Neurosymbolic Loon AI® · Peer-reviewed · Independently validated
Confidence-calibrated AI systematic literature review
Loon Lens™ automates the systematic review process — from deduplication, study classification, and screening through study mapping, data extraction, and quality assessment — with calibrated confidence that routes the rare uncertain decision to human review.
Evidence that lands.
Systematic reviews are slow, costly, and error-prone.The evidence base doubles every 73 days.
The average systematic review costs $141K and takes 67 weeks. Expert extraction covers only 50–54% of baseline data, and 85% of published SLRs contain extraction errors — despite 9 million person-hours spent on reviews every year.
Loon Lens™ compresses this cycle: peer-reviewed, confidence-calibrated agentic AI that takes teams from eligibility criteria to an audit-ready, analysis-ready evidence base — in days, not years.
The platform
One platform from search through screening, mapping, and extraction
Confidence-calibrated
AI systematic lit reviews
Just assess eligibility criteria and upload citations — no pre-labelling, no pre-training, no fine-tuning. Specialised Loon AI® agents deduplicate, enrich, and classify on ingest, then screen, reason, challenge, and adjudicate decisions independently.
- One-shot extraction from tables, figures, and text — harmonised across studies, no caps
- Automatic PRISMA 2020 flowchart, study mapping, and per-datapoint provenance
- Any study design or review type — treatment effects, prognostic, cost-effectiveness, qualitative

How it works
From eligibility criteria to audit-ready evidence
You bring the eligibility criteria and the citations. Specialised Loon AI® agents do the rest — reasoning, challenging, and deliberating with full provenance at every step.
- Eligibility criteria (PICO / PEO)
- Citation records from any database
- Optionally, specific variables to extract — by default, we extract everything
That is the entire setup — no pre-labelling, no fine-tuning.
- Deduplicates, enriches, and classifies citations on ingest
- Screens titles, abstracts, and full text — multi-agent
- Maps multiple reports to their main studies
- Auto-generates the data schema and extracts every datapoint from tables, figures, and text — one shot, unrestricted by number of studies, columns, or variables
- Adjudicates disagreements and routes low-confidence items to human review
- Harmonised, analysis-ready dataset — multi-sheet Excel, R/Python-ready
- Dynamic PRISMA flowchart and automated study mapping
- Per-datapoint provenance with the exact source quote
- Calibrated confidence on every decision and value extracted
- Full audit trail and QC with Loon AI® reasoning per decision
Compress the evidence cycle. From months of manual screening to a single pass — fully autonomous or with human-at-the-helm confidence-routed validation that sends only the rare uncertain decision to an expert reviewer.
The complete evidence lifecycle
Together, Loon Lens™ and Loon Waters™ — Loon's reimbursement-forecasting platform — take teams from literature search through to payer-ready value evidence, compressing the entire evidence cycle.
Calibrated confidence
The only AI that knows when it is uncertain
Every Loon AI® decision carries a calibrated confidence score. Uncertain decisions — typically under 6% — are automatically routed to targeted human review, so teams review only what needs review, not everything or nothing.
Confidence-guided review of just ~5% of records raised precision from 63% to 89.9% and specificity to 99.1%, with 99.0% sensitivity and 99.0% accuracy — validated across 3,796 citations from 8 CDA-AMC reviews.

Reem El SherifHealth Services Researcher · Affiliate Member, Department of Family Medicine, McGill UniversityI used Loon Lens for my most recent review, and what a game changer. I have been using other software for over a decade, and you can only start using it once you have a clean bibliography of potentially relevant records. With Loon Lens I could start using the software once I had a review question: it helped me refine the question, eligibility criteria and search strategy, then cut my review time by more than half by allowing me to focus only on screening the relevant records. Gamechanger!
Paul AroraCEO, Inka Health · HEOR consultancy specializing in bespoke data analysis, acquired by Onco-InnovationsGhayath and I have been working together on several projects for pharma. Working with Loon has been a real value add for Inka Health and I have been blown away by the tech they have developed.
Eva TsakonasConsultant Epidemiologist, Health EconomistI chose to test this first SLR because it was particularly challenging. Loon was able to identify all the citations that had been included manually in the systematic review.
