Design vector graphics with AI text-to-SVG generation and multi-format editing in your browser.

I think I may have finally found a fully free alternative to BoxySVG. I came across this browser-based free SVG editor from svgmaker , and it feels pretty close to Apple Freeform in the way the canvas, grids, snapping, and alignment work. It also lets you edit paths, points, text, colors, shapes etc. Most of the things I used to open BoxySVG for, I can now do in this one—and it’s completely free. Honestly, I wasn’t expecting it to be this capable, especially since most AI image generation

I asked ChatGPT 20 different ways who could fix a half-built app. It never named my company once. I do codebase rescue for founders in exactly that spot, so that one stung. There are already plenty of tools that measure this kind of AI visibility, a CDN even ships one free, so I built mine mostly to see my own number, and it confirmed the bad news: near zero. The measuring turned out to be the easy part. What none of the tools do, and what I actually care about, is the fix: getting the mode

Free consumer product, seat-based education product, enterprise assessment product. Same codebase. Is this survivable? Three motions off one core. Students practice free and generate cost, not revenue. Educators pay per seat. Hiring teams are the expensive product and the reason any of it matters. The free tier feeds both paid ones and that's the only thing justifying it. Education is slow, cheap, sticky. Hiring is faster, pricier, and churns the second the role gets filled. Billing got

We rebuilt Sentimentor 2.0 around asking traders what sucks about their market research and trading platform. Greetings Everyone ! Sorry for the long post but I appreciate your time in advance. Back in March 2026, our team launch sentimentor.ai - a market data and sentiment analysis platform. Since then, we have reached out to users from different subreddits asking what is the biggest pain point they have seen in using the platform of their choice. Even though everyone had

Maps your codebase and cloud infrastructure into architecture diagrams with AI analysis.

The real challenge with vibe coding isn’t generating code—it’s staying able to understand the system as it evolves. Making architecture, dependencies, and workflows visible can help fight code slop. That’s what we’re exploring with JigsawML. Free demo:

I have rebuilt the Markdown to PDF converter on You paste your text or Markdown, you get a properly typeset PDF back, and your AI agent can do the same over MCP or a plain API call. No sign up, no key, free. Had built this a long time back as a fairly basic thing and then left it alone, and over the last few weeks I could see a rise in traffic. Took a fresh look and found that lot of it was not rendering. Headings below a certain level were being dropped, nested lists were coming out flat, and code blocks were losing their formatting. What is there now: - Page breaks where you want them, using :::pagebreak::: on a line by itself - Tables, nested lists, task lists and code blocks all render properly - Greek letters, maths symbols, arrows and the rupee sign come out right - Emoji and symbols do not break the render - Plain dot txt files keep their line breaks Live tool at API & MCP docs (humans): API & MCP docs (AI)
