What is line-chat-maker?

This project is a free, offline tool for creating LINE style chat screenshots for entertainment and illustration purposes, not for creating fake evidence or deceptive screenshots. You edit everything directly on the page: bubble text, display names, timestamps, and read receipts can all be clicked and changed in place. The tool includes the visual details that make a LINE conversation look right, like quoted replies, emoji or sticker style reactions, a collapsed message separator, date dividers, and automatically hiding repeated avatars for consecutive messages from the same person. You can toggle a phone style frame around the conversation, switch between group chat and one on one layouts, and pick from six visual themes ranging from a sticker album look to a realistic LINE style, each with its own colors, bubble shapes, and animations. Fonts can be swapped too, including any font already installed on your computer if you are using a Chromium based browser. A built in AI assistant can write a full conversation script for you from a short prompt, using a two stage process where one AI writes the script and a second AI grades it against several criteria before it is accepted, and a separate AI feature can generate matching images for stickers or avatars in the conversation. You can bring your own API key from several providers, or use the site owner's free but rate limited proxy. There is also a WebMCP integration for browser agents and a downloadable Agent skill file that lets an external AI directly operate the tool through a defined script format. Finished conversations can be exported as a PNG image or an MP4 video, or embedded directly into a blog or webpage. To discourage misuse, every exported image and video carries invisible watermark data hidden in ways that survive screenshots and re-compression, along with a separate page for checking whether an image or video was produced by this tool. The author is explicit that this only raises the cost of casual misuse and cannot stop a determined person from removing the marks or fully prevent misleading content. The project runs entirely in the browser with no build step needed, and is released under the MIT License.
