AI built into practice management software vs an Outlook add-in: how they fit together
AI built into practice management software mostly works from what is saved in the matter, while an Outlook add-in starts from the email in front of you. They fit together when each has a clear job, so check what your practice management software already does in Outlook, then decide which tool drafts client email before you pay for both.

What does AI built into practice management software do?
Mostly it works from what is already saved in the matter, and some products also reach into Outlook. Here is what four vendors say on their own pages, as at 9 November 2026:
- Smokeball. Smokeball's Archie page says Archie works inside your matter to draft, review and answer questions, and summarises a document or matter with meetings, deadlines and tasks linked to the source.
- LEAP. LEAP's legal AI page says Matter AI reads what is saved in the matter, including documents, emails, attachments, scanned PDFs and handwritten notes. It also lists a Generator that produces letters, emails and forms, and AutoTime for logging billable hours.
- Clio. Clio's Australian AI page says Clio Manage can turn court documents into calendar events and tasks, generate draft invoices, and draft letters and client updates based on case activity.
- Actionstep. Actionstep's AI page, written for midsize firms, says its AI passively tracks billable activity across Actionstep, Outlook, Word and other tools, codes time to matters and drafts bill narratives.
Most of these features can see the file, so they are well placed for jobs like summarising a matter before a client call or preparing a bill.
What does an Outlook add-in do differently?
An add-in starts from the email. It is a separate app you open from the message you are reading or writing, which suits the moment before anything has been saved to a matter: a new enquiry, a chaser from the other side, a client who has replied to the wrong thread.
Microsoft's page on using add-ins in Outlook says that in new Outlook you add one from More apps then Add apps, and open it from the ribbon while reading or composing. It also says an add-in might send data to its own service, but only to complete the task you asked for, and that most add-ins only have access to the email you are working in. Microsoft also says you are asked for consent the first time an add-in needs your data, so if one works across the whole inbox, check what it asks for.
Add-ins vary a lot. Some are general email tools and some are built for law firms.
Do I still need an Outlook add-in if my practice management software has AI?
Maybe not, and it is worth checking before you buy one. Smokeball's page says Archie in Outlook summarises email threads and drafts responses pulling from the matter, so a Smokeball firm should try that first and see what is left over. Our guide to AI tools that work with Smokeball goes further on this.
For any other system, ask your vendor three plain questions:
- Can your AI read and draft replies to an email that hasn't been saved to a matter yet?
- Does it work inside Outlook, or do we go to your software to use it?
- Which of these features are on our current plan?
If the answers leave the inbox uncovered, that is the gap an add-in fills. If you are also weighing up Microsoft's own option, see Microsoft Copilot in Outlook vs a legal AI add-in.
How do practice management AI and an Outlook add-in work together in a normal week?
Give each tool its own jobs. One way to split them at a small firm:
- Add-in: sorting the morning inbox, drafting replies to the emails that came in overnight, and catching the settlement email that needs an answer today.
- Practice management AI: summarising the matter before a client call, working through documents already on file, and preparing bills.
- Whichever has the better link to your matters: filing the email and recording the time. Pick one, so nothing is filed or billed twice.
The trap is overlap. If both tools draft replies to clients, someone ends up comparing two drafts of the same family law update, and the saving is gone. Write the split down, even in one line in your procedures, and tell the whole office. If you want a rough figure for what unrecorded email time costs you, try the unbilled time calculator.
What should we check before adding an Outlook add-in?
Two things, and your IT provider can help with both. First, who installs it. Microsoft's page on deploying add-ins in the Microsoft 365 admin center says an admin can deploy one from Settings then Integrated apps, to everyone, to specific users or groups, or just to themselves. Rolling it out to one person first is a sensible test.
Second, where the data goes. Ask the add-in vendor in writing where the app is hosted, where the AI processing happens, whether anything is kept there, and whether your correspondence is used to train AI models. Ask your practice management vendor the same questions, so you can compare like with like. If you use AI on documents filed in court, see our court AI rules tracker.
How to choose between practice management AI and an Outlook add-in: a checklist
- List the three email and matter jobs that take most of your week.
- Check which of those your practice management software already does, and on which plan.
- Check whether its AI works inside Outlook, or only inside its own software.
- Check whether it handles email not yet saved to a matter.
- Only then look at add-ins, for the jobs left over.
- Check whether the add-in connects to your practice management system, or leaves filing and time to you.
- Make sure a person approves every draft, filing and time entry.
- Decide which tool drafts client email, and write it down.
- Trial it for a week with one person, then add up the monthly cost of everything you plan to run.
Where does AI Legal Toolbox fit?
AI Legal Toolbox is an Outlook add-in. Its AI paralegal, Nova, triages the inbox, drafts replies into your drafts folder (it has no send function), reviews contracts and documents, and with Smokeball files emails and records time after you confirm. Smokeball is the practice management system it connects to. It works without one, minus filing and time recording, so firms on other systems would keep filing and time where they are now. It is hosted in Sydney, with AI text processing by OpenAI in the United States, not retained there. It starts with a 7 day free trial (card needed, nothing charged until day 8), then $149 AUD per practitioner per month including GST. See the facts page.

Questions practitioners ask
Can I use AI in my practice management software and an Outlook add-in at the same time?
Yes, they are separate tools. Decide which one drafts client email and which one files and records time, so the work isn't done twice.
Does Smokeball's Archie work in Outlook?
Smokeball's Archie page says Archie in Outlook summarises email threads and drafts responses pulling from the matter, and that you can adjust the tone, length and style before you send.
Who installs an Outlook add-in at a small firm?
Either a user or an admin. Microsoft says some add-ins are installed by your email administrator and others you can install yourself from the store, and that an admin can deploy one to everyone or to specific people from the Microsoft 365 admin center.
