Respan Gateway

Respan AI Gateway connects your app to 1,000+ AI models through one endpoint. But routing is the easy part. Respan keeps production AI reliable and under control with fallbacks, retries, caching, spend limits, alerts, and full traces for every call. Gateway, observability, evals, prompt management, monitors, and cost controls all run on one platform, so you do not need to stitch together five tools to debug production.

Market Signal

Why It Has Market Pull

Respan (formerly Keywords AI, YC W24) is an established LLM engineering platform whose AI gateway unifies routing, observability, evals and prompt management; it has real funding, real scale, and a credible developer customer base. This is among the strongest builder-momentum signals in the set.

  • Earned 439 upvotes for the gateway launch on Product Hunt
  • Raised a $5M seed led by Gradient Ventures with Y Combinator participation
  • Processes 1B+ logs and 2T+ tokens per month, supporting 6.5M+ end users

Bond

643

Bond is an AI Chief of Staff for executives. It connects to your tools, learns how your company works, and turns scattered tasks into a self-managing to-do list that always knows what you need to do next.

Asmi AI

452

Asmi calls you every morning. You talk - it handles the day. It calls services (dentist, salon, plumber, bank, insurance) or people (friends, colleagues) to coordinate, book or resolve things. Updates you on iMessage or WhatsApp when done. It can navigate IVRS, wait on hold and handle complex conversations well.

Terminal Mode by Even Realities

400

Terminal Mode by Even Realities unlocks an ambient terminal on Even G2 smart glasses. When a coding agent stalls, you catch it: see which agent needs you now, give direction, and approve key steps while your laptop runs long tasks, so token-maxers get more from every run and vibe coders stay in flow.

Journey Now

Journey Now turns anything you want to learn or master into a personalized, step-by-step plan — with daily guidance, reflection, and a view of how friends are progressing too. As your pace or goals change, the plan adjusts itself, so progress never stalls on a missed deadline.

Slashspace AI

363

An AI native user today copy-pastes prompts across a dozen apps. It's a broken experience for any kind of meaningful work. Every new chat box collapses context to zero. Slashspace solves that with an AI canvas where AI lives on the canvas, and you can run many chats as nodes. The canvas becomes the context space, and all the agents can see each other. Canvas is stored as files on your computer. Built with 1600 power users for over 1.5 years, we're the most mature canvas AI on the market.

CrustRecruiter

226

Recruiting is half judgment, half grunt work. Claude brings the judgment, i.e. the reasoning and the memory, while Crustdata brings 800M+ candidate profiles and 5 recruiting skills via MCP, meaning the manual work runs itself and you get genuinely personalized recruiting at scale, all inside one chat.

Extend UI – open-source UI kit for modern document apps

We're open-sourcing 14 components & examples today for PDF, DOCX, and XLSX viewers, plus bounding box citations, file upload, e-signature, and more. It's MIT licensed and fully customizable. Demo video here: https://share.extend.ai/kRmSGKRF When we started, we tried every file viewer and document component library we could find.

HelixDB – A graph database built on object storage

150 pts

Hey HN, it’s been just over a year since we launched HelixDB ( https://news.ycombinator.com/item?id=43975423 ), a project a friend and I started in college. It’s an OLTP graph database built on object-storage, with native vector search and full-text search (FTS). Why graph, vector and FTS? Graph databases provide a natural cognitive model for data, vectors allow for a semantic understanding of the entities and relationships in the graph, and FTS provides more specific filtering. Many AI-driven a... (150 points, 42 comments).

On-device transcriber that's 97% accurate at identifying speakers

I’ve spent the last seven months building a tool I wish I’d had in my previous roles. MimicScribe is a macOS menu bar app that fits the "AI notetaker" category. It has accurate on-device speaker identification (a first possibly?), real-time meeting talking points for discovery calls, and a fully keyboard- and voice-driven interface. I believe the accuracy of the speaker ID system is its biggest strength. I used fluid audio’s port of ( https://github.com/fluidInference/FluidAudio ) Pyannote's com... (32 points, 10 comments).

Magenta Real-Time Music Generation Locally on iPhone, Without the GPU

Last Thursday, Deepmind released Magenta Realtime 2 , an open source music generation model. They said it could run on Mac, but not iPhone. As a v̵i̵b̵e̵ ̵c̵o̵d̵i̵n̵g̵ ̵a̵d̵d̵i̵c̵t̵ agentic AI maxxi and person who has melted iPhones before (link at bottom), I took that as a personal challenge and made it my weekend project. On Saturday, I got it to run for 10min straight on an iPhone 12 Pro from 2020 without melting the phone or - shockingly - touching the GPU. How? I chopped the model up into 5...

Workplane – collaborative files for agents (and humans)

8 pts

A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!
