Build a user-defined text filtering pipeline with visual rules. Remove or keep lines in sequential steps, combine AND conditions and OR groups, and inspect every intermediate result locally in your browser.
Paste XML, logs, lists, code, exports, or any other line-based text.
Steps run from top to bottom. A later step sees only the lines left by earlier steps.
Inspect the original text, any intermediate step, or the final result.
User-Defined Regex & Text Filter applies each step to the output of the previous step while keeping Boolean logic explicit: all conditions inside a group use AND and alternative groups use OR. Text stays local in the browser.
Sequentially. Step 2 receives only the lines left by Step 1, Step 3 receives the lines left by Step 2, and so on.
Every condition inside one group must match, which is AND logic. A step matches when any group matches, which is OR logic. This gives an explicit form such as (A AND B) OR (C AND D).
Yes. Choose “Remove lines that match” for the step and set the condition to “Must NOT find” with the desired text.
No. Patterns such as literal text, exact digit counts, URLs, dates and surrounding text are selected visually.
No. The complete filtering pipeline runs locally in your browser.
