做了一个 AI 局部修图工具:圈选哪里,就只改哪里 最近在做 InpaintingAI ,目标是把 AI 局部修图做得更直观一些: 1. 上传照片; 2. 圈选或涂抹要修改的区域; 3. 给每个区域写一句要求; 4. 在同一个界面里对比前后结果。 目前适合移除路人 / 物体、修复划痕、替换局部内容。编辑器也支持把多个局部修改拆开描述,尽量减少“一句话改了整张图”的情况。 在线体验: https://inpaintingai.com  还在持续打磨结果稳定性和编辑体验,想请 V 友帮忙看看:你最希望这类工具先把哪个场景做好?如果遇到不自然的边缘或误改,也欢迎直接反馈。

Add a phone number to your intake form so clients can complete it by calling instead of typing.
u/jacobgc75 · Reddit
I made an intake form people can complete by talking on the phone Forms are good at collecting structured answers and terrible at getting the whole story. People leave blanks, write one line, and someone has to chase the missing details later. I built Formnumber to turn an existing intake form into a phone conversation.

Free calculators to help homebuyers understand their offer before submitting.
u/Offer-Buildr · Reddit
I built a free suite of home offer calculators because I felt that most mortgage calculators answer the wrong question I started and run a small free tool called "Offer Buildr" that helps homebuyers understand an offer before their agent writes it. The core builder turns a listing price into true monthly cost and cash to close, then walks the ten decisions in an offer and prints a one page summary to hand your agent. Last week I shipped the piece I wish I had started with: five single-ques

Toss the I Ching coins online to explore hexagrams and search real-time newsfeeds.
richcostello68 · HN
The IChingPortal is a phrase and keyword search platform that queries popular API’s and 1000’s of newsfeeds and filters them through the I Ching frame work. I call Ancient Wisdom through Modern Data.
