This is the legal AI stack employers expect you to know. Organized by what each tool replaces, with pricing and the use case that matters most.
The Stack
This is the legal AI tool stack we see in real job postings and practitioner workflows. We organized it by category so you can see what each layer does, then picked the leaders in each. Pricing reflects publicly listed plans as of 2026.
Don't try to learn all of these. Pick one tool per category, get usefully fluent, then add adjacent tools as your work demands them. The skills you build with one platform mostly transfer.

How To Choose
If you're an individual contributor learning on your own time: start with the cheapest or free tier in each category. ChatGPT, a tool with a generous free plan, and one specialized tool. Total spend stays under $50 a month.
If you're picking tools for your team: weigh integration first, capability second. The best tool that doesn't connect to your data is worth less than a B+ tool that lives where your work happens.
Once you've picked, read the matching skills page for what to learn first, or the 6-week curriculum for the sequenced plan.
Common Questions
There isn't one. The right answer depends on your existing stack, budget, and what you're trying to automate. Most legal pros end up running 2-3 AI tools, not one. Use the categories above to pick one tool per layer.
An individual can stay under $50/month using ChatGPT plus one specialized tool. A team usually lands at $50-150 per seat per month for the full stack. Heavy users at AI-forward companies can hit $300+ per seat.
Some are. Spreadsheets are losing share to AI-assisted analysis. Standalone copywriting tools are losing share to ChatGPT. The pattern is consolidation toward AI-native platforms that absorb adjacent functions.
No. The skills you build with one tool transfer to its replacement. Prompt design, workflow building, and eval thinking are platform-agnostic. The cost of waiting is higher than the cost of switching.
Yes. Pick the AI tool that maps to your most repetitive task. Run it in parallel with your normal workflow for a week. The compounding starts immediately.
