GrammarBot is a MacOS app that checks your English grammar and suggests a corrected version, fixing misspelled words, typos, or grammar mistakes. It works with a local AI model, so there's no need for subscriptions or an internet connection.
Hi Product Hunt! English is not my first language, but I communicate in English most of my day: Slack, X, emails, reddit, etc. And I always double-check my English before posting or sending a message. So, I built an AI app to help me with that!
The cool thing is that it works with a local AI model, so it doesn't use Internet connection, and the information doesn't leave my laptop.
The techy story:
I was blown away the first time I ran a local LLM, how is it possible that "ChatGPT" is running in my laptop like every other app? I started digging into that and released an open-source app to download and run local LLMs. But, like all the other apps at the moment, it was kind of confusing for a regular user, with the continues release of new AI models, each one with a more confusing name, it was hard to know which one to choose. So, I decided to build the first commercial local LLM app that's easy to use for normal humans. I needed a simple, but useful task, and to scratch my own itch: grammar checker. This is my first product trying to use local LLMs to solve real problems in a simple manner. I expect to launch more soon (I'm already building the next one). DMs are open if you have any app in mind that you would like to run locally in your computer.
For the curious, it's built in Rust.
@julioandresdev Congratulations on the launch of your local LLM app for grammar checking! 🎉 It's fantastic to see how you've harnessed the power of AI to simplify language correction for everyday communication. Here's to empowering users to communicate confidently in English, without compromising privacy or connectivity. 🚀💬

This pitch is amazing. Sold me with just 1 sentence: 'Write flawless English with AI, no subscriptions, offline'
My second question after seeing this was 'Which friends can I send this too' and that was answered in the FAQs :)
I'd love if the M1, M2, M3 aspect could be highlighted a bit more? https://shot.screenden.com/RstjnMcz
Just would help people know instantly who they can share it with/who can use it.
Brilliant idea again, congrats on your launch!
Hi Julio, your GrammarBot sounds like a game-changer for non-native speakers and privacy-focused individuals alike! Keeping everything offline is a big plus. I'm intrigued by the use of a local AI model – it must have been challenging to implement. What inspired you to choose Rust for building GrammarBot? Can't wait to see what other local LLM apps you're working on!
@alex_dulub Thanks Alex! it was challenging. I did it in Rust because I wanted to be super fast, native-fast, and also to be able to compile to different platforms (MacOs, Windows, Linux). I had experience with Rust so I knew it could be possible, it was challenging and fun.

Have you considered the App Store? I could not find it there. There is people that only want to download apps there. There is a layer of security and also makes everything easy to deal with different computers.
@narcismirandes Yes, I have considered it. I have some iOS apps, but I haven't looked into MacOS apps yet. I wanted to see if there is any interest first before going through the hassle of app store reviews, haha.

My only goal when writing is to get close enough for spell check to guess what I meant to say..... I can always use and glad to offer my customers a tool to make life just that much less stressful and easier.
any chance this will be ported over to Windows?
@ipaparazzo_app Thanks Loane! Someone else already requested it for French, the thing is that I don't know French so I wouldn't know if it's making a good work 😅 but I will give it try with other languages.

Congrats on the launch! This is a great competitor to the other tools out there, which are online like Grammarly.
