## The answer, as recorded

Asked on 2026-09-24 through Claude (Anthropic) with web search (model claude-opus-5).

> ## What I'd actually pick
> 
> **1. Dropbox Sign (formerly HelloSign) - my default recommendation for most startups.**
> Cleanest signing UX of the mainstream options, and critically, API access is on the mid-tier plan rather than gated behind an enterprise contract. If there's any chance you'll want to embed signing into your own product (onboarding flows, contractor agreements, customer paperwork), this is the one that won't force a sales call later. Essentials runs ~$15-20/mo. ([Dropbox Sign pricing comparison](https://www.stackscored.com/pricing/e-signature/), [API tier notes](https://www.turbodocx.com/best-esignature-api-comparison))
> 
> **2. SignWell - best value if you just need signatures and nothing else.**
> Free plan covers 3 documents/month with audit trail and tamper-evident sealing; paid starts at $10/mo per sender. The API is genuinely startup-priced: first 25 docs/month free, then ~$0.85/doc sliding down with volume - no contract, no "contact sales." For a seed-stage company signing a handful of NDAs and offer letters, this is the lowest-friction, lowest-cost real option.

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
