Executive Summary of "TeumTeum" (틈틈이)

"TeumTeum" is a browser-based extension and terminal utility designed to monetize the idle "waiting time" that occurs while users await responses from Large Language Models (LLMs) such as ChatGPT, Claude, and Gemini. By injecting non-intrusive advertisements into this latency window, the platform converts otherwise wasted time into monetary rewards for the user.

Core Methodology and Operational Mechanics

1. Latency-Based Ad Injection
The core mechanism leverages the temporal gap between a user’s prompt submission and the start of token generation. The system monitors the state of supported LLM web interfaces (chatgpt.com, claude.ai, gemini.google.com). When a request is sent, an ad slot is dynamically rendered above the input field. Once the LLM begins streaming its response, the advertisement is automatically removed to ensure that the user’s reading experience remains uninterrupted.

2. Privacy-Preserving Context Classification
To maintain user privacy, the system employs on-device processing rather than cloud-based analysis. The extension performs a local analysis of the prompt to identify the general "field" or topic (e.g., travel, finance, technology). No raw chat logs are stored or transmitted to external servers; only the classified category labels are sent to the ad engine to ensure relevant ad targeting.

3. Economic Model and Revenue Sharing
The platform operates on a transparent revenue distribution model based on "effective impressions." When a user views an ad during the response latency period, revenue is generated, which is partitioned as follows:

• User (50%): Credited directly to the user's digital wallet.
• Publisher/Content Owner (30%): Reserved for the creators of the content that the AI references.
• Platform (20%): Operational overhead for the service.

The distribution formula for a single ad impression $R$ can be represented as:
$$Reward_{user} = R \times 0.5$$
$$Reward_{publisher} = R \times 0.3$$
$$Reward_{platform} = R \times 0.2$$

When a user accumulates a threshold of $T = 2,000$ KRW, they can redeem the balance for a coffee gift certificate. The system avoids traditional user registration, relying instead on a browser-side wallet and a simple phone number verification process for coupon delivery.

Technical Integration and Accessibility

• Web Browser Environment: The extension utilizes standard Chromium APIs, making it compatible with Google Chrome, Microsoft Edge, and Naver Whale. It currently excludes mobile browsers and Safari due to architectural limitations regarding extension support.
• Terminal Integration: For power users, the system extends its functionality to the terminal via "Claude Code." Users sync their wallet by inputting a unique token generated in the browser extension into their CLI environment, allowing the terminal’s status bar to display real-time ad content and accumulation metrics.
• Non-Invasive UI Policy: The service strictly adheres to a "non-blocking" design principle. Advertisements are confined to a dedicated slot, ensuring they do not overlay the output area, modify the page structure, or interfere with the AI’s primary response generation.
