask for context when the sentence is ambiguous.
Your words collect in a private lexicon, alongside the sentences in which you used them. After days or weeks, earlier words return without the definition in view so you can see what stayed.
WHAT IDIOLECT DOES
• Chooses words around your goals, interests and natural voice
• Checks which words you already know
• Gives one focused word rather than an endless feed
• Lets you report back by voice or text
• Offers AI feedback without scores or leaderboards
• Keeps your own examples in a personal lexicon
• Brings words back for later recall
• Sends reminders at times you choose
There are no points to collect and no streak to protect. Miss a day and nothing breaks.
Idiolect is for people who already use English comfortably and want more precise, expressive language for conversation, writing, relationships, interests or work. It is not an English course, dictionary or exam-prep app.
One full daily cycle is available before membership. Monthly and annual memberships include a 7-day free trial. Your App Store purchase screen shows the current price and renewal terms before you subscribe.
