Smallpdf is an online set of PDF tools, with thirty entries covering compression, conversion, organising, signing and asking questions of a document. The free tier runs every tool but caps how many results you take away, while Pro lifts the cap and adds OCR and stronger compression.

The reference product for board-style project work, where dragging a card expresses the state of a task and both an individual and a small team can start quickly. The free tier allows ten collaborators per workspace; paid tiers add calendar, timeline, table and dashboard views.

A cross-platform app that holds tasks and a calendar in the same window, records an item by voice, shares a household shopping list and plans the day. The free tier is meant for personal use over the long run, with builds for phones and desktops.

Polaris Office is a cross-platform office suite the publisher says reaches 234 countries and 130 million users; the web edition needs no install, and the perpetual licence is a one-off purchase that runs offline without signing in.

Evernote keeps notes, tasks and calendar in one place, and version 11 adds an AI assistant, semantic search and meeting transcription; the free tier is capped at 50 notes and a single notebook across five platforms.

Sejda splits its PDF tools into a browser route, where files are processed on the server and deleted afterwards, and a desktop route that works entirely on the machine; the paid tier allows 500 MB per file and up to 21 minutes per task.

Toggl is a time tracking and workload planning tool for teams, with automatic tracking, timesheet reports and invoicing; clients cover Windows, macOS, iOS and Android, and reports break down utilisation and project profitability.

Press enter for a node, drag to change the level, pick a structure and start filling a ready-made skeleton: a mapping tool whose presentation mode saves you from rebuilding the same diagram as slides.

One minute of planning each morning, a clean page for today and tasks that flow in from mail and calendar: a deliberately lightweight task manager that costs nothing and covers Windows, the web and phones.

Monday puts projects on a single colour-coded surface where a table, a kanban board, a Gantt chart and a calendar all read the same data. Drag-and-drop rules replace code, and a small team can start free.

Jira turns requirements and defects into structured issues with a full lifecycle, runs Scrum and Kanban side by side, links commits to tickets and uses natural language to draft new ones. Free for small teams.

Clockify puts the useful parts of time tracking into a free plan with no user cap, then carries the record through reports, approval and a PDF invoice without leaving the same tool.

Standard Notes is an open-source note app with end-to-end encryption that has been running for more than ten years, with a public codebase and independent security audits. The permanently free tier covers encryption, unlimited devices, offline access, tags, per-note passwords, daily encrypted backups and two-step verification, and every note can leave as plain text.

Linear, on the scene since 2019, treats responsiveness as its first principle: the interface answers almost instantly and syncs in the background, so a change made by one person shows up on every screen without a reload. Issues, cycles and roadmaps share one surface, the keyboard covers nearly every action, and the free tier does not cap members.

An open source, self-hosted notebook organised as a tree rather than a flat list. Notes can be cloned into several branches, edited in place with tables, diagrams and formulas, scripted with JavaScript, and reached through a REST API. Run the desktop client or your own server.
