Our opinion is that you need to rethink the UI from the ground up, which isn't a tractable proposition through an extension or an MCP server :)

Show HN: Avec – iOS email app that lets you handle your Gmail inbox in seconds

Hi HN!A few friends & I have just spent the past ~2 years building a new kind of email app for iOS. It's now available in GA and we think some of you might find it interesting.Why another email app, you ask? We think that while many interesting attempts at one-upping Gmail were made in the past 25 years, no one could really solve the core problem we all experience with email: information...

This looks awesome! I wish I could connect to my Postgres DB using SSL.

Show HN: Chrome extension for skimming HN comments using gpt-4o-mini summaries

https://github.com/jnnnthnn/hn-comment-summaries

Hi HN!I love reading the comments under HN submissions but I often get overwhelmed when I'm skimming threads to find interesting ones. To make my life easier, I built a Chrome extension that generates small summaries for each comment in a thread.When you load an HN submission page, the extension reads comments (with their context), pushes them to gpt-4o-mini for summarization, and inserts the...

Interesting! You should consider making the email field optional: it’s unclear why it’s required, and maybe folks will be more comfortable sharing if it is optional.

Perplexity offers a Reddit "focus" which does exactly that! https://www.perplexity.ai

Thanks for the kind words!

Yes, the underlying dataset very much conditions the quality of the responses. Additionally, the retrieval strategy is also a really important factor (and that is something which I haven't had time to extensively optimize).

I'm writing a blog post that will answer your questions! Will post it here when it's fully baked.

Thanks for flagging! Actively debugging, looks like one of my DB vendors is having some uptime issues. If you retry a couple times you should (eventually) get lucky.

Hey! Not open source, largely because I don't have time to make it good enough for me to feel comfortable sharing what's otherwise pretty scrappy code, but I'm planning a blog post detailing how it was built.

Tech stack is https://news.ycombinator.com/item?id=40238913 + the addition of turbopuffer for the new functionality.

X links are currently broken on HN and don't work with threads on archive.is. Alts:

X.com links are currently broken on HN so I posted a screenshot instead

No. It will get offered to you once you exceed the monthly GPT-4o limit (currently 5 to avoid breaking the bank).

GPT-4o outperforms all local models so I figured using it as a fallback was the right approach :)

Ask HN: X.com Links Broken on HN?

Posted by jnnnthnn on Friday May 17, 2024 @10:55AM
from the ask-hn dept.

I think the twitter.com -> x.com migration broke X.com on HN. See https://news.ycombinator.com/item?id=40390595 and a few broken examples at https://news.ycombinator.com/from?site=twitter.com/x

I made the caching window substantially longer (2 days instead of a few minutes) upon noticing most queries weren't about current events, and fixed a bug in the cache resolution logic that'd lead to a substantial number of cache misses.

Thank you!

Thanks for the feedback! That feature is there, just not discoverable enough!

Try clicking on the relative time (e.g. "over 1 year ago"). Should take you immediately to that comment on HN, and you can then hit back in your browser to return to Hacker Search.

Agreed on the extension. That's coming next!

I’m so glad you like it! Thank you for taking the time to write this kind note.

Hey! This leverages the official HN API (https://github.com/HackerNews/API), no scraping involved. I don't think it's my place to opine on "who owns the posts".
Re:Show HN: I built a LLM-powered Ask HN: like Perplexity, but for HN ... on Thursday May 16, 2024 @08:08PM (#40384901)
Yeah, that'd be a really nice thing to have! My current (and naive) approach is to just limit to the last 3 years of data. That said, it should be easy to add a date filter as a first step, and potentially have a more ingenious approach for letting the LLM reconcile contradictory statements based on the time at which they were posted.
Re:Show HN: I built a LLM-powered Ask HN: like Perplexity, but for HN ... on Thursday May 16, 2024 @06:50PM (#40384280)
I feel that it performs really well on queries like those on the landing page, that generally have to do with understanding HN's sentiment about something or finding resources to learn about a topic.

As to your second question, someone looked up “What are some famous Google office pranks?” (https://hackersearch.net/ask?q=What%20are%20some%20famous%20...?) earlier today and I found some gold in there. Some of the hot takes on Gary Marcus have cracked me up too (https://hackersearch.net/ask?q=what%20do%20you%20think%20of%...?).
