Pros
- + Free SketchUp, Revit, Rhino 8 and Grasshopper plugins render the viewport you model in — in my testing this collapsed export/upload/prompt steps to about a minute per iteration
- + Per-click credit cost is displayed on the button before spending, so I never generated an image without knowing its price first
- + Flow boards compare up to four variations beside the source with full render lineage (source, prompt, engine) recorded for re-runs and branches
- + Broad architectural toolset in one credit balance: exterior/interior/masterplan/landscape, virtual staging, text-guided edits, 8K upscaling and short video clips
- + Free signup credits that do not expire and a no-training guarantee on uploaded data per the pricing page
Cons
- - No BIM intelligence: third-party testing found the Revit add-in captures the viewport but ignores material assignments, flattening Revit to a screenshot
- - Credit costs escalate fast outside basic renders — video runs around 100 credits and Ultra renders triple-digit amounts, which drains a Lite plan (1,000 credits/mo) quickly
- - General batch processing is still roadmap per third-party tests; only Grasshopper offers batching (eight options)
- - Plan structures have changed repeatedly across 2025–2026 and purchases are generally final per third-party summaries of the terms
- - Output fidelity is capped by input quality — loose or messy sketches produce unreliable geometry
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
