RecursiveAI.OneOcr

Local, deterministic OCR for .NET. Pure managed code with no dependency beyond the base class library and RecursiveAI.OneImage: no native binaries, no network. Text, boxes and confidences are bit-identical on every CPU path and at every degree of parallelism.

dotnet add package RecursiveAI.OneOcr

using OneImage;
using OneOcr;

OcrEngine engine = OcrEngine.LoadBundled();     // once; the engine is immutable and thread-safe
Image image = Image.Load("invoice.png");

string text = image.ToText(engine);
OcrPage page = image.Ocr(engine);               // blocks, lines, words, tables, boxes and calibrated confidences
string markdown = image.ToMarkdown(engine);

OcrEngine.ConfigureDefault() sets a process-wide engine for the extension methods that take none. Every call takes an optional OcrOptions (an engine carries its own in engine.Options). Ocr(Image) reads one page; OcrPages reads every frame of a multi-page file, takes the resolution a PNG, JPEG or TIFF declares, and reports files it cannot read as OcrFormatException or OcrLimitException. Boxes are always in the image as you gave it, also for pages that came in rotated, and page.Diagnostics carry stable codes.

The package holds the reader, the page model and its oneocr.page JSON, local Markdown, and inference for the invoice, receipt and custom extraction models. The weights come with RecursiveAI.OneOcr.Models, which this package depends on. LLM vision, training, PDF pages and the command-line tool are separate opt-in packages.

Package Downloads
RecursiveAI.OneOcr.Models.Documents

Document extraction weights for RecursiveAI.OneOcr: invoice, receipt and key-value fields. The model is embedded when the package is built with OneOcrDocumentModelFile pointing at the pinned file (see models.json).
RecursiveAI.OneOcr.Training

Fine-tuning for RecursiveAI.OneOcr recognition models from your own documents: an LLM labels the lines, lines the local reader agrees with train the model, the rest go to a review queue. Reaches the network only through RecursiveAI.OneOcr.Llm.
RecursiveAI.OneOcr.Llm

Opt-in language-model vision for RecursiveAI.OneOcr: Anthropic, OpenAI, OpenAI-compatible, Gemini and Azure OpenAI over plain HttpClient. This is the only OneOcr package with networking code.
RecursiveAI.OneOcr.Pdf

PDF bridge for RecursiveAI.OneOcr: text-layer words where a page has them, local OCR for scanned regions, one page model.
