AI writing assistant that learns your personal style to draft emails and content in your voice.
u/imYouOfficial · Reddit
I built an AI writing assistant that learns to write like you. My work emails kept coming out sounding like a robot wrote them. Every AI tool I tried gave me the same polished corporate nothing that read like a press release instead of a guy asking his coworker for a favor. So I built imYou. It interviews you for a few minutes to learn how you actually write and then uses that on everything it drafts for you. Emails, social media posts, and more. It also has a chat function where you can me

I'm not a developer, but I built in about a month. I paid for the $200 Max plan with Claude but I could have probably gone with the $100 Max plan. I've already cancelled since the building is mostly done so I plan to now focus on user growth.

Turn keywords and half-formed ideas into refined prompts through interactive word curation.
u/UniversityIll2916 · Reddit
I built a brainstorming tool where you flick single words by instinct — 30s demo ou type in a half-formed idea. It throws single words at you, one at a time, and you keep / spark / drop each one on instinct — about a second a decision. Sparks are the important ones: the words you can't resolve yet, and the next round follows them hardest. At the end it writes the whole thing up as a prompt you can paste into Claude or ChatGPT. The clip is one real session — seed was "make our team meetings

Detect AI in your writing, revise flagged passages, and rescan to verify changes.

I built an AI detector and I'm not sure the score is the useful part I started building DidAIwriteit.com thinking the most useful part was the sentence level scoring and rescan.
