Automatically detects and highlights Japanese stock names (銘柄) on any web page, showing stock charts and basic info on hover

Japanese stock traders reading financial news, articles, or forums need to quickly identify stock names and look up their charts/data. This extension eliminates manual copy-paste to financial sites by automatically detecting and marking stock names inline.

1. User installs extension. 2. Browses any Japanese web page. 3. Right-clicks → selects '銘柄をマーキング' (or auto-marks if enabled). 4. Page HTML is sent to extvps.com server for NLP analysis. 5. Server returns detected stock names/codes. 6. Extension highlights stock names on page with colored background. 7. User hovers over highlighted name → tooltip shows stock details and up to 4 charts. 8. User clicks ▼ menu → quick links to Yahoo Finance, Twitter search, Yahoo bulletin board, Kabutan, Shikiho.

Target users: Japanese stock traders / Individual investors researching Japanese equities / Users reading Japanese financial news and forums

Server-side NLP logic at extvps.com is opaque — cannot verify stock detection accuracy or data source
The admain endpoint delivers server-controlled HTML which is inserted into pages (potential ad/tracking concern)
Cannot verify if extvps.com imposes any rate limits or usage caps that could affect free usage

Monetization

No paid features detected

No evidence of paid features, premium tiers, subscriptions, or payment gates in the extension. All settings in popup.html (chart URLs for 4 charts, auto-marking, summary display, chart color/size/swap/def options) are freely accessible with no restrictions. The 'pro' keyword hits are false positives (font-family 'Hiragino Kaku Gothic Pro' in CSS, variable 'gl_procstart' in JS). The extension monetizes via server-delivered ads (admain endpoint) rather than feature-gating. No upgrade prompts, no billing references, no payment platform integrations found.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension auto-generates an anonymous user_id via POST to https://extvps.com/createuser/ on first use (common.js:95-116). This is a server-side anonymous tracking identifier, not a user-authenticated account. No login form, no credentials collection, no authentication flow exists in the codebase. The user_id is created automatically with no user input and stored locally. The core workflow (right-click → mark stocks → hover for charts) works without any login.
