Save the reels worth remembering. You scroll. You save. You forget. By the time you want that pasta recipe, that ab workout, or those Lisbon travel tips, the reel is buried somewhere in a folder of 400 others, and Instagram's search won't help you find it. Clera fixes this. Share any Instagram reel to Clera and get back a clean, structured summary you can actually use. Recipes turn into ingredient lists and steps. Workouts turn into sets, reps, and form cues. DIY projects turn into materials and instructions. Travel tips turn into organized recommendations. The video gets transformed into something you can search, scan, and refer back to. FREE AND CLERA PLUS Clera is free to download and includes 3 summaries per month. More summaries require Clera Plus, an optional auto-renewing subscription (in-app purchase), available monthly or annually. Full terms are at the end of this description. HOW IT WORKS 1. Find a reel worth saving on Instagram 2. Tap share, select Clera 3. Get notified when your summary is ready (if you allow notifications) 4. Open Clera to find it organized and waiting That's it. No screen recording. No digging through saved folders. WHAT YOU GET IN EVERY SUMMARY Title: A clear name for the saved content Materials or ingredients: Everything you need, in one list Steps: Numbered, sequential, easy to follow Pro tips: The little details creators mention that you'd otherwise forget It's the reel, but readable. WHO CLERA IS FOR Home cooks who save more recipes than they ever make Fitness enthusiasts building their own workout library DIYers planning weekend projects Travelers collecting tips for upcoming trips Anyone who treats Instagram as a knowledge feed instead of just entertainment WHY PEOPLE LOVE IT Most reel-saving apps just bookmark the video. You still have to rewatch it every time you want the information. Clera does the work of watching, listening, and organizing for you, so the next time you want that recipe, you can read it in 10 seconds instead of scrubbing through a 60-second video while your hands are covered in flour. You're not building a video library. You're building a knowledge library. SHARE EXTENSION INTEGRATION Clera works directly from Instagram's share sheet. No switching apps, no copy-pasting links. See a reel you want to keep? One tap and it's on its way to becoming a saved summary. PRIVACY FIRST No account needed for the free plan. You only sign in (with Apple) if you subscribe to Clera Plus, so your subscription stays with you across devices. Clera does not track you across other companies' apps or websites, and we never sell your data. Summaries are made from the links you choose to share, and your saved library stays on your device. WHAT CLERA IS NOT Clera doesn't repost, redistribute, or display the original videos. It doesn't replace Instagram. It's a personal tool for turning the reels you find valuable into notes you can actually use later. GET STARTED Download Clera. Share your first reel. See what your saved feed could be when it's organized for you instead of against you. The reels you actually want to remember deserve better than a folder you'll never open again. CLERA PLUS SUBSCRIPTION TERMS Clera Plus is an optional auto-renewing subscription, available monthly or annually and billed to your Apple ID. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Verdict
The clearest difference is in-app purchases: Clera at none against ChatPDF's 2. Clera also leads on ads (none vs shown). ChatPDF's advantage is update cadence (every 4 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.
