Assist with core product management activities including writing product requirements documents (PRDs), analyzing feature requests, synthesizing user research, planning roadmaps, and communicating product decisions to stakeholders and engineering teams.
Unlike point-solution PM tools:
A good PRD should include:
Use structured frameworks to evaluate features:
When synthesizing research:
Effective roadmaps should:
Depending on the task, generate:
# PRD: Advanced Search Functionality
## Problem Statement
Users frequently report difficulty finding specific items in our catalog when they have multiple criteria (price range, location, category, features). Our current search only supports simple text queries, leading to:
- High bounce rates on search results pages (65% bounce rate vs 32% site average)
- Increased support tickets asking for search help (150/month)
- Lost conversion opportunities (estimated $500K annual revenue impact)
## Goals and Success Metrics
**Primary Goal**: Enable users to find relevant items quickly using multiple filters.
**Success Metrics**:
- Reduce search result page bounce rate from 65% to <40%
- Increase search-to-purchase conversion rate by 25%
- Reduce search-related support tickets by 50%
- 70% of users engage with at least one filter within 30 days
## User Stories
### Must Have
1. As a buyer, I want to filter by price range so I can find items within my budget
2. As a buyer, I want to filter by location so I can find items near me
3. As a buyer, I want to filter by category so I can narrow down item types
4. As a buyer, I want to combine multiple filters so I can find exactly what I need
5. As a buyer, I want to see filter counts so I know how many items match before applying
### Should Have
6. As a buyer, I want to save my filter preferences so I don't have to reapply them
7. As a buyer, I want to see suggested filters based on my search query
8. As a buyer, I want to sort filtered results by relevance, price, or date
### Nice to Have
9. As a buyer, I want to create saved searches that notify me of new matches
10. As a buyer, I want to share a filtered search URL with others
# Feature Analysis: Dark Mode Support
## Request Summary
**Source**: User feedback (150+ requests in past 6 months), competitive pressure
**Description**: Add dark mode theme option to web and mobile apps
## User Need
Users working in low-light environments report eye strain with current light-only theme. Power users (25% of DAU) spend 3+ hours/day in app and strongly prefer dark mode.
## Prioritization Score
Using RICE framework:
- **Reach**: 750K users = 750
- **Impact**: 8/10 (high for target segment) = 0.8
- **Confidence**: 85% = 0.85
- **Effort**: 7 weeks = 7
**RICE Score**: (750 × 0.8 × 0.85) / 7 = **73.2**
## Recommendation
**Proceed with Option 1 (Full Dark Mode)**
**Reasoning**:
- High impact for large user segment (45% of base)
- Strong user demand and competitive pressure
- Effort is reasonable relative to value
- RICE score above our threshold (>50)
- Aligns with product, technical, and business strategy
Comprehensive specification of what to build and why. Include problem statement, goals, user stories, requirements, technical considerations, risks, and launch plan.
Lighter-weight than PRD; quick summary of a feature idea with key details. Use for early-stage exploration before committing to full PRD.
Summary of user research findings (interviews, surveys, usability tests) with patterns, insights, and recommendations.
Strategic plan of what to build over time. Organize by themes and time horizons; focus on outcomes not just outputs.
Record of important product decisions, the options considered, the decision made, and the reasoning. Critical for institutional memory.
Detailed plan for rolling out a feature including phases, feature flags, metrics, monitoring, and rollback procedures.
Comparison of competitors' features, approaches, and positioning. Inform product strategy and feature prioritization.
Executive summary of a product initiative. Use to communicate to leadership and get alignment.

Cloud laboratory platform for automated protein testing and validation. Use when designing proteins and needing experimental validation including binding assays, expression testing, thermostability measurements, enzyme activity assays, or protein sequence optimization. Also use for submitting experiments via API, tracking experiment status, downloading results, optimizing protein sequences for better expression using computational tools (NetSolP, SoluProt, SolubleMPNN, ESM), or managing protein design workflows with wet-lab validation.
