From RFP to polished first draft, end to end.
PhantomProse is built around a single workflow: turn your best past work into the next proposal you send. Here's exactly how that happens.
Upload writing samples to your library
Add a handful of past proposals, case studies, or service descriptions. The AI studies them to learn your team's voice, sentence rhythm, and structural patterns. It never lifts specific facts, names, or numbers from these documents — they're voice references, not source material. Your library lives in a private workspace — only your team can see it.
- PDF, DOCX, and Markdown supported
- Category-tagged on upload (case study, service, pricing, etc.)
- Used only to shape voice and style, never factual content
Brief the new opportunity in 60 seconds
Paste the RFP or describe the brief. This is the only source of factual content for the draft — every number, name, scope item, and deliverable in the output traces back to what you write here. Pick the proposal type, tone, and (optionally) a budget range.
- Proposal types tuned for SEO, web, paid ads, social, and consulting
- Tone control: formal, friendly, confident, or concise
- Optional budget range and deadline fields
Generate a draft in your team's voice
Every section is drafted from your brief — that's the source of all facts. Your library samples shape how the AI writes (rhythm, vocabulary, structure) without leaking specifics from past deals. The result reads like your team wrote it, but every claim is about this client and this opportunity.
- Section-by-section drafting with structured output
- Brand voice + banned phrases enforced on every section
- In-place editing — no separate review tool
What gets drafted, every time.
A complete proposal has the same skeleton across most agencies. We draft all of it.
Built around how proposal work actually happens.
One library, many proposals
Upload once. Every future proposal pulls from the same approved source of truth.
Automatic case study matching
When the new client looks like a past one, your strongest case study gets surfaced first.
Brand voice respected
Set your voice and banned phrases once. Every draft is consistent with how your team writes.
Citations, not hallucinations
Each section cites the doc it drew from. If you can't verify it, it doesn't ship.
