Show HN: Wisp – open-source private desktop AI overlay with MCP support
I built Wisp because I kept alt-tabbing between my editor/browser/docs and chat apps, copying context over, waiting for an answer, then copying the result back.
Wisp is a desktop overlay for using AI from whatever app you are already in.
-You can prompt with your choice of context (Text, screenshot, snipping, active app etc) in a few key strokes
-For longer back-and-forth, it can open into a full chat window.
-Supports hold-to-talk voice queries, dictation into any field, local TTS,
-Can pastes the result back directly over selected text.
-Data is local first, and nothing is sent to provider without your permission
-It supports 20+ local and remote providers, including OpenRouter, Groq, Gemini, Ollama, and LM Studio.
-Runs on Windows, macOS and Linux
v0.9 Added Wisp Context Server: trusted MCP clients can read selected text, clipboard, active window, browser-page text, and screen snippets.
I no longer have access to Mac hardware, so I would especially appreciate macOS testing. Bug reports and ideas are appreciated.

Show HN: JMT – Java Based MultiTool
I want to show people my brainchild, which I’ve really enjoyed developing. This app is written in pure Java, and—even though it doesn’t have many features available right now—it has everything you need right at your fingertips. I’m looking for people who will appreciate this type of app and are willing to share their thoughts on it. I’d really love to get feedback on the design, potential features, what’s missing, and what’s completely unnecessary.
