📊 4 Rewrite Levels

From light touch-ups to complete rewrites, choose the level that fits your needs.

🎨 13 Tones

Professional, casual, academic, creative, persuasive, and more. Pick the tone that matches your content's purpose.

🥷 Multi-Pass Ninja Mode

Run multiple humanization passes for the most natural-sounding output. The ninja mode applies layered transformations to make text virtually indistinguishable from human writing.

🔓 No Login, No Limits

Zero friction. No account creation. No usage caps. Just open it and use it.

Tech Stack

Language: TypeScript
Architecture: Provider-agnostic plugin system
UI: Clean, minimal interface focused on usability

Why Open Source?

Text humanization should be accessible to everyone — students, content creators, developers, and researchers. Locking this behind paywalls creates an uneven playing field. StealthHumanizer levels it.

The hidden cost of GPT-4o: what every SaaS founder should know about per-user LLM spend it

So you're running a SaaS that leans on an LLM. You check your OpenAI bill at the end of the month, it's a few hundred bucks, you shrug and move on. As long as it's not five figures, who cares, right? Wrong. That total is hiding a nasty secret: you're probably losing money on some of your users. I'm not talking about the obvious free-tier leeches. I'm talking about paying customers who are costing you more in API calls than they're giving you in subscription fees. You're literally paying for them to use your product. The problem with averages Let's do some quick, dirty math. GPT-4o pricing settled at around $3/1M tokens for input and $10/1M for output. It's cheap, but it's not free. Say you have a summarization feature. A user pastes in

The Wrong Way to Use AI for Debugging (And the Mental Model That Actually Works)

Same AI tool. Same codebase access. Same staging incident. Three experienced engineers spent hours and couldn't find the root cause. I found it in about 20 minutes — and I barely knew what half the tools did. This isn't a story about juniors being better than seniors. It's about a mental model for AI collaboration that anyone can use — and why the "obvious" way most people use AI actually holds them back. <h2> The Incident </h2> A message hits the team Slack channel: <blockquote> "Staging is broken. We're investigating." </blockquote> The error: <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>alembic current ERROR: Can't locate revision identified by 'ba29cdc8739d' FAILED: Can't locate revision identified by 'ba29cdc8

Setting Up a Production-Ready Laravel Stack: Nginx, PHP 8.4, MySQL, Valkey & Supervisor

A Laravel application running on your local machine with <code>php artisan serve</code> and a SQLite database is a fundamentally different beast from a Laravel application serving thousands of requests per minute in production. The gap between development and production is not just about code. It is about infrastructure: a properly tuned web server, an optimized PHP runtime, a robust database engine, a fast cache layer, and a process manager that keeps your queue workers alive. Building this stack manually is a rite of passage for many developers, but it is also a minefield of configuration mistakes, security oversights, and wasted hours. Deploynix provisions this entire stack automatically when you create an App Server, configured with production-grade defaults that reflect year

Why AI Agents Need Both Memory and Money

Every major AI agent framework — LangGraph, CrewAI, AutoGen, Semantic Kernel — gives you the same primitives: tool calling, chain-of-thought reasoning, and some form of state management. These are necessary but not sufficient for agents that operate in the real world. Two critical capabilities are missing from every framework: cognitive memory that behaves like a brain and financial agency that lets agents transact. More importantly, nobody has connected the two. That's what MnemoPay does. <h2> The memory problem nobody talks about </h2> Current agent memory solutions (Mem0, Letta, Zep) treat memory like a database. Store facts, retrieve facts. This works for simple use cases, but it fundamentally misunderstands how useful memory works.</p

Show HN: AgentLens – Chrome DevTools for AI Agents (open-source, self-hosted)

Agents are opaque. AgentLens is Chrome‑DevTools for AI agents — self‑hosted, open‑source. It traces tool calls and visualizes decision trees so you can see why an agent picked a tool. Repo: <a href="https://github.com/tranhoangtu-it/agentlens" rel="noopener noreferrer">https://github.com/tranhoangtu-it/agentlens</a> It plugs into LangChain/FastAPI stacks, uses OpenTelemetry spans, and ships a React frontend (Python backend, TypeScript UI). You get per-tool inputs/outputs, timestamps, and branching paths — the raw traces you actually need to debug agents. Practical playbook: emit spans from your agent, sample 100% in dev, 1–5% in prod. Persist traces off your user data store (filter PII). Watch for repeated tool calls, backoff loops, and input drift. AgentLens gives visibil

I Built a Social Post Engine to Escape the Canva-Export-Schedule Loop

As a solo founder running WahResume.com, I was spending way too much time on social media - not on creativity, but on process. Same templates. Same brand assets. Same hashtags. Every post meant opening Canva, exporting, uploading, scheduling… and repeating it the next day. So I built something to fix that. Social Post Engine is a small tool that helps me stay consistent on social media without having to touch Canva or an endless queue of schedulers. Here’s what it does: ✅ Seed & review topics in one command — it researches, outlines, and preps your next posts. ✅ Pre-generates branded images from templates (checklists, stat cards, charts, comparisons). It also writes captions in your brand’s voice using AI. ✅ Publishes automatically to LinkedIn
