Reader is broader

Readwise Reader is built to hold many reading formats in one place. Its documentation covers highlighting, tags, notes, document organization, and reading workflows across a much wider corpus than X.

Talon goes deeper on X

Talon distinguishes bookmarks from likes, synchronizes folders where available, keeps thread and author context, and builds a review and retrieval flow around social saves.

You may use both

A reading system and an X research library solve adjacent jobs. The deciding question is whether tweets are one input among many or the material you return to most often.

Questions

Does Readwise Reader support tweets?

Its documentation lists tweets among the supported content types.

Does Talon replace Readwise highlights?

No. Talon supports notes and highlights, but its differentiated job is X-native retrieval and cited answers.
