Voice Typing in Any App: The Complete Guide
Most people don't realize that voice typing doesn't have to be limited to Google Docs or note-taking apps. With the right tool, you can use AI-powered voice typing in literally every app on your phone — WhatsApp, Gmail, Slack, Instagram, ChatGPT, Notion, and hundreds more.
This guide shows you how to set up and use voice typing across all your most-used apps, using Zavi AI as a system-wide keyboard that works everywhere.
Step 1: Install Zavi AI as Your Keyboard
The key to using voice typing in every app is installing a voice-first keyboard that replaces your default keyboard system-wide.
- Download Zavi AI from the Google Play Store (free)
- Open Settings → System → Language & Input → On-screen keyboard
- Enable "Zavi AI Keyboard"
- Set Zavi as your default keyboard
Now, whenever you tap any text field in any app, Zavi's keyboard appears with a microphone button ready for voice input.
Voice Typing in WhatsApp
Use case: Sending quick messages, replying to group chats, composing long messages
- Open any WhatsApp chat
- Tap the message input field (Zavi keyboard appears)
- Tap the 🎤 microphone icon on the Zavi keyboard
- Speak naturally — "Hey Sarah, I'll be about 15 minutes late to the meeting, the traffic is pretty bad today, sorry about that"
- Zavi outputs: "Hey Sarah, I'll be about 15 minutes late to the meeting. Traffic is pretty bad today — sorry about that!"
- Hit send. Done in 5 seconds instead of 30 seconds of typing.
Voice Typing in Gmail
Use case: Composing professional emails, replying to threads, writing detailed responses
This is where Zavi truly shines. Emails require professional tone, proper grammar, and clear structure — all things the AI handles automatically. You can dictate an entire professional email in 30 seconds that would take 5 minutes to type and proofread.
Example: Say: "Hi team, I wanted to share a quick update on the Q1 numbers. Revenue is up 23% compared to last quarter, which is above our target. The main driver was the enterprise segment, which grew by 40%. I've attached the detailed report for your review. Let me know if you have any questions."
Zavi outputs that as perfectly formatted, professional text — comma placement, capitalization, and all.
Voice Typing in Slack
Use case: Quick status updates, detailed thread replies, channel announcements
Slack messages can range from casual ("sounds good!") to professional (project updates). Zavi adapts its cleanup level based on context and message length.
Voice Typing in Notion, Google Docs & Notes
Use case: Meeting notes, brainstorming, document drafting, journaling
For longer-form content, voice typing is transformative. Dictating a 500-word document takes about 3 minutes versus 12 minutes of typing. Zavi's grammar correction means the first draft is nearly final quality.
Voice Typing in ChatGPT, Gemini & Claude
Use case: Speaking your prompts to AI assistants naturally
Instead of carefully typing prompts, simply speak them. Say: "Write me a marketing email for our new product launch targeting enterprise customers, emphasize the ROI and include a call to meeting." Zavi cleans it up into a clear, well-structured prompt.
Pro Tips for Voice Typing in Any App
- Speak naturally: Don't try to "write out loud." Talk like you would to a colleague. Zavi handles the formalization.
- Don't worry about fillers: Say "um" and "uh" as much as you naturally do — the AI removes them all.
- For multilingual messages: You can speak in your native language and Zavi will output in your target language. Perfect for replying in English to a colleague when you think in Hindi, Spanish, or French.
- Long messages are better: The AI has more context to work with in longer dictations, producing even better output.
