AI is showing up on both sides of the submittal. GC platforms now offer agents that check incoming packages against the spec and draft the response to the trade. Other tools check packages one at a time, for either side. Here's how OneRound fits, in plain terms.
| OneRound | GC-side AI agents e.g. Procore Submittal Review Agent, Trunk Tools TrunkSubmittal | Deviation Check | SpecSure | DIY AI chat e.g. ChatGPT, Copilot | AI package builders e.g. Bobyard | Manual review | |
|---|---|---|---|---|---|---|---|
| Who it works for | The submitting side: trade, supplier or rep (GCs can pre-check too) | The GC team running the platform | Subs before submitting, or GC PMs on incoming packages | Both sides: submitters before sending, and reviewers | Anyone with an AI chat account | Any trade preparing submittals (Bobyard's own description) | Whoever has the time |
| When it runs | Before you upload to the GC | When the submittal is in the GC's system. TrunkSubmittal says it "starts working the moment a submittal enters your PMS" | Before you send, or on receipt | Before you send, or on receipt | Whenever you paste or upload | While the package is assembled, after takeoff | Whenever someone gets to it |
| What you get back | Readiness score, 3-step roadmap, compliance matrix, scope gap, finish and prior A/E comment tables | Flagged issues and a drafted response for a person to approve (to the sub, or to the architect) | Deviation report with spec quotes, severity and a suggested fix, with a PM signature line (HTML, Markdown or JSON) | Cited compliance report with a score and flags (PDF or Excel) | A chat answer. Quality depends on your prompt and what you upload | An assembled PDF with cover page and table of contents. You confirm which product and pages go in | A marked-up set and notes |
| Your submittal pages marked up | Yes: numbered clouds that show in the Bluebeam Markups List (Roadmap and up) | Not the trade's deliverable | Not stated on their site | Yes: findings highlighted on the page, numbered to match the report | No Bluebeam markups | The chosen product boxed on each page (not a spec-compliance markup) | Yes, by hand |
| Spec section marked up line by line | Yes (Ready-to-Send) | Not stated | Not stated | Not stated | Only if you prompt for it | Not stated. Bobyard describes matching and packaging product data, not checking it against the spec | Sometimes |
| Cover summary in your name, deviations declared | Yes, with transmittal and ACC / Procore fields (Ready-to-Send) | No, it works for the GC | Not stated | Not stated | Only if you write it | Branded cover page. Declared deviations: not stated | Sometimes |
| Prior A/E comment closeout on a resubmittal | Yes, comment by comment | Not stated | Not stated | Not stated | Only if you prompt for it | Not stated | If someone tracks it |
| Guarantee | Refund or free re-review if the A/E returns it for something we should have caught | Not stated | Their site: "a high-recall first pass, not a defect-free guarantee" | Not stated. Their site: final determinations rest with the engineer of record | No | Not stated | No |
| Price | Free check. $35 / $79 / $149 per submittal, or a 10-report Project pack for $250 | Not public. Sold as part of the platform's AI plans or by quote | $35 per review. Project plan $1,500 per month (80 reviews) | Not public. Free pilot on five submittals | Free or your existing subscription. Data handling depends on your account settings | Not public. Depends on the products and add-ons you use | Your time, plus a full review period for every round |
About DIY AI chat: it's a good free first pass. OneRound adds the full package against the spec, findings pinned to the page, Bluebeam markups, "couldn't check" instead of guesses, and deletion of your files.
