The Problem:

I've always been frustrated by how much time I waste retyping the same information across different websites like job applications, dating profiles, rental forms, surveys, etc. Existing password managers only handle credentials, and browser autofill is limited to basic contact info. I wanted something smarter.

What We Built:

Superfill.ai creates an intelligent memory layer that stores your information once (as question-answer pairs) and uses AI to contextually match and auto-fill form fields across ANY website.

Key Features:

* AI-Powered Matching: Uses LLMs (OpenAI, Anthropic, Groq, DeepSeek, Google, Ollama) to understand form context and match fields to stored memories with confidence scoring * BYOK Model: Bring your own API keys so no vendor lock-in, you control your AI costs * Privacy-First: AES-256 encryption for API keys, local-first storage (Phase 1), zero telemetry * Smart Memory Management: AI categorization, tagging, rephrasing, search/filter/sort * Import/Export: CSV support for bulk operations and backups * Cross-Browser: Works on Chrome, Edge, and Firefox (Safari in progress)

Current Status:

Phase 1 is complete! Core memory management and AI auto-fill work for input & textarea fields. We're now working on Phase 2: select/radio/checkbox fields, Safari support, cloud sync (premium), semantic search, and more.

Open Source Commitment:

Core features will ALWAYS remain free and open source (MIT license). We're exploring premium features like cloud sync and advanced templates, but the fundamental autofill functionality stays free forever.

Why Share Here:

We'd love technical feedback on our architecture (especially the AI matching algorithm) Looking for contributors interested in browser extensions, AI integration, or privacy-first design. Also, we want to understand if this solves a real problem for the HN community.
