Semantic search over your documentation - with no LLM at query time.
Zero hallucination. Zero per-query cost. Returns in milliseconds.

Live demo · VS Code docs

Watch an AI quote your documentation.

Your AI asks a question. Ragionex returns the exact passage - with source, with media, without inventing a single word.

How it works

Three steps. One simple HTTP call.

Drop your docs in. We turn the chaos into context your AI can trust.

1 UPLOAD

Send your docs.

Send us PDFs, DOCX, Markdown, HTML. Text, images, video - all of it. We turn the messy reality into clean context your AI can use.

2 PROCESS

We do the messy work.

Every image, diagram, and recording in your docs is indexed and searchable. Built to find the right answer every time.

3 QUERY

Your AI retrieves.

POST a question to /v1/knowledge/search. We return the most relevant passages with sources - ready to quote inside your model's context window.

What makes it different

Built for the part of context engineering nobody wants to maintain.

We did the engineering most teams underestimate. Six months of context infrastructure, distilled into one HTTP call. You ship the AI.

01 / Retrieval

Semantic, not keyword.

Real users phrase things badly. We made it not matter. Same answer, every time.

02 / Cost

Zero runtime AI cost.

Every query: instant, predictable, free. No AI bills at runtime. We did the heavy lifting once, upfront. You just ask.

03 / Media

Images, videos, animations & diagrams are searchable.

Half your docs are images. Most search engines treat them like decoration. We taught ours to see. Users find answers inside the picture.

04 / Speed

Returns in milliseconds.

Purpose-built retrieval runs entirely on our infrastructure. Your AI gets context faster than it can start generating a single token.
