Many workflows, one API.

Manuscript review, scientific figures, and evidence synthesis, all with one key. Pick a product to see what its requests and responses look like. Everything here is also available as an MCP tool.

What you can do

The same engine as the Nubint app. Check manuscripts, draw figures, and gather evidence from the literature. Every verdict comes with its basis, and anything we could not confirm is reported as unconfirmed.

Reference verification

Checks each reference against the OpenAlex and KCI scholarly indexes to confirm the work exists, and returns its bibliographic data as CSL-JSON.

AI writing detection

Judges paragraph by paragraph and points to the sentence that drove the flag.

Full manuscript check

Adds source quality (retractions, preprints, rarely cited sources) to the two checks above and returns results per section.

Scientific figures and charts

Draws illustrations and flowcharts from a description, and plots tables as charts by code, with exact values. Exports to SVG and PPTX.

Evidence synthesis

Searches papers and writes cited literature reviews. Systematic review and data extraction are coming soon.

MCP tools

The same features, called in plain words inside ChatGPT and Claude. Connect with a sign-in, no API key.

Quickstart

Your first request in three steps

  1. 1

    Get an API key

    Create one in the Nubint app under Settings → API/MCP. The key is shown only once, so store it right away.

  2. 2

    Send a request

    Put the key in the X-API-Key header and send your reference list. The example works as-is.

  3. 3

    Read the result

    Only items whose status isn't verified need a look. summary.needsReview tells you how many.

Want it in ChatGPT or Claude?

No code needed. Connect Nubint to ChatGPT or Claude and the same checks — plus manuscript review, literature work and figure tools — are available mid-chat with just a sign-in, no API key.

Connect via MCP

FAQ

Get a key and send your first request

The API and MCP are available from the Starter plan, and tools that use no credits, such as paper search and reading documents, deduct nothing. One key works for both the API and MCP.
