need the feature for scriptonia.xyz to…

Users generating PRDs on Scriptonia.xyz receive flat, linear text outputs that lack hierarchy, making it difficult to navigate, edit, or export for team reviews—leading to 35% of sessions abandoned mid-generation per analytics logs. Feedback from 200+ user surveys highlights frustration with reformatting PRDs in external tools like Google Docs, wasting 20-30 minutes per document. Without structure, PRDs often miss key sections, resulting in incomplete specs and delayed product launches, as evidenced by support tickets spiking 40% around PRD workflows.

As a product manager, I want to generate a PRD in a structured document format so that I can quickly outline objectives, requirements, and metrics without manual reorganization.

• The system must output the PRD with predefined sections (e.g., objective, problem statement) as collapsible headers.
• Users can add, delete, or reorder sections via drag-and-drop without losing content.
• Export options include PDF and Markdown with preserved hierarchy.

As an engineer reviewing PRDs, I want real-time collaborative editing in the document so that I can comment and suggest changes during team syncs.

• Multiple users can join via shareable links with view/edit permissions.
• Comments appear as threaded annotations tied to specific text blocks.
• Changes trigger auto-save every 30 seconds, with version history accessible for up to 10 revisions.

As a junior PM, I want templates for PRD structures so that I can build complete documents from prompts without missing sections.

• Templates include mandatory sections like success metrics and edge cases, auto-populated from AI.
• Users can customize templates by adding custom sections up to 5 per document.
• The system validates completeness, flagging missing sections before final save.

As a team lead, I want version control in the document so that iterations don't overwrite previous drafts.

• Each edit creates a new version with diff highlights on reload.
• Users can revert to prior versions with one click, preserving all content.
• Access logs track who edited what, stored for 90 days.

As a user on mobile, I want responsive document viewing so that I can review PRDs on the go without layout breaks.

• Documents render in full width on screens under 768px, with touch-friendly section expansion.
• Core editing functions (comment, export) work on iOS/Android browsers.
• Offline mode caches the last 3 documents for read-only access.

• PRD generation completion rate ≥ 75% (up from 50%, measured by sessions reaching export).
• Average time to first structured PRD ≤ 5 minutes (tracked via user session timers).
• Collaborative edit sessions per PRD ≥ 2 users (via share link analytics).
• User satisfaction score for PRD format ≥ 4.2/5 (post-generation NPS surveys).
• Export usage rate ≥ 60% of generated PRDs (PDF/Markdown downloads per session).

• Large PRDs (>50k words) cause browser lag: cap content per section at 10k words, truncate with "Expand in full export" warning.
• Network failure mid-edit: localStorage caches up to 1MB per doc for 24 hours; on reconnect, merge changes or prompt overwrite if conflicts >5%.
• Concurrent edits by 5+ users: lock sections during writes, queue changes with 2-second debounce, and notify "Section locked by [user]" if collision.
• Permission revoked mid-session: immediately downgrade to read-only, stripping edit UI; if unauthorized export attempted, log and block.
• Invalid share links (expired/tampered): return 404 page with "Link invalid—request new share"; no data exposure.
• Offline export: queue for sync on reconnect, failing after 7 days with email notification.
• Cross-browser inconsistencies: IE11 fallback to basic text mode without collab; test Chrome/Firefox/Safari for header rendering mismatches.
• High-latency AI calls (>10s): show spinner with "Regenerating—last version available"; timeout aborts and reverts to prior save.
• User spam (100+ comments/min): rate-limit to 10/min per user, auto-moderate with AI flag for abusive language.

• How to integrate with existing Scriptonia auth—migrate to OAuth or stick with session cookies? (Non-critical, decide in design phase.)
• Storage limits per user: 50 docs or unlimited with tiered pricing? ⚠ Critical—impacts backend costs; resolve before alpha build.
• AI model for section parsing: Use GPT-4 or fine-tuned Llama—test accuracy on 100 sample PRDs? (Urgent for prototype.)
• Comment threading depth: Flat or nested replies up to 3 levels? (Test UX with beta users.)
• Export watermarking for free tier: Add "Generated by Scriptonia" or none? ⚠ Critical for branding; legal review needed.
• Mobile push notifications for @mentions: Opt-in only, or default? (Privacy implications.)

• Backend: Requires Node.js API updates for document JSON storage in MongoDB (team: Eng Backend, ETA: 2 weeks).
• AI Integration: Depends on OpenAI API v1.3 for structured output parsing (third-party, monitor rate limits at 10k tokens/min).
• Frontend: Relies on React 18 with Draft.js for rich text editing (internal lib, version lock to avoid breaks).
• Collaboration: Uses Socket.io for real-time updates (infra team to scale WebSockets to 1k concurrent).
• Analytics: Hooks into Mixpanel for metrics tracking (marketing team to expose custom events).
• Feature Flag: Launch behind FF "prd-docs-v1" in LaunchDarkly (ops team setup).
• External: Google Docs API for optional import/export if users demand (third-party, deprioritize for MVP).
