Glazing & Curtain Wall Estimating
Streamline vs Guthrie AI
Guthrie AI rents you a virtual estimator — an AI assistant and a dedicated human, priced like a hire. Streamline makes the estimator you already have superhuman: 6 hours of bid prep in about 15 minutes, on every bid, starting today.
The honest verdict
Guthrie AI isn't a markup tool — it's a staffing product. $4,125/mo gets you one AI “Virtual Bid Assistant” and one dedicated human “Bid Coordinator” who manage your RFPs, RFIs, and proposals like an outsourced member of your team, and their published numbers back up real results. But it's still headcount: every additional VBA is another $3,150/mo, onboarding runs 2-3 weeks with limited capacity, and your plans and pricing pass through a third party's staff on every bid. Streamline isn't a person you add — it's software your own estimator runs with Bluebeam, the same day you sign up. And it's fast in a way no staffing model is: 6 hours of bid prep in about 15 minutes, a reviewable draft before your coffee gets cold.
Guthrie AI still relies on outsourced staff, not your own team.
Side by side
| Guthrie AI | Streamline | |
|---|---|---|
| Turnaround per bid | Routed through Guthrie's staff and queue — no published per-bid turnaround | About 15 minutes to a reviewable draft, versus 6 hours of manual prep |
| What you're buying | An outsourced AI assistant plus a dedicated human coordinator | Software your own estimator uses |
| Where the work happens | Inside Guthrie's systems, by Guthrie's staff | Inside Bluebeam, by your own team |
| Cost | $4,125/mo for 1 Virtual Bid Assistant + 1 Bid Coordinator | $550/seat/mo through Oct 30, 2026 for GlassBuild bookings |
| Cost to add capacity | +$3,150/mo for each additional Virtual Bid Assistant | +$550/seat/mo, flat, no jump per additional estimator |
| Onboarding | 2-3 week wait, limited capacity | Live on your next bid |
| Trade specialization | Generic commercial bid admin — no glazing or Division 8 focus | Built for glazing — glass types, hardware sets, Division 8 spec |
Where Guthrie AI is genuinely good
Guthrie AI covers more of the bid administration lifecycle than a markup tool does — RFI tracking, compliance monitoring, and proposal generation, not just document extraction. They publish real outcome numbers, and a dedicated human coordinator is a genuine reassurance for a firm that doesn't want to manage AI output alone.
Where it stops
It's an outsourced headcount model, not a tool you own, so it can only move as fast as a person and a queue allow. Every added Virtual Bid Assistant is another $3,150 a month, onboarding takes 2-3 weeks before you're live, and your plans, specs, and pricing pass through a third party's staff and systems on every single bid. Streamline skips the handoff entirely: your estimator has a structured draft in about 15 minutes, not after a coordinator gets to it.
What Streamline does differently
When a plan set and Division 8 spec land, Streamline reads them and pulls out glass types, hardware schedules, basis-of-design products, approved alternates, warranty terms, and required symbols. Then it pre-populates your own bid doc template.
What used to take 6 hours of markup, door schedules, hardware sets, and a draft estimating sheet takes about 15 minutes to get to a structured, reviewable draft. It gets you 80–90% of the way there — not 100%. You still check and finish it.
Can you handle all types of plans?
Mostly, yes. Streamline works across plan and spec formats and gets most bid sets most of the way there. It plugs into Bluebeam, so you finish and verify the last 10–20% where you already work. Nothing about your process has to change.
Who this is for
Built for mid-size glazing contractors running multiple estimators, where bid volume is a real constraint. Not a fit for a one-estimator shop with no backlog, and not built for a six-month enterprise procurement cycle.
Questions estimators ask
- Does Streamline replace Guthrie AI?
- Not necessarily — Guthrie AI covers more of the bid administration lifecycle, like RFI tracking and proposal generation. Streamline focuses on the part that eats the most time up front: reading the plan set and spec and handing your estimator a structured draft in about 15 minutes — superhuman speed, versus roughly 6 hours by hand.
- Is Streamline cheaper than Guthrie AI?
- Guthrie AI's published pricing is $4,125/mo for one Virtual Bid Assistant and one Bid Coordinator, plus $3,150/mo for each additional VBA. Streamline $550/seat/mo if you book during GlassBuild, through October 30, 2026 — cheaper at essentially any team size, and the gap widens as you add seats.
