AutoCAD AI in 2026: what Autodesk built in and what you can add

Autodesk's own AI speeds up blocks, markups and questions. None of it drafts geometry for you, which is the gap the add-ons further down fill.

• Smart Blocks (AutoCAD 2024 and 2025): Placement suggests where a block goes from where you put the last ones; Replacement and Search and Convert find geometry that repeats and turn it into block references.
• Markup Import and Markup Assist (AutoCAD 2023 and newer): a photo or PDF of a marked-up print is laid over the drawing and the handwritten notes are read as text you can place or act on.
• Activity Insights and My Insights: Macro Advisor: a record of what happened in the drawing and who did it, and suggested command macros for the sequences you repeat.
• Autodesk Assistant: a chat panel that answers how-to questions about AutoCAD, included with the subscription. In AutoCAD 2027 a tech preview lets it answer about the current drawing, select objects from a text prompt and compare the drawing with a CAD standards file; AutoCAD 2027.1 (August 2026) extended it.

• Built in: Autodesk Assistant, described above. Answers and, in 2027, drawing-aware queries, selection and standards checks.
• An AI palette inside AutoCAD: cadssistant, Cizgen, AEC Pilot, Muhandis. You type in a panel docked beside the drawing and the assistant works in the drawing itself.
• A connector for a desktop AI app: HuskyBIM, AEC Pilot's MCP bridge, open-source MCP servers. Claude Desktop (or another MCP client) gets tools that reach into your AutoCAD. You bring the AI subscription and do the setup.
• A chatbot that writes code: ChatGPT, Claude or Gemini in a browser write AutoLISP or a script, and you load and run it. Free, but the chatbot never sees your drawing. See Can ChatGPT control AutoCAD?.

A plugin is anything that loads into AutoCAD: a .NET add-in, an AutoLISP routine or a palette. The AI add-ins in the table are one of those, installed like any other AutoCAD app, from the vendor's installer or the Autodesk App Store.

cadssistant installs as an AutoCAD plug-in bundle and opens with the CADSSISTANT command as a palette docked beside the drawing. There is nothing to configure: no API key and no model to choose; the free trial starts with the account.

What to look for in an AI plugin: that it works on the drawing you have open, that it asks you in the drawing when it needs a point or an object instead of guessing, and that you can take back what it did.

An agent is an AI that works in steps: it reads the drawing, decides what to do, does it, checks the result and carries on until the task is done or it needs you. The AI palettes in the table are agents inside AutoCAD; cadssistant works that way, reading geometry, layers and blocks back after each change to check what it drew.

MCP (Model Context Protocol) is how a desktop AI app such as Claude Desktop or ChatGPT gets tools that reach into AutoCAD on your PC. Connectors such as HuskyBIM, AEC Pilot's bridge and the open-source autocad-mcp take that route: you bring the AI subscription, install the server, and the AI app drives AutoCAD from outside it. See Can ChatGPT control AutoCAD? and automating drafting with AI.

Searches for an AutoCAD AI generator usually mean one of two things. Image generators make a picture of a plan, not a DWG: nothing you can dimension or edit. A drafting AI makes real entities, lines, polylines, blocks and text, in layers, in your drawing.

From a brief, cadssistant draws a schematic plan: walls as polylines, repeated furniture as a block placed in a grid, labels on an annotation layer, with the scale and origin stated first. From a screenshot or PDF it redraws the plan the same way, as a redraw rather than a trace, and tells you what it estimated so you can measure one wall to check the scale. See a floor plan from a description and from an image.

Expect a starting point in the right layers and at the right scale, not a permit set.

• Autodesk Assistant is included with an AutoCAD subscription.
• ChatGPT, Claude or Gemini in a browser write AutoLISP for free; you load and debug it, and they never see the drawing. See AutoLISP with AI.
• autocad-mcp is open source (MIT) and free; it needs Claude Desktop or Claude Code and some setup. HuskyBIM's connector is free with an account and uses your Claude plan.
• cadssistant has a 7-day / 30-message free trial, no card required.

cadssistant opens with the CADSSISTANT command as a palette docked beside your drawing. You say what you need, for example "dimension the north wall" or "put a 600 mm grid of circles inside this boundary". When it needs input it asks through AutoCAD's own prompts: you pick the point, the corner or the objects in the drawing, and Esc cancels like any command.

It runs AutoCAD commands and AutoLISP directly, creates many entities in one step, and reads geometry, layers and blocks back so it checks what it drew. You can attach a screenshot or a PDF of a plan.

It works in AutoCAD 2024 and newer, including the industry toolsets, on Windows. The AI models are included, so there is no API key and no separate Claude or ChatGPT subscription. You choose an effort mode (Standard or Heavy), not a model.

For the exact sentences and what happens in the drawing, see the recipes: counting and measuring, bulk edits, grids and patterns, Excel exports, AutoLISP.

• You only want answers about commands and settings: Autodesk Assistant is already in your AutoCAD at no extra cost.
• You want the AI to draft and edit in the drawing, without setting up API keys: an in-drawing palette such as cadssistant.
• You use AutoCAD LT: the open-source autocad-mcp with Claude Desktop, or AutoLISP written by a chatbot. See AI for AutoCAD LT.
• You already pay for Claude and live in Claude Desktop: a connector such as HuskyBIM.
• You want to pay with your own API account or run a local model: Muhandis or AEC Pilot.
