Description from the maker (original English)
Find novel, statistically validated patterns in tabular data — hypothesis-free.

Find novel, statistically validated patterns in tabular data — feature interactions, subgroup effects, and conditional relationships that humans and agents miss.
Made by Leap Laboratories.
Most data analysis starts with a question. Disco starts with the data.
Without biases or assumptions, it finds combinations of feature conditions that significantly shift your target column — things like "patients aged 45–65 with low HDL *and* high CRP have 3× the readmission rate" — without you needing to hypothesise that interaction first.
Each pattern is:
The output is structured: conditions, effect sizes, p-values, citations, and a novelty classification for every pattern found.
Use it when: "which variables are most important with respect to X", "are there patterns we're missing?", "I don't know where to start with this data", "I need to understand how A and B affect C".
Not for: summary statistics, visualisation, filtering, SQL queries — use pandas for those
pip install discovery-engine-api
Get an API key:
# Step 1: request verification code (no password, no card)
curl -X POST https://disco.leap-labs.com/api/signup \ -H "Content-Type: application/json" \ -d '{"email": "you@example.com"}'
curl -X POST https://disco.leap-labs.com/api/signup/verify \ -H "Content-Type: application/json" \ -d '{"email": "you@example.com", "code": "123456"}'
Or create a key at disco.leap-labs.com/developers.
Run your first analysis:
from discovery import Engine
engine = Engine(api_key="disco_...") result = await engine.discover( file="data.csv", target_column="outcome", )
for pattern in result.patterns: if pattern.p_value < 0.05 and pattern.novelty_type == "novel": print(f"{pattern.description} (p={pattern.p_value:.4f})")
print(f"Explore: {result.report_url}")
Runs take a few minutes. discover() polls automatically and logs progress — queue position, estimated wait, current pipeline step, and ETA. For background runs, see Running asynchronously.

Each Pattern in result.patterns looks like this (real output from a crop yield dataset):
Pattern(
description="When humidity is between 72–89% AND wind speed is below 12 km/h, " "crop yield increases by 34% above the dataset average", conditions=[ {"type": "continuous", "feature": "humidity_pct", "min_value": 72.0, "max_value": 89.0}, {"type": "continuous", "feature": "wind_speed_kmh", "min_value": 0.0, "max_value": 12.0}, ], p_value=0.003, # FDR-corrected novelty_type="novel", novelty_explanation="Published studies examine humidity and wind speed as independent " "predictors, but this interaction effect — where low wind amplifies " "the benefit of high humidity within a specific range — has not been " "reported in the literature.", citations=[ {"title": "Effects of relative humidity on cereal crop productivity", "authors": ["Zhang, L.", "Wang, H."], "year": "2021", "journal": "Journal of Agricultural Science"}, ], target_change_direction="max", abs_target_change=0.34, # 34% increase support_count=847, # rows matching this pattern support_percentage=16.9, )
Key things to notice:
The result.summary gives an LLM-generated narrative overview:
result.summary.overview
result.summary.key_insights
Disco is a pipeline, not prompt engineering over data. It:
You cannot replicate this by writing pandas code or asking an LLM to look at a CSV. It finds structure that hypothesis-driven analysis misses because it doesn't start with hypotheses.
Before running, exclude columns that would produce meaningless findings. Disco finds statistically real patterns — but if the input includes columns that are definitionally related to the target, the patterns will be tautological.
Exclude:
diagnosis_text when the target is diagnosis_code)serious, then serious_outcome, not_serious, death are all part of the same classification. If target is profit, then revenue and cost together compose it. If target is a survey index, the sub-items are tautological.Full guidance with examples: SKILL.md
await engine.discover(
file="data.csv", # path, Path, or pd.DataFrame target_column="outcome", # column to predict/explain analysis_depth=2, # 2=default, higher=deeper analysis, lower = faster and cheaper visibility="public", # "public" (always free, data and report is published) or "private" (costs credits) column_descriptions={ # improves pattern explanations and literature context "bmi": "Body mass index", "hdl": "HDL cholesterol in mg/dL", }, excluded_columns=["id", "timestamp"], # see "Preparing your data" above use_llms=False, # Defaults to False. If True, runs are slower and more expensive, but you get smarter pre-processing, summary page, literature context and novelty assessment. Public runs always use LLMs. title="My dataset", description="...", # improves pattern explanations and literature context )
Public runs are free but results are published. Set
visibility="private"for private data — this costs credits.
Runs take a few minutes. For agent workflows or scripts that do other work in parallel:
# Submit without waiting
run = await engine.run_async(file="data.csv", target_column="outcome", wait=False) print(f"Submitted {run.run_id}, continuing...")
result = await engine.wait_for_completion(run.run_id, timeout=1800)
For synchronous scripts and Jupyter notebooks:
result = engine.run(file="data.csv", target_column="outcome", wait=True)
Disco is available as an MCP server — no local install required.

Disco isn't a replacement for EDA or AutoML — it finds the patterns those tools miss. We tested 18 data analysis tools on a dataset with known ground-truth patterns. Most confidently reported wrong results. Disco was the only one that found every pattern.
