List lines that appear in both multiline texts. Processing runs in your browser—Toolcore does not need your paste for the core operation on this page.

Deterministic string metrics only; rephrased text may score differently than human judgment.

Paste or type in the main field, then read the output below. Use Load example when available, or open the page with ?q= / ?qb= so tickets and agents share the same input.
