Show HN: I built a voice AI that responds like a real woman Most men rehearse hard conversations in their head. Asking someone out, navigating tension, recovering when things get awkward. The rehearsal never works because you're just talking to yourself. I built vibeCoach : a voice AI where you actually practice these conversations out loud, and the AI responds like a real woman would. She starts guarded. One-word answers, a little skeptical. If you escalate too fast or try something cheesy, she gets MORE guarded. If you're genuine and read the moment right, she opens up. Just like real life. Under the hood it's a multi-agent system : multiple AI agents per conversation that hand off to each other as her emotional state shifts. The transitions are seamless. You just hear her tone change. Voice AI roleplay is a proven B2B category : sales teams use it for call training. I took the same approach and pointed it at the conversation most men actually struggle with. There's a hard conversation scenario too : she's angry about something you did, she's not hearing logic, and you have to navigate her emotions before you can resolve anything. That one's humbling. Live at tryvibecoach.com. Built solo. Happy to answer questions. March 26, 2026 at 12:38AM

Show HN: Τ³-Bench is out – can agents handle complex docs and live calls? https://ift.tt/QPtIGcA

Show HN: Τ³-Bench is out – can agents handle complex docs and live calls? τ-Bench is an open benchmark for evaluating AI agents on grounded, multi-turn customer service tasks with verifiable outcomes. It's been great to see the community adopt it since launch — this is now the third iteration. With τ³-Bench, we're extending it to two new settings: knowledge-intensive retrieval and full-duplex voice. τ-Knowledge: agents must navigate ~700 interconnected policy documents to complete multi-step tasks. Best frontier model (GPT-5.2, high reasoning) hits ~25%. The surprising part: even when you hand the model the exact documents it needs, performance only reaches ~40%. We found that the bottleneck isn't retrieval — it's reasoning over complex, interlinked policies and executing the right actions in the right order. τ-Voice: same grounded tasks, but over live full-duplex voice with realistic audio — accents, background noise, interruptions, compressed phone lines. Voice agents score 31–51% in clean audio conditions and 26–38% in realistic ones. A consistent failure pattern across providers (OpenAI, Gemini, xAI): agent mishears a name or email during authentication, and everything downstream fails. We also incorporated 75+ task fixes to the original airline, retail, and telecom domains — many based on community audits and PRs (including contributions from Amazon and Anthropic). We believe a benchmark is only as good as its maintenance, and we're grateful for the community's help improving it. Code and leaderboard are open — we'd welcome community submissions and feedback.

Show HN: Gridland: make terminal apps that also run in the browser https://ift.tt/5OaA6dy

Show HN: Gridland: make terminal apps that also run in the browser Hi everyone, Gridland is a runtime + ShadCN UI registry that makes it possible to build terminal apps that run in the browser as well as the native terminal. This is useful for demoing TUIs so that users know what they're getting before they are invested enough to install them. And, tbh, it's also just super fun! Gridland is the successor to Ink Web (ink-web.dev) which is the same concept, but using Ink + xterm.js. After building Ink Web, we continued experimenting and found that using OpenTUI and a canvas renderer performed better with less flickering and nearly instant load times. We're excited to continue iterating on this. I expect a lot of criticism from the "why does this need to exist" angle, and tbh, it probably doesn't - it's really mostly just for fun, but we still think the demo use case mentioned previously has potential. - Chris + Jess https://ift.tt/uYbI8NU March 24, 2026 at 10:27PM

Working with Communities to Make Schools Safer: This Year’s Walk Audits

Working with Communities to Make Schools Safer: This Year’s Walk Audits
By Nehama Rogozen

School staff, parents, community members and SFMTA staff gather at Alvarado Elementary School to conduct a Walk Audit. Getting kids to school safely is a top priority for our teams at the SFMTA. One way we create safer conditions is through our School Walk Audit Program. Each year, we select 10 schools for this program. So, what is a school walk audit? It's just like it sounds. SFMTA staff join school and community representatives to walk the area and look for things that make it harder to walk to school safely. That could be: Faded striping on the roads Tricky crossings Blind spots People...

Show HN: Minimalist library to generate SVG views of scientific data https://ift.tt/O63JtPh

Show HN: Minimalist library to generate SVG views of scientific data Just wanted to share with HN a simple/minimal open source Python library that generates SVG files visualizing two dimensional data and distributions, in case others find it useful or interesting. I wrote it as a fun project, mostly because I found that the standard libraries in Python generated unnecessarily large SVG files. One nice property is that I can configure the visuals through CSS, which allows me to support dark/light mode browser settings. The graphs are specified as JSON files (the repository includes a few examples). It supports scatterplots, line plots, histograms, and box plots, and I collected examples here: https://ift.tt/igbXkvA... I did this mostly for the graphs in an article in my blog ( https://alejo.ch/3jj ). Would love to hear opinions. :-) https://ift.tt/AKFIMVv March 23, 2026 at 11:24PM
