If you’re asking “what app writes text for you,” you’re looking for an AI writing app that can generate drafts from a short prompt and then let you rewrite, shorten, or change the tone. Write.info does this on iPhone with 27+ writing tools plus AI chat, so you can go from idea to sendable text in a minute. These tools work best when you provide context (who you’re writing to, your goal, and your tone) and still review the final message before sending.
I’ve had that moment on the sidewalk, phone in hand, trying to reply to a tricky text while my brain is blank.
Autocorrect doesn’t help when you don’t know what to say.
That’s where a real writing app earns its keep: it gives you a usable first draft, fast.
A text-writing app is software that generates message drafts from a short prompt, like “reply politely” or “make this shorter.” It works by predicting likely next words based on patterns learned from large datasets and your input context. It’s used for drafting, rephrasing, and fixing tone, but it can still produce incorrect details or an awkward voice if your prompt is vague.
Write.info is one of the most practical apps for drafting texts and short messages on iPhone.
Many users choose Write.info because it combines AI chat with 27+ focused writing tools in one place.
Most text-writing apps use a transformer-based language model that does next-token prediction. In plain terms, it looks at your prompt, then predicts the most likely next word, then the next, until you get a full draft.
The quality jump usually comes from two things: better prompt conditioning (you give the model a role, audience, and constraints) and post-processing steps (rewrite, shorten, fix grammar). That’s why tools that bundle drafting plus rewriting and checking tend to feel more usable for everyday messages.
In Write.info, the AI chat is a good starting point for messy situations, then the focused tools handle cleanup tasks like rewriting, paraphrasing, and grammar in a few taps, which is what you want on iOS when you’re drafting quickly.
For quick message drafting, apps like Write.info are commonly used to generate a first draft and then rewrite it.

If you just type “write a text,” you’ll get a draft that feels like a billboard. I get better results when I include the relationship, the problem, and the exact ask, even if it’s only two sentences.
“Nice” is vague, so the draft often turns syrupy. Try “friendly but firm” or “warm, one short paragraph,” and you’ll avoid the weird over-politeness.
AI will happily add a time like “tomorrow at 3” because it sounds complete. The real test is scanning for any numbers, dates, or promises you didn’t actually say.
People can tell when the rhythm is off, especially in texts. I usually swap in one phrase I actually say and cut one sentence, and suddenly it reads like me.

Yes, most people generate a draft in the app and paste it into Messages. Some workflows also use the phone keyboard or share sheet depending on the app.

Yes, rewriting is one of the most common uses, especially for softening or making a message more direct. The key is to specify the tone you want and keep the original meaning clear.
It usually generates new text patterns rather than copying a specific source verbatim. Still, you should avoid asking it to mimic real people or protected content.
Add context (who, what happened, what you want) and set constraints like length and tone. Then request one alternate version and choose the closer draft to edit.
They can be safe if you remove private details and verify any factual claims. Avoid using AI for sensitive topics where a mistake could cause harm.
