What the directory is, and is not
The AI tools directory helps you choose an outside AI product, such as a chatbot, image generator or coding assistant. It is different from AltFTool's own AI Tools category, which holds AI-powered helpers that run on AltFTool pages.
Every description, feature list and 'best for' line in the directory is written by the AltFTool team in its own words. Rankings are editorial: each tool is scored on how useful it is, how mature it is and how much the free plan gives you. There are no made-up visit counts or star ratings, and placement cannot be bought.
The 16 categories
Tools are grouped by the job they do: AI Chatbots & Assistants, AI Writing, AI Image Generators, AI Photo Editing, AI Video, AI Voice & Audio, AI Music, AI Coding, AI Productivity, AI Search & Research, AI Marketing & SEO, AI Design & UI, AI Logo & Branding, AI Presentations, AI Agents & Automation, and AI for Learning. Each category page ranks the strongest options for that job.
There are also audience lists, such as the best free AI tools and the best AI tools for students, marketers, developers, content creators, small businesses and designers, plus a list of open-source AI tools.
How to pick a tool in five minutes
Start from the job
Open /ai-tools and choose the category that matches what you want to produce, not the tool you have heard of.
Read the top three listings
Each listing says what the tool does, three key features, and who it is best for. Skip anything aimed at a different audience.
Check the pricing badge
Free, Free + Paid, Free trial, Paid or Open source. If budget matters, filter your shortlist to Free or Free + Paid.
Confirm on the official site
Plans and limits change often. Follow the listing to the vendor's site and check the current free-plan limits before relying on them.
Pair AI tools with AltFTool utilities
AI output usually needs a little preparation or clean-up. Draft structured image and video prompts in Prompt Studio, estimate prompt length with the Words to Tokens Estimator, tidy pasted prompts with the Prompt Text Cleaner, and summarise long documents with the Text Summarizer. To automate AI steps end to end, see the n8n workflow templates guide.
