Task 15 Implementation Summary

Changes Made

1. Removed Premium Restrictions from AI Summary Features

Files Modified: extension/popup/popup.js

• Domain Summary (executeAISummary function): Removed premium check that was blocking free users from using domain summary functionality
• Site Content Summary (executeSiteContentSummary function): Removed premium check that was blocking free users from using site content summary functionality

Before:

// Check if user has premium subscription (AI Summary is premium-only)
if (!this.premiumStatus || !this.premiumStatus.isPremium) {
  Utils.showToast('AI Summary is a premium feature. Upgrade to premium to summarize your notes by domain.', 'info');
  return;
}

After:

// AI Summary is now available to all users (free and premium)
// No premium check needed

2. Updated Site Summary Usage Display

Files Modified:

• extension/popup/popup.js (loadSummaryUsageInfo function)
• extension/popup/popup.html

Changes:

• Modified usage display to show “Site Summary Uses” instead of raw tokens
• Each site summary costs 20 tokens, so display shows Math.floor(remainingCalls / 20) uses
• Updated HTML to show “Site Summary Uses: X/Y per month” format
• Free users: 5 tokens = 0 site summary uses (since 5 < 20)
• Premium users: 500 tokens = 25 site summary uses (500 / 20 = 25)

Before:

usageCount.textContent = usageData.remainingCalls || 0;
usageLimit.textContent = usageData.monthlyLimit || 500;

After:

const remainingSiteSummaryUses = Math.floor((usageData.remainingCalls || 0) / 20);
usageCount.textContent = remainingSiteSummaryUses;

const totalSiteSummaryUses = Math.floor((usageData.monthlyLimit || 500) / 20);
usageLimit.textContent = totalSiteSummaryUses;

3. Added Usage Validation

Files Modified: extension/popup/popup.js

• Site Content Summary: Added validation to ensure users have at least 20 tokens before allowing site content summary
• Domain Summary: Added validation to ensure users have enough tokens for the number of notes being summarized (1 token per note)

Site Content Summary Validation:

const currentUsage = await this.getCurrentAIUsage();
if (!currentUsage || currentUsage.remainingCalls < 20) {
  const remainingUses = Math.floor((currentUsage?.remainingCalls || 0) / 20);
  Utils.showToast(`Not enough tokens for site summary. You have ${remainingUses} site summary uses remaining. Each site summary requires 20 tokens.`, 'warning');
  return;
}

Domain Summary Validation:

const currentUsage = await this.getCurrentAIUsage();
if (!currentUsage || currentUsage.remainingCalls < domainNotes.length) {
  Utils.showToast(`Not enough tokens for domain summary. You need ${domainNotes.length} tokens but only have ${currentUsage?.remainingCalls || 0} remaining.`, 'warning');
  return;
}

Impact on User Experience

Free Users (5 tokens/month)

• Domain Summary: Can summarize up to 5 notes total per month (1 token per note)
• Site Content Summary: Cannot use (requires 20 tokens, but only have 5)
• AI Rewrite: Can use 5 times per month (1 token per rewrite)

Premium Users (500 tokens/month)

• Domain Summary: Can summarize up to 500 notes total per month (1 token per note)
• Site Content Summary: Can use 25 times per month (20 tokens per use)
• AI Rewrite: Can use 500 times per month (1 token per rewrite)
• Mixed Usage: Can combine features (e.g., 10 rewrites + 1 site summary + 470 domain notes)

Supabase Functions

No changes required - The existing ai-rewrite edge function already handles variable token consumption correctly:

• Receives increment amount from extension
• Processes usage tracking with correct amounts
• Returns updated usage information

Testing Recommendations

1. Test with free user account:
   • Verify domain summary works with small number of notes
   • Verify site content summary shows appropriate error message
   • Verify usage display shows correct “uses” format
2. Test with premium user account:
   • Verify both features work without restrictions
   • Verify usage display shows correct calculations
   • Verify token consumption is accurate
3. Test edge cases:
   • User with exactly 20 tokens trying site summary
   • User with fewer tokens than notes trying domain summary
   • Usage display updates after consuming tokens
