pen.dev

By pen.dev

pen.dev is an infinite-canvas design editor for websites, app screens, dashboards, slides and marketing graphics. This plugin opens the editor right in the conversation, so Codex designs on a live canvas while you watch: it lays out screens, builds reusable components and variables, and refines what's already there. Designs are saved as .pen files in your workspace, next to your code, ready to commit and to turn into code. Select anything in the editor to point Codex at it, and sign in to pen.dev to let Codex generate AI and stock images and vector artwork.

By Paloma Maceetko

Pensieve is a free notes app with reminders.

pickthehotel

pickthehotel

By SYLVAIN CHRISTOPHER ALEXANDER GORDON-HORWOOD

pickthehotel is an answer engine for hotels. Instead of a wall of results, ask for the one hotel that fits your intent in a city and get a single confident pick, a few alternatives, and a booking link. Choose an intent: • iconic - the standout in town • value - great, and fairly priced for what you get • budget - cheap, clean, and genuinely central • family - one room that actually sleeps two adults and the children Every hotel is judged the same way - value (punching above its price), location (closeness to what you actually came for), and reviews (weighted by confidence, not just averaged) - with no paid placement. You can anchor "central" to a landmark ("near the Louvre") or to your live location, and you can ask for a curated list of long-established hotels around the world. Live in Zürich, Paris, London, New York, Tokyo, Bangkok, Dubai, Singapore, Istanbul, and Hong Kong, with more rolling out. Prices are indicative and confirmed at the booking site; booking links are affiliate and disclosed.

poste — Slovenian post offices

poste — Slovenian post offices

By Temno Modro d.o.o.

poste is an independent, unofficial service by poste.cc — not Pošta Slovenije and not affiliated with it. It brings Pošta Slovenije's post offices, parcel lockers (paketomati) and street mailboxes into ChatGPT — the same data as poste.cc. Ask "is the post office in Koper open now?" or "which post offices in 1000 Ljubljana are open on Saturday?" and ChatGPT finds the branches and reads their opening hours with Slovenian public holidays applied. - Search post offices, parcel lockers and mailboxes by place, postal code, branch code, address or nickname - Find the nearest post offices, parcel lockers and mailboxes to a location, with distance - Get one post office's hours for the next 7 days, whether it is open now, on-duty and mobile post office schedules, services, phone numbers and nearby alternatives Every result links to the full page on poste.cc. Read-only, no account needed. Works in English and Slovenian. Limitations: covers Pošta Slovenije in Slovenia only — no parcel tracking, postage prices or mailbox collection times. poste.cc is unofficial and not affiliated with Pošta Slovenije.

protogrid.dev

protogrid.dev

By Pedro Ibáñez Requena

protogrid is a public registry of MCP servers. Describe a task in plain words and it finds matching servers from the official MCP registry, tells you how each one connects (no sign-in, an API key, OAuth or a local package), and returns a ready-to-use configuration for clients such as Claude Code, Codex, Cursor or VS Code. Every server shows its tools, a change history of its tool definitions, and trust and quality scores built from our own credential-free checks. You can also check any remote MCP server URL for protocol support and directory readiness. protogrid is read-only: it never calls third-party tools and never asks for your credentials. Scores come from observable signals; no audit is implied.

By National Digital

Australian government open data republished as CSV, Excel, JSON, Parquet, SQLite, Arrow, GeoJSON and GeoPackage at URLs that never change. Every release is a dated, immutable version with schema, provenance and a diff. Run by National Digital. No government agency has endorsed it. Tools: - Search datasets: Find the slug of a served dataset. - Read a dataset: Read a served dataset's data package and full version history. - List a dataset's fields: List a served dataset's fields, with their types, descriptions, ranges and values, before querying it. - List partition files: List the download files that split a served dataset's newest version by one field, such as one file per year. - Query rows: Read individual rows of a served dataset, filtered across the whole table. - Count and sum rows: Count, sum, average, minimum or maximum rows of a served dataset across the whole table, grouped by up to three fields. - Compare versions: Compare two consecutive versions of a served dataset row by row on its key fields, to see what a publisher changed between releases. - Search government portals: Search every dataset listed on Australia's government portals, including the many publicdata.au does not serve yet. - List the build backlog: List the datasets people have asked publicdata.au to build, most votes first. - Vote for a dataset: Add one anonymous vote for a government dataset that publicdata.au does not serve yet, so it is built sooner. The fields of one dataset by slug: types, the publisher's descriptions, ranges and the values each field holds. Find slugs with search_datasets or resources/list. The MCP server records nothing about who calls it or what they ask. To keep the rate limit, it counts row tool calls per address in Cloudflare's cache for 10 seconds.

qlaris

By Qlaris

Qlaris brings user research into Claude. Ask a product question and get evidence back in the same conversation: run surveys, 1:1 interview studies, moderated focus groups and user tests of a website or prototype on calibrated AI customer panels for the US and 39 European countries. Then read the answer distributions, findings with verbatim quotes and user-test reports, each with a link to the study in the Qlaris app. What you can do: - Draft a survey or an interview study from a research question and review it before anything runs. - Test a live website, or a prototype you publish from Claude, and see where participants get stuck. - Run surveys, interviews and focus groups with the audience you choose: a saved persona, a segment or panel filters. - Ask questions of the research your team has added to Qlaris and get sourced answers, checked for freshness and conflicting findings. - Check how far a research question or a finished study can be trusted, and request research with real human respondents when a question needs it. - Manage personas, workspaces and workspace context. Studies use validation units your Qlaris account already holds; nothing can be bought in Claude. Every tool that launches a study, spends units or changes your workspace asks for your confirmation first. Results come from synthetic respondents (digital twins): they complement research with real people rather than replace it. Built for product managers, UX researchers and innovation teams who want evidence behind product decisions.

qrforprint

qrforprint

By Digimental Teknoloji A.Ş.

qrforprint is a QR code generator for print. With this connector, Claude can: 1. Preview a static QR code for a web address, plain text, email, phone call, text message, WiFi network or contact card. Claude shows the image and a link that opens the same content in the qrforprint editor, where it can be styled and downloaded as PNG, SVG, PDF or EPS. No account is needed and nothing is saved. 2. List the QR codes in your qrforprint account with their short links, destinations and scan counts. 3. Create a dynamic link QR code. The printed code holds a short link, so its destination can be changed later without reprinting. 4. Change where a dynamic link code goes. Claude asks you to confirm before anything changes. The connector cannot delete codes, upload files, take payments or see payment details. Free accounts include unlimited static codes and 3 dynamic codes; Pro ($9 a month) removes the dynamic code limit. Photo, PDF and voice note codes are created on qrforprint.com. Sign in is needed only for the account tools, and Claude asks for it the first time one of them is used.

qrlia is a white-label QR code platform hosted in the EU. Connect your workspace and ask Claude to create dynamic QR codes (URL, vCard, Wi-Fi, menus, landing pages and more), change where a printed code points, organise codes in folders and designs, and read scan analytics by day, country, device and referrer. Every action runs as the signed-in user with their current role; admin actions (members, custom domains, webhooks, API keys) need the separate admin scope, which only workspace admins can grant. Destructive tools are marked as such, and codes keep redirecting after a downgrade or cancellation.
