About

CoDomainer - Chrome Extension for ExpiredDomains.net

CoDomainer is a Chrome browser extension built for domain investors who use
ExpiredDomains.net to find and evaluate expired domain names. It analyzes every
domain listing on the page against a local database of historical retail sales
data sourced from Namebio, giving each domain a liquidity score so investors
can instantly identify high-value acquisition opportunities.


HOW IT WORKS

When you browse any listing page on ExpiredDomains.net, CoDomainer automatically:

1. Extracts every domain name from the table on the page.
2. Breaks each domain into its component keywords using intelligent segmentation
   (CamelCase splitting, hyphen splitting, and Dynamic Programming-based word
   decomposition — e.g. "saasflow" becomes "saas" + "flow").
3. Looks up each keyword in a bundled CSV database of ~100K+ historical retail
   domain sales records from Namebio.
4. Computes a composite Liquidity Score (0–100) for each domain based on how
   frequently its keywords appear in real retail sales, weighted by match
   position (exact, prefix, suffix, middle).
5. Classifies domains into tiers:
     - Highly Liquid (score >= 70) — keywords with strong, proven retail demand
     - Moderate (score >= 40) — keywords with decent sales history
     - Low Liquidity (score >= 20) — keywords with limited sales evidence
     - Illiquid (below 20) — no meaningful retail sales signal


FEATURES
--------

SCOUT (Home Tab)
  - One-click "Scan & Analyze Page" to evaluate all domains on the current page.
  - Domain cards in the side panel showing score, tier, keyword breakdown, and
    reasoning for every domain.
  - Filter chips to quickly view only Highly Liquid, Moderate, Low Liquidity,
    or Illiquid domains.
  - Toggle switches:
      * Keyword Sales Data — Injects a column directly into the ExpiredDomains
        table showing per-keyword sales counts, match type (Exact/Prefix/Suffix/
        Middle), and average sale price.
      * Highlight Table Rows — Color-codes rows on the webpage by tier (gold for
        premium, green for good, indigo for mediocre, dimmed for skip).
      * Sort by Score — Reorders the table rows on the page by descending
        liquidity score.

RADAR (Watchlist)
  - Automatically captures domains that meet or exceed a configurable score
    threshold during scans.
  - Maintains a persistent watchlist across sessions stored in Chrome local
    storage.
  - Enable/disable radar tracking and set the minimum score threshold.
  - Clear watchlist with one click.

AUTO PILOT
  - Automated multi-page scanning — set a number of pages (1–100) and a score
    threshold, then CoDomainer will automatically navigate through listing pages,
    scan each one, and collect matching domains.
  - Telegram Bot integration — sends structured reports of high-scoring domains
    directly to your private Telegram account in batches of 20.
  - Setup wizard with step-by-step instructions to connect your Telegram Bot
    (via @BotFather token and @userinfobot Chat ID).
  - Can run without Telegram in "Radar Only" mode, saving results to the local
    watchlist instead.

SETTINGS
  - Domain Matching Mode:
      * Segmented — Uses Dynamic Programming to intelligently split compound
        domain names into known keywords.
      * Strict — Only matches the entire domain core name as a single keyword.
  - Score Logic Configuration — Full control over the scoring algorithm:
      * Global vs. Positional weight balance (default: 30% / 70%)
      * Multipliers for global sales, exact match, and segment match scores
      * Tier thresholds for Highly Liquid, Moderate, and Low Liquidity cutoffs
  - Telegram Bot management — edit credentials, test connection, or disconnect.
