Provide instant access to private market company and investor data while browsing the web

Eliminates the need to switch tabs or manually search for company/investor information by overlaying Gain's database directly onto the user's current browsing context

User browses a company or investor website -> Extension detects the entity -> Extension fetches data from gain.ai RPC API using user's auth token -> Extension displays relevant Gain profile data via overlay or popup

Target users: Investors / Financial analysts / Private market professionals / Business researchers

The extension code is heavily minified/obfuscated, making detailed feature analysis difficult.
Cannot confirm if the destination service (gain.ai) offers a free tier or if all features require a paid subscription, as billing logic is server-side.
The 'identity' permission suggests OAuth, but the specific flow (e.g., Google login) is not explicitly visible in the minified background.js.

Monetization

No paid features detected

No evidence of paid features, subscription management, or payment gateways (Stripe, etc.) within the extension code. The extension acts as a client for the Gain destination service. While the destination service likely has paid plans, the extension itself does not gate features or handle billing. The keyword 'pro' found in static analysis was in minified code or unrelated contexts (e.g., Userpilot token, SVG schemas), not indicating extension-gated paid features.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension communicates with gain.ai/app/rpc/ using Bearer token authentication. The background.js code explicitly handles 'Unauthenticated' (code -32001) and 'Forbidden' errors, and implements an 'onUnauthorizedHandler'. It retrieves a token from storage (LOCAL_STORAGE_TOKEN_KEY / gainToken) and attaches it to requests. The extension itself does not implement a login UI but relies on the user being logged into the Gain destination service (gain.ai) to obtain this token. The 'identity' permission in manifest.json suggests integration with browser identity or OAuth flows for the destination service.
