Projects are workspaces for research that should stay together.
If a normal chat is a single conversation, a project is the container around a whole body of work: related chats, shared instructions, uploaded files, and saved papers.
A project can hold:
This makes projects the right place for multi-step tasks like diligence, market research, client work, and paper development.
The create dialog asks for:
Custom instructions are not part of the create dialog. After the project exists, open it and use the Custom Instructions tab to add standing guidance for all chats in that project.
How many projects you can create, and how many reference files each project may hold, depends on your plan. Corbis reads those limits from your subscription entitlements and surfaces the current caps in the project UI (for example on the projects list and in the Files area).
Some tiers treat reference files as unlimited internally (the product uses a sentinel value of -1 for “no numeric cap”). When that applies, the interface shows unlimited instead of a number.
If you are already at your project count limit, you stay on the same screen: the app shows a Project limit reached notice with an explanation and a Go to Billing link to Settings → Billing (/settings?tab=billing). The create flow on the list page can show the same kind of alert inside the dialog when creation fails for that reason—again, a prompt and link, not an automatic redirect.
Each chat can be linked to one project or to no project.
Behind the scenes, that choice is saved on the chat: the app sends an update to the server so the chat’s stored projectId matches what you selected. The next time you open that chat, it loads with the same project association until you change it again.
Once the conversation has at least one message (from you or the assistant), you cannot move that same thread to a different project from the header menu. That rule keeps long transcripts tied to one project’s context.
If you try to switch anyway, Corbis explains that you need a new chat and offers Start new chat. Confirming opens a fresh chat; your newly chosen project is pre-selected there so you can continue under the right workspace without reassigning manually.
On a brand-new chat—with no messages yet—you can change or clear the project from the header as many times as you need before the first send.
Open a project from Projects in the sidebar, then use the tabs across the top.
Lists chats that belong to this project. New chats you start with this project selected appear here over time.
Use this tab when every chat in the project should follow the same standing guidance. These instructions are applied together with Corbis’s default system behavior for chats in this project.
Examples:
Upload reference files that should be available across the project. How many files you can store depends on your plan; the project UI shows your effective cap (including unlimited, when your tier allows it).
Saved academic papers live here. This is useful when you want to keep the most relevant sources attached to the project instead of hunting for them again later. There is no separate “papers quota” in entitlements—the emphasis is on useful curation, not an arbitrary paper count cap.
The project Guide tab explains how project context works and how to use the available space well.
Use a project when:
Do not force everything into projects. For one-off questions, normal chat is usually faster.
