Show HN: Sourcebot – Self-hosted Perplexity for your codebase 17 by bshzzle | 1 comments on Hacker News. Hi HN, We’re Brendan and Michael, the creators of Sourcebot ( https://ift.tt/VYzAJZP ), a self-hosted code understanding tool for large codebases. We originally launched on HN 9 months ago with code search ( https://ift.tt/xMdNSpO ), and we’re excited to share our newest feature: Ask Sourcebot. Ask Sourcebot is an agentic search tool that lets you ask complex questions about your entire codebase in natural language, and returns a structured response with inline citations back to your code. Some types of questions you might ask: - “How does authentication work in this codebase? What library is being used? What providers can a user log in with?” ( https://ift.tt/LQb0UlD ) - “When should I use channels vs. mutexes in go? Find real usages of both and include them in your answer” ( https://ift.tt/rp7Y34N ) - “How are shards laid out in memory in the Zoekt code search engine?” ( ht...

Show HN: Local Email Client for AI Horseless Carriages 6 by shahahmed | 1 comments on Hacker News. The AI Horseless Carriages article spurred a lot of conversation about how we should just be giving users the system prompt box [0], and we were pretty surprised that a bunch of email clients didn’t pop up following this pattern [1]. So we went ahead and created a local [2] email client that you can run that processes your inbox with your own handwritten rules. It lets you label and archive based on natural language rules. You can draft responses with your own drafting prompt, and there’s a “research sender” option that uses web search to get public info on a sender. You can customize any of the prompts to fit your needs. We’d love to hear what you think and PRs/issues are welcome!

Show HN: RULER – Easily apply RL to any agent 5 by kcorbitt | 0 comments on Hacker News. Hey HN, Kyle here, one of the co-founders of OpenPipe. Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it's so hard to implement. One of the biggest challenges when adapting RL to a new task is the need for a task-specific "reward function" (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and/or significant domain expertise to generate. RULER is a drop-in reward function that works across different tasks without any of that complexity. It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores with...

Launch HN: Leaping (YC W25) – Self-Improving Voice AI 10 by akyshnik | 2 comments on Hacker News. Hey HN, I'm Arkadiy from Leaping AI ( https://leapingai.com ). Leaping lets you build voice AI agents in a multi-stage, graph-like format that makes testing and improvement much easier. By evaluating each stage of a call, we can trace errors and regressions to a particular stage. Then we autonomously vary the prompt for that stage and A/B test it, allowing agents to self-improve over time. You can talk to one of our bots directly at https://leapingai.com , and there’s a demo video at https://www.youtube.com/watch?v=xSajXYJmxW4 . Large companies are understandably reluctant to have AI start picking up their phone calls—the technology kind of works, but often not very well. If they do take the plunge, they often end up spending months tuning the prompts for just one use-case, and sometimes never even end up releasing the voice bot. The problem is two-sided: it's non-trivial to spe...
