JevChat-Windows
Local OCR chat overlay that judges intent and drafts replies via LLM.
Offline OCR screen-reader feeding LLMs to generate contextual chat response options.
This is a Windows desktop overlay that reads chat windows via local OCR, evaluates intent, and generates three candidate replies for you to insert manually. It suits professionals and power users managing high-volume desktop chats who want AI-assisted drafting without auto-sending.
What it is
It captures your active chat window using Windows Graphics Capture and runs RapidOCR locally to parse the conversation. A dual-model backend uses one LLM to judge intent and context, and a second LLM to draft three scored reply options that you can paste with a single click.
Who it's for
It suits Windows power users looking for context-aware reply suggestions across chat applications without hooking into app processes. It does not suit non-Windows users, those seeking automated message sending, or anyone unwilling to supply their own API keys.

Our honest verdict
What's great
- Operates entirely via screen capture and local OCR without process injection or account hooks.
- Keeps API keys secure in Windows registry environment variables rather than plaintext files.
- Completely manual sending ensures you retain final control over every message.
- Zero token consumption and zero background calls during idle silences.
Where it falls short
- Requires you to bring your own API keys for both judgment and drafting models.
- Windows 10 1903 or Windows 11 required due to Windows Graphics Capture dependencies.
- No official license stated in the repository metadata, leaving legal usage terms unclear.
Pricing & license
The software is open source and free to download, but you must pay the API usage costs for the external LLM services you configure for judgment and drafting.

FAQ
Does the tool automatically send messages for you?
No, it only populates the chat input box. Sending is always performed manually by you.
Where are my API keys stored?
API keys are written directly to your Windows user environment registry variables and never saved to local config files.
Will this tool get my chat account banned?
It relies strictly on screen capture and local OCR, functioning identically to standard screen-reading software rather than injecting code.
