Understand what works and what doesn't… ## Limitations & Constraints VoxWrite is a powerful voice-to-text tool, but like any software, it has certain limitations. Understanding these constraints will help you use VoxWrite more effectively. --- ## Browser & Platform Limitations ### Chrome Extension Only **Current limitation:** - ✅ Works on: Chrome. Probably it works in all Chromium-based browsers (Edge, Brave, Opera), but it's still in a testing mode. - ❌ Does NOT work on: Firefox, Safari, mobile browsers **Why:** VoxWrite is built as a Chrome Extension using Chrome APIs. **Workaround:** Use Chrome or Chromium-based browser for VoxWrite functionality. --- ### Desktop Only (No Mobile Support) **Current limitation:** - ✅ Works on: Windows, Mac, Linux desktop - ❌ Does NOT work on: iOS, Android, tablets **Why:** Chrome Extensions don't run on mobile browsers. **Future:** Mobile app may be considered based on user demand. --- ### Internet Connection Required **Current limitation:** - AI transformation requires active internet connection - Audio transcription requires connection to OpenAI/Anthropic servers **Why:** AI models run on cloud servers, not locally. **Workaround:** Basic transcription might work offline in future updates, but AI transformation always requires internet. --- ## Website Compatibility Issues ### Some Websites Block Microphone Access **Affected sites:** - Banking websites (security restrictions) - Some enterprise applications - Websites with strict Content Security Policy (CSP) - Sites that override browser microphone permissions **Why:** Website security policies prevent extensions from accessing microphone. **Workaround:** - Use VoxWrite in side panel to record, then copy/paste text - Check if website allows microphone in browser settings --- ### Text Insertion May Not Work Everywhere **Limitation:** - VoxWrite can't insert text into some protected fields: - Password fields - Credit card input fields - Some rich text editors (WYSIWYG) - Canvas-based text editors - Shadow DOM elements **Why:** Browser security prevents extensions from modifying certain input types. **Workaround:** Copy text from VoxWrite and manually paste it. --- ## Recording & Audio Limitations ### Background Noise Affects Accuracy **Current limitation:** - High background noise reduces transcription accuracy - Multiple speakers may confuse the AI - Music or TV in background causes errors **Best practices:** - Record in quiet environment - Use quality microphone - Speak clearly and at moderate pace --- ## AI & Language Processing Limitations ### Language Support Varies by Model **Transcription (Audio Model):** - GPT-4o Mini Transcribe: 50+ languages - Whisper-1: Excellent multilingual support - Quality varies by language (English best supported) **Post-processing (AI Transformation):** - Works best with: English, Spanish, French, German, Chinese, Japanese - May struggle with: Less common languages, dialects, slang **Limitation:** Some languages may have lower accuracy or slower processing. --- ### AI Transformation Not Perfect **Current limitations:** - AI may misinterpret context occasionally - Complex instructions may not always be followed exactly - Creative or nuanced writing may lose personal touch - Technical jargon may be misunderstood **Why:** AI models have inherent limitations in understanding context. **Best practice:** Review and edit AI-transformed text before sending important messages. --- ### Custom Prompts Have Limits **Constraints:** - Very complex prompts may confuse the AI - Contradictory instructions cause unpredictable results - Extremely long prompts may be truncated - Some formatting requests may not work perfectly **Recommendation:** Keep prompts clear, specific, and under 500 characters. --- ## Performance Limitations ### Processing Speed Varies **Factors affecting speed:** - AI model selected (faster models = lower quality) - Recording length (longer = slower processing) - Internet connection speed - API provider server load - Complexity of custom prompt **Typical processing times:** - 30 seconds of audio: 2-5 seconds to process - 5 minutes of audio: 10-30 seconds to process --- ## Feature Limitations ### No Real-Time Transcription **Current limitation:** - You must stop recording before seeing transcribed text - No live preview of transcription while speaking **Why:** API calls happen after recording completes. **Future:** Real-time transcription may be added in future updates. --- ### No Collaboration Features **Current limitation:** - No team sharing of recordings - No shared custom rules or templates - No multi-user accounts **Why:** VoxWrite is designed as individual productivity tool. **Future:** Team features may be considered based on demand. --- ### No Offline Mode **Current limitation:** - Cannot transcribe audio without internet - Cannot apply AI transformations offline - Extension requires online activation **Why:** AI models run on cloud servers. **Partial workaround:** Record audio offline, process when connection returns (not yet implemented). --- ### No Video or Screen Recording **Current limitation:** - Audio only - no video recording - No screen capture integration - No meeting recording (use dedicated tools) **Why:** VoxWrite focuses on voice-to-text, not multimedia recording. --- ## Conclusion VoxWrite is actively developed and many limitations will be addressed in future updates. Understanding current constraints helps you: - Set realistic expectations - Find workarounds when needed - Use VoxWrite more effectively - Provide valuable feedback for improvements **Most limitations don't affect daily use for 90% of users.** The core functionality—voice to text with AI transformation—works reliably across most websites and use cases. --- If you have any questions, feature request, whatever, please use our [contact form.](https://voxwrite.app/contact) --- [{"<<"} How to switch between pricing plans](https://voxwrite.app/docs/switch-plan) ## Related - HTML version of this page: https://voxwrite.app/docs/constraints - Site map for agents: https://voxwrite.app/llms.txt
