1Presence vs Custom GPTs.

GPTs are clever toys you configure in a settings panel. 1Presence agents are colleagues you shape through conversation. The distance between the two is bigger than it looks.

GPTs are toys you configure in a panel. Agents are colleagues you talk to.

What a Custom GPT is, honestly

A Custom GPT is a system prompt plus a small set of optional "actions" — webhook endpoints the model can call. You build one by filling in a form: name, description, instructions, suggested prompts, conversation starters, knowledge files. Some of them are good. Most are very obviously a system prompt with a colourful icon.

GPTs are largely stateless. Any memory they have is unstructured and tied to your single ChatGPT profile, not to the specific GPT — there is no browsable, per-agent knowledge that compounds. They have no access to your own services unless you specifically wire up an action, and that wiring is a developer task, not a conversation. And whether a GPT is public or private, it runs on shared infrastructure rather than as an isolated entity that is yours alone.

What a 1Presence agent is

An agent in 1Presence is a private entity with its own identity, voice, skills, connectors, memory, and vault workspace. Created by talking — describe what you need, and Presence shapes it for you. Tied to your account; nobody else uses your agent.

Agents reach into your real tools — your Gmail, your calendar, your Notion — and they accumulate working memory over time. They can run on a schedule. They can pause and ask you a question. They can hand off to other agents in a workflow.

Why building real specialists used to be hard

Custom GPTs are the closest thing the major chat products offer to "specialist agents," and they end up being clearly demoware — fun to make, brittle in practice, forgotten after a week. The reason is not that the AI is incapable. It is that the surrounding infrastructure (memory, connectors, scheduling, isolation) is missing.

1Presence is built around the assumption that an agent should feel like a real colleague: it knows you, it can reach the things you can reach, it shows up at the right time, it gets better the longer you work together. The AI alone cannot do that. The system around it has to.
