59% of first choices, clear leader.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison. How the floor is measured
Google Calendar Appointment Scheduling is made by Google, whose model Gemini 3.5 Flash is in the set. On the four share prompts that model made it the first choice zero times of 4; the other thirteen models zero times of 52. Lab treatment is defined on the method page; the row is marked, not excluded.
“still the default for one-off meeting links, but the free tier is very tight... Only one free link, Fewer free calendars, Customization is limited.” Muse Glimmer 30B, negative prompt
“Tools to Skip... Massive overkill for a small business.” DeepSeek V4 Flash, paraphrase prompt
“Avoid using Doodle’s free or basic tiers for any B2B or external client communications.” Gemini 3.5 Flash, negative prompt
“**Why avoid?** No free plan (just a 7-day trial), email-only support, and costs start higher” Grok 4.1 Fast, negative prompt
74 of 84 answers in this category came back with a source list, from 14 of 14 models: citations where the model returns them, or the search results it consulted. 969 links across 205 sites, every framing counted. Ranked by the number of answers carrying the site or page. None of the 252 answers across every segment cited this index's own page for the category.
The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.
