FullCorpus AI: Presenting the software, its functions, how it works, and its reliability

Version 2.5 (July 2026)

From corpus to results
in 3 steps.

Document corpus
Step 1

Load the corpus

Add your PDFs, articles, or text documents. The software automatically detects and organizes them.

Data extraction by software
Step 2

Software extracts data and we tabulate it

The software applies the same criteria to each document individually — data is automatically tabulated.

Results report
Step 3

Results report

Results are consolidated into an exportable report with syntheses, clusters, and full traceability.

How long does
each analysis take?

It depends on the number of data points to be analyzed. Our average estimate is approximately 1 hour per 100 documents.

How reliable
is the tool?

According to our tests, data extraction achieves near 100% accuracy — surpassing manual reading in exhaustiveness and consistency. Errors are still possible, which is why every analysis is traceable and reviewable. Reliability is further reinforced by adequacy crosschecking analyses, which verify the correspondence between what was extracted and the original documents.

We didn't reinvent
the wheel.

FullCorpus AI is not an AI or an LLM. It is software that automates the use of LLMs (GPT, Gemini, and Claude). Its reliability is therefore on par with high-effort, high-reasoning models.

Rigor and
exhaustiveness.

Data is not mixed in bulk — each document is analyzed individually, with the same criteria applied one by one. It is like running the same prompt for every document, on a model with the highest reasoning effort.

At what stage
is it valid?

We recommend it as a pre-analysis stage — an initial round of analysis, often also simulating possible results and findings. Researcher review and analysis are still necessary.

🏢

Big Tech APIs, not proprietary models

We use developer APIs from GPT, Gemini, and Claude — with greater context capacity and performance than chat interfaces.

Superior to chatbots in exhaustiveness

While chatbots answer one question at a time, FullCorpus AI applies the same criteria to hundreds of documents with fidelity and consistency.

⚠️

Still AI: review recommended

Errors can occur. That is why every analysis is documented and reviewable — traceability is part of the process, not an add-on.

Everything you need
in one place.

Batch Processing

Analyze dozens or hundreds of documents in sequence, with the same prompt and criteria applied to each one.

🔁

Multi-Model

Choose GPT, Gemini, Claude, or others for each task. Switch models without reconfiguring the workflow.

📋

Structured Output

Results in tabular format (.xlsx, .csv) with one row per document, ready for statistical analysis.

🔍

Full Traceability

Every analysis records the model, version, temperature, and prompt used — with a unique identification hash.

📁

PDF and Text Support

Import PDFs, scientific articles, .txt and .docx documents. The software prepares and normalizes them automatically.

🌐

Multi-Language

Analyze documents in Portuguese, English, Spanish, and other languages — with prompts in any language.

The best LLMs,
in a single tool.
