Show HN: Content Reviewer for Websites (typos, grammar, etc.)

Hello HN, my main idea with Spelltastic is to run a Grammarly scan on the entire website. I never expected it to become successful (it is not), I just made it to learn React + UI/UX development.

After building the product, I found marketing to be a lot harder than building the product (the gap is increasing thanks to "vibe-coding"). I got completely bored with the loop of finding emails from aggregators -> sending cold emails -> maintaining mailing lists, etc. I had this ideological block of not using any cold emailing services or sales people or any other automated way (LinkedIn Automation, Ads, etc), since I hate those.

Eventually, I realised that checking for spelling mistakes or grammatical issues is more like a vitamin than a painkiller (for most). I couldn't spend time marketing it properly to web dev agencies or SEO people who may have this as a genuine pain, So I have decided to open-source the core implementation of Spelltastic, which is a basic workflow involving Puppeteer (to extract and highlight spelling mistakes) and gpt-4o (for spellchecking) + Dashboard to visualise the reports.

I am happy to have finally built a good-looking product (I am a backend guy btw) and released it. All thanks to Cursor. More importantly, around 30+ people have used it (mostly indiehackers) to find important mistakes in their content.

Check out the repo/product and let me know what you all think. Thanks!
