Frequently Asked Questions
What do the tone sliders control?
- Formality (Casual ↔ Formal): Controls language style from conversational/informal to professional/academic. Move left for friendly tone, right for business/academic tone.
- Emotion (Neutral ↔ Emotional): Controls emotional expression from objective/detached to passionate/emphatic. Move left for facts-only, right for expressive language.
- Directness (Indirect ↔ Direct): Controls communication style from polite/subtle to clear/assertive. Move left for diplomatic phrasing, right for straightforward statements.
How does "Analyze Tone" differ from "Adjust Tone"?
Analyze Tone: Evaluates your current text and provides a tone profile showing where your writing falls on each scale. It doesn't change your text - just helps you understand its current tone.
Adjust Tone: Rewrites your text to match the slider positions you set. This actively transforms your writing to achieve the desired tone while preserving your core message.
Use "Analyze" first to understand your starting point, then "Adjust" to make changes.
What is tone consistency checking for long documents?
For longer documents, the tool analyzes tone consistency throughout your text. It identifies sections where tone shifts unexpectedly (e.g., starting formal and becoming casual midway). The consistency checker helps ensure your entire document maintains a unified voice, which is especially important for professional and academic writing.
Does this tool store my text?
No. Your privacy is our priority. We never store, log, or share your text. Processing happens via secure AI APIs, and the text is immediately discarded after analysis. Your history is saved locally in your browser only (using IndexedDB) and never sent to our servers.
What's the character limit?
You can analyze and adjust up to 5,000 characters at once. For longer documents, we recommend breaking them into sections and processing each separately. This also gives you more control over tone adjustments in different parts of your document.
Can I use this for professional or academic writing?
Yes! The tone checker is perfect for ensuring your writing matches the expected tone for your context. Use it to:
- Make emails more professional or friendly as needed
- Ensure academic papers maintain formal, objective tone
- Adjust cover letters to be confident but not overly assertive
- Balance professionalism with approachability in business communication
Always review the adjusted text to ensure it still accurately conveys your intended message.
