StashSync is an offline-first workspace that brings your notes, bookmarks, and files together — so nothing gets lost across scattered apps. Write rich notes with a full editor (tables, code blocks, math, embeds), save bookmarks with auto-fetched previews, and store files up to 100 MB. Everything syncs instantly across devices using CRDT — no conflicts, no waiting, no internet required. Free to start. Pro at $3.99/mo.
