The best Revit tagging plugins for MEP in 2026

We make RayCAD, so it comes first on this list. We've kept the rest accurate, with every fact sourced and dated, so you can check our work.

Most tools on this list work fine when a view has a few elements and a few tags. They put a tag at the centre of an element, at an offset you pick, or at the start, middle or end of each segment. A production MEP sheet is a different job. Ducts and pipes run side by side, many elements need 5 or 6 tags, and every tag has to sit close to its host without crossing anything. That's where we tested each tool.

The list at a glance

RayCAD is the only tool on this list that spends the trial with you. We onboard your whole team, set RayCAD up to your tagging standard and run it with you on your own live sheets, so by day 15 you've seen what it saves on real projects. If you didn't get to use it properly, we extend the trial, and we talk price only after you've seen the savings. Everywhere else, you install the plugin and work it out alone.

1. RayCAD

RayCAD is a Revit plugin built for one job, tagging MEP production and shop drawings. It's the tool we make.

• Neat on dense sheets. Tags sit close to the element they describe, go inside it when they fit, and get a leader only when they need one. Leaders join the tag square, never cross another tag, and only bend outward. Many elements on a shop drawing need 5 or 6 tags, and RayCAD packs them the way an experienced drafter would.
• Tags where the information changes. Size, elevation and direction changes, plus long runs that need a tag to stay readable.
• Never an empty or "?" tag. Every tag is checked before placement. The bad ones go to the review panel with the reason.
• Seconds per view. A section takes under 5 seconds, the biggest floor plans a minute or two.
• Your data stays on your machine. We send usage telemetry only, and you can switch it off. We sign an NDA.
• Configured to your standard, and changed for your firm if the options don't cover it, with the founders on WhatsApp or Microsoft Teams.
• Trades: HVAC and piping today, native and fabrication. Electrical and fire sprinklers ship next week.
• Revit 2021 to 2027.
• Price: $200 a month for the whole company, every user licensed. The 15-day trial is free, with onboarding for the whole team.

Orbit Engineering Services reports around 70% less tagging time with RayCAD compared with its previous manual workflow.

2. Bimrock Autotag

Bimrock Autotag places tags from rule-based profiles and sells "overlap-free tag placement". On a production HVAC plan in September 2026, it fanned hundreds of tags out on long leaders from a few points, left dozens of "?" tags, and took 15 to 20 minutes per view. Its public demos are sparse views. It sends "stripped-down placement information" to Google Cloud and keeps it for up to 60 days. Bimrock's home page now leads with "Automate MEP Design & Engineering". Revit 2023 to 2027. Full comparison.

3. BIMLOGIQ Smart Annotation

Smart Annotation places tags from templates and sells "zero overlaps guaranteed". On our September 2026 run it scattered tags far from their hosts with long diagonal leaders, left "?" tags, and took 15 to 20 minutes per view. Its own tutorial says data is "sent to the servers". BIMLOGIQ now leads with Argus, its chatbot, and Smart Annotation's last Autodesk App Store update was in July 2025. Revit 2022 to 2026. Smart Annotation PRO is listed at $2,240 a year per user, and its 14-day trial is self-serve. Full comparison.

4. Tagitize

Tagitize runs a Tag All across several views at once with overlap avoidance, grouping, conditional tags and a tag audit. It's a simple tool for a few elements and a few tags, closer to a public script than a production tagger. $25 to $30 a month for one user, $50 to $75 floating.

5. Revit Tag All

The command built into Revit. It tags every untagged element at the same default spot, with no overlap handling, and you clean up after it. RayCAD vs Tag All.

6. Dynamo and pyRevit

You can script tagging yourself. Placement and overlap logic are the hard part, and the script breaks on the next view you didn't write it for. See build vs buy.

7. Documentation and MEP suites

Tagging is a side feature in these, with fixed positions and no placement logic.

• Chaos Glyph (EvolveLAB) tags by category with orientation and leader settings, next to views, sheets and dimensions. $97 a month named.
• MLABS MEP Automation Suite tags untagged elements and aligns tags, among dozens of routing and modelling features. $16.65 a year.
• Naviate MEP (Symetri) is a modelling suite. "Tagging complex lighting plans" is its only tagging mention. €1,020 a year.
• GRAITEC PowerPack Pipes Description tags ducts and pipes at a fixed distance or a fixed point (start, middle or end of each segment), "the same for all selected elements".

8. Ideate Annotate

Ideate finds annotation clashes and blank or "?" tags after they're on the sheet. It doesn't place tags. RayCAD stops them reaching the sheet.

9. Click-savers

These make manual tagging faster. You still place every tag.

• Bird Tools Tag Alignment and Tag Stacker align tags you've already placed into columns and stack identical ones. $10 a year per seat, $299 a year for a team. Revit 2017 to 2027.
• Tag Master places each tag at a set offset as you click, with align, leader angle and elbow tools. It needs edits to your tag families. Free since April 2026. Revit 2023 to 2026.

10. AI agents

Prompting doesn't solve tagging. These agents look at the sheet, place a few tags, look again and think on every turn, so a full view is painfully slow. You have to tell them when to tag, when not to, and which families to use.

• BIMLOGIQ Argus is BIMLOGIQ's Revit chatbot, where tagging is one prompt among many.
• ArchiLabs tags as one task among modelling and sheets, and now describes itself as "built for data centers". $19 a month plus usage credits.
• Nonica Revit MCP lets Claude or ChatGPT call create_tags_on_view with an offset and a leader. There's no placement logic; the chatbot guesses.
• AutoMEP runs in the browser. You upload your whole RVT, type "tag every duct segment on level 3", and download the file back. Your entire model leaves your office.

Purpose-built software tags a view in seconds because it already knows how a drafter tags. RayCAD is a mix of deterministic rules and machine learning that knows how a drafter tags.

How to choose

Pick RayCAD. A sparse plan with a handful of tags or a packed shop drawing with thousands, RayCAD tags it neatly in seconds, never places a bad tag and keeps your drawing in your office. Every drafter in your firm gets a license for one flat price, and the founders are a message away when you need a change. Try it for 15 days on your own live sheets, and we'll set it up with you.
