Apple Notes accepts links through the share sheet and shows a small preview. It is free, already there and synced through iCloud. Trouble shows up at scale, as links get buried among notes, and you get little help finding one by what the page said.
Bear is a lovely Markdown writing app for Apple devices with tags and links between notes. It handles links as text within your writing. That suits a research note, but it is not a bookmark manager.
Nemos treats a link as an item. It arrives with a preview, including from Instagram and TikTok. Articles stay offline, read-aloud plays them, a reminder can bring one back, and search covers links with screenshots, notes and transcripts. The cost is that it is one more app, and it is not a writing tool.
A simple rule: under a few dozen links a year, Apple Notes is enough. If you save links daily, use something built for it. If you write more than you save, take Bear.
