Hello HN, I’m a solo developer building tools for real estate workflows. I built OfferGridAI after watching listing agents repeatedly struggle with the same problem during hot markets. When a property gets multiple offers, each offer usually comes in as a 10–20 page PDF. Under tight time pressure, agents have to manually dig through each document and rebuild a spreadsheet to compare things like price, net to seller,…

> each offer usually comes in as a 10–20 page PDF. When sold out vacation home, we had multiple offers, but I seem to recall the offer letters being 1 pagers. Does offer letter length vary by region?

I just built this yesterday, so 0. Want to be my first?

I assume this means the reviews under "Trusted by Listing Agents" are AI generated as well?

Tangential question: I've never owned a home and would like to try to buy one in the next year or two. There doesn't seem to be much in the way of API's/software tools that let you analyze historical data and prices of listings in specific areas. How can I get my hands on the right information to make sure I don't get ripped off?

For covering the risk of mistakes I suggest considering ways of "visually quoting" the documents. If the summary says "closing timeline: X" but there's an icon I can click that pops open an overlay with a visual cropped screenshot of that part of the original PDF - maybe even with a red circle around that detail - I can trust those summaries a whole lot more. Gemini 2.5 has image bounding box and masking features tha…

Oh I didn’t know about the visual bounding boxes this is super cool! Quick question are you talking about this feature? https://docs.cloud.google.com/vertex-ai/generative-ai/docs/b... Because it’s just using structured response so it should be doable with Gemini 3 ? (We are using Gemini 3 for some docs processing and its visual understanding is just incredible)
