Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Project management tool users need to exclude items by criteria on boards (e.g., 'show all tasks except 'blocked' status'). No search volume provided; the support request exists across Jira, Trello, and Linear user communities, indicating recurring friction.
Competition & the opening
Jira (JQL NOT operators), Linear (is not filters), Trello (Butler exclusion logic), Productboard (advanced negation filters), Kanboard (tag:not: syntax), and BetterBoard all support negation. The gap: no board filter UI unifies negation across multiple criteria (e.g., NOT status=blocked AND NOT assignee=Alice) with one-click sharing or saved presets that persist across team views.
What's hard to build
Most project tools use proprietary query languages or closed filter builders; extending them requires deep codebase changes or marketplace plugin SDKs with limited API surface. Building a cross-tool negation layer that works on Jira, Linear, and Asana simultaneously requires reverse-engineering each product's filter model.
Why now
Jira and Linear already have negation filters built-in; this request is for a non-Atlassian/non-Linear board tool (likely Trello or Kanboard), where negation filtering is underdeveloped.
How you'd monetize
$4–8/mo per board or freemium (native plugin, low-friction monetization)
