LinkWise is an AI bookmark manager built for one job: helping you find links again. Most bookmark tools are great at saving. The hard part is retrieval — when your folders turn into a graveyard of “read later” pages you will never open. LinkWise turns every URL into a searchable bookmark with an AI summary and keyword tags you confirm, then lets you browse by keywords or ask in plain English. How it works 1. Paste any URL on https://linkwise.link (no signup required to try the extractor). 2. Get title, description, AI summary, and keyword suggestions in seconds. 3. Save to your personal library, confirm or edit tags, and organize into collections. 4. Find links later with keyword filters — or Pro semantic search (“that pricing article from last month”). Key features • AI summary and keyword suggestions on save • Keyword search and filters across your library • Nested collections / folders • One-click browser save: Chrome, Edge, and Firefox extensions • Bulk import from browser bookm

AI Image Expander is a free online outpaint tool built for the moment a photo is almost right—but the platform wants a different frame. Creators shoot square or landscape, then need 9:16 Stories and Reels, 1:1 feed posts, 16:9 covers, or other catalog ratios. Stretching pixels looks cheap; hard crops cut faces and products. AI Image Expander grows a new canvas around the original and fills empty borders with AI-generated context so the subject stays intact.How it works: users upload a single JPG, PNG, or WEBP photo, pick an aspect ratio (1:1, 2:3, 3:2, 16:9, 9:16, 3:4, or 4:3), and choose scale—Auto or fixed multipliers such as 1.2×, 1.5×, or 2×. A live preview shows the final canvas size before spending a free expand. The pipeline keeps the original image centered and outpaints only the borders required by the target layout. When done, users download a watermark-free result. Signing in with Google unlocks expand history for later re-downloads and a higher free daily quota.Supported inputs typically allow up to 10 MB per file, with shortest side at least 256px and longest side at most 4096px. A 25MP canvas safety limit blocks scale choices that would produce an oversized result. Guests receive a limited number of free expands per day; signed-in users get more. Abuse controls such as captcha, rate limits, and file validation help keep the free tier available. Uploads are processed to fulfill expand requests and are not used to train public AI models; retention details live on the Privacy Policy page.Pricing for the core experience is free. Daily quotas protect capacity; future paid features may appear later, but ordinary free expands do not require checkout today. The product runs in modern browsers on desktop and mobile—no installer and no offline generation mode. An internet connection is required for each job.Responsible use is part of the product story. Outpainting may leave soft seams, blur, or invented background detail—especially near people, text, or logos at the edge. Results are creative assistance, not a guarantee of perfect photoreal borders. AI Image Expander is therefore positioned as a practical social and commerce helper for creators, shop owners, travel posters, and listing editors—best paired with a quick visual review before publishing.In short, AI Image Expander packages generative outpainting into a reliable free web tool: social aspect presets, Auto or fixed scale, canvas preview, free daily quotas, optional history after sign-in, and watermark-free downloads for anyone who needs Story and Reel frames without reshooting.
