The landscape lists 20 tools. This session maps all of them across the research pipeline steps that matter — database search, screening, extraction — and tells you which ones to reach for on a health financing brief.
The right question is not "which tool?" but "which job?"
The 20 tools in the catalogue are not interchangeable. They differ on two dimensions that matter most for health economics and financing work: what corpus they search, and what they do with what they find. Choosing the wrong tool for a job does not just slow you down — it silently shapes what evidence you see and what you miss.
Think of the tools in two categories: retrievers find and surface papers; synthesisers read and summarise them. Some tools do both. Most do one well. The distinction matters because your bottleneck — as you identified in Session 1 — determines which category you need first.

A map of the tool landscape
For health economics and financing work, the most useful way to organise the tools is by two questions: does it search grey literature, and does it handle dense PDFs (government reports, HTA assessments, budget documents) rather than just journal abstracts?
Good for mapping a field or finding seminal papers. Miss NSSO reports, HTAIn briefs, state NHA accounts, MoHFW working papers entirely.
Best for WHO India work
Elicit · Research Rabbit + manual grey search · Claude / GPT with uploaded PDFs
Elicit excels at structured data extraction from papers. For grey literature, there is no substitute for targeted manual search — but Claude or GPT can then process what you retrieve.
Synthesiser
Fast summaries, limited scope
Consensus · Paper Digest · SciSpace
Useful for quick orientation in a new topic. Will confidently summarise the published literature while being unaware that the most relevant evidence is in a 2023 HTAIn report sitting outside their index.
Workhorse for long documents
Humata · Claude (with PDF upload) · NotebookLM
Upload a 200-page NSSO survey, a PM-JAY evaluation, or a stack of state health accounts and interrogate them directly. This is where the grey literature gap from Session 1 gets closed.
The five tools worth knowing in depth
For a WHO India health financing context, five tools do most of the work. Click each card for an honest assessment — including what it cannot do.
What every AI tool in this space cannot see
There are four blind spots shared by virtually all AI literature tools. Knowing them is not pessimism — it is workflow design. Each has a practical workaround.
🗂️
Grey literature and government data
NSSO surveys, HTAIn assessments, MoHFW circulars, state health accounts, NHA reports, district-level HMIS data. None of it is in any tool's default index.
→ Manual targeted search + upload to Claude/Humata for interrogation
🌍
LMIC-specific financing evidence
Indexed literature skews toward high-income country health systems. A search for "community health insurance equity" surfaces the Netherlands before Kerala.
→ Explicit geographic filters in every search; use Dimensions.ai for LMIC filtering
📅
Very recent publications
AI tools have indexing lags of weeks to months. A PM-JAY evaluation published last month may not yet be retrievable via Elicit or Consensus.
→ PubMed direct search and Google Scholar for anything from the last 6 months
⚖️
Equity and distributional outcomes
Most tools are optimised to return aggregate findings. Disaggregated data on who benefits by income quintile, gender, caste, or geography is rarely surfaced automatically.
→ Explicit equity terms in every prompt; Session 3 builds this into the PECO-F F dimension

🧪 Scenario matching — pick your situation
Select the scenario that most closely matches your current task. You will get a specific tool recommendation and a one-line rationale.
Recommended approach
🎯 Key takeaway
No single AI tool covers the full pipeline for health economics and financing work. The practical stack for WHO India is: Elicit for structured extraction from indexed literature, Claude or Humata for interrogating uploaded grey literature and government reports, Dimensions.ai for LMIC-filtered discovery, and manual targeted search for anything recent or government-issued. Session 3 shows you how to frame the question that makes all of these more precise.
