How does deduplication work?

Three layers: URL matching (exact post URL tracking), content hashing (fingerprinting post content to catch reposts), and user-level history (your personal seen-post database that persists indefinitely).

What if a post is edited after I've seen it?

URL matching will still catch it since the post URL doesn't change. Only entirely new posts from different authors will appear in your feed.

Can I reset my dedup history?

Currently, dedup history is permanent to maintain feed quality. If you need to revisit old posts, you can search for them directly on Reddit.

Deduplication

Reddix remembers every post you've already seen. Our deduplication engine uses URL matching and content hashing to ensure your lead feed stays clean, fresh, and free of repeats.

A clean feed, every time

Every scan checks discovered posts against your history using URL matching and content fingerprinting. Crossposted, edited, or reposted content is caught and filtered — so your lead feed only shows genuinely new opportunities.

Key benefits

URL-based matching — Every Reddit post URL is tracked per user. If you've seen it before, it won't appear again — regardless of which scan found it.
Content fingerprinting — Content hashing catches crossposts, reposts, and slightly edited duplicates that share the same core content.
Permanent history — Your seen-post history is stored indefinitely. Even if you scan the same subreddits months later, old posts stay filtered.
Cleaner analytics — Deduplication means your lead counts and scoring stats reflect genuinely unique opportunities — no inflated numbers.

Who it's for

Daily Scanner: Runs scans daily across 10 subreddits. Without dedup, 30%+ of leads would be repeats from yesterday. Outcome: Every morning's leads are fresh and actionable — zero time wasted on repeats.
Multi-Keyword User: Monitors 15 keywords that often match the same Reddit posts. Dedup ensures each post appears only once. Outcome: Lead count reflects unique opportunities, not keyword overlap.
Long-Term User: Has been using Reddix for 6 months. Dedup history means ancient posts never resurface. Outcome: Lead quality stays consistently high over months of use.
