OnPlan

OnPlan turns scattered team opinions into a structured product requirements document. Instead of asking one person to write the spec, it interviews stakeholders across roles — CEO, engineers, designers, sales — and then synthesizes their answers into an organized eight-section PRD. The interview format draws out each perspective, so decisions, constraints, and priorities that usually live in separate heads end up captured in one place. Because OnPlan compiles the document itself, teams can produce a complete PRD without a dedicated product manager driving the process, which is useful for early-stage startups and small teams. The output follows a consistent eight-section structure, giving every project the same shape and making documents easier to compare and review. Results depend on how candid and detailed the team's input is, and the fixed format may need adjusting to fit an existing template, so a human pass before development starts is still worthwhile.

Product teams use OnPlan to interview stakeholders and compile their input into a structured eight-section PRD without a dedicated product manager.
