FeedScholar vs R Discovery
R Discovery (by Cactus Communications) is a popular research app with reading feeds, audio summaries, and translations. The core difference is philosophy: R Discovery wants to be an app you open; FeedScholar wants to disappear into the one tool you already check: email.
In fairness: R Discovery's app is polished and feature-rich, with millions of registered users, audio paper summaries, and multi-language support.
| R Discovery | FeedScholar | |
|---|---|---|
| Format | Mobile app you check | Email digest that arrives, no new habit |
| Matching | Interest topics + ML feed | An exact-subfield profile with written reasons |
| Learning | In-app engagement signals | On paid plans, one-click from the email itself |
| Price | Freemium; Prime roughly $12–25/mo (as of mid-2026) | Free monthly digest of the top 5 papers; weekly or monthly with Basic $7/mo, Pro $15/mo |
The honest verdict
If you enjoy a reading app with bells and whistles, R Discovery is worth a look. If your inbox is where work happens and you want relevance density over features, FeedScholar sends you less, on purpose.
