The YC-backed startup offers a full-featured voice-powered keyboard with deep personalization and seamless editing for productivity on the go.
Voice Tech Meets Everyday Typing
Willow, a Mac voice tool turned iOS keyboard app, is redefining how users interact with their devices. By enabling voice typing across all iOS apps, the startup is making it easier to dictate, format, and edit spoken input on the fly—no app-switching required.
The app’s standout feature is its full QWERTY keyboard, which sets it apart from competitors like Wispr Flow, which only offers a numeric layout. This allows users to combine typing with dictation, making quick fixes and manual inputs easy.
Smarter Voice, Smarter Context
Willow uses AI transcription enhanced by a text-to-text pipeline based on Meta’s Llama models. This enables it to:
- Understand context across categories like work, messaging, and email
- Offer personalized formatting and vocabulary
- Support over 100 languages
Users can define custom terms and tones, creating consistent writing styles across different applications—a powerful edge for professionals and multilingual users alike.
From Healthcare to Voice Productivity
The founders, Allan Guo and Lawrence Liu, pivoted to voice tools after experimenting with various ideas in Y Combinator. Originally building healthcare software, their breakthrough came from observing how doctors use voice AI scribes for documentation.
This inspired them to target knowledge workers, where voice-powered communication extends beyond meetings into everyday productivity tools. Instead of creating another AI notetaker, Willow set out to improve general-purpose dictation, a space they saw as underdeveloped.
Growth, Funding & Vision
Since its spring 2025 YC re-launch, Willow has grown 50% month-over-month, attracting both individual users and enterprise clients like:
- Uber
- Heidi Health
- Zego
The company has raised $4.5 million from backers including:
- Box Group
- Burst Capital
- Y Combinator
- Angels like Dharmesh Shah (HubSpot), Tomer London (Gusto), and Alexis Ohanian (Reddit)
Investors believe Willow is not just a dictation tool but the start of voice-led user interfaces for the future.
A More Human Workflow
What makes Willow truly compelling is its reduction in manual editing, a major friction point with traditional dictation systems. Users can also trigger commands like drafting emails using desktop voice prompts such as “Hey Willow”, creating a hands-free writing assistant that mirrors their own tone.
Instacart co-founder Max Mullen, an angel investor, emphasized the value:
“When I write through Willow, I need to make fewer edits than with a computer’s built-in dictation system.”
The Road Ahead
Looking forward, Willow plans to:
- Expand to Windows and Android
- Refine its personalization to minimize post-dictation edits
- Deepen its integration into daily workflows through AI-enhanced voice control
As the competition heats up with players like Wispr Flow, Superwhisper, and Betterdictation, Willow’s hybrid interface and developer-first ethos may offer it an edge in becoming the default voice companion for modern computing.
