AI toolkit for your DataFrames

AI toolkit for tabular data -- auto EDA, data profiling, anomaly detection, and smart transformations on DataFrames. The pandas AI companion.

Runs completely offline. All processing uses local pandas/numpy/scikit-learn. No cloud APIs or internet connection required.

Installation

pip install tableai

With optional dependencies:

pip install tableai[ml]    # scikit-learn for Isolation Forest anomaly detection
pip install tableai[viz]   # matplotlib + seaborn for visualizations
pip install tableai[all]   # everything

Quick Start

import pandas as pd
import tableai

df = pd.read_csv("your_data.csv")

# Computes per-column statistics: dtypes, null counts, unique values,
# numeric stats (mean/median/std/quartiles/skewness), correlations
# Returns DataProfile with rich notebook display
report = tableai.profile(df)
print(report)

Output:

=== Data Profile ===
Shape: (1000, 8)
Memory usage: 62.6 KB

Column Profiles:
  age (int64)
    Non-null: 950 / 1000 (95.0%)  |  Unique: 60
    Mean: 35.2  |  Std: 12.1  |  Min: 18.0  |  Max: 75.0

  city (object)
    Non-null: 980 / 1000 (98.0%)  |  Unique: 25
    Top values: New York (120), London (98), Tokyo (85)
...

Auto-Clean

# Auto-cleaning: fills nulls (median/mode), removes duplicates,
# clips outliers via IQR method
cleaned_df = tableai.clean(df)

Anomaly Detection

result = tableai.anomalies(df)
print(result)

Output:

=== Anomaly Report ===
Method: iqr
Total rows flagged: 42 / 1000 (4.2%)

  salary: 18 anomalies (min_bound=20000, max_bound=150000)
  age: 7 anomalies (min_bound=5, max_bound=80)
...

Auto Insights

insights = tableai.insights(df)
for insight in insights:
    print(f"- {insight}")

Output:

- Column 'age' has 5.0% missing values
- Strong positive correlation (0.87) between 'hours_worked' and 'salary'
- Column 'income' is highly skewed (skewness=2.31)
- Column 'city' has high cardinality (250 unique values out of 1000 rows)

DataFrame Comparison

diff = tableai.compare(df_old, df_new)
print(diff)

Smart Transformations

transformed_df = tableai.transform(df)
# Auto-encodes categoricals, scales numerics, extracts datetime features
