The problem you already own
The obligation you already have
Title VI of the Civil Rights Act and Section 1557 of the ACA require federally funded providers to give meaningful language access. Most organizations meet it today with a per-minute phone interpreter line — roughly $1–4 a minute, booked in advance, with hold time on the clock.
Tiyol is the same job at a fraction of that, available the moment someone picks up the phone.
And it covers the calls you are not covering at all. Your interpreter line works while the patient is in your building. It does nothing at 8am on a Tuesday when she is at her kitchen table holding a denial letter — which is where most of these calls actually happen, and where the cost of getting a number wrong lands back on you.
The part that is not a claim
Every call produces a record
Interpretation is table stakes; everyone selling into this category offers it. The written artifact is the part that does not exist elsewhere — and the reason it exists is a failure we measured in our own testing.
Not resolved. Patient needs to call back.
Called: Example Health — customer service
- The 12 June claim was denied. Reason given: no prior authorization.
- Appeal is available. 60 days from the date of the letter.
- The letter is dated 24 July.
Patient said «ese» (S); the line heard «efe» (F). Confirm against the card.
- Appeal filed before 22 September.
- Full member number confirmed.
Speech recognition corrupted an alphanumeric member ID in four out of four test calls — dropping the letter, hearing it as a digit, hearing it as a different letter. No prompt fixes that; the weak link is recognition itself. So we do not silently correct identifiers. We flag the ones the line probably got wrong and put them in front of the one person who can check: the patient holding the card.
The strongest signal is emergent and fully deterministic — when the caller and your staff each state the same ID and the two renderings disagree, that disagreement ranks to the top of the queue automatically.
In your vocabulary: a wrong member ID is a denied claim, a failed eligibility check, a duplicate chart, and a callback. You are paying for those today with no way to see where they came from.
Stated plainly, before you ask
What we are, precisely
Diligence
Where your data goes
- Where it runs. One server in Leesburg, Virginia, on OVH US infrastructure. Media transport is our own self-hosted LiveKit, on that same machine — not a third-party realtime platform. Recognition, translation and speech are not: see the next line for exactly who receives call content.
- Subprocessors — four, all reached at US endpoints. Deepgram receives call audio and returns text. Anthropic receives that text and returns the translation and the summary. Cartesia receives the translated text and returns audio. CallNode is the carrier and sends the SMS. No analytics, no trackers, and no third-party fonts at runtime.
- Retention today: indefinite. We keep the transcript, the summary and the originating phone number until deletion is requested. Scheduled deletion is not implemented. We are not going to quote you a retention window we do not enforce — when it ships, the number appears on this line.
- Deletion on request, per call or per number, confirmed back to you.
- We do not sell data, and we do not train models on your calls.
- No BAA today. If you are a covered entity, that is a blocker, and you should hear it now rather than discover it at signature. Tell us what your counsel requires.
Honest status
Where we are
Tiyol is early. Spanish and English work today. Other languages ship only after end-to-end quality is verified in that language, because a confidently wrong interpretation is worse than none at all.
If you run a clinic, a school district, a county programme or a property portfolio and want to try it with real calls, we would like to hear from you — including if the answer after a pilot is no.
