NovaVoice▲578Hey HN, Today I’d like to show what I’ve recently built with my 2 friends. We’ve called it Nova.

How we decided to work on it: We’ve recently read YC Request for startups Summer25 and were inspired by the idea of AI Voice Assistant for Mail by YC partner Tyler Bosmeny. What we’ve got: We’ve gone a bit further than Assistant for mail only and connected Gmail, Todoist, Google Calendar, and…

PromptForge▲474PromptForge: Open-source AI prompt engineering workbench with systematic evaluation I built PromptForge after getting frustrated with the manual trial-and-error approach to prompt engineering.

Key technical features: - AI-assisted prompt generation (stop starting from scratch) - Systematic evaluation engine that auto-generates test suites - Multi-model support (Claude, GPT-4, Azure OpenAI) - Go backend with SQLite for performance and simplicity - One-line Docker…

Henry, Matt and James here – we’re building an open source toolkit that makes it easy to integrate an LLM-powered copilot that talks to your API into software products.

It’s also open source, so you don’t have to send user data to another 3rd party. We support Llama 2, but we haven’t fine-tuned Llama 2 yet (coming soon) so highest accuracy is seen with GPT-4 or fine-tuned GPT-3.5 (much faster). We started working together 2…
