Hello, Product Hunt 🙌🏻

I’m Daniil, I work as a software engineer with passion to create product that will be genuinely saving people’s time everyday. Today I’m happy to introduce ClarifierAI, an app that was born from my own needs.

🧩 Product Story

I found myself constantly switching between AI apps just to refine or translate my messages or posts. Sometimes before sending message to someone, I was double checking with AI if message sound polite or clear enough. I was that so much, and eventually I created separate workflows for each task to save some extra time and not explain AI every time what it want him to do with my text. But the copy-pasting between apps was still very slow, and I wanted to save even more extra time, so I combined those workflows into one simple IOS keyboard extension, and now it saves me a lot of time. 

I immediately got 250+ beta testers from Reddit, talked to them, and used their feedback to iterate on the countless edge cases, so today I can finally share a polished product with you.

📱 What is ClarifierAI?

It’s an IOS custom keyboard that improves, translates and changes tones for your text in any app, enabling you to seamlessly utilize AI and save a lot of time. This app respects your privacy and common used keyboard, switch to ClarifierAI only when you need to work on your text. My ICP is professionals and anyone writing in a language that isn’t their own. It supports 113 languages so far.

Comment highlights

Tested it briefly and the keyboard integration feels super practical.

How does it stand out compared to Apple Intelligence for rewriting and tone adjustments?

Having the app as a keyboard is a smart solution. It’s been very helpful in two aspects: I write in two different languages, it improves my writing on both. I also have been using a lot the dictation to make my writing faster, and I love how ClarifierAI corrects the text instantly after the dictation.

One final thought: congratulations to Daniel for the app launch and for the strong focus on improving his product: he has been very open to suggestions and feedback, and any comment is welcomed and taken seriously.

Wonderful app with great potential. Simplifies a couple of workflows for me to a great extent. Every time I’m writhing something to a couple of serious relationships - boss, new contacts, work folks etc, and the topic is sensitive I always run my text through ChatGPT to make sure I’m not being verbose, that I have the right tone, and further that I’m not accidentally offending someone. This app prevents that app switch to ChatGPT and lets me work within the app. Great stuff and it’ll save a lot of time

Typically, I would have run my review through ChatGPT to tighten it up, but down here, I got this response within a second with zero app switching!!

Wonderful app with great potential. It significantly simplifies a couple of workflows for me. Whenever I'm writing something to important contacts—like my boss, new connections, or colleagues—and the topic is sensitive, I always run my text through ChatGPT to ensure I'm not being verbose, that I have the right tone, and that I'm not accidentally offending anyone. This app eliminates the need to switch to ChatGPT and allows me to work within the app. Great stuff, and it will save a lot of time.

Congrats on the launch!! I’m really tired of having to jump between apps just to translate a simple message, so this is a lifesaver. One thing I'm curious about does ClarifierAI actually learn my own typing style over time to make translations sound more like me, or is it just based on the tone I select? Great job guys!!!

I like the idea but keyboard extensions always make me a bit cautious how is privacy handled and sensitive text? Is anything stored?

Chúc mừng nha

Ứng dụng rất hữu ít với những người chưa giỏi ngôn ngữ như mình mong nhà phát triển tiếp tục cập nhật nhiều hơn.

Hi Daniil!

I have been an app curator for many years (not to confuse with an app hoarder!), testing betas since long ago - both Android and iOS. At the same time, very cautious with the personal data used by these apps. A keyboard app is a first class to handle personal data, for what I’m very cautious - and everybody should - to use in a daily basis.

Your app can help with a major situation: comunication in various languages in the right way. I'm putting my cents in your app if you keep the app with the “zero data retention” privacy as your app is clean and user friendly, plus tackles a necessary thing: effective communication.

I will follow this great project to see how amazing can keep evolving!

This app is really essential for Vietnamese speakers like myself. It would be even better if it integrated directly into the iOS keyboard to check for errors while typing.

I've been giving ClarifierAI a test run over the past few days and I'm very impressed by it so far. I've fed it several raw "brain dumps" and asked it to tighten and tidy them up and it's done so very well. It's also great to be able to accept or reject suggested amendments at an individual level because not every single suggestion is 100% correct. But so far it seems like one of the relatively few such apps that properly delivers on what it promises. I've only tested the translation facility briefly as I haven't had a proper need for it yet, but it worked well when I did try it translating from English to the only other language I vaguely understand. It's a really good app and I'd definitely recommend giving it a try if you want to get your points across as clearly as possible. Good luck with the launch!

Hi Daniil,

Tested and it work stupendously good, love that it work seemlessly with the keyboard and it supports my native language, even understood the usage of shortform in our daily conversation.

Congrats on the official release!

Hi I can surely say that this is my favorite app for last half year  My favorite function is translate, and it most helpful in my work chat and online shopping on Chinese markets such as taobao and other. And I’m not using any translator now cause I don’t like switching between apps. Now I’m on vacation and using Clarifier only for shopping. It saved me 1,5 hour (based on build in analytics) of absolutely non active usage. And I can say that this is super crazy🤯 I’ve tried a lot of same apps but this one is fastest. Also personally I hate adding new keyboard cause it’s 100% would not be that good as Apple’s and I love my emoji section which is not be included. It’s more comfy for me to just switch like between languages. What’s next step? Could you add it on MacOS?

Hello Daniil,

I’m looking for an iOS keyboard that lets me translate and proofread smoothly. Apple Intelligence works quite well, but it isn’t well integrated into the iPhone’s native keyboard (you have to dig through a menu for simple tasks). ClarifierAI – et voilà! It perfectly addresses Apple’s limitations and seems a cut above the competition. Watch this space!

Congrats on the launch @dan_pak !

The voice-to-text feature is where this really shines for me. I used to juggle between Willow and Wispr Flow. With ClarifierAI I just talk in German, switch mid-thought to English, and it handles it seamlessly. That alone replaced two apps for me.

Few questions:

  • Any plans for custom tone presets? Like saving a “professional email” tone vs. a “casual” tone so I don’t have to adjust every time?

  • Would love to see some kind of personal dictionary or style memory over time — so it learns that I want to write “color” not “colour”, or “Grüsse” instead of “Grüße”, for example. Anything like that planned?

This has real potential to become the default writing layer on iOS. Rooting for you — keep building!

Hello Daniil,

Congratulations on the launch! This is the app I was hoping that iOS would build-in systemwide. It is simple yet always works. I have one more request though, any plan to integrate snippets and system clipboard history?

Hello Dani,

how does the keyboard handle privacy, especially with sensitive text like passwords or personal messages?

Thank you so much for this great app

Mahmoud

Simple idea, I like the focus. Do people actually stick to the yes/no approach, or do they want more details over time?

Hey Dani, congrats on the launch. I really feel like this is shaping up to be the ultimate transcription app for iOS. My main goal lately has been to stop typing completely and just use voice dictation. I've already found my favorite app on Mac, and 90% of what I write now is by voice. 

I barely touch my keyboard anymore. I really want to do the same on my iPhone, but I hadn't found anything truly effective until now.

I have been using clarifier.ai for a few days, and there is a feature that I find lacking. It could be interesting to add a dedicated line for punctuation just below the "Improve," "Translate," "Clarify," and other buttons. When using the text-to-speech feature, some punctuation is sometimes missing, and this would allow for quick additions.

I think It would also be helpful to have a "Delete" button to quickly remove a word in case of an error, without having to return to the standard keyboard.

I also have a quick feature suggestion regarding translations. Right now, it seems to default to a single direction based on the input. It would be incredibly smooth if we could pre-select our favorite target languages in the app settings, and then simply long-press the "Translate" button on the keyboard to bring up a quick popup list. You’d just hold, slide to the language you want (like switching to Portuguese on the fly), and release to apply. I think that would make the UX so much better!

Great job on the release.
