VoicePrompt

Let your thoughts flow. Turn them into clear text. Voice Prompt helps you capture spoken ideas and shape them into useful drafts on iPhone and iPad. Start with an AI prompt, a work brief, or a quick note. Say what you mean, then refine it as you go. 【FROM SPOKEN IDEAS TO A CLEAR DRAFT】 Record your thoughts and review the transcription. Use your configured AI service to remove filler words, improve punctuation, and clarify the wording. Keep editing, or return to your local history to pick up an earlier idea. 【EDIT WITH YOUR VOICE】 Continue dictating to add content, or describe the change you want, such as “Make this paragraph more concise.” Use rewriting, structured formatting, and Markdown preview to turn a rough draft into something ready to use. 【KEEP YOUR SKILLS CLOSE】 Manage and import reusable Skill instructions, then insert them into your drafts or prompts. Save recurring requirements so you can use them again without typing them out each time. 【CONTINUE FROM YOUR KEYBOARD】 Enable the keyboard extension to access quick phrases, Skills, and text tools in apps and fields that support third-party keyboards. Voice recording takes place in the main app; the recognized text can return to the keyboard for insertion. 【CHOOSE YOUR SETUP】 Select your speech recognition engine and AI service. Local speech models can transcribe offline once the required models are available. Remote recognition and AI text processing require a network connection and service configuration. The interface supports Simplified Chinese, Traditional Chinese, and English. 【PRIVACY AND SECURITY】 Your draft history and voiceprint profiles are stored on your device. You can manage or delete them in the app. When you use a local speech model, recognition runs on your device. You choose and configure your speech recognition and AI services. System speech recognition may use Apple's online services. Remote recognition and AI text tools send the relevant audio or text to the selected provider, subject to that provider's privacy policy. Offline transcription does not make remote AI features available offline. Microphone access and keyboard Full Access are managed by the system. You can change these permissions in your device settings. 【BEFORE YOU START】 • Basic transcription and local history are available for free. Voice editing, advanced text tools, Skills, Markdown preview, and some keyboard enhancements require the Pro Unlock in-app purchase. • AI text processing and remote recognition require a configured service and may require your own API key. Any third-party service charges are separate from the in-app purchase. • Enable the keyboard extension in system settings. Some features may require Full Access. Availability depends on the system and the app or input field you are using.

Verdict
The clearest difference is device support: VoicePrompt at 3 against Snapdf's 1. VoicePrompt also leads on iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.
