AI Evaluation Details (Score: 8.2/10)
The output successfully delivers warm, community-focused messaging with excellent structure and practical components. However, both captions exceed the 150-word limit (approximately 155-160 words each), and the density of logistics in the middle paragraphs creates readability challenges that contradict the prompt's emphasis on scannable, mobile-first formatting.
- • Strong, benefit-focused hooks that avoid the generic 'Join us' opening—both versions lead with safety/curiosity
- • Essential details (What/When/Where/Cost) are correctly front-loaded in lines 1-2 before the 'See more' fold
- • Warm, accessible tone throughout that feels genuinely community-oriented rather than institutional
- • Excellent pinned comment that adds logistical value (agenda timeline, parking specifics, what to bring)
- • Image suggestion is realistic for a small volunteer team and includes thoughtful, descriptive alt-text
- • Proper restraint with emojis (1 only) and hashtags (2 relevant ones)
- • All required tags included correctly, and CTA is clear with dual action ('RSVP' + 'Tap Interested or Going')
- • Posting tips are practical and include a smart event-day reminder strategy
- • Word count violation: both captions run 155-160 words instead of the required 100-150 maximum
- • Middle section becomes a wall of text with accessibility, childcare, parking, and COVID details stacked in two dense paragraphs—contradicts 'short, scannable sentences and line breaks' requirement
- • The 'bring a 16oz water sample' instruction appears at the very end after the CTA, but this is critical prep information that should be more prominent or in the pinned comment only
- • Minor redundancy: 'Free kits while supplies last' repeats the 'first 50 households' urgency already stated earlier
- • The A/B test variation changes only two words in the hook ('Keep your family's drinking water safe' vs. 'What's in your well water?'), which may not provide sufficiently distinct testing data

AI Evaluation Details (Score: 8.2/10)
The output demonstrates strong adherence to the prompt template with appropriate formal tone and comprehensive structure. However, it exceeds the 150-word limit (approximately 165 words in each caption) and the spokesperson sign-off feels slightly forced in a Facebook context, reducing authenticity.
- • Excellent front-loading of critical information (What/When/Where/Cost) in first two lines before 'See more' cut-off
- • Strong, benefit-driven hooks that avoid the clichéd 'Join us' opening
- • Proper UTM parameter integration and partner tagging as requested
- • Comprehensive accessibility details woven naturally into the copy
- • Well-crafted pinned comment with practical logistics and clear contact information
- • Appropriate formal tone throughout without being stiff or overly corporate
- • Effective A/B test variation that isolates only the hook for clean testing
- • Image suggestion is realistic and includes proper alt-text for accessibility
- • Posting tips include platform-specific best practices (square image, alt text, timing)
- • Word count exceeds the specified 100-150 word limit (approximately 165 words), which could reduce engagement
- • The formal sign-off '– Jenna Park, Program Director' feels unnatural for Facebook; this format works better in email or LinkedIn
- • Minor redundancy: 'Ideal for new and intermediate grant writers at small organizations' restates the target audience already mentioned
- • Could benefit from one strategic line break between the speaker details and the 'Leave with' sentence for better scannability

AI Evaluation Details (Score: 8.4/10)
This is a strong, professional output that follows the template closely and delivers practical, ready-to-use content. The warm tone is appropriate for a family event, essential details appear before the fold, and the A/B test variation provides genuine value. Minor weaknesses include slight repetition and a word count that pushes the upper limit, but overall this would serve a nonprofit communications team well.
- • Excellent adherence to mobile-first structure with What/When/Where/Cost in lines 1-2 before 'See more'
- • Both hooks are benefit-focused and emotionally resonant ('Make a memory' vs. 'splash of color and calm') rather than generic 'Join us' language
- • Comprehensive logistics integration without overwhelming the reader—accessibility, transit, and safety details are woven naturally
- • A/B test variation genuinely differs in emotional appeal (memory-making vs. sensory experience) while keeping structure identical for valid testing
- • Pinned comment effectively offloads detailed agenda and contact info, keeping main caption scannable
- • Image suggestion is specific, achievable for small teams, and includes thoughtful alt-text with accessibility signage detail
- • Posting tips go beyond generic advice with actionable items like adding the RSVP button and updating pinned comment day-of
- • Ethical urgency is honest and specific ('first 200 kids') rather than manufactured scarcity
- • Minimal emoji use (1 per caption) adds warmth without appearing unprofessional
- • Word count is 147-148 words, at the very top of the 100-150 range, which could feel dense on mobile; trimming 10-15 words would improve scannability
- • The phrase 'RSVP required; art kits limited to first 200 kids' appears twice in each caption (once in body, once at end), creating unnecessary repetition
- • The spokesperson sign-off (Alicia Moreno) was requested but not included in either caption, missing a personalization opportunity
- • Hashtag strategy is minimal (#HarborCityArts #FamilyDay)—could benefit from one more relevant tag like #HarborCityFamilies or #MuseumDay for discoverability
- • The sensory-friendly hour detail could be more prominent given its importance to neurodiverse families—currently buried mid-paragraph
