An official MCP server lets Claude Desktop and Claude Code search the catalogue in natural language. Free sign-up, no commitment, no credit card.
Why we built LemongraphI have been rethinking personal task management for a long time.As a leader, my work lives mostly in conversations with my team, my manager and people outside the company. Each one ends with a promise or action items and keeping them is most of how people experience working with me.My answer was a personal to-do list, but staying consistent became a job of its own. That effort felt like the price of being good at work.But most of my work is already written down in emails, meeting notes, tickets, CRM and Slack. So what if, after every conversation, the action items simply appeared on my list? What if something kept track of the promises I made and the ones made to me, watched the signals around me and every morning helped me decide what matters today?That is why personal task management needs to be reimagined. Not the smartest agent, the one that books your flights. Something smaller and more personal, a way to show up as the better version of yourself more often.If you have tried to automate your own to-do list and given up, I would love to hear what made you stop.How it worksWe noticed something about our own workdays. Almost every conversation ends with a promise. Keeping up with all of them slowly becomes a job of its own.What if personal task management took on that job? Picking up action items, watching signals and prioritizing the way you would.So we built Lemongraph to take that job off your plate. It picks up what you promised in meetings and email and lines it up in Up next. By the time you sit down your day is already sorted the way you'd sort it yourself.It also pays attention to how you work with the people around you. Every day it reflects a little and gets a little better at being you.We don't work alone. Our assistants shouldn't either. Lemongraph pays attention to how we work with our colleagues, managers and people outside of the organization, across Gmail, Linear, Attio and more. Then it reflects on it and gets a little better at being us every day.Some work you do over and over. The kind you'd happily hand to someone if you had someone. When Lemongraph spots one of those chores it shows up with a Hire button. Say yes once and next time it just asks for your OK.You won't find a chat box anywhere. You don't have to prompt it or explain yourself. It just learns your context and brings up what matters right when it matters.And it will never surprise you. Every action waits for your yes until you decide it doesn't have to.We hope it gives you back a bit of your day.IntegrationsGmail, Google Calendar, Google Drive, Google Tasks, Cal.com, Calendly, Granola, Wispr Flow, Notion, Linear, Asana, ClickUp, Monday.com and Attio.PricingFree to start.

LensUp Scanner is a free, browser-based document scanner that turns phone photos into clean, printable PDFs and includes ID-card copy and PDF tools; the free tools process your files on your device. To scan, take a photo of a page with your phone, then crop it, correct the perspective and remove shadows so the page comes out flat and even. You can scan several pages in a row and save them together as one multi-page PDF. The ID-card copy tool places the front and back of a card on a single printable sheet. For documents you already have, there's a PDF editor along with tools to merge several PDFs into one and to add a signature. Everything opens in the browser, and every tool is free.

BskyDelete is an account-cleanup and management tool for Bluesky, designed for people who want to reduce their public history or reorganize their social activity without abandoning an existing profile. It supports bulk deletion of the user's own posts, removal of likes and reposts, and bulk unfollowing of selected accounts. This makes it useful for people cleaning up old conversations, creators updating a public brand, and professionals reducing outdated online activity.The workflow emphasizes control before deletion. Users sign in to BskyDelete, connect their Bluesky profile using official AT Protocol OAuth, choose the relevant content type, and filter results. Depending on the operation and plan, filters include date range, keywords, author or content signals, and engagement metrics such as like or repost counts. The dashboard lets users inspect matching items and make the final decision. Selected posts, likes, reposts, or following data can be exported to CSV where supported, helping preserve a record before cleanup.For privacy, BskyDelete does not ask for the Bluesky password. The OAuth client manages authorization through the browser using the official protocol. Users retain control of their selections, and permanent deletions should be reviewed carefully because they may not be recoverable. It is a web app rather than a Chrome-only extension.The Free plan offers up to 30 deletion or unfollow actions per day with basic date filtering, likes/reposts cleanup, and community support. Monthly Pro is $12 per month. Yearly Pro is $60 per year. Paid plans remove BskyDelete's own daily deletion quota, unlock advanced filtering, bulk unfollowing, export-before-delete, and priority support. Bluesky API rate limits can still apply even on paid plans.

Track Vacations is a simple and organized way to schedule time off for team members. You create your team's private calendar in a minute: give it your company's name, choose what you call your team members, pick how many months to show and a light or dark theme, and get a secret link to share with the team. Anyone with the link adds vacation days by choosing a name and picking a date or dragging across a range, and everyone sees the months ahead side by side. Notifications in Slack or Discord tell the team when someone schedules time off. There is no account to create and nothing to install. It is free, and it suits small teams, startups, agencies and remote teams that want a shared view of holidays and days off without a spreadsheet nobody updates or an HR system too big for a team of ten. Track Vacations does one job, showing who is away and when, and keeps it simple enough that people actually use it.
