Collecte MTL
By Sebastien Castiel
Collecte MTL tells you when your waste is collected anywhere on the island of Montréal. Enter an address and get the pickup schedule for every stream — garbage, recycling, food and organic waste, green waste, and bulky items — including the next upcoming collection dates for that exact sector. It can also point you to the nearest écocentres (drop-off centres) for materials that aren't picked up curbside, and show your borough's waste recovery and diversion rates. The data comes straight from the City of Montréal's official open data (Secteurs Info-collectes), refreshed about once a month. Collecte MTL is a free, independent tool — not affiliated with the City of Montréal — and stores no personal information: an address is used only to look up its collection sector.

Color Designer - Palette Maker
By Widget
Get perfect color ideas in seconds. Ask ChatGPT to suggest colors that work well together, then see them as a simple palette you can use right away. You can keep the colors you like, remove the ones you do not, change any color, or add new ones. The goal is to help you move from an idea to a useful color palette without getting stuck or spending a long time making small choices. Every suggested color appears as a large color tile that is easy to see. If a color does not fit your project, tap the remove button. Want another idea? Add a new color. Need to fine tune a palette? Change a color instead of starting over. You stay in control while ChatGPT helps you explore new combinations. The result feels fast, simple, and playful, even if you have never worked with color before. The app is made for anyone. You do not need to know color theory. You do not need to remember color names or search through huge lists. Just describe what you want, let ChatGPT suggest a palette, and make small edits until everything looks right. It works well for beginners, designers, artists, students, teachers, developers, and anyone making something that needs good colors. A simple editing flow keeps everything easy to understand. Each color is shown as a big square so it is easy to compare with the others. The remove button is always nearby, making it clear how to take a color away. An empty tile with a plus sign lets you add another color whenever you want. Because every action is visible, you always know what to do next. This makes the app useful for many kinds of projects. Build a brand palette. Pick colors for a website. Try ideas for a mobile app. Match colors for a game. Create art. Plan a room. Design a poster. Choose colors for a presentation. Make social media graphics. Find colors for invitations, stickers, shirts, or school projects. Even if you only want a fun mix of colors to inspire you, the app can help. ChatGPT can suggest calm colors, bright colors, warm colors, cool colors, playful colors, elegant colors, nature inspired colors, seasonal colors, or almost any style you can describe. If your idea changes, simply ask for another direction and keep editing until the palette feels right. You are never locked into the first answer. Because the palette is interactive, experimenting is easy. Swap one color instead of replacing everything. Keep your favorite shades while trying new accents. Remove colors that feel too dark, too bright, or too similar. Add another color when the design needs more variety. Small changes can quickly lead to a palette that feels balanced and complete. The clean layout helps you focus on the colors instead of extra menus or complicated tools. Large color blocks make differences easy to spot. Clear controls reduce confusion. The interface encourages trying new ideas because changing your mind only takes a tap. The app is also a great way to learn. As you explore different palettes, you naturally see how colors work together. You begin to notice contrast, harmony, and balance without reading long lessons. Every new suggestion is another chance to discover combinations you might never have picked yourself. Whether you already know exactly what you want or you are starting with nothing but a simple idea, this app helps turn words into color palettes that are easy to edit, easy to understand, and ready for your next creative project. It combines ChatGPT’s ability to generate fresh ideas with a straightforward editing experience, making color selection feel less like work and more like play.

Commonlands Optics: M12 Lens and C-Mount Lens Finder + Field-of-View Calculator
By Commonlands Optics
The Commonlands MCP server connects your AI assistant directly to Commonlands lens data, optics calculators, and live product details. This way your assistant can correctly calculate field of view with distortion instead of guessing, incorrectly interpolating, or writing it's own script. Built for machine vision, embedded vision, robotics, and industrial imaging, the server exposes 22 tools for M12 lens (S-mount lens) and C-mount lens selection. Your assistant can search the lens catalog, match lenses to specific image sensors by active area and image circle, run Commonlands field of view (FOV) calculations, estimate effective focal length (EFL) and pixels per degree, find distortion, and compare candidate part numbers. Ask it the way you would ask an applications engineer: Find M12 lenses for a 1/2.8" sensor at ~80 degrees horizontal field of view, then verify with the Commonlands field of view calculator. Compare two part numbers for a robotics camera: M12 mount fit, C-mount alternatives, FOV, and low-distortion options. Recommend low-distortion machine vision lenses for a 1/1.8" sensor. Every answer is source-labeled: fixture catalog, Commonlands calculator, live product read, cart handoff, or engineering review. Before showing any product URL, price, inventory signal, or variant, the assistant reads live Shopify product data, so specs stay accurate. Commerce is safe by design. Cart tools create, read, and update a cart only after you confirm exact line items and quantities, then return a continue URL for human review and payment. Checkout and order creation are intentionally disabled: the assistant cannot pay, place an order, or bypass storefront review. Connect in seconds, no OAuth or API key required: URL: https://mcp.commonlands.com/mcp Works with Claude (web, desktop, mobile), Claude Code, Cursor, Continue, Zed, and any MCP client. Commonlands provides precision M12 lenses and C-mount lenses for machine vision, with same-day shipping from San Diego.

Companion.energy is an energy-optimization platform for commercial and industrial sites. This connector gives your assistant secure, read-only access to your organization's data across: • Assets & locations — batteries, solar, grid connections, EV chargers and more • Sensor time series — consumption, production, power, state of charge and temperature, both raw and aggregated • Cost, revenue & savings — energy cost breakdowns, revenue, and realised savings • Market data — day-ahead spot prices, imbalance prices and metrics, and futures curves across European markets • Steering & flexibility — capacity under active energy-steering control • Forecasts, energy balance, profiles, spot exposure, imbalance, hedge positions and peak consumption Ask questions like "Show hourly consumption for the Antwerp plant last week and highlight the peak," "Break down energy cost by site for Q2," or "What were yesterday's Belgian day-ahead prices, and when was the cheapest hour?" The assistant retrieves the answer live and can also run its own read-only queries against the full analytics schema for anything the curated tools don't cover.
