project cards vs chat threads

Project cards vs chat threads is a fair question, because a chat thread is how most AI assisted work actually starts and for small jobs it is entirely adequate. You describe a problem, the agent responds, you iterate, you move on. Threads are fast, flexible and need no setup. A card is a different instrument: a structured record with an identifier, a priority, a status, dependencies, a scope and completion criteria, that exists independently of any one conversation. The two are not rivals so much as tools for different horizons. A thread is good for thinking and exploring. A card is good for committing to an outcome, handing it to an agent, tracking it and reviewing the result later. This page compares them on the axes that matter and says where Liquid Brain places the boundary between them.

Where chat threads are the right tool

Use a thread when the work is exploratory, short lived or genuinely conversational. Asking an agent to explain an unfamiliar module, sketching three approaches before choosing one, debugging with back and forth observations, drafting a function you will rewrite anyway: these do not need an identifier or a status. Imposing a card on them is overhead, and overhead discourages the casual questions that make agents useful. Threads also capture reasoning that never needs to be formalized. The test is whether anyone, including you next month, will need to find or rely on the result. If the answer is no, a thread is fine, and discarding it is fine. Resist the urge to track everything. A project where every question has a ticket is as unhealthy as one where nothing does.

Where threads stop and cards take over

A thread has no state, no owner, no dependencies and no search by purpose. It cannot tell you the work is blocked or waiting for review. It is also tied to the tool that holds it, so a conversation in one agent is invisible to another. As soon as a result needs to be trusted, scheduled, revisited or handed to someone else, the missing structure hurts. A card holds what a thread cannot: a stable identifier you can cite, a status that says what is allowed to happen next, a scope that says where changes belong, and criteria that say how you will know it is finished. The practical pattern is to let the thread produce the thinking and then promote the conclusion into a card. The thread is the workshop, and the card is the work order. Promote when the outcome has to survive the session.

How Liquid Brain separates the two

In Liquid Brain the card is the project record. You create cards, edit their details and track them through the board [C1a], and find them by ID, title, domain, scope or artifact [N01]. Saved project views and a switch between Kanban and List make cards easy to find again [N01]. A card can open a Claude or Codex session, so the conversation happens attached to the work and not the other way round [C1b]. Creating a card starts neither an agent nor a schedule. A scheduled task is separate, an explicit request with readiness and authority checks [C1c]. Bounded task context carries dependencies and notes into the session, with omissions disclosed [N11], and the recorded outcome comes back to the card [C4]. The thread remains where the agent talks. The card remains where the project remembers.

QUESTIONS

Should I make a card for every AI chat?

No. Use threads for exploration and quick questions. Make a card when the result must survive the session: when it will be scheduled, reviewed, depended on or handed to someone. Over tracking is its own failure, because it makes people stop using the system.

Does creating a card start an AI agent?

Not in Liquid Brain. Creating a card records the work only. An agent starts when you open a session from the card [C1b] or when an explicit scheduled task runs after its readiness and authority checks [C1c]. Saving a card or adding planning dates does not by itself authorize execution.

Can a chat thread replace a project board for AI work?

For a single short task, yes. For several concurrent tasks it breaks down, because threads carry no status, dependencies or search by purpose. A board of cards with states fills that gap, and Liquid Brain tracks work through nine states [C2].
