RedeemCode Striker – Auto-cross out used codes in community posts

Automatically mark used redeem codes in forum threads so sharers and claimers see what's left

Problem

In communities like V2EX, users often post a batch of redeem codes, and others reply 'used'. But in a long thread, it's hard to tell which codes are still available, leading to wasted attempts and frustration. Manual checking is tedious and error-prone.

Solution

A browser extension or lightweight web service that parses redeem codes and replies in a post, automatically identifies which codes have been claimed, and strikes them through or marks them as used. Supports mainstream community platforms and can integrate with existing enhancers like V2EX Polish.

Users

Users who share or claim redeem codes in forums and communities, as well as moderators wanting to improve community experience.

MVP

Extract redeem code patterns from page; parse replies for keywords like 'used' or 'claimed'; dynamically strike through used codes on the frontend; provide a simple toggle; support 1-2 major communities like V2EX.

Revenue

Freemium: basic free; premium offers batch management, custom rules, and multi-community support for $2-5/month or donations.

Why now

Redeem code sharing is frequent in communities, but existing tools don't solve this niche pain. An indie developer can quickly build a browser extension with low technical barrier and clear user demand.
