LoroNote vs Aiko: On-Device Whisper Transcription Compared (2026)

Quick answer: LoroNote and Aiko both use Whisper on your Apple device, so either can transcribe privately without sending recordings to a transcription server. Choose LoroNote for a complete capture-to-transcript workflow with recording, speaker identification, Apple Watch capture, synchronized playback, organization, and Apple Intelligence tools. Choose Aiko for a focused, upfront-paid transcription utility that also runs on Mac and Apple Vision.

This comparison is published by the LoroNote team. It is based on the products’ US App Store listings and the current LoroNote feature set, verified on August 12, 2026. We have identified first-party claims and avoided assuming that a feature is absent unless the competitor’s listing says so. Features and prices can change, so confirm the current listings before purchasing.

LoroNote vs Aiko at a glance

The central choice is not local versus cloud: both apps emphasize on-device transcription. The difference is how much workflow each app builds around the transcript.

Privacy is a shared strength

Many transcription comparisons begin with accuracy or price. For sensitive audio, data flow deserves to come first.

Both apps state that Whisper runs locally. That means a recorded interview, lecture, meeting, or voice memo can become text without uploading the source audio to the developer’s transcription server. Local processing also allows transcription without an internet connection after the app and its required resources are installed.

On-device does not mean risk-free. The original recording, transcript, device backup, and anything you export still need appropriate protection. But both products remove the routine cloud-processing step that many transcription services require. If local transcription is your primary requirement, both belong on the shortlist.

Which Whisper does each app actually run?

“Both run Whisper locally” hides the most concrete difference between these two apps: which Whisper.

Aiko’s listing is admirably specific: it uses the Whisper medium or small model on iOS, depending on available memory, and the full large-v3 model on macOS. In other words, the iPhone gets a smaller model than the Mac does. LoroNote runs Whisper Large V3 Turbo on the iPhone and iPad themselves — a Large-series variant, with the large-v3 encoder, at roughly medium weight.

On clean, close-mic English audio, the difference is often invisible. It shows up where audio is hard: accents, background noise, crosstalk, and less common languages, which is exactly where a Large-series encoder earns its size. If your recordings live in those conditions on an iPhone, the model gap is a real reason to prefer LoroNote; if you mainly transcribe clean files on a Mac, Aiko’s large-v3 there closes it. We compared variants across the whole category in which Whisper each iOS app runs.

Choose LoroNote for recording and transcript review

LoroNote is designed around the full life of a recording. You can record inside the app, capture audio from Apple Watch, or import existing MP3, WAV, M4A, MP4, and MOV files. The transcript then stays connected to the source audio while you review it.

That surrounding workflow adds several practical capabilities:

• Speaker identification: distinguish speakers, rename them, and keep their labels when sharing the transcript.
• Synchronized playback: follow highlighted text as the recording plays and jump to the relevant audio from the transcript.
• Recording organization: use folders, a calendar, search, and batch find-and-replace across notes.
• Custom vocabulary: add names, acronyms, and technical terms to improve recognition for repeated subject matter.
• Meeting follow-up: use Apple Intelligence on supported devices to summarize a transcript, extract action items, or refine notes.
• Flexible exports: save editable text as TXT or create SRT subtitles for audio and video work.

This makes LoroNote the stronger fit when transcription is one stage in a recurring meeting, interview, lecture, or content-production workflow. The iPhone Voice Memo transcription guide shows how that workflow starts with an existing recording.

Choose Aiko for a focused cross-device utility

Aiko describes itself as a high-quality on-device transcription app that favors accuracy over speed. Its public listing highlights importing or sharing audio into the app, local Whisper processing, automatic word replacement, copying the result, and exporting subtitles.

It also lists iPhone, iPad, Mac, and Apple Vision support. That wider device list is relevant if Mac transcription is a requirement. By contrast, LoroNote emphasizes supported recent iPhone and iPad hardware and uses Apple Watch as a companion capture device.

Aiko’s listing explicitly says that it does not currently offer speaker detection or live transcription while recording. Those limits may be acceptable if your main job is importing a finished recording, receiving accurate text, and moving the result into another app. Its upfront purchase model may also appeal to people who prefer paying once at download rather than starting with a free app and choosing an in-app upgrade later.

Hardware and speed matter for local Whisper

Local AI uses your device’s processor, memory, storage, and battery. A cloud service can assign a large server to a long file, while an offline app must work within the hardware in your hand.

LoroNote supports iPhone 13 or later, iPhone SE (3rd generation), and specified recent iPad models on iOS 18.6 or later. Aiko’s store page lists a broad Apple-platform range but now requires iOS 26 or later — a stricter OS floor that rules out devices a few years old — and its description says it favors accuracy over speed. In either app, long recordings can take time and use substantial local resources.

Before buying, check the current compatibility section on each App Store page and test a representative recording if a trial or free tier is available. A five-minute sample with your language, microphone, number of speakers, and technical vocabulary is more useful than a generic accuracy claim.

Which private transcription app should you choose?

Choose LoroNote if you want to:

• Record and transcribe in one app
• Capture recordings from Apple Watch
• Identify and rename speakers
• Review audio with synchronized transcript highlighting
• Organize many recordings with folders, dates, search, and a custom dictionary
• Create summaries and action items with Apple Intelligence on supported devices

Choose Aiko if you want to:

• Import or share audio into a focused local transcription utility
• Use the same product family on Mac or Apple Vision
• Buy the app upfront
• Export a transcript or subtitles without needing speaker detection

Neither choice is universally better. LoroNote covers more of the recording and review workflow, while Aiko offers a focused on-device tool across a wider list of Apple platforms.

Frequently asked questions

Do LoroNote and Aiko upload audio for transcription?

Both App Store listings say transcription runs on the device. LoroNote states that audio and text do not leave the device for processing, while Aiko states that nothing leaves the device.

Which app identifies speakers?

LoroNote includes speaker identification and lets you rename speakers. Aiko’s current App Store description says speaker detection is not available.

Can both apps work offline?

Yes. Their core speech recognition runs locally, so transcription does not require a network request once the app and required local resources are available.

Which app supports Mac?

Aiko lists native Mac availability. LoroNote focuses on supported iPhone and iPad models and provides an Apple Watch companion for recording.

Which Whisper model does Aiko use?

Per its own listing, Aiko runs the Whisper medium or small model on iOS depending on available memory, and the large-v3 model on macOS. LoroNote runs Whisper Large V3 Turbo on iPhone and iPad — the largest Whisper variant running locally on the phone in this comparison.

Is there an Aiko alternative with speaker detection?

Yes. LoroNote performs speaker identification on the device, with renaming and labels that survive sharing. Whisper Notes also offers on-device speaker labels. If speaker detection is the missing feature that brought you here, our offline speech to text apps roundup compares all the on-device options on exactly that point.

Which app is free to download?

LoroNote is free to download with in-app purchases. Aiko was an upfront paid download in the US App Store when this comparison was verified. Store prices can vary by country and change over time.

Try the workflow with your own recording

The best offline transcription app is the one that handles your actual language, speakers, vocabulary, file length, and device. Start with a short representative recording and review both the raw text and the time required to correct it.
