ImproveThis.ai

Most writing tools fix your sentence. ImproveThis fixes it for the person receiving it.

You save the people you write to most, like a client, your manager, a colleague, and each one builds a profile over time. It learns that one prefers no greeting and three sentences, while another reads that same directness as rude. The more you use it for someone, the closer the output gets to what actually works with them.

Paste a rough draft, pick who it's for, choose a tone. There's also a decoder for the other direction: paste something you received and find out what they probably meant. Built for freelancers and anyone whose messages carry weight. Chasing an invoice, pushing back on scope, telling a client something slipped. Free tier, works in 50+ languages.
