HanakoPro

HanakoPro is a Windows desktop application that lets you have conversations with an AI assistant while it can also read and edit files on your computer, run terminal commands, and remember things across sessions. It is a modified version of an open-source project called Hanako, built on top of version 0.194.2 of that project. The README is written in Chinese, and the app appears aimed at developers and graduate students who want a more capable daily AI coding companion.

The main additions over the original Hanako are practical quality-of-life improvements for people who use AI to write or edit code. When the AI changes a file, HanakoPro shows the before-and-after differences side by side in the chat window, so you can immediately see exactly what changed. As the AI writes to a file, the edits appear character by character in real time, like a typewriter. A built-in terminal panel streams command output directly into the conversation, so you can watch a program run without switching windows.

Several conversation-flow features were also added. You can retract a message you sent, which lets you undo a mistaken instruction and adjust it. You can also add a new instruction while the AI is still typing its response, rather than waiting for it to finish. The interruption handling was improved so that stopping the AI mid-reply does not corrupt the conversation or lose context.

The memory system was redesigned to show each saved memory item as a separate entry and let you jump directly to the conversation turn where a memory was created. System prompts and tool descriptions are fully exposed and editable, so you can change how the AI behaves without any hidden instructions. A desktop companion feature adds a small on-screen figure you can query without opening the main window.

Installation on Windows uses a standard installer. Running from source requires Node.js 22 or later and npm 10 or later. The project is released under the Apache 2.0 license.
