Proposal writing software for people who care about every sentence
Some proposals win on price. Many win on writing: a summary that shows you understood the client, a scope that leaves no room for doubt and terms that read as fair. ProposalCreation is proposal writing software built around a block editor and an AI writing partner. Draft the whole document from your notes, then rewrite any section in one click until it says exactly what you mean.
How writing a proposal works in the editor
-
Start with a draft
the AI writes every section from your brief, your brand style and your content library.
-
Shape the structure
drag sections, add blocks from the library and remove what this client does not need.
-
Rewrite with AI
select a section and ask for shorter, longer, more formal, more direct or closer to the client's words.
-
Polish together
teammates comment on sections, and version history keeps every earlier draft.
-
Send
export a PDF or send a tracked link with e-signature.
AI section rewrite without losing your voice
The rewrite tool works on one section at a time, so you stay in control of the whole document. Ask the AI to cut an executive summary to half its length, make the terms more formal, add detail to the methodology from your library, or match the wording the client used in the brief. Prices, dates and names are kept exactly as they are. You can compare the rewrite with the original and keep either one.
- Shorter or more detailed
- More formal, more consultative or more direct
- Closer to the client's own language
- Add supporting detail from your content library
Your company voice in every section
Voice notes in your brand style tell the AI how you write: plain or formal, first person plural or third person, short sentences or longer ones, words you use and words you avoid. Upload two or three past proposals and the AI picks up your usual structure and phrasing. Every draft and every rewrite follows that voice, so a proposal written by a new hire reads like one written by your best writer.
A block editor made for proposals
Every section is a block: text, image, pricing table, timeline, team bios, case write-up or signature. Drag blocks to reorder them, duplicate them or save any block to your proposal content library for reuse. Comments sit on the block they refer to, and version history records every change. The editor shows the proposal exactly as the client will see it.
Why writers use proposal writing software instead of a word processor
- The first draft is written for the client, so you edit instead of starting from a blank page.
- Rewrites change one section and leave the rest of the proposal untouched.
- Approved wording lives in the library, so good paragraphs are never lost in old files.
- The finished document goes out as a tracked link with e-signature, not an attachment.
- Your documents stay yours, and we do not train AI models on your proposals.
Which plan fits how much you write
Section rewrites have their own monthly allowance, separate from full drafts.
| Plan | Price billed annually | Seats | AI drafts per month | AI section rewrites per month |
|---|---|---|---|---|
| Starter | $24 per month | 1 | 20 | 100 |
| Growth | $74 per month | 5 | 70 | 300 |
| Business | $149 per month | 15 | 150 | 500 |
| Enterprise | $399 per month | 50 | 400 | 1,500 |
Monthly billing is $49, $149, $299 and $799. Manual editing is unlimited on every plan.
Templates for writing-heavy proposals
Writing-heavy work often starts from the grant proposal template, the consulting proposal template or the marketing proposal template. To see how the first draft is built from your inputs, visit the AI proposal generator.
Frequently asked questions about proposal writing software
Does the AI rewrite change our prices or dates?
No. Rewrites change the wording of the selected section and keep prices, dates, names and figures exactly as they are.
Can I undo an AI rewrite?
Yes. You compare the rewrite with the original before keeping it, and version history lets you restore any earlier version later.
How does the AI learn our writing style?
From the voice notes in your brand style and the past proposals you upload. Every draft and rewrite follows them.
What counts as a section rewrite?
Each AI rewrite of one section counts as one rewrite in your monthly allowance. Editing by hand never counts.
Can teammates review my writing in the app?
Yes. Teammates leave comments on any section, and you resolve them before sending.
