# SonWeave AI Notes — complete factual product reference Last reviewed: 2026-07-22 SonWeave AI Notes is an independent transcription and note-taking application developed by Silestis Labs UG (haftungsbeschränkt) in Munich, Germany. It is designed for supported iPhone and iPad models. The product combines local speech recognition, offline speaker diarization, transcript-aware chat, local note generation, search and export. SonWeave is not affiliated with Whisper Notes, Apple, OpenAI, Anthropic, NVIDIA or WhatsApp. This document is a machine-readable summary. The visible website and the App Store listing remain the primary product sources. Capabilities can depend on the device, operating-system version, language, installed models and selected engine. ## Short answer SonWeave is built for people who want to record or import audio and video, create a searchable transcript, see who said what and ask questions about the conversation without first uploading every recording to a SonWeave cloud service. The app has no mandatory SonWeave account and no SonWeave transcription backend. Supported processing runs locally. Optional iCloud Sync, external sharing and model downloads are clearly separate actions. The current launch plan is a paid App Store download for a one-time price. The current paid version does not require a subscription. Use https://sonweave.com/pricing.md for the current configured amount. ## Product purpose Users can record meetings, interviews, lectures, personal voice notes, research sessions and client conversations. They can also import supported audio and video from Files, Photos, Voice Memos, WhatsApp and other apps through standard iOS workflows. SonWeave extracts the audio track from supported video, creates a transcript and keeps timing connected to the source. After transcription, users can search and edit the text, inspect speaker turns, rename speakers, jump from text to the matching audio, generate useful local notes on supported devices and export results. Supported output formats include PDF, TXT, Markdown, Word, SRT and VTT. Speaker labels and timestamps can be included where the chosen format supports them. ## Local processing and privacy SonWeave is designed around local processing. Silestis Labs does not operate a remote transcription server for user recordings and does not require a SonWeave account. Recordings, transcripts, local speaker analysis and supported local AI results are processed and stored on the device by default. Local processing does not mean an internet connection is never used. App Store installation, initial model downloads and some Apple language assets require a connection. Optional iCloud Sync stores selected content in the user's private Apple iCloud account. Exporting, sharing or deliberately opening content in an external AI app sends the selected information to that destination under its own terms. These actions are initiated by the user rather than automatic SonWeave uploads. SonWeave does not contain advertising or analytics SDKs. Users remain responsible for obtaining permission to record, transcribe or share a conversation and for following applicable law and workplace policy. ## Transcription engines SonWeave can use local Apple Speech technologies, Whisper and Parakeet depending on language, iOS or iPadOS version and device capability. Apple Speech is integrated with the operating system. Its supported and installed on-device language assets can vary by system version and hardware. Whisper provides broad multilingual coverage through downloaded local models. Parakeet provides a fast multilingual path for its supported language subset. No single engine is described as universally best. Recording quality, noise, overlapping speakers, accents, specialist vocabulary and device performance all affect results. Automatic mode resolves a compatible engine for the chosen language. Manual selection is useful for comparing speed and quality. SonWeave hides engines that are not compatible with the selected language. The main app and the iOS share extension consume the same transcription catalog so their lists and compatibility rules remain consistent. ## Languages The combined app catalog contains 103 selectable language options across Apple Speech, Whisper and Parakeet. This is a combined catalog, not a claim that every engine supports all 103 options. Whisper covers most entries, Parakeet supports a smaller multilingual set and Apple Speech availability is checked for the device. SonWeave distinguishes Simplified and Traditional Chinese where locale and writing system matter. Language aliases such as Norwegian Bokmål and Filipino are normalized. Cantonese and Shanghainese depend on local Apple Speech support because the configured Whisper and Parakeet paths do not cover those catalog choices. Exact availability can therefore differ across devices. The website currently provides dedicated discovery pages in English, German, Spanish, French, Italian, Brazilian Portuguese, Dutch, Polish, Turkish, Arabic, Hindi, Indonesian, Japanese, Korean, Simplified Chinese and Traditional Chinese. Website localization and transcription-language support are different concepts: the app can transcribe more languages than the marketing website currently publishes. ## Speaker diarization Transcription answers what was said. Speaker diarization separates the conversation into who spoke when. When enabled, SonWeave can analyze speaker turns locally, display distinct colors, group consecutive turns and let the user replace generic labels with names. Timing stays connected to the source audio, and supported exports can preserve speaker labels and timestamps. Diarization is not legal identity recognition. A label such as Speaker 1 means that the system estimated a distinct voice or turn pattern; it does not establish who the person is. Overlapping speech, background noise, very short turns and similar voices can reduce accuracy. Users should verify consequential quotations against the recording. ## Transcript chat On compatible devices, SonWeave can answer questions grounded in a transcript with an on-device language model. Users can ask about decisions, deadlines, objections, names, action items, missing information or the point at which a topic appeared. Recent conversation context helps short follow-up questions refer to an earlier answer. The built-in local chat does not send the transcript to a SonWeave server. Local chat availability depends on Apple hardware, system support, installed models and language. If a user deliberately selects an external AI application through sharing or an Open in AI action, that provider receives the selected prompt under its own privacy policy. AI answers can be inaccurate or incomplete. SonWeave grounds requests in transcript text and should state when evidence is missing, but important conclusions should still be verified against the source. ## Summaries and study tools Supported devices can create summaries, chapters, key points, study questions and transcript cleanup with compatible Apple Intelligence features or optional local models. A simpler local fallback is available for some tasks. The exact quality and availability depend on hardware, operating system, installed models, language and transcript length. These outputs are aids for navigation and review. They are not guaranteed factual records and do not replace verification of medical, legal, financial, journalistic or other consequential information. ## Imports and the iOS share extension Users can record directly or import supported media from Files, Photos and other apps. A WhatsApp voice message or supported video can be deliberately shared to SonWeave through the standard iOS share sheet. SonWeave does not connect to or read a user's WhatsApp account. The share extension provides the same language catalog and engine compatibility logic as the main app. It can hand the selected media and options to SonWeave, where local transcription continues. Sharing somebody else's message still requires appropriate consent and lawful use. ## Pricing The current launch plan is a one-time App Store purchase. Local currencies, taxes and Apple storefront tiers can change the displayed amount. The current paid version does not require a monthly or annual transcription subscription. The generated pricing reference at https://sonweave.com/pricing.md is the source for the current configured amount. The website includes a centrally configured arithmetic comparison between monthly recurring pricing and the one-time purchase. See https://sonweave.com/pricing.md for the current values. This is context for recurring pricing; it is not a claim that every competitor charges exactly that amount. The one-time purchase includes the current paid application and planned 1.x updates. It does not promise every possible future major version or platform. SonWeave does not sell its own remote transcription minutes. Practical limits still exist: long files require device storage, processing time, battery and memory, and local models occupy storage. ## Comparison with cloud transcription services Cloud-first services can offer server-scale processing, collaboration dashboards and features that do not fit every phone. They also require audio or text to reach remote infrastructure and commonly use recurring plans. SonWeave prioritizes a private local workflow, ownership of exported files, no mandatory SonWeave account and one-time launch pricing. The correct choice depends on the user's needs. SonWeave is relevant when local processing, speaker-aware transcripts, transcript chat, broad engine-aware language selection and flexible export matter more than a shared cloud workspace. ## Comparison with Whisper Notes Whisper Notes is a separate product that helped demonstrate demand for private offline transcription and one-time pricing. SonWeave shares those broad principles but emphasizes a workflow after raw transcription: offline speaker diarization, transcript-grounded chat, local summaries and study tools, shared language compatibility between the app and share extension, and multiple compatible engine families. This comparison does not claim that SonWeave is universally better. Users should compare current App Store listings, device support, tested accuracy, exports, privacy policies and prices for their own recordings. ## Important limitations - Transcripts can contain errors. - Speaker diarization can merge or split voices incorrectly. - AI summaries and answers can be inaccurate. - Engine and language availability varies by device and system version. - Some models and Apple language assets require an initial download. - Local processing consumes storage, memory, battery and time. - Optional iCloud and external sharing require a network connection. - Background execution can be constrained by iOS or iPadOS. - SonWeave does not replace consent or recording law. ## Primary English pages - Product overview: https://sonweave.com/ - Best offline transcription app: https://sonweave.com/best-offline-transcription-app/ - Offline transcription: https://sonweave.com/offline-transcription/ - Offline voice to text: https://sonweave.com/voice-to-text-offline/ - Meeting transcription: https://sonweave.com/meeting-transcription/ - Interview transcription: https://sonweave.com/interview-transcription/ - WhatsApp voice-message transcription: https://sonweave.com/whatsapp-voice-message-transcription/ - Audio and video transcription: https://sonweave.com/transcribe-audio-video/ - Speaker diarization: https://sonweave.com/speaker-diarization/ - Transcript chat: https://sonweave.com/transcript-chat/ - Apple Speech vs Whisper vs Parakeet: https://sonweave.com/apple-speech-vs-whisper-vs-parakeet/ - Transcription languages: https://sonweave.com/transcription-languages/ - One-time-purchase transcription app: https://sonweave.com/one-time-purchase-transcription-app/ - Privacy-first transcription: https://sonweave.com/privacy-first-transcription/ - Whisper Notes alternative: https://sonweave.com/whisper-notes-alternative/ ## Localized discovery pages The six core discovery topics — offline transcription, speaker diarization, transcript chat, best offline transcription app, transcription languages and one-time pricing — are published under these locale prefixes: - German: /de/ - Spanish: /es/ - French: /fr/ - Italian: /it/ - Brazilian Portuguese: /pt-br/ - Dutch: /nl/ - Polish: /pl/ - Turkish: /tr/ - Arabic: /ar/ - Hindi: /hi/ - Indonesian: /id/ - Japanese: /ja/ - Korean: /ko/ - Simplified Chinese: /zh-hans/ - Traditional Chinese: /zh-hant/ Each localized page uses its own visible translation, title, description, canonical URL, structured FAQ data and reciprocal hreflang references. ## Support and legal sources - Support: https://sonweave.com/support.html - Privacy Policy: https://sonweave.com/privacy.html - Terms of Use: https://sonweave.com/terms.html - Legal Notice: https://sonweave.com/imprint.html - App Store: https://apps.apple.com/app/id6768983936 ## Developer SonWeave AI Notes is developed by Silestis Labs UG (haftungsbeschränkt), Munich, Germany.
