Nucel is one library with a few tools on top. Here is what each one does, what it reads, and where it stops.

Core features

  1. Share from the Android app, paste a link on the web, or import an archive. Forwarding an email is aStandard+ feature, and so are webhook saves.

  2. Keyword and meaning search run together, so a half-remembered phrase still finds the save. Results come only from your own library, closest matches first.

  3. Ask answers only from what you saved, with citations that open each source. Compare sets two or more saves side by side, showing where they agree and where they pull apart.

    Deep answers Pro use a more capable model for questions that need careful reasoning across many saves.

Mind shows what your library is about

Topics group your saves, and related topics sit under one theme. Memory notes, clusters, gaps and a timeline come with Standard+.

Review turns saves into flashcards

Nucel can make flashcards from saves and bring them back on a spaced schedule, so what you saved gets remembered instead of only stored. Flashcards are a Standard+ feature.

Resurfaced saves and a weekly digest

Saves you have not opened in a while come back on home, so the pile gets a second look. A weekly digest gathers what you saved and what has been resurfacing.

Pro can switch the digest to daily. Pro

Collections keep a set together

Group saves into a collection, give it a cover, and share it with a public link. Ask can answer about a whole collection, not only one save.

Automations act on new saves

A rule runs on each new save that matches it, such as tagging it and then starring it. Free includes 2 automations, Standard 10 and Pro 25. Extra ones are kept but paused, never deleted.

Sample library · Example rule

  1. WhenA save has the topic pricing
  2. ThenAdd the tag pricing-research, then star it

Bring the saves you already have

Import an archive of X bookmarks, Reddit saved posts or Instagram saved posts, and Nucel reads them in the background. Free includes one import of up to 500 items. Standard allows 3 a month, up to 2000 items each, and Pro has no import count limit, up to 5000 items each.

Sample library · Archive sources

  • Twitter / X
  • Reddit
  • Instagram

Bulk import covers these three exports only.

Focus reader

Focus opens a saved article as a plain page with its summary and topics beside it. Only text-bearing saves have a readable body; a video shows its title and channel.
