Sehn was a personal search and curation product developed by Sehn Inc., designed to help people organize and rediscover content they saved, liked, or created across the web. The service acted as a digital-footprint aggregator, syncing content from connected platforms and indexing it for semantic search. Its AI features tagged items and linked related material, helping users explore connections across their saved content.

Sehn also supported curated lists: users could assemble and share collections, subscribe to lists from other curators, and search content saved and vetted by other people. Autogenerated memories and highlights were intended to help users retain and revisit useful or interesting material. The product’s stated goal was to give individuals more control over fragmented online content and make discovery more personal, with curation positioned as a way to find worthwhile articles, insights, places, and products amid online noise.

Sehn described its service as an evolving cross-platform experience. However, Sehn was sunset as a product in January 2023, so these features describe its offering before discontinuation
