SUEDESCAN

We scanned Calendly. Its challenger is cited just as often.

Calendly did not commission this and is not a client. It is the demonstration teardown: the same capture we run before any engagement, pointed at a company everyone knows. Six buyer prompts, repeated runs, 12 scored samples, every raw answer kept on disk. Calendly still owns its name. The answers underneath it are already being fed by someone else.

Share of voice in the scheduling category.

Every brand named across the 12 answers. Calendly holds the top line, which is what you would expect from the brand that named the category. The finding is the second line: an answer engine now treats Cal.com as Calendly's equal, and five smaller rivals ride along in a third to half of all answers.

Square Appointments, Zoho Bookings, YouCanBookMe and Doodle also appeared, each in one or two answers. Brand matching is by name or domain, case-insensitive, scored from the raw answer text.

The six buyer prompts, and who each one fed.

Each prompt was asked twice in separate sessions. The number after each brand is how many of the two answers named it. The row to sit with is the third one: a free-tier prompt Calendly should own outright, where it appeared in one answer of two while its challenger took both.

The sharpest loss in the set: Calendly has a free tier and a Stripe integration, so "free booking page that connects to Google Calendar and Stripe" is its own product described back to it. The engine handed that prompt to Cal.com and Setmore.

The domains feeding the answers.

Engines assemble answers from sources, and the sources are where this category is actually being decided. cal.com is the most-cited domain in the sample, ahead of calendly.com itself. Two aggregator-style domains most buyers have never heard of are seeding answers too.

Reading for Calendly: the answers are not being fed primarily by calendly.com. An open-source rival whose whole strategy is machine-readable documentation is out-citing the incumbent on the incumbent's own category prompts.

Caveats, stated before you ask.

Calendly did not ask for this

This teardown is unaffiliated and uncommissioned. Brand names appear because the engines named them; nothing here implies endorsement by, or any relationship with, Calendly or any brand listed. It exists to show the exact capture a serious company gets before we ever discuss scope, run against a company big enough that nobody can call the result cherry-picked.

Demonstration scale, one engine

Twelve samples from one engine, Claude with web search on, captured 2026-08-19 with zero engine failures. That is demonstration scale, stated plainly. An engagement capture runs more prompts, more repeats, and captures ChatGPT, Perplexity and Gemini directly. Same scoring discipline as the self-scan: raw answers kept, empty answers scored as engine failures, never as misses.

Point in time, like every number on this site

LLM answers are non-deterministic and change between runs and over time. Every figure is a timestamped snapshot from the dated run its plate names. Method, scoring rules, and why an empty answer never counts as a miss: the methodology page.

This is the view your buyers already have of you.

We run this capture on your company and your category before we ever talk scope. Suede Labs works on retainer with a small number of serious companies: SEO, AEO, PR, visibility and reputation, as one engagement. If that is you, write to us.
