Companies use AI to take your calls. I built AI to make them for you #

pipervoice.com faviconpipervoice.com
176 комментариев10:17 PMПосмотреть на HN
We're living in this weird asymmetry where companies use AI to talk to us, but we're still manually dialing them. Companies everywhere are adopting AI voice agents lately. Big retail, family dentist clinics, local pharmacy. This year, I've been in a few calls where it's super natural sounding AI, which has been pretty cool to experience. But then it got me thinking - why are we, the consumers, still the ones making calls if they're using robots for theirs?

So I built Piper: basically AI that makes phone calls for you. You tell it what you need (book appointment, check on an order, dispute some charge, whatever), and it handles the entire conversation while you do actual work. Right now it's a web app, Chrome extension is pending approval but soon you'll be able to click any phone number anywhere and just let Piper handle it.

Technical stuff that was harder than expected:

Latency - every millisecond counts in conversation, had to optimize around kv cache, got it down to ~1000ms to first word over PSTN for telephony, which feels pretty natural

Keeping the voice agents on track - built custom context engineering logic that constantly updates the agent's situational awareness, so it knows when it's been transferred, when it's on hold, etc

Done ~50 successful calls with early testers so far. Main failures are when they need complex verification or documents. Also had to take down our IVR navigation temporarily :/, found some edge cases that were causing unnecessary transfers but working on fixing that.

I really think we're heading toward this world where AI talks to AI for most routine things, and phone calls might be the first real example of this happening at scale!

Hi HN!

I wanted to make some photomosaics for an anniversary gift, but I ended up building this tool and turning it into a free website that anyone can use.

For those who don’t know, a photomosaic is an image made up of many smaller tile images, arranged in a way that forms a larger, recognisable picture.

The best part? Everything runs directly in your browser. No files are uploaded, and there’s no sign-up required.

Kiln – AI Boilerplate with Evals, Fine-Tuning, Synthetic Data, and Git #

github.com favicongithub.com
1 комментариев7:14 PMПосмотреть на HN
I noticed there weren't boilerplates for AI projects like there were for web apps, so I built one. Same idea - everything you need to get a project up and running quickly. However, instead of web-framework/CSS/DB, it's tools for AI projects: evals, synthetic data gen, fine-tuning, and more.

Kiln is a free, open tool that gives you everything most AI projects need in one integrated package:

- Eval system: including LLM-as-judge evals, eval data generation, human baselines

- Fine-tuning: proxy to many fine-tuning providers like Fireworks/Together/OpenAI/Unsloth

- Synthetic data generation: deeply integrated into evals and fine-tuning

- Model routing: 12 providers including Ollama, OpenRouter, and more

- Git-based collaboration: projects are designed to be synced through your own git server

The key insight is that these tools work much better when they're integrated. For example, the synthetic data generator knows whether you're creating data for evals vs. fine-tuning (which have very different data needs), and evals can automatically test different prompt/model/fine-tune combinations.

It runs entirely locally - your project data stays in local files, and you control your own git repos. No external services required (though it integrates with them if you want).

Main project GitHub: https://github.com/Kiln-AI/Kiln

Demo GitHub where I use it to build a 'natural language to ffmpeg command' demo with evals, fine-tunes, and synthetic data (including demo video): https://github.com/Kiln-AI/demos/blob/main/end_to_end_projec...

I built a free tool to find valuable expired domains using AI #

pendingdelete.domains faviconpendingdelete.domains
7 комментариев4:25 PMПосмотреть на HN
Hi HN,

I’ve been collecting and analyzing expired domains for years — especially those about to drop. Every day, tens of thousands expire. Most are junk, but a few still have traffic, backlinks, SEO value, or just great names. Finding them used to take hours.

Last week I put my internal tools online: https://pendingdelete.domains No login, no paywall Updated daily Combines domain history, traffic, SEO data and AI-driven insights to identify valuable expirations The goal: help spot valuable domains quickly and skip the noise.

Still a work-in-progress — would love feedback: Is this useful? What signals or filters would you add? Any UI or speed improvements?

Thanks!

A semantic code search tool for cross-repo context retrieval #

github.com favicongithub.com
0 комментариев3:15 AMПосмотреть на HN
I’ve been frustrated trying to get the right context when working across multiple repos in AI assisted software development.

So over a weekend, I built h‑codex – a tool that can pull context from scattered repos into Cursor / Claude Code (integrated via MCP); ensuring that they’ve got the full picture when doing the plans/implementation.

How it works:

- Indexes the repos - Chunks code with AST for optimal chunk boundaries - Generates embeddings and stores them in pgvector for fast semantic search

Check it out: https://github.com/hpbyte/h-codex

Hi HN,

I’ve been working on a side project called SocialKit, a simple API for scraping structured data from public social media posts (YouTube, Shorts, more coming soon).

It's designed for dev, no-code users, and marketers who want to extract things like summaries, transcripts, details, and more from YouTube.

I sold two previous side projects (LectureKit and CaptureKit), and this is my latest attempt at building something useful and focused. I would love to get any feedback :)

Happy to answer any questions, and thanks for checking it out!

Stop the '+1' Spam: Automatically Filter GitHub Comment Noise #

2 комментариев8:25 AMПосмотреть на HN
https://gist.github.com/freakynit/1f472c92e01f7e77287c727c6d...

GitHub issues for popular projects are often flooded with "+1”, "Me too”, and other unhelpful comments, making real discussions hard to track. This is a simple Google Apps Script (taking reference from https://github.com/cline/cline/discussions/581#discussioncom...), which scans your Gmail inbox for emails triggered by these "noisy” comments and automatically trashes them.

Also accompanying (as comment below the script) is browser console script to dim or hide these comments from issue discussions.

AllEars – Automate Your Phone Based on Sounds (Offline, No Cloud) #

play.google.com faviconplay.google.com
0 комментариев7:52 AMПосмотреть на HN
Hi HN,

I built AllEars, an Android app that listens for real-world sounds — like snoring, coughing, barking, alarms, glass breaking, and more — and lets you automate actions on your phone using simple IF–THEN flows.

It runs fully on-device, with no cloud, no mic streaming, and no internet requirement. Your phone detects sound events locally using TensorFlow Lite (YAMNet) and executes your defined actions.

Examples:

IF snoring AND coughing THEN vibrate + log timestamp

IF glass break THEN trigger webhook

IF dog bark OR doorbell THEN send notification

Each flow uses flat AND/OR logic, supports multiple actions, and can include time filters. The app runs as a low-power background service with a persistent notification for transparency.

Available actions:

- Play a sound

- Vibrate

- Send a notification

- Log a timestamp

- Trigger a webhook

Why I built it: I wanted user-programmable automation driven by ambient sound — without sending any audio to the cloud.

Think of it as IFTTT for offline sound events.

Try it on Play Store: https://play.google.com/store/apps/details?id=com.cliqueraft... — no signup needed. Free plan includes 3 flows.

Looking for feedback on:

1. What sounds would you want to detect and respond to?

2. What other actions/triggers would make this genuinely useful (keeping things offline and safe)?

3. Any UI feedback on the flow builder logic?

Thanks! Happy to dive into anything technical

0 комментариев4:44 PMПосмотреть на HN
I work at Font Awesome (YC 2015) and we recently launched Font Awesome 7, including hundreds of new icons, a fresh visual redesign, and better perf.

Fun fact: Font Awesome icons are viewed 6–8 TRILLION times per month, so we have a pretty good idea which ones are used the most! Armed with this knowledge, we added seven entirely new icon packs, each with 200+ of the most frequently used icons in their own unique designs.

What's new in v7:

- 300+ new icons

- Redesigned core icons for better visual consistency, clearer shapes, and smoother outlines

- The Icon Wizard now supports over 40 modifiers and can instantly convert modified icons into Duotone

- Better rendering and file loading

- Seven new Pro+ icon packs: Chisel, Etch, Jelly, Notdog, Slab, Thumbprint, Whiteboard, and more on the way

Head to https://fontawesome.com/ to browse all of the new icons and styles.

We love feedback and I'm happy to answer any questions about the release, the tech behind it, or icon design in general! (Note that I primarily work on a sister product called Web Awesome, so it might take me a little time to reply if I have to ping a colleague about a specific question!)

I added webhook response support for MCP tool calls in asyncmcp #

github.com favicongithub.com
0 комментариев9:06 PMПосмотреть на HN
Building on asyncmcp, a library for custom transport layers for Model Context Protocol (MCP), I added a custom transport for webhook support that lets MCP server tools respond asynchronously via webhook. When async marked tools are called, the result gets sent to the registered endpoint instead of blocking the connection.

This is still experimental but provides a way to add webhook support to MCP. You can clone the repo and try the streamable_http_webhook examples.

Running Claude Code using any LLMs? Here's an open-source tool for it #

github.com favicongithub.com
0 комментариев10:13 PMПосмотреть на HN
We recently built something useful if you want to run Claude Code with any LLMs. Forge is an open-source API layer that lets you mix Claude Code with any model – OpenAI, Gemini, Qwen, Moonshot, etc. Full flexibility without changing your app logic. You can mix-and-match models however you’d like.

Our demo runs:

Gemini 2.5 Flash as the fast, lightweight model

Qwen3-Coder-480B as the more powerful planner and code generator

But you can configure whatever combo works best for your use case. Forge offers better performance, lower costs, and full control with self-hosting options.

You can find our quickstart repo here: https://github.com/TensorBlock/claude-code-forge

Would love to hear your thoughts on this!

Side Reader is a Chrome extension that lets you read and interact with PDFs directly on ChatGPT, Claude, and DeepSeek websites.

I built Side Reader because I got tired of the constant tab-switching between PDF readers and AI chat - copying text, switching tabs, pasting, repeat. It was driving me crazy.

Over time, I added more features like custom highlight buttons, screenshot functionality, and local storage.

ClearDoc – Extract fields from any document using OCR and LLM #

cleardoc.v5ent.com faviconcleardoc.v5ent.com
1 комментариев12:50 PMПосмотреть на HN
Hi HN!

I recently launched a prototype of *ClearDoc*, an AI-powered tool to extract structured data from unstructured documents like invoices, bills of lading, certificates, etc.

It uses *OCR (PaddleOCR)* and *LLMs* to detect and align key fields — even for complex documents with tables, nested fields, or in different languages.

It doesn't require templates and can be *self-hosted* (demo runs on my own GPU).

Live demo (no sign-up): http://cleardoc.v5ent.com/ Demo video: https://www.youtube.com/watch?v=u83T6iewfNs

Right now: - Fields are auto-aligned visually on the document - Works with PDFs, images, scans - No custom field design/editing in the demo yet

Would love feedback on: - Which use cases matter most to you? - What would make this valuable enough to adopt?

Thanks!

I built a tool that turns OpenAPI specs into an agent #

pitch31.ai faviconpitch31.ai
0 комментариев4:29 PMПосмотреть на HN
Hey everyone! A couple of weeks ago I was exploring how to integrate multiple LLMs into one project, and I had this idea: what if I could leverage AI to interact with APIs in natural language?

After chatting with my cofounder, we were both intrigued. So I opened up Cursor and hacked together a prototype. After a few iterations, we had a working alpha: by dropping an OpenAPI file, we were able to get an AI Agent that understands it and can call those APIs using natural language. The Agent understood every prompt, made the right API calls and even auto-corrected bad payloads.

For internal APIs, auth is always tricky, so we added a system that supports API keys and credentials client-side only. Tokens are never stored on our backend. We also integrated it with Postman, so you can easily import your collections.

We imagine different use-cases and plan to add integrations (Stripe, Slack, CRMs, etc) and allow users to embed it where they want (for example on their platforms, so that their end-users can chat with the APIs and perform actions).

Looking for early users and feedbacks.

PayRankJobs – AI matches your resume with the highest-paying jobs #

payrankjobs.com faviconpayrankjobs.com
0 комментариев12:47 PMПосмотреть на HN
Hi HN! Solo founder here. Built PayRankJobs (https://payrankjobs.com) after my (tech writer) wife kept getting spammed with $55K job "opportunities" when she's already making $200K.

What it does: - Upload your resume.

  - Set your minimum salary requirement (optional).

  - Get an email with personalized job matches that actually pay well.

  - Includes AI-researched salary data (base + equity) and company ratings

Technical stack: - Serverless on Cloudflare Workers

  - LLM for resume parsing

  - LLM for embeddings/matching

  - PostgreSQL + pgvector for similarity search

  - Dynamic job fetching via Google.
Key differentiator: Instead of browsing endless job boards, the system finds YOU the highest-paying roles. No more wasting time on jobs that don't meet your salary requirements.

Currently works for all english speaking countries (not just US) and provides salaries in local currency.

I haven't figured out monetization yet - currently burning through my own money on API costs. Would love ideas on this. Some thoughts: - Charge job seekers after X matches?

  - Recruiting/sourcing tool for companies?

  - Premium features (more frequent updates, salary negotiation tips)?

I'd love feedback on:

  - The onboarding experience

  - Email format/content

  - What other features would be valuable?

Happy to answer any questions about the implementation.
