# MatterOS vs ChatGPT: structured matter records or an AI chat?

ChatGPT is a general AI assistant for drafting, summarising and thinking aloud. It is not a system of record: it does not hold your matters, deadlines, time and evidence in a structured, reviewable way. MatterOS is the structure; an AI chat is a tool you use on top of it. The two work best together, with you checking every output.

## Key takeaways

- A chat conversation is not a matter file; records need owners, dates and links.
- AI works better when pointed at structured facts than at a pile of pasted text.
- Never paste confidential client information into any tool until you have checked its terms and your duties.
- You remain responsible for everything an AI tool produces.

## Are they competitors?

Not really. They do different jobs. An AI chat generates and transforms text. A matter system records what is happening in each case: parties, actions, deadlines, time, documents and research, each linked to the matter.

Asking which one to choose is a bit like asking whether to use a pen or a filing cabinet. The more useful question is what happens to the output of the chat.


## Why a chat is not a system of record

| Requirement | AI chat on its own | Structured matter system |
| --- | --- | --- |
| Durable, findable record per matter | Conversations scatter and are hard to audit | One record per matter, linked to everything |
| Deadlines with owners | No tracking; it may simply invent a plausible date | Each deadline is a record with an owner and a due date |
| Reliable facts | Can produce confident errors | Holds only what you entered |
| Review and supervision | Output is not tied to a reviewer | Fields can mark who checked what |
| Handover | Context lives in a chat history | Another lawyer opens the matter and sees the state |

Generative models can state wrong things fluently. Treat every output as a draft that needs your verification, particularly law, citations and dates.


## How the two work together

1. Record first: Keep facts, actions and documents in the matter system as the source of truth.
2. Decide what may leave: Check your tool's terms and your professional duties before sending any client information to an AI service; redact where needed.
3. Use AI on a narrow task: Summarise a long note, draft a client update, or build a checklist, using the prompts you have prepared.
4. Verify and file: Check the output against the record, edit it, and save the final version back to the matter.

MatterOS includes a prompt pack for these tasks. It is a set of prompts you copy into the AI tool of your choice; MatterOS does not itself run an AI model.

## FAQ

### Can ChatGPT replace practice management software?

No. It does not provide structured, reviewable records of matters, deadlines and time. It can assist with drafting inside a proper system.

### Does MatterOS use ChatGPT?

No. MatterOS is a Notion template. It includes prompts you can use in an AI tool you choose.

### Is it safe to paste client details into ChatGPT?

That depends on the tool's terms, settings and your professional obligations. Check them and your bar guidance, and minimise or redact information.

### Can ChatGPT track my deadlines?

You should not rely on it to. Record deadlines in a system with owners and dates, calculated from the applicable rules.

### Do I still need to check AI output?

Yes, always. You remain responsible for the work.
