AI tools directory: 378 AI tools for work, by category

Updated · By Robert Breen

There are thousands of AI tools, and most teams waste weeks trying the wrong ones. The fastest wins come from matching one tool to one job you already do every week: email replies, meeting notes, proposals, month-end, support questions. This directory lists 378 real, active AI tools in 22 categories, each with what it does for an office worker, whether it is free, and a link to its official site.

How to choose: start with the job that costs you the most time, open its category, and shortlist two or three tools that work with the apps you already use. Check where your client data goes and what the plan costs, then test on a real but low-risk task. Where Stepthrough has a free interactive lesson for a tool, the card links to it, so you can practice before you pay.

LLMs & chat assistants

All 18 AI chat assistants

A chat assistant is the first AI tool most offices pick up, and the one that pays back fastest: a reply that took 20 minutes takes 2, a 40-page contract gets a one-page summary, and a messy export becomes a clean table. The real…

AI agents & agent builders

All 17 AI agent builders

An AI agent does more than answer: it takes a goal, works through the steps and uses your tools to finish the job, such as researching a prospect, onboarding a client or answering policy questions. That is where the big time…

Automation & workflows

All 15 AI automation tools

Email & inbox

All 16 AI email tools

Writing & content

Meetings & notes

All 18 AI meeting note takers

Deals are lost to slow follow-up far more often than to price. AI sales tools keep the pipeline honest: they research accounts, find contact details, draft personal outreach, record calls and remind you who to call next. This…

Marketing & social

Image generation

Presentations & docs

All 15 AI presentation and document tools

Proposals, decks and reports eat whole afternoons of formatting. AI presentation and document tools build a clean first draft from your notes, turn text into diagrams, document a process as you click and let you question long…

Data & spreadsheets

All 16 AI data and spreadsheet tools

Every business runs on spreadsheets, and most people only use a fraction of what they can do. AI data tools write formulas from plain English, clean messy exports, build charts and dashboards and answer questions about your…

Design & UI

Frequently asked questions

How do I pick the right AI tool for a job?
Start with the job, not the tool: write down the task, how often you do it and what it costs you in time. Then pick the category that matches (email, meetings, documents, data and so on), shortlist two or three tools that work with the apps you already use, and test them on a real but low-risk example before you roll one out.
Are these AI tools free?
Many are. Of the 378 tools listed, 236 are free or have a free plan and 85 have a free trial. The pricing badge on each card shows which; plans and limits change often, so check the vendor’s pricing page before you commit.
Is it safe to put client data into an AI tool?
Only when your plan and settings allow it. Check whether the tool trains on your data, where it stores it and whether your business plan turns training off. Business and enterprise plans usually give you more control. When in doubt, remove names and account numbers first.
How often is the directory updated?
New tools are added every day, and the “New this week” box at the top shows the latest. Each tool links to its official site, and where Stepthrough has a free interactive lesson for a tool, the card links to it.
