TL;DR Colorado's Attorney General is taking written comments on proposed rules for the ADMT Act (SB 26-189) and the chatbot law (HB 26-1263) until 11:59 PM on October 26, 2026. The hearing is the same day at 10 a.m. in Denver, with a remote option. This page has a fill-in comment letter, a menu of positions on the open issues, a numbers worksheet and a 3-minute hearing script. Comments are posted publicly, so write for a regulator and a competitor at the same time.
The proposed rules were filed August 11, 2026, and SB 26-189 takes effect January 1, 2027. The Attorney General is due to adopt rules by then. Comments received by the October 26 deadline are the last chance to change the text before the final rules.
Most businesses will not comment. That is the opportunity: a short, specific, well-evidenced letter from a real deployer carries weight that a general objection does not. This page gives you the structure. You supply the facts.
This is a drafting aid, not legal advice. Have counsel read your letter before you file it, especially if you operate in several states.
Before you write: facts to confirm
The sources we read disagree on a few details, and a revised draft may have changed the numbering. Check each of these on the Attorney General's rulemaking page at coag.gov/ai before you file.

The rule numbers below follow the August 11 proposal as summarized by law firms: Rule 5 (developer disclosures), Rule 6 (adverse outcome notices, with the data-source duty reported as Rule 6.6 in some summaries), Rule 7.7 (human review) and Rules 8 to 13 (chatbots). If a revised draft renumbered them, cite the new numbers.
What the proposal would require
You need this in front of you to write specific comments. As reported by the law firms we read:
- Adverse outcome notice. Within 30 days, in plain language through at least two channels and in at least 12-point type if printed. It must name the decision, describe the tool's role and any human reviewer's role, state the principal reasons for the outcome "with specificity", explain inferences and the data behind them, disclose actual scores where a score drove the outcome, flag missing information, and identify data sources by name. One summary adds that a deployer that cannot explain how the technology influenced the decision does not comply.
- Human review. A consumer can ask for meaningful human review. The deployer must confirm receipt within 10 days and finish within 45. The reviewer must be independent of the original decision maker and not that person's subordinate wherever feasible, have documented training, and have authority to overturn the decision. Summaries add a ban on AI assistance in the review, a 24-hour response window for phone or mail requests, and delay of the adverse outcome pending review where possible. Deployers must document the reviewer's identity, authority and training, timestamps, evidence reviewed and written justification.
- Commercially reasonable. Human review applies "to the extent commercially reasonable", with a presumption of reasonableness for outcomes such as termination or denial of housing.
- Data access and correction. Separate rights to see the data used and correct inaccuracies.
- Developer information. Reported to include intended uses, known limitations, known inappropriate uses, training data categories and monitoring instructions.
- Chatbots. Age estimation that does not rely only on a user's claim, a persistent visible disclaimer for minors no smaller than the largest text on screen, self-harm protocols, no presenting outputs as licensed professional services, and an annual report to the Attorney General.
One summary reports no small-business exemption in the statute or the rules.
The issues the Attorney General left open
These are the places where a comment can change the outcome, because the Department itself flagged them.
- What "materially influence" means. Two options are on the table. One excludes only factors that are "trifling, trivial, or incidental". The other allows an exemption where the human's independent analysis plays a significantly larger role than the AI output. One firm called the gap between them the most consequential open issue.
- Who is responsible when a vendor runs the tool. The Department acknowledged the act does not explicitly address deployers that do not directly operate the technology, and asked whether vendors should carry obligations or the principals remain responsible. Staffing agencies and recruitment outsourcers raise the same question.
- How much developers must disclose. What detail on testing, training data categories and format.
- What counts as a "basic human need". Housing denial is treated as presumptively requiring review. Other categories, such as utilities, benefits and health care, are not confirmed.
Numbers worksheet (fill this in first)
A comment with numbers is read. A comment without them is skimmed. Collect these before you write.
Our organization
- Name, headcount, industry: ______
- Role: deployer / developer / both: ______
- Tools in scope (category, vendor, decision type): ______
Volume
- Consequential decisions per year affecting Colorado residents: ______
- Of those, adverse outcomes per year: ______
- Expected human review requests per year (our estimate and basis): ______
Cost
- Hours per human review under the proposed standard: ______
- Staff needed (name roles) and annual cost: ______
- Cost to rebuild notices (12-point, two channels, scores, sources): ______
- Cost or delay if our vendor cannot supply principal reasons: ______
Effect
- Hiring or service delay from a 45-day review window: ______
- Tools we would stop using if the rule is adopted as written: ______
If you cannot estimate a number, say so in the letter and say why. An honest "we cannot yet estimate this because our vendor has not told us what data it uses" is itself useful information for the Department.

10. CLOSING
Thank you for considering these comments. We are available to discuss
them and can provide further information on request.
[Name, title, organization, contact]
Rules for writing it well
- One issue per heading, and cite the rule number. The reader is sorting hundreds of comments by section.
- Say what you want changed, in words the Department could adopt. "This is burdensome" gets noted. "Define 'wherever feasible' as follows" can be used.
- Use your numbers. The worksheet exists for this.
- Support what you support. A comment that also endorses the parts you accept is more credible than a list of objections.
- Do not claim what you cannot back up. If you have not read the full text of a rule, say you are relying on a summary.
- Keep it short. Two to four pages is plenty.
- Assume it is public. Leave out customer data, vendor pricing under NDA and anything confidential. Consider filing through a trade association or coalition so operational details are not tied to a single company.
A 3-minute hearing script
The hearing is October 26 at 10 a.m. in Denver, with a remote option. Check the portal or the Department's notice for how to sign up to speak and for time limits. Read it aloud once before you go.
Good morning. My name is [name] and I am [title] at [company], a
[industry] business with [N] employees, [N] in Colorado.
We use [tool category] to [decision type], roughly [N] times a year for
Colorado residents. We support the goal of telling people why an
automated tool affected a decision about them.
I want to raise [one or two] issues.
First, [Issue, with rule number]. As written, [effect on us, with one
number]. We ask the Department to [specific change].
Second, [Issue]. [One sentence of evidence.] We ask the Department to
[specific change].
We have submitted written comments with the detail. Thank you for the
opportunity to speak, and I am happy to answer questions.
Stay under three minutes by speaking to two issues, not six. Everything else goes in the written letter.
Final checklist before you file
- Rule numbers checked against the current version on coag.gov/ai
- Every number in the worksheet has a basis you can state
- Nothing confidential in the text or attachments
- Counsel has read it
- Filed before 11:59 PM on October 26, 2026, with the confirmation saved
- Hearing sign-up done if you plan to speak
What we could not verify
- We did not read the proposed rules themselves, only law firm and compliance summaries. The summaries agree on the main points but differ on a few details, including the earlier comment cut-off and the hearing address.
- We could not confirm whether the revised draft expected in late September was posted, so the rule numbers may have changed.
- We could not load the Attorney General's comment form page. The portal address comes from secondary sources, so confirm it at coag.gov/ai.
- The "no small-business exemption" statement comes from one summary.
- Nothing here predicts what the Department will do with any comment.
