Quilter
Pros
- + Per-project billing counts only unrouted pins at upload — in my test a pre-routed power section correctly reduced the design pin count, letting engineers hand off tedious routing while keeping critical RF/power work themselves
- + Unlimited free iterations per project (within 10% BOM change) plus parallel jobs meant comparing a 4-layer and 6-layer variant of one board overnight at no extra cost
- + Outputs land in native Altium, Cadence Allegro, Siemens Xpedition or KiCad formats — no proprietary lock-in, and files opened cleanly for DRC and fab prep
- + The two-to-five-cycle expectation and the circuit comprehension report are honest about where human review stays mandatory, versus one-shot-layout marketing elsewhere in this category
- + Deployment flexibility with a managed AWS cloud (SOC 2 Type 2, isolated workspaces) or self-hosted option where board data never leaves your infrastructure
Cons
- - No public per-board prices — cost is a sales conversation despite the transparent pin-count model, so budgeting is opaque before first contact
- - Free-tier designs may be made public, which excludes confidential work from the zero-cost path
- - A BOM change beyond 10% of the upload starts a new billable project, which penalises respun designs
- - Automated layout is not design validation: DRC-clean candidates still need thermal, EMC and DFM review, and the vendor's own guidance expects 2–5 iteration cycles
- - Supports four ECAD tools for output; teams on Eagle, Proteus or browser-based suites face import friction, and the company is young enough that its long-term track record is still being built
GPT for Sheets and Docs
Pros
- + Cell-level functions (GPT, GPT_TRANSLATE, GPT_EXTRACT, GPT_CLASSIFY) process thousands of rows independently, and in my 500-row test a deliberately exhausted credit balance reported the run as interrupted while preserving per-row success/failure counts
- + Pay-as-you-go to subscription economics with $25/month Standard including $25 of usage and shared extra-usage pools on Business at $45/seat — no per-seat AI lock-in for spiky agency workloads
- + Enterprise plumbing is real: ISO 27001 certification, SAML SSO on Enterprise, BYOK/custom endpoints, zero-data-retention options and a stated no-training policy (vendor documentation)
- + Model breadth across OpenAI, Anthropic, Google and others, with Autosheet MCP (shipped August 2026) letting Claude or ChatGPT drive the spreadsheet agent from an external client
- + Detailed usage reporting maps credit spend to tokens and requests, so I could price each bulk column before committing to a run
Cons
- - No permanent free tier: the trial credits run on a single model, so the multi-model selling point cannot be evaluated without subscribing ($25/month at time of writing)
- - Docs usage billing is not explained on the pricing page, which covers Sheets and Excel plans only
- - The mid-2026 rebrand to Autosheet means listing names, website and docs disagree for now — a mild tracking burden for buyers
- - Multi-account Google sign-ins trigger documented authorization errors; Workspace admins must allow add-on execution
- - The sidebar agent writes formulas but does not reason about cross-sheet business logic — tasks execute, outcomes are still yours to verify
