Your AI knows your business — not the entire internet
Upload PDFs, manuals, contracts, and spreadsheets. Synapse organizes, indexes, and answers based on your real documents, always citing the source. The proprietary rerank makes sure the right answer ends up on top — not the one that merely looks most like the question.
From loose file to sourced answer
Four steps, with a person in control of the second. Nothing enters the base without someone approving it.
PDF, DOCX, XLSX, CSV, document images. Drag them onto the screen or connect the folder and the system you already use.
Splitting into chunks, metadata extraction, and indexing. Before anything counts toward answers, a person approves what came in.
Semantic search retrieves candidates; the proprietary rerank reorders them by what actually answers the question.
Every answer comes with document and page. If the source doesn't support the answer, the application says it doesn't know.
Pick a question and see where the answer comes from
The retrieved chunks appear with their search score and their score after the rerank. That reordering is what changes the result.
One base shared by every application in the company
Dedicated Lakehouse
Each company has its own, isolated. Documents, spreadsheets, databases, and systems feed the same base — so every application understands the business the same way.
Proprietary rerank
The second search layer reorders candidates by real relevance to the question. It's where the 3–5× precision gain over a plain RAG comes from.
A preference for silence
When no chunk supports the answer, the application says it didn't find one and opens a path to a person. We prefer that over a well-written wrong answer.
Continuous updates
A new price table, a revised policy, a signed contract: it enters the base and starts counting in the answers that follow, with the old version preserved in the history.
Permission at the chunk level
Whoever can't see the document doesn't get an answer based on it. Permission applies at the source, not just on screen.
Your data trains no one
Nothing that enters your base is used to train third-party models. For sensitive content, the query can stay restricted to your environment.
The base decides what your AI knows. The router decides which brain it thinks with.
Bring ten documents. We build the base right in front of you.
In the technical demo we upload your files, ask the questions your team asks every day, and show the citation behind every answer.
