How to Record LINE Calls in 2026: 5 Methods and Legal Considerations

"The client mentioned the price three times and two delivery dates during the LINE call, but after hanging up, I only remembered the last sentence." This is a situation almost everyone who uses LINE for business has experienced. Unfortunately, the official LINE app still doesn't have built-in call recording, so you have to figure it out yourself: some use screen recording, some integrate calls into system recording, and some just pull out a voice recorder. This article compiles 5 currently viable methods, and also clarifies speaker settings, file sizes, and legal considerations.

Why Do You Need to Record LINE Calls?

LINE is the most common communication tool in Taiwan. Work-related quotes, delivery dates, and requirement changes are often discussed in a single voice call, but afterward, there's no text record to verify. The value of call recording isn't just "keeping evidence"—more often, it's about organizing to-dos after the call, reporting to your supervisor, or adding the client's requirements to documents. The problem is: recording is just the first step; the real time-consuming part is listening and typing. The difference between the 5 solutions below lies in "how much work is left after recording."

Solution 1 | Tinrec – The Most Complete AI Recording Assistant

Tinrec is an AI meeting notes and collaboration tool for individuals and teams. Its focus isn't just recording audio, but turning calls and meetings into searchable, queryable, and reusable data.

• Record and transcribe computer calls on the fly: The desktop version captures system audio to record online calls and meetings without inviting a bot. If you use LINE on your computer for business, you can generate a transcript in real-time during the call.
• Upload recorded files for organization: Videos from phone screen recordings or audio files from voice recorders can be uploaded and transcribed, automatically generating summaries, chapters, key points, and to-dos, saving the most time-consuming listening and typing.
• Ask follow-up questions about call content: After transcription, you can use AI Q&A about the content, e.g., "What concerns did the client mention?" You can also export to documents, reports, tables, or to Notion, Google Docs, etc.
• Team version keeps data within the team: The team version is a separate team space where data belongs to the team. You can manage members, roles, and seats; when a member leaves or loses a seat, resources can be transferred to other active members. First-time eligible users get a 7-day trial (1 free seat, 300 minutes shared team quota); monthly team plan is USD 29.80 per paid seat per month, annual is USD 199 per paid seat per year (about USD 16.58 per month).

Personal plans include free, weekly, Pro monthly, and Pro annual. If you only occasionally organize a call, start with the free version. Suitable for those who need to organize call content, track to-dos, or share client communication records across a team.

Solution 2 | iPhone Built-in Call Recording – No Extra App Needed

After Apple added call recording to iOS, you can integrate LINE calls into the iPhone's phone recording mechanism, using system recording during the call without extra equipment. Note that different sources have inconsistent reports about the required iOS version (some mention iOS 18, others later versions). Please refer to the actual options on your phone. You must enable speaker so the system can capture both sides; also avoid screen sleep during recording to prevent interruption. Pros: free and easy. Cons: iPhone only, and you still need to organize the recording yourself.

Solution 3 | Built-in Screen Recording – Works on Android and iPhone

This is currently the most popular method: during a call, pull down Control Center and start screen recording to capture both the call screen and audio. Both Android and iPhone have built-in screen recording, but whether it captures the other party's voice depends on brand and OS version—not all phones support it. The key is to enable speaker so the microphone picks up the other party. Video files are much larger than audio; if the system supports "audio only" mode, one hour of call is only a few dozen MB. Free and low barrier, but the output is usually a video file, and you still need to listen and transcribe manually.

Solution 4 | Third-Party Screen Recording / Call Recording Apps

If your phone's built-in screen recording can't capture audio, you can use third-party recording or screen recording apps. When choosing, check three things: whether it can capture both microphone and system audio, whether it indicates speaker requirements, and where recordings are stored (local or cloud). Some apps support auto-sync to Google Drive or Dropbox for backup. Most are subscription-based, with free versions often limited by length or features. Before paying, confirm your call length won't be cut off.

Solution 5 | AI Recording Hardware (PLAUD Note / NotePin)

Representative products are PLAUD's AI recording hardware, designed for portable recording, long battery life, and standalone device form. Official pricing: NotePin USD 159, Note Pro USD 189. Membership plans include Starter (300 minutes/month) and Pro (USD 99.99/year, 1,200 minutes/month). Pros: doesn't occupy your phone, stable recording. Cons: you need to carry an extra device, remember to charge and transfer files, and the hardware itself won't organize content into usable data. Suitable for those who are often on the go and need to record anytime.

How to Choose Among These Solutions?

• Want "someone to organize the recording into transcript, summary, and to-dos" → Tinrec (transcription, AI Q&A, to-do extraction, multi-format export)
• Prefer using LINE on computer for business, don't want a bot in the call → Tinrec desktop (captures system audio, no bot needed)
• Need to share call records with the whole team, manage members, seats, and usage → Tinrec team version (team space, usage analytics, audit logs, audio recycle bin)
• Just occasionally want a record, don't want to pay → Built-in screen recording (remember speaker, check system support)
• Only use iPhone, want the easiest system-level method → iPhone built-in call recording (check version support and speaker limitations)
• Need a physical device for portable recording → PLAUD and other AI recording hardware (still recommend importing to Tinrec for organization)

5 Things to Know Before Recording LINE Calls

1. Check legality first: In Taiwan, if you are a party to the call, recording for evidence or work records is generally fine; but recording to spy on others' privacy is not. When involving third parties or unspecified individuals, it's best to inform and get consent, and companies should follow internal policies.
2. Always enable speaker: Whether system recording or screen recording, without speaker, the microphone won't pick up the other party's voice, and you'll find only your side in the file.
3. Don't let the screen sleep during recording: The system may interrupt recording to save power, causing incomplete files. A more stable approach is to record on computer, e.g., Tinrec desktop captures system audio directly, unaffected by phone sleep.
4. Estimate file size: Pure audio is about a few dozen MB per hour, but with video it increases dramatically. Check your phone's free space before the call.
5. The real work starts after recording: Many people record a lot but never listen. Give files to Tinrec to transcribe and summarize, then use AI Q&A to find details—much faster than replaying. For important content, still verify against the transcript timestamps and original audio.

Conclusion

LINE doesn't have built-in call recording, so the real question isn't "can I record" but "can I use it after recording." Built-in screen recording is fastest and free, but outputs video files; iPhone system call recording is easiest but has version and speaker limitations. If you record LINE calls for work—client requirements, quotes, delivery dates, to-do tracking—then a tool like Tinrec that combines transcription, summary, to-dos, AI Q&A, and team space will save more time than a recording file sitting in your gallery. Try the free version with one of your own calls to experience the difference of "recording directly becoming data."
