## The answer, as recorded

Asked on 2026-09-21 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short answer
> 
> For most startups: **Dropbox Sign** if you just need signing, **PandaDoc** if signing is attached to sales proposals, and **SignWell** if you're optimizing for cost.
> 
> Worth flagging up front: this is one of the most SEO-spammed software categories on the web. Nearly every "best of 2026" list I pulled is written by a vendor ranking itself first (Signeasy's list picks Signeasy, PandaDoc's comparison picks PandaDoc, SignWell's "best free tools" picks SignWell). I've weighted those accordingly and leaned on the pricing facts rather than the rankings.
> 
> **1. Dropbox Sign (formerly HelloSign)** - the default I'd pick. Cleanest signing UX in the category, no per-envelope limits, good API if you later need to embed signing in your product. ~$15/mo Essentials for one user; the Standard team plan is $25/user with a 2-seat minimum, so ~$50/mo once you add a teammate.
> 
> **2. SignWell** - best price-to-capability if budget is the constraint. Free tier is 3 docs/month; Light is ~$10/mo for one user with *unlimited* documents and no charge per signer; Business is $30/mo annual. The API is pay-as-you-go after 25 free docs/month, which is a nice on-ramp.
> 
> **3. PandaDoc** - pick this

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.
