The short answer

Name the limits where they matter: a short "good at / not yet" note at first use, and a plain "I can't do that, but here's what I can" when a request crosses the line. A blanket disclaimer does neither.

Original mobile concept in charcoal and bright yellow-green. A notes assistant has processed a 32-minute meeting called Weekly sync. A first-use card titled Before you start lists Good at: summaries, action items, finding what was said; Not yet: booking meetings, telling speakers apart; Check: names and numbers. The user asks: Book a follow-up for Friday. The assistant replies, marked Not yet, Outside what I can do: I can't book meetings yet. I can draft the invite with the action items, for you to send, with buttons Draft invite and Open my calendar. Beside the phone, a dithered block of solid yellow-green cubes sits inside a frame; beyond the frame the cubes turn to outlines and scatter. Text: Illustrative concept. Good at. Not yet. Then a next step at the edge.

Illustrative concept, not client work or measured results.

A disclaimer is not an expectation

Amershi and colleagues distilled over 150 AI design recommendations into 18 guidelines. The first two: "Make clear what the system can do" and "Make clear how well the system can do what it can do." When 49 HCI practitioners checked 20 popular AI products against them, the authors found the second relevant but not widely implemented.

These are tested heuristics, not proof that a capabilities note improves outcomes. Still, "AI may make mistakes" meets neither. It doesn't say what the feature does or where it stops.

Say it at first use, and again at the edge

Google PAIR advises being "up-front about what your product can and can't do the first time the user interacts with it." Otherwise, people "may find the boundaries of the system by experimenting in ways it isn't prepared to respond to." When the AI can't complete a request, avoid dead ends: give people a way to finish the task manually.

In this illustrative concept, a meeting-notes assistant opens with a short card: what it's good at, what it can't do yet, and what to double-check. Asked to book a follow-up, it says it can't, and offers to draft the invite instead. For the "how well" half, see Turn AI confidence into a next step.

Illustrative concept: Two moments to say it. 1, at first use: Good at, summaries and action items; Not yet, booking meetings; Check, names and numbers. 2, at the edge: I can't book meetings yet, followed by a Draft invite button instead of a dead end. Beside it, the assistant screen after Draft invite: an invite draft titled Follow-up: Weekly sync, marked You send, with When: Friday, you pick a time; Includes: 3 action items; Guests: add from your calendar; buttons Open in calendar and Edit draft; and a note: Drafted from this meeting, nothing sent.

Before you ship the disclaimer

Ask three questions. After first use, could someone name one thing the feature can't do? Does every out-of-scope request end in a next step? Have you actually seen the limits you list in testing?
