Lune vs ScholarAI

ScholarAI was early to putting real papers inside ChatGPT, and its reach shows: a GPT, an API, an MCP server, and drafting in Jenni. Lune covers less of the literature and goes deeper into it.

If the first list is you, take ScholarAI.

Choose ScholarAI if

  • ChatGPT is where you work and you want a GPT that already searches papers.
  • You want drafting and auto-citation in the same product, with Zotero sync.
  • Your topic spans clinical or life-science journals.

Choose Lune if

  • You move between clients and want one connection that behaves the same.
  • You need the exact sentence and its locator, not a link.
  • You compare methods across papers and want one typed table.
  • You want reviewer expectations in the same connection as the papers.

Where the difference comes from

Collecting sources, or checking sentences

ScholarAI is good at the first. Ask in ChatGPT, get real papers, save them, sync to Zotero, let Jenni drop them into the draft. That is a short path from question to bibliography.

Lune is built for what happens after the draft exists. verify_claims answers each sentence with the quote that supports it, or with nothing at all. The point is not a faster bibliography. It is that reference 14 says what you said it says.

One connection that outlives your client

ScholarAI reaches most people where they already are, and has done for longer than most. Its writing path runs through Jenni, so the further you get from ChatGPT and Jenni, the more of the product you leave behind.

Lune connects one way, through the protocol. The same tools answer in Claude Code, Cursor, Codex and ChatGPT, with the same scopes and quota. Switch editors and nothing about your setup changes.

What your agent can call

  • search_papers
  • search_papers_many
  • search_related_papers
  • get_paper_fulltext
  • get_paper_citations
  • extract_from_papers
  • verify_claims

  • get_research_guidance_doc

One connection, in Claude Code, Cursor, Codex, ChatGPT or anything else that speaks MCP. The same tools back the miniapps in the Lune dashboard.
