The engine that sees your creatives (Gemini Embedding 2), extracts their DNA automatically, and proves what causes performance.
Not vibes. Not correlations. Proof.

Everyone knows which creatives performed. Nobody knows why. OmniProof does.

Upload any creative — video, image, PDF. OmniProof embeds it (Gemini Embedding 2), extracts structured metadata automatically, estimates causal effects with Double Machine Learning, and checks brand compliance via RAG. The output isn't a dashboard of correlations. It's proof: "blue backgrounds cause a +12% CTR uplift for 18-24, controlling for platform, budget, and seasonality."

Quick Start

pip install omni-proof

Or install from source

git clone https://github.com/navidgh66/omni_proof.git
cd omni_proof
pip install -e ".[dev]"

Requires Python 3.11+. The causal analysis layer works with local data only — no API keys needed. For the full pipeline you'll need a Gemini API key and a Pinecone account.

Try it now — zero setup, zero API keys:

python examples/demo.py   # 9-stage pipeline demo in ~4 seconds

Or use it as a library:

import pandas as pd
from omni_proof import DMLEstimator

data = pd.read_csv("examples/data/campaign_performance.csv")
estimator = DMLEstimator(cv=5, n_estimators=50)

# Does fast pacing *cause* higher CTR?
ate = estimator.estimate_ate(data, "fast_pacing", "ctr",
    ["platform", "audience_segment", "daily_budget_usd"])
print(f"ATE: {ate.ate:+.4f} (p={ate.p_value:.4f})")
# ATE: +0.0189 (p=0.0001)

# For which segments?
cate = estimator.estimate_cate(data, "fast_pacing", "ctr",
    ["platform", "daily_budget_usd"], segment_col="audience_segment")
for seg, eff in cate.segments.items():
    print(f"  {seg}: {eff.effect:+.4f} (p={eff.p_value:.4f})")
# Gen-Z 18-24:    +0.032 (p=0.001)  — strong
# Millennials:     +0.015 (p=0.023)  — moderate
# Gen-X 35-44:    +0.003 (p=0.412)  — not significant

4. Brand Compliance	RAG: embed guidelines → retrieve → evaluate	Yes
5. Causal Analysis	DAG → DML → ATE/CATE → refutation	No
6. Embeddings + Causal	Merge Pinecone embeddings with campaign data	Yes
7. DICE-DML	Counterfactual pairs → treatment fingerprint → visual ATE	Yes

Highlights

• Causal Engine -- DML + refutation tests isolate true treatment effects from confounders. Not correlations.
• Multimodal Embeddings -- Gemini Embedding 2 maps video, images, audio, PDFs, and text into a shared 3072-dim space.
• Brand Intelligence -- Extract structured brand guidelines from any asset, then auto-check new creatives for compliance.
• DICE-DML -- Disentangle visual confounders from treatment signals using counterfactual embedding pairs.
• Creative Generation -- Causal insights feed directly into optimized creative prompts.
• REST API -- 12 endpoints covering brand extraction, compliance, causal analysis, and generation.
• Modular -- Use the full pipeline or any layer independently as a library.

Architecture

OmniProof is organized into five layers. Each can be used independently:

Layer	Module	Key Classes
Ingestion	omni_proof.ingestion	GeminiClient, AssetPreprocessor, IngestPipeline
Storage	omni_proof.storage	PineconeVectorStore, InMemoryVectorStore, RelationalStore
Causal	omni_proof.causal	CausalDAGBuilder, DMLEstimator, CausalRefuter, VisualDMLEstimator
Orchestration	omni_proof.orchestration	ComplianceChain, InsightSynthesizer, BrandExtractor
API	omni_proof.api	FastAPI app, routes, GenerativePromptBuilder

Key Abstractions

Interface	Purpose	Implementations
EmbeddingProvider	Generate embeddings from any content	GeminiClient
VectorStore	Store and search vectors	PineconeVectorStore, InMemoryVectorStore
Estimator	Estimate causal effects	DMLEstimator

Configuration

Set environment variables with the OMNI_PROOF_ prefix, or pass them programmatically:

OMNI_PROOF_GEMINI_API_KEY=AIza...
OMNI_PROOF_PINECONE_API_KEY=pcsk_...
OMNI_PROOF_PINECONE_INDEX_HOST=https://my-index-abc123.svc.pinecone.io
OMNI_PROOF_DATABASE_URL=sqlite+aiosqlite:///./omni_proof.db  # default

Variable	Required For	Where to Get
OMNI_PROOF_GEMINI_API_KEY	Embeddings + extraction	Google AI Studio
OMNI_PROOF_PINECONE_API_KEY	Vector storage	Pinecone Console
OMNI_PROOF_PINECONE_INDEX_HOST	Vector storage	Pinecone Console
OMNI_PROOF_DATABASE_URL	Relational storage	PostgreSQL or SQLite URI

Causal Methodology

OmniProof implements a four-stage causal pipeline:

1. Model -- Build a DAG mapping treatments, outcomes, and confounders
2. Identify -- Apply the backdoor criterion to find valid adjustment sets
3. Estimate -- Double Machine Learning (Neyman orthogonalization) via EconML
4. Refute -- Placebo tests, subset validation, and random confounder checks

For visual embeddings where treatment and confounders are entangled, DICE-DML generates counterfactual pairs, isolates treatment fingerprints via vector subtraction, and applies orthogonal projection before estimation.
