To streamline this, I fed DeepSeek all my sales and performance data and gave it the following prompt:

"Pull the latest sales and performance data from my CRM and spreadsheets. Organize the information into a structured report and either email it to my team or save it in a shared folder".

DeepSeek executed this flawlessly. It automatically retrieved the latest figures from my CRM, cross-referenced them with spreadsheet data, and compiled a well-structured report—without requiring any manual intervention. It correctly identifies key performance metrics, ensures consistency in formatting, and minimizes errors that often occur in manual reporting. The automation has allowed me to focus on analyzing the data rather than spending time gathering it.

2. Marketing: Creating Content with AI

• Writing Social Media Content Automatically

I recently needed to plan an entire week of LinkedIn content but wasn’t sure where to start. I provided DeepSeek with a few topic ideas—like Best Productivity Hacks and How to Stay Motivated at Work, instead of spending hours brainstorming I decided to experiment with DeepSeek.

I gave it the following prompt:

"Generate multiple engaging social media captions and relevant hashtags based on the topic provided. Format them in a way that suits LinkedIn, Instagram, and Twitter".

DeepSeek didn’t just generate generic captions—it tailored them based on tone, audience, and platform requirements. The hashtag suggestions were relevant and aligned with current trends, improving post visibility.

• Creating Google & Facebook Ads Quickly

I needed to create an ad copy for an AI software product. Instead of manually drafting multiple versions, I uploaded a list of campaign-related keywords, such as AI tools for business and smart automation for companies, so I could get ad copies for different audiences, tweaking headlines, and optimizing call-to-action phrases required hours of effort. To streamline the process, I decided to put DeepSeek to the test.

I gave it the following prompt:

"Generate multiple ad variations, including headlines, descriptions, and compelling CTAs, based on the provided keywords and target audience. Ensure the copies are optimized for Google Ads and Facebook Ads".

DeepSeek quickly processed my input and generated multiple ad variations tailored for different audience segments. The AI ensured that each version had a unique hook while maintaining a persuasive and action-driven tone. It created persuasive, targeted variations that were structured for maximum engagement. The copy was optimized for digital advertising platforms, ensuring clarity, relevance, and strong call-to-action messaging.

I was able to review the copies, make slight modifications, and upload them directly to Google Ads and Facebook Ads Manager without spending hours crafting individual versions.

• Testing It with a Calculus Problem

Mathematics has never been my strong suit, and solving complex equations manually often takes longer than expected. To put DeepSeek’s problem-solving abilities to the test, I experimented with it by feeding it various algebraic and calculus-based problems.

I gave it the following prompt:

"Solve the following mathematical problems step by step. Provide detailed explanations for each step to ensure clarity".

DeepSeek efficiently processed each equation and provided clear, structured solutions. It didn’t just spit out an answer—it broke down every step, explaining the logic behind each calculation.

Example: Testing It with a Calculus Problem

I inputted a calculus problem involving differentiation:

Find the derivative of f(x) = 3x² + 5x - 7.

DeepSeek quickly responded with:

Apply the power rule: d/dx [x^n] = n * x^(n-1).

Differentiate each term separately:

d/dx [3x²] = 6x

d/dx [5x] = 5

d/dx [-7] = 0

Final result: f'(x) = 6x + 5.

The AI explained each step logically, making it easy to follow. Whether solving equations, finding integrals, or tackling probability problems, DeepSeek proved to be highly accurate and efficient.

DeepSeek performed exceptionally well in mathematical problem-solving. It didn’t just provide an answer—it ensured that each step was clear and properly structured.
