ReplyContext
Read full descriptionHide full description
Reply to texts, chats and emails in your own words. Share the message you got, say roughly what you want to answer, and ReplyContext writes one reply you can send as your own. HOW IT WORKS β’ Share a message from any app, paste it, or add a screenshot of the chat. β’ Type or dictate the gist, like "not today, Friday is realistic". β’ Get one reply in your language and tone. No list of variants to compare. β’ Ask for changes such as "shorter" or "warmer", or tap Polish to fix grammar and punctuation. β’ Copy it and paste it into WhatsApp, Messages, Mail, Outlook, Slack, Microsoft Teams or wherever the conversation is. ReplyContext never sends anything for you. NOTHING YOU DIDN'T SAY ReplyContext keeps your meaning. It is built not to add facts, promises, deadlines, apologies or feelings you did not state. If something the reply needs is missing, it asks you one short question instead of guessing. POLISH YOUR OWN DRAFT No message to answer? Type or dictate a rough draft and get it back as a clean message, with the smallest changes needed. MADE FOR β’ Answering clients and colleagues from your phone, in work chats and email β’ Messages you would otherwise reread three times before replying β’ Writing in a language that is not your first DICTATION THAT KNOWS YOUR NAMES Dictate for up to 60 seconds. Add names and terms to your personal vocabulary so they are spelled right. Before the first recording, the app asks for your consent to send the audio and your vocabulary to Google Gemini for transcription. The recording is not kept on your device afterwards. PRIVATE BY DEFAULT β’ Captured messages are used to write your reply and are not stored on ReplyContext servers. β’ A reply you haven't copied stays on your iPhone until you delete it. β’ Copied replies stay on your iPhone for 30 days by default, with what you captured for them. You can shorten this or turn it off. β’ Optional memory is off by default. When on, it keeps three numbers about how you edit replies, which you can see and delete. It never keeps your text. An account and an internet connection are required. Eligible new accounts start with free credit. After that, choose a weekly, monthly or yearly subscription in the app. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your Apple Account settings. Terms of Use: https://www.replycontext.com/terms Privacy Policy: https://www.replycontext.com/privacy
