The short version: Quill and Adentris both work in behavioral health documentation, but they solve different halves of the problem. Quill, from Quill Therapy Solutions, writes therapist progress notes from a short typed session summary, without recording, to paste into any EHR. Adentris is a revenue integrity and documentation compliance layer that reviews the note, however it was written, in real time before the claim is submitted, with SUD-specific rules like ASAM level of care and 42 CFR Part 2 and an appeals and denials module built in. If your problem is note-writing time, Quill is built for that. If your problem is denials and audit exposure, that is where Adentris focuses.
Both work on the therapy note, so a head-to-head comes down to whether your problem is writing it or getting it paid. Here is the breakdown.
What Adentris does
Adentris is an AI platform for revenue integrity and documentation compliance built specifically for behavioral health and SUD programs. It works on top of the EHR you already run, connecting through an API or HL7 where one exists (for example Alleva, Pimsy, Kipu, Epic, or Athenahealth) and through a secure web agent where it does not, so there is no migration. It reviews notes in real time and flags the elements that get behavioral health claims denied before the claim is submitted: medical necessity, ASAM level-of-care justification, treatment plan updates, group therapy attendance, service units, signature timing, and 42 CFR Part 2 consent. When something is missing, it drafts the correction for the clinician to accept, and it pairs documentation review with an appeals and denials module. Adentris is not a scribe: it does not write the note, it makes sure the note will get paid. Adentris is HIPAA compliant and SOC 2 certified, with 42 CFR Part 2 controls and BAAs in place.
What Quill does
Quill, from Quill Therapy Solutions, is an AI documentation tool for therapists that turns a short typed session summary into a full progress note, without recording or storing the session, so clinicians can paste the result into any EHR. It is designed to be a fast, privacy-conscious way to reduce note-writing time. For therapists who prefer a summary-to-note workflow over ambient recording, Quill is a focused option.

Which should you choose?
Quill is built to turn a quick summary into a finished note fast, without recording. Adentris is built for a different job: catching the documentation gaps that get behavioral health and SUD claims denied and fixing them before submission. It flags a missing medical necessity statement, an unjustified ASAM level of care, or a missing 42 CFR Part 2 consent, drafts the correction while the note is open, and supports the appeal if a payer denies. For SUD programs, ASAM and Part 2 depth, real-time pre-submission timing, and running on any EHR through a secure web agent are the practical differences. A clinician can use Quill to write the note and Adentris to make sure it gets paid.
- Choose Quill if you prefer a fast, privacy-conscious summary-to-note workflow without ambient recording, pasted into your EHR.
- Choose Adentris if you run a SUD or behavioral health program and the real pain is denied claims: you want denial-driving gaps like ASAM level of care, medical necessity, and 42 CFR Part 2 caught and corrected before submission, with a paired appeals and denials module, on any EHR.
Adentris as a Quill alternative for revenue integrity
If your practice uses Quill, or is evaluating it, and the gap you feel is not note-writing time but denied claims and audit exposure, that is a different job. Adentris reviews the finished documentation against payer and regulatory denial criteria, drafts the correction before submission, and pairs that with an appeals and denials workflow. It runs on any EHR through an API, HL7, or a secure web agent, so it fits alongside a note-writing tool rather than replacing it. For clinicians who write notes well but still lose claims, it is a natural complement.
How Adentris helps
For behavioral health and SUD organizations, the biggest revenue leak is documentation, and it is specific: medical necessity that was never shown, missing ASAM justification, a Part 2 consent that was not captured. Adentris reviews every chart in real time inside your existing EHR and flags exactly those gaps before the claim is filed, then drafts the fix, and it pairs that with an appeals and denials module so compliance and revenue integrity live in one place. At Sobrius Health, a multi-site Virginia SUD provider, pre-submission documentation accuracy moved from 73% to 96%. Adentris is HIPAA compliant and SOC 2 certified, with 42 CFR Part 2 controls and BAAs in place. To see it on your own charts, book a 30-minute call with our team.
The bottom line
Quill is a fast, privacy-conscious way to write the note. If your losses come from denied claims rather than slow notes, Adentris reviews the finished note before submission for ASAM and Part 2 gaps and pairs it with appeals, on any EHR.

Quill helps write the note; Adentris makes sure it gets paid.
Can Adentris and Quill be used together?
Yes. They solve different halves of the problem, so a program can use Quill to write the note from a summary and Adentris to verify the documentation supports the claim and to handle appeals. Adentris reviews the note however it was written, so it fits alongside Quill.
Is Adentris a good alternative to Quill?
For programs whose problem is denials and audit exposure rather than note-writing time, yes. Adentris focuses on catching and correcting the behavioral health and SUD gaps that drive denials before submission, with ASAM and 42 CFR Part 2 built in and an appeals and denials module, and it runs on any EHR without a migration.
Which is better for a substance use disorder program?
For SUD, the claims that get denied usually turn on ASAM level of care, medical necessity, and 42 CFR Part 2, which Adentris is built around with real-time, pre-submission review and drafted corrections. Quill is strong for fast summary-to-note documentation for therapists. Programs that want SUD-specific compliance depth and denials support often lean Adentris.
