Why Ottex works for data scientists
Concrete benefits with real-world impact
Custom Dictionary
Add names, technical terms, and jargon. Ottex transcribes them accurately every time.
Precision Typing
Say 'new paragraph', 'open quote', 'em dash', 'ellipsis'. Full formatting control by voice.
Voice Corrections
Say 'scratch that' to delete mistakes, 'actually' to rephrase. Fix errors without stopping your flow or touching the keyboard.
Better Context, Better Results
Speaking naturally gives AI agents more context than typing. Describe your intent, explain edge cases, mention file names—your voice carries nuance that typing shortcuts.
Works with AI Chatbots
Dictate prompts to ChatGPT, Claude, Perplexity—anywhere you type. Better prompts, better answers.
Inline AI Commands
Transform text as you speak: 'Ottex start fix grammar Ottex end'. Edit, improve, translate—all by voice.
Technical Term Accuracy
Cloud AI models excel at technical jargon, code terminology, and specialized vocabulary.
Global Shortcuts
Start recording with Option+D, use Push-to-Talk, or cancel with Esc. All shortcuts are fully configurable.
Works in Any App
System-wide on macOS—Ottex works wherever you can type. No app-specific integrations needed.
Filler Word Removal
Automatically removes filler words like 'um', 'uh', 'like', 'so' from your transcription. Get clean, professional text without verbal hesitations.
App-Specific Modes
Ottex detects which app you're in and adapts. Coding mode in Cursor, casual tone in Slack, professional in Gmail—automatic context switching.
Context Awareness
Optionally let AI see your screen for smarter responses. Reply to emails with full context, answer messages knowing the conversation history.
Smart Snippets
Define custom text replacements and shortcuts. Say 'work signature' to expand your full email signature, or 'my address' for your contact info.
What you can do
Write Research Notes
Dictate research notes, literature summaries, or analysis. Capture your thinking process without losing momentum to typing.

Write Documentation
Dictate technical documentation, READMEs, or API docs. Speaking lets you explain context, edge cases, and examples naturally—better docs with less effort.
Works with
VS Code
Example dictation
so the authentication flow works like this colon new paragraph first the client sends credentials to the auth service second the auth service validates against the database and returns a JWT token third the client stores the token and includes it in subsequent requests new paragraph note colon we're using r s 2 5 6 for token signing
Read this example aloud, or say something of your own.
Ottex outputs
The authentication flow works like this:
1. The client sends credentials to the auth service
2. The auth service validates against the database and returns a JWT token
3. The client stores the token and includes it in subsequent requests
Note: We're using RS256 for token signing

Capture Ideas Quickly
Speak ideas the moment they hit you. Use Ottex anywhere to capture thoughts, then refine them later.
Works with
Text Editor
Example dictation
oh okay so what if we flip the onboarding completely um instead of asking users to set up their workspace first we let them record something immediately like within 10 seconds of signing up they're already talking and seeing the magic actually no not 10 seconds make it the very first screen and then we save that as their first note so they have an aha moment before they even configure anything

Frequently asked questions
Does it handle technical ML terminology?
Yes. Cloud models like Gemini 3 Flash are trained on ML papers, documentation, and code. They handle 'XGBoost,' 'SHAP values,' 'attention mechanism,' 'hyperparameter tuning,' and thousands of other technical terms accurately. For project-specific terms (custom model names, internal tools), add them to your custom dictionary.
Can I dictate into Jupyter notebooks?
Yes. Ottex works anywhere you can type on macOS, including Jupyter in VS Code, JupyterLab in the browser, and Google Colab. Dictate markdown cells for documentation, code comments, and experiment observations.
How does it help with prompting ChatGPT or Claude?
AI assistants produce better answers when you provide rich context. But typing a 200-word prompt explaining your dataset, model architecture, and specific question takes 5 minutes. Speaking it takes 45 seconds. More context = better answers, and voice removes the friction.
Will it slow down my machine during model training?
No. Ottex uses less than 2% CPU because it's native Swift, not Electron. Cloud transcription happens via API. When you're running GPU-intensive training, Ottex won't compete for resources.
Can I use it for explaining models to non-technical stakeholders?
Absolutely. Work modes let you configure different formatting per app. When you're writing in Notion for stakeholders, your explanations can be clear and jargon-free. When you're documenting in Jupyter for other data scientists, you can use full technical precision.
How much does it cost?
Free forever with local models (Whisper runs on your Mac). Or bring your own API key for cloud models—most data scientists spend ~$1-3/mo. If you want zero setup, the $9/mo premium tier includes Gemini 3 Flash with 99.1% accuracy.
