Belidor vs Downtobid

Two AI tools that turn a plan set into trade scopes for bidding, aimed at different steps. Belidor is an AI scope-generation tool for GC estimating teams that reads drawings and specs, cites every scope line to its source page, flags drawing-versus-spec conflicts as potential RFIs, and pushes bid packages to BuildingConnected or exports them. Downtobid is bid management software whose AI detects trade packages and drafts scope notes, then sends personalized invitations to bid from the GC's own email and tracks coverage, with a bid board for subs. Desk research from vendor pages read Oct 26, 2026; not tested, no winner.

What it doesScope generation for estimating teams: upload plans and specs to create trade bid packages, with conflicts flagged as potential RFIs. The vendor says drawing-versus-spec conflicts cite both sources, every scope line is cited to its drawing or spec page, packages push to BuildingConnected or export to Excel, PDF or Word, and inputs can be PDF (including scans) or DOCX. Vendor states SOC 2 Type I and II and says documents are processed under terms that exclude training on customer data. Vendor says ~40+ hours of manual scoping per bid becomes about an hour (vendor claim). Re-checked Oct 19, 2026: the FAQ says it works on construction document and design development sets (a schematic set returns thinner scope, with more lines flagged rather than cited), runs in the browser, does not do markup but reads the markups and clouds in a set, and uses large language models with its own engineering around them; during a pilot a Belidor estimator checks how the scope is organized. Sets are encrypted in transit and at rest on US servers and deleted when the project is deleted or on request, and the security report is sent under NDA (vendor statements). Re-checked Oct 20, 2026: homepage and FAQ unchanged in substance (PDF sets including scans and DOCX in; push to BuildingConnected or export to Excel, PDF or Word out; every scope line cited to a drawing or spec page; SOC 2 Type I and II; the FAQ puts processing at under an hour and upload-to-export at two hours or less, vendor statements). Re-checked Oct 22, 2026 (rendered homepage; a plain fetch was rate-limited): unchanged in substance (PDF sets including scans and DOCX in; every scope line cited to a drawing or spec page; drawing-versus-spec conflicts flagged with both sources; push to BuildingConnected or export to Excel, PDF or Word; browser based; a Belidor estimator checks scope organization during a pilot; SOC 2 Type I and II; US servers; no training on customer data). The homepage now adds a customer story and a table contrasting Belidor with generic AI tools. Time-saved, missed-scope cost figures and customer quotes are vendor material and not used. Re-checked Oct 24, 2026 (rendered homepage; a plain fetch was rate-limited): unchanged in substance (PDF sets including scans and DOCX in; every scope line cited; drawing-versus-spec conflicts flagged with both sources; push to BuildingConnected or export to Excel, PDF or Word; browser based; a Belidor estimator checks scope organization during a pilot; SOC 2 Type I and II; US servers; no training on customer data; documents deleted when the project is deleted or on request). The homepage adds a second customer story; customer quotes and figures are not used.

Customer quotes and time or cost figures are vendor material and not used.Bid management software where AI reads uploaded plan sets, detects trade packages, and drafts scope notes for GCs' invitations to bid. GCs send personalized ITBs from their own email and track coverage. Subs get a bid board for invites, deadlines, and RFIs. Dodge Construction Network now lists "Bid Board by Downtobid" as part of the Dodge family; Downtobid's own site still sells it. Re-read Oct 17, 2026 (rendered in headless Chrome; curl gets a bot check): the homepage says nothing goes out without the GC's review, invites carry each sub's scope summary, relevant sheets and the GC's branding, and sub lists import by CSV with matching to Downtobid's database and duplicate flags; a case study cites 15 minutes vs 2+ hours to build packages and 3.8 vs 1.9 bids per package (vendor case study, not verified). Re-checked Oct 19, 2026: (headless Chrome) unchanged in substance; the FAQ now describes transparent per-user pricing versus revenue-percentage pricing even though its price answer quotes a per-organization starting price, so confirm the billing unit. A GH Pastor case study cites 15+ hours saved per week (vendor case study, not verified). Dodge's Bid Board page still sells Bid Board by Downtobid. Re-checked Oct 20, 2026 (headless Chrome): unchanged in substance; the FAQ still pairs a per-organization starting price with a line about transparent per-user pricing, so confirm the billing unit. The homepage also links comparison pages against BuildingConnected, SmartBid, ConstructConnect, PlanHub, Pantera Tools, Procore and BidMail (vendor framing). The MRI Builders quote and GH Pastor case-study figures are vendor material not used as findings. Re-checked Oct 21, 2026 (headless Chrome; curl got a rate-limit response): homepage unchanged in substance; it now presents Downtobid as an alternative to BuildingConnected, iSqFt, PlanHub and SmartBid (vendor framing), and the sub-side copy lists getting on more bid lists, one deadline calendar and estimator assignment to stop double-bidding. downtobid.com/pricing returns a not-found page; prices are still only in the FAQ. Re-checked Oct 22, 2026: unchanged in substance; the homepage compare links are BuildingConnected, Smartbid, ConstructConnect, PlanHub, Pantera Tools and Procore. downtobid.com/pricing was rate-limited today (HTTP 429), so prices were read from the FAQ. Re-checked Oct 23, 2026 (homepage rendered in a headless browser after the plain fetch was rate-limited): unchanged in substance (AI bid invites from plans, sub matching by scope, bid tracking); the footer again lists seven vendor comparison pages, including one against BidMail. Re-checked Oct 24, 2026 (read through a text fetch after the plain request was rate-limited, HTTP 429): homepage unchanged in substance (AI package detection from plan sets with scope notes, personalized ITBs from your own email, coverage tracking, sub bid board, CSV sub-list import). Customer quotes and the time-to-packages and bids-per-package case-study figures are vendor material not used here. Re-checked Oct 25, 2026 (homepage rendered in a headless browser; plain requests were rate-limited): unchanged in substance (AI that reads bid invites and plans, finds subs and sends invites for GCs, plus the bid board for subcontractors). The homepage strip naming it an alternative to other bid platforms is not used here. Re-read Oct 26, 2026 for a compare (headless Chrome): homepage unchanged in substance (AI reads every sheet, identifies trade packages and drafts scope notes; nothing goes out without the GC's approval; personalized ITBs from the GC's own email with each sub's scope summary and sheets; sub bid board with deadlines, RFIs and estimator assignment). Customer quotes and case-study figures are vendor material not used.

Where the vendor descriptions differ

  • Who it is for: Belidor pitches general contractor estimators writing detailed scopes of work for bid packages. Downtobid pitches GCs sending invitations to bid and subcontractors managing invites, deadlines and RFIs.
  • Scope output: Belidor says it reads drawings, markups and specs, cites each scope line to a drawing or spec page, and flags conflicts and alternates with both sources; it works best on construction document and design development sets. Downtobid says its AI reads every sheet, identifies trade packages and drafts initial scope notes for each invite.
  • Review: Belidor says an estimator reviews and edits the scope, and during a pilot a Belidor estimator checks how scopes are organized. Downtobid says you review and edit before sending and nothing goes out without approval.
  • Where it goes next: Belidor pushes bid packages to BuildingConnected or exports Excel, PDF or Word, so it sits upstream of an ITB tool. Downtobid is itself the ITB tool: personalized invites with each sub's scope summary, relevant sheets and the GC's branding, coverage tracking, and sub list import by CSV.
  • Security: Belidor states SOC 2 Type I and II, US servers, no training on customer data and deletion on request (vendor statements). Downtobid's homepage does not state security certifications in the text we read.
  • Pricing (checked Oct 26, 2026): Belidor lists no prices; plans are priced per organization with no limit on projects or document size, covered on a demo call. Downtobid's FAQ lists $149 a month for your organization for GCs, $119 a month for the sub leads bid board and $299 a month for full sub bid management, and says subs bid free.
  • Not like-for-like: a GC that wants cited, conflict-checked scope writing would look at Belidor and keep its ITB platform; a GC that wants AI-drafted scopes inside the invite and coverage workflow would look at Downtobid. Some teams could use both.
  • Not used here: Belidor's time-saved and missed-scope cost figures and both vendors' customer quotes and case-study numbers (vendor content).
