Humanize AI
Business Proposal — sound like you wrote it.

Cool the consultancy-deck rhythm — the ‘executive summary’ scaffolding, the ‘proven methodology’ buzzwords, the deliverable-list closer. Penshift's humaniser rewrites AI-drafted business proposals into prose that reads like you wrote it — sentence-rhythm variation, plain vocabulary, broken templates. Free tier, 5,000 words a month, no card needed.

Why this matters for business proposals

AI business proposals have a fingerprint.
Reviewers know it.

Procurement teams and clients have grown allergic to AI-drafted business proposals. The ‘executive summary’ that summarises nothing, the ‘proven methodology’ section that explains no actual method, and the parallel deliverable list — they now actively reduce close rates. Penshift’s humaniser rewrites proposals into prose that reads like a person who has actually done the work wrote it.

  • 03‘Leveraging’ / ‘facilitating’ / ‘enabling’ as default verbs
  • 04Three-pillar value proposition framing
  • 05Deliverable lists with parallel grammar but vague content

FAQ — humanising business proposals

Questions people ask about humanising business proposals.

Will the humanised proposal still look professional?+
Yes — and it’ll close better. Procurement teams trust specific, concrete proposals over consultancy-template language. The phrase ‘we audit your existing analytics stack’ outperforms ‘leverage industry-leading expertise’ on every measurable outcome.
Should I keep the executive summary?+
Yes — but make it actually summarise. Penshift rewrites generic executive summaries into ones that contain the actual scope, timeline, and price up front.
Does it work for RFP responses?+
Yes — and humanising RFP responses typically lifts win rates because most respondents use the same AI templates, so a humanised response stands out in the review pile.
