From blank page to ready-to-send in minutes

Answer a few questions about your business and the project. Prosperus writes the proposal. You read it, tweak what needs tweaking, and hit send. That’s the whole process.

AI that knows your business

Tell Prosperus what you do, how you work, and what your services cost. It learns your style once and writes in it every time.

Set your tone

Choose from Professional, Friendly, Casual, Formal, or Enthusiastic. Add custom instructions — “always mention our 10-year track record” or “use British English.” It listens.

Full proposals, not just outlines

The AI generates the project description, deliverables list, phased timeline, pricing packages, and terms. A complete proposal, not a starting point you have to flesh out.

Easy to edit, hard to tell

The output reads like you wrote it. Clients won’t notice. You will — because it took you five minutes instead of two hours.

Services built in

Your service library feeds the AI. It knows what you offer, what it costs, and how long it takes. No re-explaining every time.

Works for any project type

Branding, web design, photography, consulting, dev work. The AI adapts to what the project actually is, not a generic template it’s forcing the content into.

The setup that does all the work

The AI Account Setup wizard is a one-time thing. Tell Prosperus about your business — what you do, your services, your tone, your about section. It populates everything at once.

After that, every proposal you generate pulls from what it already knows. You’re not re-briefing the AI every time. You’re just describing the project.

Where AI ends and you begin

The AI gets you to a complete draft. You review it. You adjust the things that need adjusting — a deliverable that’s off, a price that needs updating, a sentence that doesn’t sound like you.

Most of the time, there’s not much to change. That’s the point.

FAQs

The whole thing — project description, deliverables, timeline, pricing, and terms. You can also use it to generate just your about section, services, or email templates.

Yes. Pick a tone preset and add custom instructions in Settings > AI Style. Changes apply to all future AI-generated content.

No. Your business information stays in your account. It’s used to generate your proposals, not to train any models.

You review before sending. The AI is a drafter, not an autopilot. Read it, fix what’s off, then send.

Yes, on every plan. The AI proposal wizard is available to all Prosperus users.
