Microbial electrochemical systems · research intelligence
MESSAI unifies a curated microbial-electrochemistry corpus, a causal parameter model, and a calibrated ML stack — so you can discover what’s known, design a reactor in 3D, and predict performance with honest uncertainty.

What researchers can do here
Every surface reads from the same curated corpus and the same calibrated model stack — so what you discover, analyze, and predict all trace back to source.
Semantic search across the corpus, plus an AI assistant that answers from retrieved papers and cites real DOIs — no fabricated sources.
Search the corpus →Browse canonical parameters with per-system literature distributions, hierarchical priors, and confidence — not single-number folklore.
Open the catalog →See how parameters depend on one another through a fitted causal graph and a force-directed knowledge graph of correlations and provenance.
Explore the DAG →Build a bioelectrochemical reactor in the 3D lab and get live performance predictions with calibrated uncertainty and mechanistic loss breakdowns.
Open the lab →Fix your operating conditions, sweep one variable, and watch predictions move against the empirical distribution from the corpus.
Run a sweep →A research-scan view of physics-violating results, statistical anomalies, and Bayesian outliers worth a closer look.
Open the hunter →How it works
The same pipeline feeds every surface. Each stage is auditable — you can trace any number on the platform back through calibration, canonicalization, and extraction to the paper it came from.
20k+ MES papers ingested, with full-text PDFs content-addressed and embedded for semantic retrieval.
Two-tier LLM extraction pulls measurements with their conditions — every value keeps its DOI, snippet, and confidence.
Raw values are normalized to SI and mapped to canonical parameters, so numbers from different papers become comparable.
Hierarchical Bayesian priors (PyMC, log-normal) per system class, wrapped in conformal intervals with measured coverage.
Per-physics-family predictors return every output as {value, unit, ci_low, ci_high, confidence, source} — never a bare point estimate.
Design a reactor and see the prediction, the empirical evidence behind it, and the mechanistic loss decomposition side by side.
