When to switch from Smush
Switch if you also need bulk alt text
Smush has zero alt text generation. CapstonAI generates vision-based alt text for thousands of images in a single batch.
Switch if you need AI citation tracking
Smush is image-only. CapstonAI tracks how often ChatGPT/Perplexity/Gemini/Claude cite you.
Switch if you also run Shopify
Smush is WordPress only. CapstonAI Shopify app handles product images, variant alt text, and store-wide WebP.
Stay on Smush if
You only need basic compression on a small WordPress site, you’re already on the WPMU DEV ecosystem, and you don’t care about AI visibility tracking.
Migration tips from Smush Pro
- Keep Smush installed initially — no rush
- Install CapstonAI alongside (no conflict, both honor existing WebP files)
- Run free CapstonAI scan to map gaps (alt text missing on 70-80% of media library typically)
- Use CapstonAI for what Smush doesn’t do: alt text, meta, AI tracking
- Decide later: keep both or consolidate to CapstonAI
FAQ
Will Smush add AI alt text generation?
As of May 2026, no public roadmap commitment. Smush has stayed focused on compression for over a decade.
Can I use Smush free + CapstonAI?
Yes, that’s a popular combo. Smush handles basic compression. CapstonAI handles WebP/AVIF advanced + alt text + meta + AI tracking.
What’s the real-world page weight savings?
Smush + WebP/AVIF on a typical WordPress site: 25-35% page weight reduction. CapstonAI smart per-image quality on the same site: 32-42% reduction (more aggressive on photos, lossless on logos).
Cloudflare Polish or a plugin?
If you’re already on Cloudflare Pro, Polish covers most needs at edge. Add a plugin only if you also need alt text generation or AI tracking (Polish doesn’t do either).
