I built a tool that generates a Table of Contents from any PDF

This is a really practical idea! Navigating long PDFs without a proper table of contents can be frustrating, so a tool that automatically generates one sounds super helpful. I like that you’re focusing on privacy by not storing uploaded documents, which is important for many users. The MVP approach also makes sense to validate the idea before expanding further. I could definitely see this being useful for students, researchers, and anyone dealing with large reports regularly.

This is interesting. A lot of PDFs are painful to navigate, especially long reports or research papers.

Curious — are you generating the table of contents from headings detected in the document, or using some kind of AI to infer the structure?

Also wondering if it works with scanned PDFs.

This is a great tool, I mean combing through pdfs with huge number of pages is a real pain. Nice one.

For solo operators, a lot of SaaS tools are really just paying for someone else's automation.

The underlying API is often public and cheap. You can string Hunter.io, OpenAI, and a few others together in 50 lines of Python and get 80% of what a $100/month tool does. The cases where SaaS wins: real-time collaboration, complex UX, or teams without Python basics.

But for solo founders doing their own outbound or research, scripts usually win on economics.

Pricing being hard is usually a symptom of not knowing the value precisely enough.

The cleaner framing: what does this save or earn the customer, and what's that worth to them in dollars? If the tool saves 5 hours a week at $50/hour equivalent, that's $1,000/month in value. Charging $49 leaves most of it on the table.

One-time pricing for tools often underprices because the value is ongoing. The model should match how value is delivered.

We are looking for someone who can lend our holding company 300,000 US dollars.

We are looking for an investor who can lend our holding company 300,000 US dollars.

We are looking for an investor who can invest 300,000 US dollars in our holding company.

With the 300,000 US dollars you will lend to our holding company, we will develop a multi-functional device that can both heat and cool, also has a cooking function, and provides more efficient cooling and heating than an air conditioner.

With your investment of 300,000 US dollars in our holding company, we will produce a multi-functional device that will attract a great deal of interest from people.

With the device we're developing, people will be able to heat or cool their rooms more effectively, and thanks to its built-in stove feature, they'll be able to cook whatever they want right where they're sitting.

People generally prefer multi-functional devices. The device we will produce will have 3 functions, which will encourage people to buy even more.

The device we will produce will be able to easily heat and cool an area of ​​45 square meters, and its hob will be able to cook at temperatures up to 900 degrees Celsius.

If you invest in this project, you will also greatly profit.

Additionally, the device we will be making will also have a remote control feature. Thanks to remote control, customers who purchase the device will be able to turn it on and off remotely via the mobile application.

Thanks to the wireless feature of our device, people can turn it on and heat or cool their rooms whenever they want, even when they are not at home.

How will we manufacture the device?

We will have the device manufactured by electronics companies in India, thus reducing labor costs to zero and producing the device more cheaply.

Today, India is a technologically advanced country, and since they produce both inexpensive and robust technological products, we will manufacture in India.

So how will we market our product?

We will produce 2000 units of our product. The production cost, warehousing costs, and taxes for 2000 units will amount to 240,000 US dollars.

We will use the remaining 60,000 US dollars for marketing. By marketing, we will reach a larger audience, which means more sales.

We will sell each of the devices we produce for 3100 US dollars. Because our product is long-lasting and more multifunctional than an air conditioner, people will easily buy it.

Since 2000 units is a small initial quantity, they will all be sold easily. From these 2000 units, we will have earned a total of 6,200,000 US dollars.

By selling our product to electronics retailers and advertising on social media platforms in many countries such as Facebook, Instagram, and YouTube, we will increase our audience. An increased audience means more sales.

Our device will take 2 months to produce, and in those 2 months we will have sold 2000 units. On average, we will have earned 6,200,000 US dollars within 5 months.

So what will your earnings be?

You will lend our holding company 300,000 US dollars and you will receive your money back as 950,000 US dollars on November 27, 2026.

You will invest 300,000 US dollars in our holding company, and on November 27, 2026, I will return your money to you as 950,000 US dollars.

The framing here is useful. The research layer before any outreach is what most people skip because it does not scale well manually. But it is where the ROI actually lives - a tight ICP plus context on each target outperforms volume every time.

Interesting idea.

One thing that might make this especially useful is exporting the generated table of contents as clickable links that jump directly to the relevant sections in the PDF.

A lot of long documents become difficult mainly because navigation is slow, so anything that makes jumping between sections easier could add a lot of value.

Great work!

Clean and useful. The PDF utility space has a lot of tools that over-engineer the problem - this one looks like it solves the specific thing well.

A few niches that pay well for PDF tools: legal teams (contracts), researchers (papers), consultants (reports). The pricing for legal/enterprise use cases is usually much higher than consumer - if you find that your users are mostly professionals, the $0 free tier might be leaving money on the table.

What does the actual user look like for you right now? Are they researchers, business users, students?

Interesting idea. Navigating long PDFs can definitely be painful when there isn’t a clear structure.

One situation where I could see this being very useful is with technical documentation or research reports where the document is 100+ pages and you’re trying to quickly jump to specific sections. Automatically generating a structured TOC could save a lot of time there.

A feature that might make it even more useful would be exporting the generated TOC as clickable bookmarks inside the PDF itself, so the document becomes easier to navigate even outside the tool.

Curious — how well does the system handle documents where headings aren’t perfectly formatted (for example when the structure isn’t consistent)?
