Turn your PDFs, spreadsheets, and docs into a chat assistant that answers with citations — and respects who's allowed to know what, level by level.
Your documents. Your LLM, if you want. Your access rules, always.
“We know more than we can tell.”
Every organization runs on knowledge that is technically written down — in policy PDFs, project reports, spreadsheets, and wikis — yet practically silent. People re-ask questions that were answered years ago, or worse, guess.
Tacitto gives that silent knowledge a voice. Upload your documents once, and everyone gets instant, cited answers — while your access rules decide exactly who can hear what.
Drag in the files your organization already has. Tacitto reads, chunks, and indexes them automatically — no reformatting needed.
Tag every document with a level — company-wide to executive-only. Each person you invite gets a level too. That's the whole permission model.
Everyone gets a familiar chat interface. Answers stream in with citations to the exact page — grounded only in documents they're cleared to see.
Most AI assistants answer everyone the same way. Tacitto checks the asker's level first. Try it — same question, different clearance:
Each response links to the document, page, or row it came from. Click through and verify — no black-box answers.
One integer per document, one per user. Level 3 sees levels 1–3, never 4. Enforced server-side on every single query.
Plug in your OpenAI, Anthropic, Groq, or Google key — or use ours. Your key stays encrypted; switch providers anytime.
Analytics show the questions your knowledge base couldn't answer — so you know exactly which document to add next.
Drop a snippet on your website and let visitors chat with your public-level content. Same brain, your branding.
Test your knowledge base as any level before rollout. See exactly which passages each role can retrieve.
Every organization gets its own dedicated vector database. Your documents are never indexed, stored, or searched alongside anyone else's.
LLM API keys are encrypted at rest and never shown again. When Tacitto doesn't know, it says so — it won't invent an answer your documents don't support.
Uploads, deletions, level changes, and sign-ins land in an immutable audit trail your admins can search and export.
PDF (including scanned documents), Word, plain text, Markdown, Excel, and CSV. Tacitto parses each format natively — spreadsheets keep their column context so tabular answers stay accurate.
Nothing leaks. The level filter is applied inside the retrieval engine on every query, so restricted content is never even considered — it can't appear in answers, citations, or summaries. The assistant simply says it doesn't have that information.
Yes. Add your OpenAI, Anthropic, Groq, or Google API key in settings; it's encrypted at rest and used only for your organization's requests. No key? Tacitto's built-in default model works out of the box.
Never. Each organization's knowledge base lives in its own dedicated database. Your documents are not used to train any models, and deleting your account destroys your data entirely.
Reupload a file and Tacitto swaps it atomically — the assistant never answers from a half-updated document. Delete a file and its knowledge is gone from answers immediately.
