It lives in your menu bar and slides in with a keystroke (⌘+/) even over fullscreen apps, so you can plan your day without losing your place. The core workflow is simple: open Chunk, drag tasks from your list onto the timeline to create time blocks, and apply recurring templates when a routine needs to fill the day. What sets it apart is two-way synchronization with the calendars you already use. Apple Calendar, Google Calendar and Outlook Calendar all stay in sync, and Apple Reminders can feed tasks into your day. Tasks, projects, smart lists and recurring templates live in one column, while the schedule can be viewed as a day timeline, a week grid or a month view, with optional PDF or CSV export. Chunk also includes a local MCP (Model Context Protocol) server for AI planning. Connecting it to Claude Desktop takes one click from Settings, after which you can manage events, tasks, projects and templates in natural language. Because the MCP server is a local process reading and writing directly to Chunk's on-device database, your data does not leave your Mac beyond what Claude itself processes. Chunk is a one-time purchase with a free trial, aimed at people who want deliberate daily planning rather than another subscription. **Pricing & Plans:** One-time purchase of $39.99 with no subscription. A 7-day free trial is available and does not require a credit card. Requires macOS 12 Monterey or later. - **Drag-and-drop time blocks:** Drag tasks from your list onto the timeline or apply recurring templates to fill your day with focused blocks. - **Two-way calendar sync:** Events sync both ways with Apple, Google and Outlook calendars so your plan and your real calendar stay aligned. - **Multiple schedule views:** Work the same plan as a day timeline, a week grid or a month view, and export to PDF or CSV when you need a copy. - **Projects and smart lists:** Treat lists as projects with an overview, deadline and finish line, and split large tasks into scheduled sessions. - **Local MCP server for Claude:** Connect Claude Desktop in one click and plan your day in natural language, with all reads and writes happening on your Mac. **Strengths:** One-time purchase with no recurring subscription; Two-way sync with Apple, Google and Outlook calendars; Local MCP server lets Claude plan your day without sending data off-device; Available instantly from the menu bar on any screen, including fullscreen apps **Limitations:** macOS only - no Windows, iOS or Android version; A one-time purchase means you rely on the developer for ongoing updates; Not a full team project management tool; focused on personal planning [Profile (Markdown)](https://openaitools.app/tool/chunk-1.md) ## LightPDF LightPDF positions itself as an all-in-one document workspace rather than a single-purpose converter. The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan. - **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos. - **Layout-preserving translation:** Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact. - **AI data extraction to spreadsheets:** Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically. - **Full PDF editing and conversion suite:** Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate. - **Cross-platform access:** One account works on web, Windows, Mac, iOS and Android, so documents and paid features follow you between devices. **Strengths:** Very broad toolkit that covers both everyday PDF chores and advanced AI document tasks; Free tier is usable for light jobs, and the paid plans are cheaper than many competing PDF editors; Layout-preserving translation and AI data extraction handle scanned documents that trip up simpler tools; One subscription covers five platforms, including desktop and mobile apps **Limitations:** Free plan caps files at 10MB and adds watermarks on some outputs; AI features run on a credit system, so heavy usage means top-ups or a higher tier; Advanced AI operations like text editing or logo removal consume credits quickly [Profile (Markdown)](https://openaitools.app/tool/lightpdf-com.md) ## Frequently Asked Questions ### How do Chunk and LightPDF compare in monthly traffic?
