ChatGPT Prompt for Writing a Business Proposal
Writing a compelling business proposal is a demanding exercise that mobilizes both writing skills, in-depth client knowledge, and strategic structuring of the offer. ChatGPT radically transforms this process by allowing you to produce professional proposals in a fraction of the usual time. Rather than starting from a blank page, you can generate a complete structure tailored to your industry and interlocutor, then refine it as needed. The AI particularly excels at crafting impactful value propositions, logically structuring arguments, and adapting the tone to B2B or B2C contexts. Whether you are a freelancer, corporate salesperson, or SME manager, a well-designed prompt helps you produce documents that inspire trust and facilitate decision-making for your prospects. In this guide, you will find an optimized main prompt as well as variants adapted to your expertise level, to turn ChatGPT into a true sales assistant capable of writing custom proposals that convert.

Frequently Asked Questions
How can I effectively personalize the proposal ChatGPT generates for each client?
The key lies in systematically replacing all bracketed variables with real information specific to your prospect. Go beyond simple fill-in-the-blanks: add references to your previous conversations, incorporate hard numbers from your client discovery process, and tailor case studies to an industry similar to your prospect's. Always read the proposal aloud to ensure the tone sounds natural and authentic, not AI-generated.
What information should I provide to ChatGPT to get the best possible proposal?
The more context you give, the better the result. At a minimum, specify the client's industry, their main problem, and your solution. For an optimal proposal, add: the decision-maker's name and title, estimated budget, competing providers, likely objections, your past results on similar projects, and the desired tone (formal, conversational, technical). Don't hesitate to paste notes from your discovery call directly into the prompt.
Can ChatGPT handle the pricing and financial aspects of the proposal?
ChatGPT can strategically structure the pricing presentation (multiple options, price anchoring, highlighting ROI), but you must always provide your actual rates. The AI excels at crafting pricing justification, calculating a theoretical ROI from your data, and presenting options in a psychologically optimal order. However, never ask it to set your prices: that's a strategic decision that belongs to you and depends on your market positioning.

Gemini Prompt for Summarizing a Document
Summarizing a long document is one of the tasks where Gemini excels thanks to its massive context window, capable of processing up to 1 million tokens. Whether you have a 200-page annual report, a complex legal contract, or a university thesis, Gemini can extract the essentials in seconds. However, a simple "summarize this document" often yields a generic result that misses critical information for your use case. The key lies in a structured prompt that specifies the desired level of detail, the analysis angle, and the output format. A good summary prompt guides Gemini to distinguish essential information from noise, retain important numerical data, and adapt the tone to the target audience. In this guide, you'll find a main optimized prompt along with three variants suited to your expertise level. Whether you're a student looking to synthesize your courses, a professional needing to digest industry reports, or a researcher analyzing scientific literature, these prompts will save you hours of reading while preserving the substance of the original document.
