Four ways to solve this.
An honest, category-level comparison.
Start with the layer you need. Expand through the same API.
✓ Included~ Partial or build required✕ Not included
| What you need | Gemina | Build it yourself (raw LLM) | Cloud extraction API | Document-processing platform |
|---|---|---|---|---|
| Flags the fields it is unsure about (per-field confidence, refuses to guess) | ✓high / med / low on every field; low-confidence flagged | ✕returns confident wrong answers; no calibrated confidence | ~raw confidence scores, no refuse-to-guess policy | ~confidence + human-in-the-loop review UI |
| Your own schema + line items, any document type, any language | ✓your fields + line items, any language | ✓but you own the prompt, schema enforcement and validation | ~custom models need labeled training data | ✓trainable via UI |
| Tune accuracy vs speed vs cost (named model tiers, one API) | ✓Invictus / Praetorian / Velox via one parameter | ~swap models manually, no managed tiers | ✕one model per API | ✕not buyer-facing |
| Callable from AI agents over MCP (no integration to build) | ✓MCP-native, plus REST + async webhooks | ~you build the tool wrapper | ✕— | ✕— |
| Privacy as a headline: retention control, residency, never trained on | ✓retention control, residency by country, AES-256 / TLS 1.2+ | ✕you build retention / residency / controls yourself | ~strong cloud compliance, but you assemble the controls | ~enterprise governance, not privacy-first framing |

Capabilities as of June 2026, compared at the category level; individual vendors vary. Gemina is the extraction layer — pair it with your own app or an AP workflow tool.
Built for product teams
Why platforms build on Gemina.
Use Gemina as the document-intelligence layer beneath your own workflow, interface, and customer experience.
Keep your product differentiated
Gemina handles document intelligence. You keep control of the workflow, branding, and experience your customers choose you for.
Ship without infrastructure sprawl
OCR, extraction, search, totals, chat, REST, SDKs, and MCP live behind one platform instead of a chain of services.
Start narrow. Expand later.
Launch with OCR or extraction today, then add richer document capabilities without migrating documents or replacing your API.
Control cost and performance
Match each workload to the right model tier instead of paying top-tier processing costs for every document and field.
The economics
Compare total system cost—not one API line item.
Processing price is only one part of what it costs to ship and operate a dependable document product.
