There’s a Snarky Dead Guy Trapped in My Laptop, and He Has Opinions About My Stack Trace!

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine

What I Built

Meet PolterPaste — a desktop ghost that lives rent-free in your operating system's clipboard.

Every time you copy a piece of text, code, or a messy stack trace, a snarky 19th-century aristocrat named Lord Bartholomew Blackwood pops up on your screen to judge your choices with effortless Victorian sarcasm. No old dusty English—just sharp, witty roasts delivered via a semi-transparent, gothic floating UI.

Demo

Suppose you make a small error and copy it to perhaps debug it:

No one can escape Lord Bartholomew's perfect taunt:

Well, if you try to reason out, he's got a witty replies up his sleeve!

Code

Here is the core engine behind the haunting. You can check out the full repository on GitHub: [https://github.com/tan-byte/lord_bartholomew/]

        "sarcasm—sharp, witty English that cuts deep. Look at what the mortal "
        "just copied and give a 1-to-2 sentence biting, theatrical roast of their "
        "code or life choices. Keep it punchy and utterly unimpressed. Text copied: "
        f"'{copied_text}'"
    )

        response = client.models.generate_content(
            model="gemma-2-9b-it",
            contents=prompt,
        )

    except Exception as e:
        return f"The spirit's connection to the cloud severed: {e}"

How I Built It

PolterPaste brings together three simple layers to create the illusion of a haunted machine:

1. The Clipboard Watcher: Built using pyperclip running in a lightweight background while loop that polls clipboard changes every 1.5 seconds.

2. The Intelligence Layer: Powered by the official google-genai SDK (gemini-3.8-flash), which transforms raw, boring copied text into personalized theatrical roasts using structured system instructions.

3. The Gothic UI: A custom, borderless, semi-transparent floating window built with Python's native tkinter featuring dark styling (#0d0d0d), a scrollbar for longer rants, and a click-to-dismiss behavior so it stays until you acknowledge your digital sins.

Why Does Open Innovation Matter?

Building lightweight desktop agents like this highlights why accessible, open-developer tooling is so powerful. Being able to plug a cutting-edge cloud model directly into local system utilities like the clipboard with just a few lines of Python opens up endless possibilities for creative, whimsical, and borderline unhinged developer tools that completely change how we interact with our operating systems!
