Inline AI Verified by Lawyers: Honest Review After One Month of Use

The legal industry is increasingly interested in automating legal tasks.

In particular, an increasing number of lawyers are comparing various AI tools to see how beneficial specialized legal AI tools really are. Yet, there are many questions like 'Is it really practical for actual tasks?' and 'Is security assured?'

To address these curiosities, we met with the lead attorney of a law office who used Inline AI in their practice for a month, sharing firsthand experiences and feedback on using legal AI.

Interviewee Introduction

Attorney A (Anonymity requested by the attorney, hereafter)

  • Experience: Former prosecutor, current law office operator

  • Office size: 3 employees, handling approximately 200 cases annually

  • Specialization: Civil and family litigation, especially focusing on family (divorce)

  • Inline AI usage period: One-month intensive testing


“I adopted it because my biggest security concerns were addressed”


Q. What prompted you to decide to adopt Inline AI?

Attorney A: "Previously, I was using the free version of ChatGPT. However, Inline AI reached out and proposed testing their dedicated legal AI.

I was curious about AI and thought it was worth trying if it could enhance work efficiency."

Q. What were your concerns before adoption?

Attorney A: "Security issues were my main concern. I was worried whether our office’s legal documents might be leaked externally or shared with other firms, and since AI involves learning, whether our created documents might aid competitors... These were my concerns.

I also thought that if it became commonplace among the public, it could be detrimental to us commercially, not to mention if the headquarters could see everything we were doing."

Q. You had many security concerns. How did you resolve them?

Attorney A: "I gained trust only after confirming that even Inline’s headquarters cannot see how users are using the service.

Additionally, since it operates locally, it was reassuring to find out it offers better security than ChatGPT."

“A task that used to take five hours now gets done in one!”


Q. How did you test Inline AI?

Attorney A: "I conducted a thorough test over one month. Based on actual client information, I prepared pleadings, complaints, answers, and certificates of notice rather exhaustively. I personally drafted around 10 to 15 documents, and including the staff, close to 15-20 documents were prepared. By case standard, it was 20, and in terms of documents, we tested quite a lot."


Q. On what criteria did you evaluate?

“Logical construction of contents, natural flow of context, and logical coherence were evaluated, and it was very good.”

Attorney A: "Based on my experience of reviewing many documents for a long time, I established several criteria.

First, logical construction of contents. I observed how logically it organized content when not specified.

Second, whether the flow of context was natural.

Third, checked for logical coherence.

When I sent it to the client without much revision, they were notably satisfied."


Q. What was the reaction of your staff?

Attorney A: "Everyone was positive. Especially, many were 'astonished'. They didn't expect AI to write so well beyond their initial expectations."

Q. Share detailed practical experiences for individual tasks.
How was 'fact arrangement' deemed crucial in legal documents?

Attorney A: "I saw the most surprising effect in this area. I frequently use it, and when clients give long fact accounts, I ask them to summarize it. I compress the factual situation and re-utilize it for documents.

It’s also used in drafting criminal complaints; when you request it to organize by requirement, it comes out really cleanly."


Q. Specifically, how much did you reduce your time?

Attorney A: "A task that used to take five hours reduced to one hour. That's an 80% time reduction."


Q. Were there any points you found lacking?

Attorney A: "Occasionally issues arise when there are too many characters involved. If there are too many people like A, B, C, AI can get confused, but this was resolved by pre-setting relationships between characters."

“It found parts lacking in the legal requirements of the opponent’s complaint.”

Q. How was your experience in drafting complaints?

Attorney A: "It was most useful when inputting the opponent’s complaint verbatim and asking to draft an answer advantageous from the defendant's perspective.

Amazing was that Inline AI accurately identified legal parts, automatically finding sections lacking in legal requirements in the opponent’s complaint."

Q. How was writing certificates of notice?

Attorney A

: "I tried writing a certificate of notice once and found that the function that organizes roughly written content into a table was useful.


Especially convenient is that even if there were typos or rough language, Inline AI accurately understood the intent."


Q. What changes occurred in your work before and after adoption?

Attorney A: "I utilized it extensively to the point it was dizzying, and it felt like a new world. I realize 'I was a frog in a well.'

To specify the changes, in civil/family cases, previously drafting, revising, and filing took 3 to 5 days, but now with Inline AI, it's been reduced to 3 days: one day for draft, one day for revision, and one day for filing."


“AI that auto-drafts complaints in judges’ favored formats”

Q. Is it difficult to work without Inline AI now?

Attorney A: "It would be quite inconvenient. If it disappears, I'd certainly find a service that is equivalent."


Q. Did you face any difficulties during learning?

Attorney A: "Despite being almost computer illiterate, I didn't face significant difficulty. However, the crucial part is knowing the context and points of the case to correctly utilize Inline AI. It holds no meaning if you don’t understand the case."


Q. Which tasks do you trust the most?

Attorney A: "I highly trust it for content arrangement. It performs really well in this area, which is satisfactory."


Q. Could you share specific use cases?

Attorney A: "There are a few memorable ones.

While doing complaints drafting, Inline AI automatically adds subtitles, which is very useful as judges appear to focus on subtitles.

When receiving abundant materials, the summarizing and opposing-party explanation features were notably helpful.

Unlike ChatGPT, Inline AI improves document readability substantially by effectively capturing subtitles and keywords."

“As document processing time decreases, sales increase”

Q. What do you think about the return on investment?

Attorney A: "By the second day of usage, I felt I had already recouped my investment.

Interestingly, there's a change in fees. Post using Inline AI, I inadvertently lower fees. For simple complaints, I used to charge at least 1.5 million KRW, but since tasks get done in an hour when they used to take five, I unconsciously lowered it to 1 million KRW. Consequently, people who previously didn't hire now do, thus increasing revenue significantly given the time efficiency."


Q. Is there anything you found particularly satisfying?

Attorney A: "I'm especially satisfied that the content comes out adhering to the formats required by the court.

While AI's necessity in criminal aspects might be lower, it's extremely useful in civil or family litigation cases."


Q. What's the main reason you continue using it?

Attorney A: "Time savings are the main reason, and it could lead to revenue growth.

Moreover, with Inline AI, I've gained confidence that even complex cases can be handled. Previously, I only took on cases I could manage, but now I do not highly consider difficulty."


Q. Do you intend to recommend it to other attorneys?

Attorney A: "No intent to recommend. If fellow attorneys use it, competition might weaken! (laughs)"
