What Orinis is
This service is operated by Cairn AI, LLC d/b/a Orinis. Orinis is a bi-temporal memory service. You store messages and derived timeline events; Orinis answers from those records. It is not a general chatbot and does not invent history from model weights when your archive has no matching record.
Your account
You must provide a working email address and verify it before using product features. You are responsible for keeping your password confidential and for activity under your account. You must be able to form a binding contract where you live; we do not knowingly offer the service to children under 13.
Documents you upload
You can upload PDFs. Orinis reads the text and derives timeline events from it. If a page has no text layer — a scan or a photographed page — it is read by optical character recognition (OCR) that runs on our own servers using the open-source Tesseract engine. No third party sees the file for OCR.
When you upload a document, the file itself is not kept. Your archive records the file name as its entry, not the document. Orinis keeps the events read from the document and, with each event, the text it was read from: the sentence or table row that produced it, when that passage matches the document word for word. When it doesn’t, the event keeps a larger span instead, up to the whole of the document’s text, so text that produced no event can be kept too. Because the document itself is not kept, Orinis cannot re-read it later.
The document’s text is sent to a model provider while it is being processed, to find dates and events in it — the narrative and the rows of any table alike. Each table row is turned into a sentence and read individually, so a long table means many separate reads. See the Privacy Policy for who processes what, and when.
One part is not left to the model: a record’s date is taken from the document’s own text rather than inferred — which makes it the document’s date and not a guess, but not necessarily the right one, because Orinis can read it from the wrong cell. A date Orinis cannot read produces no record at all rather than a guessed one. What the row means — its title, its type, the details — is the model’s reading of it, and can be wrong in the ordinary way any reading can be wrong.
Orinis does not store the prompts it sends or the responses it receives — only a count of calls made.
A record states what the document asserted. Orinis does not check an assertion against the rest of the document, or against anything else in your archive. If a report’s narrative says a site is clear while its own table says otherwise, Orinis records the narrative and will repeat it back to you with a citation. Citations show what your archive records, not that the record is correct — they establish where a statement came from, not whether it is true. This matters most for documents you did not write yourself.

Plans and billing
Published prices are on the pricing page.
Payments are non-refundable, including for partial periods. Cancelling stops future billing; it does not refund the current period. This does not affect refund or cancellation rights you have under applicable law.

Your content
You retain rights to the content you submit. You grant Cairn AI, LLC d/b/a Orinis a limited license to store, process, and display that content solely to operate the service for you (extraction, retrieval, export formats you request, and related operations described in the Privacy Policy).
How long we keep your data
Indefinitely, until you delete it. Orinis does not expire, archive, or age out your records on a schedule — a memory layer whose contents quietly disappeared after a year would not be one. There is no retention period to configure and none running in the background.
Deletion is yours to trigger, at two granularities: a single message and everything derived from it, or the whole account. Both are described in the Privacy Policy, including the parts that survive and why.
Service changes and availability
We may change or discontinue features with reasonable notice when practical. The service is provided “as is.” We aim for reliability but do not guarantee uninterrupted availability.
If Orinis stops running, your archive is portable and you do not need us to get it. Settings → Export all data produces a single JSON file containing your messages, the events derived from them, their projects, links and corrections, with original and recorded timestamps preserved, plus your answer history and its citations. Every export carries a manifest — a count of each collection and a SHA-256 digest of the contents — so you or anyone you hand the file to can confirm nothing was lost or altered, using the file alone, without asking us.
Export works today and is not conditional on a wind-down. We recommend taking one whenever the archive matters to you. The Privacy Policy states exactly what the export covers, what it does not, and what the manifest does and does not prove.
Limitation of liability
To the fullest extent permitted by law, Cairn AI, LLC d/b/a Orinis and its operators are not liable for indirect, incidental, or consequential damages, or for loss of data beyond our obligation to use reasonable care. Nothing here limits rights that cannot be waived under applicable law.
