Show HN: PolyGPT – ChatGPT, Claude, Gemini, Perplexity responses side-by-side
I built PolyGPT to solve a problem I had: constantly tab-switching between ChatGPT, Claude, and Gemini to compare their responses.
It's a desktop app (Mac/Windows/Linux) that lets you type a prompt once and see all three AI models respond
simultaneously in a split view. Useful for:
- Comparing technical explanations
- Getting multiple perspectives on code problems
- Fact-checking answers across models
The app is free, open source, and runs locally - your credentials stay on your machine.

Show HN: Alera – Build and Deploy Your Own Private AI Stack in Minutes (MVP)
Problem: Companies want to use AI internally but can’t send sensitive data to cloud LLMs or afford the time and complexity of wiring together their own on-prem stack.
Solution: Alera gives you a browser-based workflow that generates a complete private AI deployment package you can run inside your own environment.
Why this approach: Instead of offering another YAML template or model wrapper, Alera builds the entire micro-infrastructure for you, including model serving, vector DB, security policies, and runtime wiring. You get a functioning private AI environment instantly.
MVP: The first version lets you pick an open-source model, choose use cases like Code Copilot or Document Insights, set runtime options, and download a ready-to-run Docker package containing Alera Core API, model server, and vector DB. It is designed to simplify private AI deployment for teams that need on-prem, compliant, or air-gapped setups.

Show HN: Compare Word documents in the browser (client-side only)
I built this after almost losing a client because we couldn't agree on which contract version was "final."
The problem with existing tools: • Word's "Track Changes" only works if someone remembered to turn it on. • Online comparison tools often require uploading sensitive legal/financial docs to their servers. • Desktop software is often bloated, expensive, or platform-specific.
My solution: • 100% Client-Side: Your files never leave your device. No server uploads, no database storage. • Format Support: Works with Word (.docx), PDF, Excel, PPT, TXT, and CSV. • Smart Parsing: I wrote custom parsers to preserve table structures and layouts during comparison (so complex contracts don't turn into a mess). • Zero Install: Works on any device with a modern browser.
Technical stack: • Next.js & React for the frontend. • Web Workers for handling heavy parsing tasks (like PDF rendering) without freezing the UI. • Mammoth.js & PDF.js for document text extraction. • Pure client-side diffing algorithms optimized for performance.
I'd genuinely appreciate feedback on:
Parsing Accuracy: How well does it handle your complex Word tables? (I spent a lot of time on the rowspan/colspan logic!) UI/UX: Is the side-by-side comparison intuitive? Performance: How does it feel with larger documents? Happy to answer questions about the implementation or discuss the tradeoffs of building a serverless document tool!
