If you draft in AutoCAD all day, cadssistant's appeal is simple. You type a request into a palette inside AutoCAD and it does the work in the open drawing. You don't copy anything out to a separate chat window or paste code back in. Whether it suits you depends on four things: which AutoCAD you run, what leaves your machine, how the message-based plans add up, and what the Revert button does to your work.
cadssistant AutoCAD AI
cadssistant is a palette that sits inside AutoCAD and carries out requests by running AutoCAD commands and AutoLISP. According to the cadssistant product FAQ, it supports AutoCAD 2024 and newer on Windows. AutoCAD LT and AutoCAD for Mac aren't supported. If your office has a mix of full AutoCAD and LT seats, only some of your drafters will be able to use it.
The AI models come with the subscription. On privacy, the vendor says the DWG file itself isn't uploaded, but selected drawing information from your request is sent to the model provider. That's the sentence to pass to whoever handles client confidentiality at your firm. The file stays put, but some drawing content does leave the machine.
How a request runs, and what Revert takes back
You describe the task and cadssistant works through it. It runs commands one after another without stopping to ask for approval at each step. For a drafter, that's much of the appeal: a batch of edits finishes as one piece of work instead of a string of confirmation prompts.
The safety net is Revert. The vendor explains that Revert restores the drawing to where it was at the start of the turn, and that it can also remove manual edits you made after that turn. Suppose you ask for a batch change, then fix a few dimensions by hand while looking over the result, then decide the batch change was wrong. Reverting takes the drawing back to before the request, and your hand fixes can go with it.
The habit to build is to settle the AI change before you work around it. Review the result, revert straight away if it's wrong, and only then carry on drafting. Saving before a larger request gives you a second recovery point that doesn't depend on where the turn began. This matters most in a drawing you've been working in for hours.
What the plans cost
As of November 13, 2026, cadssistant listed two plans, both excluding applicable tax. Pro is €49 a month with 300 messages, and Max is €149 a month with 900 messages. The trial lasts seven days or 30 messages, whichever runs out first. The details are on the cadssistant pricing and usage terms page.
A message doesn't map neatly onto one thing you type. The usage terms limit how many tool steps a message can include, and requests the vendor classes as Heavy count differently from ordinary ones. So a long multistep job may use up the allowance faster than a quick question. That makes the trial the most useful part of the pricing. Thirty messages spent on the kind of work you do every week will tell you more about whether 300 a month is enough than any estimate from the price page.
A good example: renumbering block tags
The vendor publishes a recipe for renumbering block tags, and it's a fair picture of what an in-drawing assistant is good at. Renumbering equipment or door tags by hand after a layout changes is tedious, and a skipped or doubled number is easy to miss. The recipe reports the old and new value for each tag, so you can check the result against your register without hunting around the sheet.
The result is only as good as the rule you give it. Say which direction the numbering should run, such as left to right and then top to bottom. Give the prefix and starting number, and name any blocks nearby that must keep their current values. It also helps to say what should happen when a selected block doesn't have the attribute you're numbering. Usually you want that block skipped and reported, not quietly changed. Our block-attribute automation guide covers how to write those matching and exception rules so the output can be checked against a controlled register.
Jobs like this fit cadssistant well: they're contained in one drawing, repetitive, and quick to verify.
When the job starts outside the drawing
cadssistant's recipes also cover work that starts with an image or PDF, so it isn't limited to information already in the drawing. A different question arises when the same equipment change has to reach a Revit model as well as the DWG. Then application coverage matters as much as the drafting interaction.
ArchiLabs Desktop is an option for that work across both applications. It runs on Windows, works with native Revit and AutoCAD files, and lets you attach the register, the PDFs, marked-up screenshots or the elements you've selected to the same request. Desktop starts at $19 a month plus usage credits (pricing). If your renumbering usually begins with a spreadsheet, try that job in Desktop, from the register through to the finished drawing.
