Everything You Need for Smarter Browsing
Free Extension
VeloFill is free to install and use. Bring your own OpenAI-compatible LLM; you control any model costs.
Bring your own AI
VeloFill connects to any OpenAI-compatible service—commercial, Azure-hosted, or local. Add multiple connections, keep work and personal keys separate, and choose a default in seconds.
Your private knowledge base
All your information is stored securely in a private knowledge base on your own computer, not in the cloud.
Per-KB Routing
Assign a specific connection to each knowledge base or let it inherit the default. Every form is powered by the right API key automatically.
Intelligent Field Recognition
VeloFill analyzes a form's structure, labels, and surrounding text to understand each field in context. This helps it distinguish between 'First Name' and 'Last Name' and map answers for longer fields like 'Cover Letter'.
Customizable Instructions
Tailor Prompt Instructions per knowledge base to match tone, formatting, or compliance needs before the model fills anything in.
Fast Autofill
Fill many forms quickly with one click or a keyboard shortcut. Speed depends on the page and model you choose.
Secure by Design
Your knowledge base stays on your device. Enable vault encryption to lock knowledge bases and API keys with a master password, and send requests over HTTPS only to the endpoints you configure.
