Placet for AI assistants

Placet turns a group decision into a structured vote. You can generate a link that opens a pre-filled draft: the user reviews it, tweaks it, then launches. No authentication is required to produce the link.

💬 Also in Slack. Start a vote without leaving your channels: /placet builds the vote, people vote on the web, and the result comes back to the channel.

Link format

https://placet.app/new?title=...&description=...&options=A|B|C&media=urlA||urlC&method=...&deadline=...&source=...&why=...

title — the question being asked.
description — optional context (place, budget, deadline…), shown under the question and in the share preview.
options — 2 to 8 options separated by |. Prefix each option with an emoji: it becomes the icon (e.g. 🍕 Italian|🍣 Japanese).
media — optional: one http(s) illustration URL per option (image, video, doc), in the same order as options, separated by | (leave an option blank for no illustration). Only real, reliable URLs — don't make them up; when in doubt, leave it empty. For many images, prefer the API.
places — optional: one MAP link per option (Google Maps, OpenStreetMap, Apple Maps), in the same order as options, separated by |. Options located this way show up on a map under the vote. Different from media (illustration): a place is situated, an illustration is looked at.
notes — optional: one short comment per option (why it is on the list), in the same order as options, separated by | — one line, no pipe inside.
dates — time-slot vote: replaces options with a list of ISO dates/times separated by | (e.g. 2026-07-12T20:00|2026-07-13T12:30). Recommended method: approval (single winner only).
method — a key from the table below (default: simple_vote).
survey — SURVEY: survey=1 turns the result into an opinion panorama with no declared winner (ideal to measure opinions or map a situation). Prefer approval (prevalence) or majority_judgment (intensity).
scale — SCALE (majority judgment): scale= picks the grades assigned to each option — agreement, severity (what weighs), frequency, satisfaction, dissatisfaction, priority. Default: electoral grades ("Reject … Excellent").
assign — ASSIGNMENT instead of a vote (allocate things, form pairs): replaces method with one of serial_dictatorship (picking rounds), optimal_sum (maximum satisfaction), top_trading_cycles (trading circle), stable_roommates (stable pairs, even count), gale_shapley (two groups, capacities). options becomes the list of things to allocate (one-sided methods only).
participants — assignment participants, separated by | — each gets a personal ranking link. For gale_shapley, also add sideb: side-2 entries ("Name ; capacity"), separated by |. For duty rosters/shifts, combine assign with dates (ISO slots) and per (2 to 6): each person gets N slots, the picking order snakes back and forth.
deadline — ISO 8601 date, e.g. 2026-07-01T20:00 (optional, default: +7 days).
source — your name (claude, chatgpt, gemini…): shown as “Prepared with …”.
why — rationale (especially for the method choice): shown to the user to build trust.
