Overview

Product summary

Review the store description, core capabilities, and common use cases.

USAGE NOTES:

Whenever your webpage loads, the analysis bar should reload and buffer - this indicates that the Two-Line Eval is active. You may have to re-toggle the extension on-off-on to ensure it is working. By default, the extension is turned OFF whenever you load into a page, so even if you had toggled it "ON" previously, you will have to toggle it "ON-OFF-ON" again to restart the Two-Line Evaluation.

Depending on the side whose turn it is to move, the bar will load a slightly darker/lighter shaded section for each side, which represents the difference in evaluation between playing the best move and the second-best move. It may take some getting used to, but is fairly intuitive.

The best use-case for this extension is for following classical chess, especially where a high-level player may have to make multiple only-moves in a row in a given position.

AI product read

Display a two-line evaluation bar on chess.com that shows the difference between the best and second-best move evaluations.

Helps users follow high-level chess games by visualizing the evaluation gap between the top two candidate moves, making it easier to understand critical moments where players must find only-moves.

User installs extension -> visits chess.com game/event/analysis page -> clicks extension icon to toggle ON -> extension injects a two-line eval bar into the page showing evaluation differences for best and second-best moves -> user can toggle OFF via popup to hide the bar.

Target users: Chess enthusiasts / Chess players following high-level games / Chess analysts and commentators

The extension only works on chess.com pages; behavior on other sites is not applicable. The analysis assumes chess.com's DOM structure remains stable; if chess.com changes class names or evaluation display, the extension may break. No server-side components were found, so all logic is client-side DOM manipulation.

Monetization

No paid features detected

The extension is free with no paid features, subscription gates, or payment integrations. The keyword 'pro' found in _metadata/verified_contents.json is part of Chrome Web Store's internal verification metadata (treehash per file), not a product feature. There are no references to Stripe, PayPal, license keys, upgrade prompts, or premium tiers in the extension code.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself does not implement any login mechanism. It relies on the user being on chess.com, where the extension reads evaluation data from the page DOM. While chess.com may require an account to view some games, the extension itself does not enforce login, nor does it have its own account system. The core workflow (toggling the eval bar) works without extension-level authentication.
