Hi HN,

We’re building DataRiver, a tool that converts PDF bank statements into structured, Excel-ready data (transactions, balances, dates), with a strong emphasis on privacy.

Unlike generic PDF extractors, DataRiver runs on a privately developed AI model trained specifically on bank statement layouts. Uploaded files are processed by our own model and are not sent to third-party LLM APIs, nor reused for training.

This approach came from working with sensitive financial data where accuracy and data isolation matter more than general-purpose flexibility. Many real-world statements include inconsistent tables, wrapped descriptions, or mixed formats that break rule-based tools.

Key points:

Private, domain-specific model for financial statements

High accuracy on messy, multi-column PDFs

No reuse of customer data for training

Files processed transiently and not stored long-term

DataRiver is used by accountants, auditors, and founders who need clean data without risking data exposure.

We’d appreciate feedback from anyone dealing with financial PDFs, especially on edge cases, privacy expectations, or compliance requirements.

Happy to answer questions.

lol that is funny

the bookmark management is very cool.

What use cases do you have in mind?

that is a cool list.

I love Todoist, but pen&paper to-do lists work better.

Qigong and weight-lifting is a life-changing routine for my focus.

Do you drink coffee? Stay away from Robusta and add Matcha to your routine.

That is a cool video. Is your editor available for hire?

It depends.

If you need to ask this question, then ship small to your audience first.

trading needs a high degree of trust. You could convert more people by a few simple changes to the text and color.

Do not get stuck in the game of words.

UI Component Names can be quite fluid.

Shopify Polaris Design System calls them "feedback indicators"

Carbon by IBM calls them notification https://carbondesignsystem.com/components/notification/usage...

You should read these two guides.

And try to find a common ground with your team.

Type size would convey hierarchy much better than most graphic decoration.

If you want to dive into how to design for glance. Recommend Stephen Few's books.

I also would add your name and your Twitter handle. It builds trust and bring opportunities.

Hey this is a cool idea. I love minimalism apps.

Comic Sans is too distracting though. Try DM Sans, Inter, Work Sans for the minimalism feel.

hi cool ideas.

As a foodie, I salute the idea.

A few easy points to improve the design (and the conversion)

- Do not use the current pairing of yellow and green. It reminds me of radioactive colors. Not good for food - Use a serif from Google Fonts to bring a premium feel, try Crimson or Merriweather for example - Some of your gradients contain dead zone, search for clean gradient generation tool. This one https://www.learnui.design/tools/gradient-generator.html

- Avoid white text on white. Even with the drop shadow, it doesnt work. Check for WGSA contrast color tools if you are stuck.

Overall, good job for launching. Good luck.

they need to cut down work hours

look at the story of Evan Spiegel, Snapchat. Also his mentor, Scott Cook.

that is so cool. Care to share a clickable link?

I have been thinking about building a privacy-first tracking app for years now.

Hey, this is a super common problem founders face.

And you will encounter them again again even during your GTM phase.

The team at Wiz (acquired by Google for USD 32 billion) has the perfect strategy to overcome the sugar-coated feedback when pitching. They called it the "false positive"

I covered it here https://www.sandrasletter.com/p/the-design-strategy-behind-t...

Having more karts is an interesting marketing point. But more choices can overwhelm users.

Nintendo should have used Progressive Disclosure Design to reveal new karts as the game progresses.

Also, it could drive user interest when they can unlock secret mode, secret items from hidden mechanics inside the game.

interesting report. I would love an update on the Chinese sentiments in 6 months from now.

a superior tip that works for me:

- give the first draft an extremely low bar

This relieves the pressure, stops my procrastination.

Once you have the first draft, you will get into the flow easily.

Start when you can.

readCV got substantial tractions before shutting down. You should look into it.

this is such a cool piece of history, make me want to write a similar guide about coffee.

thanks for sharing, Pete

I think some startups raised money with similar ideas before?

cool, plan to build something?

that is super fast. Did you Cursor this?

as a history nerd, this is very neat.Thanks for the link

hey, not an engineer but this could happen to any teams.

If you are doing this two things, you should do well.

1. Take care of yourself first. It is easier to act the right way and manage any situation when you are mentally and physically fit.

2. Take a step back and count your breath before reacting. Always assume the other person is hungry, stressed, have family issues, anything. Do not take any thing personally. Give yourself space and address this later.

Also show an effort in your questioning that you research well and could not find the anwser.

It is a great thing for the market and the consumers. Complacency is a great disease of a design team.
