Compare two lists
in seconds
Paste or drop two lists — usernames, emails, IDs, anything. Instagram exports work as-is, .html or .json, no cleanup. See what's only in A, only in B, and in both.

Free — no signup, no row limits.
Built for real-world list checks
- →Followers vs following. Drop your Instagram or TikTok export files and find who doesn't follow you back — or who you don't follow back.
- →Email list overlap. Compare two exports before sending — find shared addresses and net-new leads.
- →Allowlist / membership checks. Compare an updated list against yesterday's snapshot to spot additions and removals.
- →Any two lists of identifiers. Usernames, order IDs, SKUs, domains — one value per line is all you need.
We auto-handle common exports
Drop the file straight from the platform — no cleanup needed. We detect the shape and extract the handles automatically.
