Is Lune an R Discovery alternative?

Only partly. R Discovery is a reading app; Lune is retrieval and verification for agents. Many people would use both.

Does R Discovery work with AI agents?

It publishes a ChatGPT integration and a Chrome extension. No MCP server is listed on their site.

Does Lune have a mobile app?

No. Lune runs inside the AI apps you already use, and its dashboard works in a phone browser.

Lune vs R Discovery

R Discovery is built for reading. It follows your interests across the published record, reads papers aloud, translates them, and does it well on a phone. Lune is not a reading app.

Where the difference comes from

These two barely compete

R Discovery answers the Monday morning question: what came out that I should read? It does that across an enormous span of work, and its translation and audio solve a real problem for people who do not read English all day.

Lune answers the Thursday night one: is this sentence supported, and by which line of which paper? One is a reading habit. The other runs while you write. Using both is sensible.

Feeds hand you papers, agents need passages

A recommendation works at the level of the paper. That is the right unit for reading and the wrong one for an agent, which needs the paragraph holding the number.

So Lune indexes accepted papers in full and exposes search, sweep, full text, the citation graph, typed extraction and claim checking. Chain those and you arrive at a quote. A feed was never trying to.
