The Nusii Alternative That Writes the Document Instead of Templating It.
Nusii is good if you are happy filling in templates by hand, but it has no AI generation and only makes proposals. The Nusii alternative you want reads your website, drafts a complete branded document from one prompt, and handles far more than proposals, then sends, tracks, signs, and collects payment in one window.

Nusii Templates the Proposal. It Does Not Write It.
Nusii is easy and quick. But teams searching for a Nusii alternative usually want two things it does not do: the document written for them, and documents beyond proposals.
No AI Generation, by Design
Nusii deliberately avoids AI document generation. You build from templates and reusable sections and edit by hand, every time.
Branding Is a Manual Job
You add your logo, fonts, and styling yourself. Nothing is pulled from your website, so each document depends on the person building it.
Proposals, and Little Else
Nusii is a proposal software. For SOWs, decks, reports, one-pagers, or webpages, you are working outside what it is built for.
Templates Still Take Time
Reusable sections speed things up, but you are still assembling and editing each proposal rather than generating it.

Why teams choose Proposal.biz over Nusii
Proposal.biz keeps the speed Nusii is loved for and removes the manual part, generating the document for you and handling far more than proposals.
Smart Content Library: Your Brand, Pulled From Your URL
Nusii asks you to add branding by hand. Proposal.biz reads your website and stores your logo, colours, fonts, services, pricing, and tone as reusable blocks, so every document is on brand from the first line.
The Document, Generated, Not Templated
Nusii gives you templates to fill. Proposal.biz generates the whole branded document from a URL and one prompt, so you start from a finished draft instead of a blank template.
Edit by Chatting, Not Rewriting Sections
Ask Document Chat to rewrite, shorten, or retone any section, instead of editing reusable blocks by hand.
Far More Than Proposals
Generate decks, SOWs, NDAs, retainers, reports, one-pagers, and webpages from the same tool, where Nusii is built for proposals alone.
Engagement Tracking That Times Your Next Move
See opens, scroll depth, and time per section, so you reach out at the moment of peak interest.
Sign and Get Paid Inside the Link
E-signatures and payment collection sit in the shared link on every plan, so clients approve and pay where they read.
The pricing difference
Keep the Simplicity. Add the AI.
Nusii competes on simplicity and a flat, low price, and it earns that reputation. Proposal.biz includes AI document generation and a Smart Content Library on every plan, so you keep the speed and gain the draft. Compare current pricing side by side below.
