Quickstart (Python)

OCR now runs a single quality level. The `tier` parameter is still accepted — `tier: "fast"` returns the same result as `pro` — so existing integrations keep working unchanged.

import base64, httpx
img = base64.b64encode(open("document.jpg", "rb").read()).decode()
resp = httpx.post(

print(resp.json())

Notes:

• Brainiall S8 v1 covers the Brainiall OCR engine (English printed text → clean Markdown). Multi-language OCR (80+ languages) is on the roadmap for a later release.

vs Mistral OCR 3 (December 2026)

Mistral OCR 3 launched December 2026 at $0.002/page with SOTA quality on tables, figures, and math equations. It is the most disruptive new entrant in the OCR category — and we are honest that on raw OCR quality across complex documents, it likely leads. Here is how S8 (Brainiall OCR engine) fits next to it.

• Raw OCR quality: Mistral leads on math/figures/multi-column scientific layouts. S8 (Brainiall OCR engine) is solid on receipts, invoices, and technical documentation.
• Clean Markdown output: S8 (Brainiall OCR engine) returns clean Markdown text — headings, tables and lists preserved — ready to feed an LLM, instead of raw characters and bounding boxes you have to reassemble. Mistral returns plain text + bounding boxes.
• Confidence scoring: Per-block confidence scores on every response, so you can gate low-quality scans at the API boundary instead of letting them leak into your downstream agents.
• Audit trail: Per-call audit DB row with 90-day retention. Mistral is a stateless API; you bring your own logging.
• Self-host option: Production-grade engine (Brainiall OCR engine, permissive license / MIT). Auditable for regulated industries and airgap-deployable. Mistral is API-only.
• Price: $0.00075/page (S8) vs $0.002 (Mistral). ~2.7× cheaper — and includes per-call audit trails Mistral omits.

When to pick Mistral: pure cheap OCR, no downstream pipeline, SOTA quality required on math/figures.

When to pick Brainiall: need clean Markdown text output, a per-call audit trail for compliance, or self-host capability for airgap deployments. For structured field extraction, use Brainiall Document Intelligence.

LLM-ready output at a fraction of traditional OCR cost

Every endpoint in the Brainiall document family returns text your pipeline can use immediately — clean Markdown, typed JSON fields or structured tables — not a raw OCR dump you still have to post-process. And it does so at simple per-page prices that come to a fraction of traditional cloud OCR suites and their per-feature billing matrices.
