Why ScreenApp Beats ChatGPT for Threema Transcription
ChatGPT cannot process audio files directly because it only accepts text and image input. If you try to transcribe a Threema voice message through ChatGPT, you would first need to run the file through a separate speech-to-text API, then paste the result back in for cleanup. That means two tools, extra steps, and no speaker labels.
ScreenApp handles the full Threema transcription workflow in one place. Upload your voice message or audio recording, and you get a complete transcript with speaker identification, timestamps, and AI-generated summaries. No API keys, no file conversion, no workarounds.
Threema itself does not include any built-in transcription feature. The app is built around end-to-end encryption and minimal server storage, which means voice messages stay as audio files with no native text conversion. If you want a written version of your Threema conversations, you need an external tool.
ScreenApp fills that gap. It accepts OGG, MP3, MP4, WAV, and other common formats without requiring conversion. Upload the file, and the platform returns accurate text in seconds across 120+ languages.

How Threema Transcription Works
Transcribing your Threema voice messages takes three steps:
-
Export and upload your file - Open your Threema chat, save the voice message or audio file to your device, then upload it to ScreenApp. The tool accepts OGG (Threema’s default format), MP3, MP4, WAV, and most standard audio formats. You can also paste a URL if the file is hosted online.
-
Automatic processing with speaker detection - ScreenApp processes the audio and generates a full text transcript within seconds. When the recording includes multiple speakers, the platform identifies and labels each one so you can follow who said what.
-
Export, search, or transform - Download your transcript as a text file, or use the built-in AI tools to translate it into another language, search for specific phrases, generate a summary, or reformat the content for meeting notes or documentation.
The entire process runs in your browser. Unlike other transcription services that require desktop software or mobile apps, this tool works on any device with an internet connection.

Key differences:
-
vs Threema (Built-in): Threema has no native transcription at all. Its privacy-first architecture prioritizes encryption over convenience features, so voice messages remain as audio files with no text conversion option.
-
vs Otter.ai: Otter.ai charges $16.99/month for its Pro plan and caps free users at 300 minutes with a 30-minute-per-conversation limit. It is also built primarily for English-language meetings rather than messaging app voice notes. ScreenApp requires no account and handles Threema’s OGG format directly.
-
vs Rev: Rev offers 45 free AI transcription minutes per month, with paid plans starting at $8.33/month plus $0.25 per audio minute on top. Human transcription costs $1.99 per minute. ScreenApp provides a simpler pricing structure without per-minute charges.
-
vs Notta.ai: Notta’s free plan gives only 120 total minutes with a 3-minute-per-recording limit, making it impractical for anything beyond a quick test. The Pro plan costs $8.17/month billed annually. ScreenApp has no per-recording time cap on its free tier.
-
vs Sonix: Sonix charges $10 per audio hour on its Standard plan, with no monthly subscription required. Its Premium plan adds a $22/month base fee plus $5 per hour of audio. ScreenApp is a better fit for users who want straightforward pricing without per-hour charges.
Use Cases for Threema Transcription
Privacy-conscious professionals: Threema is popular among users who prioritize encrypted communication. Transcribing voice messages creates searchable records without compromising the reason you chose the app in the first place. ScreenApp processes files in your browser and does not store recordings permanently.
Remote teams: Teams that rely on Threema for async voice updates can convert those messages into written records. This keeps everyone aligned without forcing members to replay long audio files.
Journalists and researchers: Interview subjects who prefer the app for its anonymity features often send voice recordings. Transcribing those produces searchable, quotable text with accurate speaker attribution.
Students and study groups: Group discussions shared through voice notes become study materials once transcribed. You can search for specific topics, copy relevant sections, and organize notes by speaker.
Multilingual teams: With support for 120+ languages, ScreenApp handles voice messages in any language and can translate the transcript afterward. Teams communicating across language barriers save time by working from written translations instead of re-listening to audio.
