Core concepts
The handful of entities — BuckyAssist, projects, parcels, site options, zoning, feasibility, and services — that show up across every part of Bucky.
A few concepts appear across every part of Bucky. Learn these once and the rest of the docs — the platform, the API, and the MCP tools — will read naturally.
BuckyAssist and Project Scout
BuckyAssist is Bucky's AI assistant — ask in plain language in chat. On the Projects map, the same assistant appears as Project Scout in the map dock, focused on exploring blocks, comparing site options, and assessing development potential. See Site exploration and Prompting BuckyAssist.
Project
A project is the container for a piece of planning work. It ties together the parcel you're studying, the analysis you run against it, and the services you engage. Most workflows start by creating or opening a project.
Parcel
A parcel is a specific piece of land. It carries the geographic and physical facts Bucky reasons about — boundaries, lot dimensions, and the identifiers a jurisdiction uses to refer to it. A parcel is the anchor for zoning and feasibility: almost every question ("what can I build?", "does it pencil?") resolves against a parcel.
Zoning
Zoning is the set of rules a jurisdiction places on a parcel — what uses are allowed and the limits that shape what can be built. Bucky interprets the applicable zoning for a parcel so you can see the constraints in plain terms instead of reading a bylaw cover to cover.
Feasibility
Feasibility is the analysis of whether a project is viable on a given parcel under its zoning. It's where the physical facts and the rules meet the numbers, helping you decide whether an idea is worth pursuing before you commit time and money.
Site option
A site option is a named candidate site on a project — often created after map exploration with Project Scout. Before you save a project, exploration candidates appear as unsaved site options on the map; Review & create or Save option makes them durable inside the project.
Services
Services are the people and providers who do the work — builders, designers, and architects — discoverable through Bucky's marketplace. Once a project has a direction, services are how you connect it to the right team.
How they fit together
The through-line
Use Project Scout on the map to explore land and compare site options. A project studies a parcel. The parcel's zoning defines what's allowed, feasibility tests whether it works, and services connect the project to the people who build it.
Each concept has a deeper home in the Platform section. For map and chat prompts, see Prompting BuckyAssist. When you're ready to do something concrete, head to the quickstart.
