Is Lune a Liner alternative?

For research questions, yes. For general web questions, no. Lune has no open-web index and is not trying to build one.

Does Liner cover academic papers?

Yes, it has an academic mode and a Scholar tier. The difference is depth: Lune reads accepted papers in full so an agent can quote them.

Can I use Lune with a web search tool?

That is the normal setup. Most agents already have web search; Lune adds the peer-reviewed half.

Comparisons

Lune vs Liner

Liner is a general AI search assistant with an academic mode, and a good one. Lune does not search the web at all. It reads peer-reviewed venues in full and hands them to your agent.

Where the difference comes from

The open web is the wrong corpus for a citation

A general assistant has to answer anything, so its index holds the SEO article summarizing the paper, the vendor post repeating the summary, and the forum thread misremembering the number. Ranking sorts that out most of the time. Most of the time is fine for a market question and not for a related-work section.

Lune removes the problem at the index instead. Only top-tier venues go in, so there is nothing to mistake for a source. Ask about a product launch and you get nothing, because it is not there.

What an academic mode does not do

Search over papers gets you the paper. Most academic modes stop there, because their index holds metadata and abstracts.

That is not enough for the work that takes time: quoting the definition an author used, pulling the ablation table, checking whether the claim belongs to the paper you cited or a different one.
