Sounds like you
It learns how you actually write from the replies you send: length, emojis, capitals, slang. Set a different tone per app, so LinkedIn never gets your dating voice.
AI reply keyboard for iPhone
Don’t overthink it. Just reply.
ReplyKey reads the conversation on your screen and writes the reply in your own voice. Dating apps, WhatsApp, LinkedIn, X, Reddit, email: anywhere you can type.

- Remembers who is who, so a reply to Ewa never sounds like one to Kasia
- Your style: playful, dry, lowercase, whatever you actually are

Daniel · Recruiter

✨ 3 replies, the first is already in the field
- InterestedThanks Daniel, glad it landed! Does Tuesday or Wednesday afternoon work for 20 minutes?
- Not nowThanks for thinking of me! I’m happy where I am for now, but let’s stay in touch.

Replies worth posting.
- Reads the post and the thread under it, not just one line
- Agree, push back or add something useful, in a sentence or two
- Shorter in one tap, because nobody reads a wall of text

Unpopular opinion: nobody actually reads onboarding screens. Change my mind.
✨ 3 replies, the first is already in the field
- Push backPeople skip screens, not moments. Show one tip the second it’s needed and they read every word.
- AgreeSame. The best onboarding I’ve seen was an empty state with one good button.
- AddRan this test once: 3 screens vs 1 inline hint. The hint won on activation by a mile.
WhatsApp, iMessage, Messenger, Telegram, group chats
Never leave anyone on read.
- Replies in the language of the chat, Polish to mum and English to the group
- Plans, birthdays, “sorry I missed this” texts in seconds
- Warmer or funnier in one tap when the first try is too flat

Twenty minutes of drafting. Or one tap.
Typing, deleting, rereading their message for the fifth time. It writes the reply you would have landed on, while you still feel like answering.
You, 1:12 a.m.
ok you will NOT believe what Marco just did
You, with the keyboard

How it works
Three steps. Zero copy and paste.
No switching apps, no uploading screenshots, no prompt to write. It lives in your keyboard, right where the reply goes.
- 01
Press once.
Start it from the Action Button, Back Tap or Control Center. It reads the screen only while it’s on, iOS shows when it is, and the same press turns it off.
- 02
Scroll like you always do.
Their profile, the thread, the post you want to answer. It picks up who you’re talking to, what was said and the tone of it.
- 03
Tap ✨ and it’s written.
Three replies appear above the keys and the best one is already in the message field. Edit it, tweak it with one tap, then you press send.
Built in
Built around how you text,
not how a bot would.
One-tap tweaks
Shorter, warmer, formal, another language, or your own instruction. Save the ones you use as chips. Undo goes back step by step.
Remembers who’s who
One look at a profile or thread and it knows the person next time, so replies pick up where you left off. Prefer it forgets? Simple mode remembers no one.
Every language you text in
Replies come in the language of the chat and translate with one tap. Autocorrect switches between English and Polish as you type.
Or just say it
Tap 🎤, talk, and your words are typed at the cursor. Handy when your hands are full.
Snippets
Your handle, number, address or usual availability, two taps away.
History
Everything the keyboard typed, by day and person, searchable.
A real keyboard, too
Autocorrect, word suggestions, space-bar cursor, accents and haptics. Typing works offline.
Privacy
Your conversations stay yours.
A keyboard sees a lot. This one is built to see only what it needs, only when you ask, and to keep the rest on your phone.
- You always press send
ReplyKey writes the reply and puts it in the field. It never sends a message, likes or posts anything for you.
- Reads only when you ask
Screen reading starts with your press, iOS shows when it’s on, and the same press stops it.
- People stay on your iPhone
What it remembers about the people you talk to is kept on your device. Simple mode remembers no one.
- Your Photos stay clean
Screens it reads never land in your photo library.

Which apps does it work in?
Any app where you can type and switch keyboards: iMessage, WhatsApp, Instagram, dating apps, LinkedIn, X, Reddit, Discord, Telegram, Slack, email, forums and comment boxes. A few fields, like passwords and some banking apps, only allow Apple’s keyboard; that’s an iOS rule.
Will it send messages for me?
No. ReplyKey only puts text in the message field. You read it, change it if you like, and press send yourself.
Does it watch my screen all the time?
No. It reads the screen only after you start it (Action Button, Back Tap or Control Center), iOS shows when it’s on, and the same press stops it. You can also use single screenshots instead.
Why does it ask for Full Access?
iOS calls a keyboard’s network access “Full Access”, and the AI needs it to write replies. Plain typing, autocorrect and suggestions work without it.
Will the replies sound like me, or like AI?
Like you. It picks up your length, emojis, capitals and slang from the replies you actually send, and you can set a different tone per app. If one misses, one tap makes it shorter, warmer or more formal.
Which languages does it speak?
Replies come in the language of the conversation, and you can translate a draft with one tap. Autocorrect handles English and Polish today.
Is it free?
Yes: the keyboard and 5 AI replies a day are free. Pro adds unlimited replies, memory of everyone you talk to and several screens per reply, with 7 days free and no card to start.
Is there an Android version?
Not yet. ReplyKey is iPhone only for now, on iOS 18 or later.
