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.
What to do next
Frequently asked questions
- 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.
