It's been a blast building on #gpt3 since August. 😆

I've built and shared a few dozen apps and prototypes.

I often get asked this, so...

Here's a list of some favorites! 👇
1) ⚡️Official @OpenAI x @zapier integration

This is the most popular by far.

Originally an unofficial integration I built for myself, it is now powering the next generation of #AI x #NoCode tools.

2) 🔀Fuzzy Compiler

Turns "fuzzy/sloppy" code into clean code.

It speeds up my build a ton. It's mobile optimizes so I can generate code and add to Replit mobile app while I'm bouncing our baby down in the Ergo.

3) 🔕Error Analyzer

Analyzes error codes and spits out analysis + fixed code.

I don't use this as often, but helpful in debugging if my Fuzzy Compiler code doesn't work right.

4) 🕳️Mini Yohei - Founder Portal

This is a series of AI services for our portfolio companies in our founder portal.

Excited to add lots more!

5) 📄Deck Parser

Scrapes a PDF deck and extracts structured data.

Works on startup decks and VC decks.

6) 📰Due Diligence Support Tool

Identifies key risks based on a startup description.

This September version has improved a lot since, and...

7) ✍️AI Memo Drafting Tool

I combined the deck parser + DD support tool + more to build this.

This tool can draft an AI investment memo from a URL, description, or deck.
8) 📩School Email Summarizer

I made a personal web app that shows me summaries of all emails from my kid's school.
9) 📨emails.wtf

Then, I built a generic version of this.

If you email any email address: eg. x@emails.wtf, you will get a summary emailed back to you.

Access all summaries from a web app.
10) 🪄Magical To-Do List App

Built a folder in @todoist where I can add emails I need to send, and the AI drafts an email in gmail for me.

11) 🛠️Geppetto.me

I built a #nocode AI tool with #nocode.

Built on @softr_io, Geppetto allows you to quickly prototype #gpt3 based apps.

A lot of the apps you see above were initially prototypes with this.

12) 💬Mini Yohei Chat Bots

I've built 4 chatbot prototypes for founders.

- Pitch Mode: collects data
- Mentor Mode: helps founders with questions
- Guidance Mode: guides founders through a workshop
- Mean Mode: gives mean feedback

Mentor Mode:
13) 💕Healing Poetry

Stressed?

This app will write a beautiful poem to cheer you about about whatever is stressing you out.

Zero data stored, go try it!
14) 📢GTM Strategies

Identifies 7 specific go-to-market strategies based on a startup description. Was used 500 times in the first ~24 hours.

15) 🗞️Daily Tech News

Set up a Zap that scraped Techmeme and send me a summary every day.

I read this most mornings :)

16) 👍Sentiment Analysis of ProductHunt

Added capability into our memo drafting tool to scrape ProductHunt and generate a sentiment analysis report.

17) 🧑‍💻LinkedIn Bio Generator

Similarly, this scraped a person's LinkedIn and generates a bio.

18) 📲GPT-3 Siri on iPhone

Published a template for "talking" to #gpt3 via Apple Shortcuts:

Relevant (but separate), this one is for Stable Diffusion:

My 3 yr old can use these :)
19) 🌀Latent Blog/Search

A fun experience on what a parallel internet might look like.

This blog and search engine are fake. They make everything up as you click through.

Latent Blog:

Latent Search:
20) 🖼️Startup Graphics Generator

Not #gp3, but it's @OpenAI so let's count it.

This tool generates 100 startup friendly graphics of varying styles from a simple prompt.

21) ❓Q&A with Airtable without embeddings

While I love semantic search, it's not always the best solution.

This @airtable extension is fed the schema of the whole Airtable and identifies the table and column to search based on any query.

There's a lot more where this came from!

Check them here: yohei.me (my build-in-public log)

I'll probably keep adding to this thread, because I'm clearly going to keep building 😁

i heard @pocket is shutting down...

so i vibe coded* a quick free open source prototype with some AI features called KeepYard

(*still has issues, but i challenged myself to push this in one night)

link/github below 👇
you can try it here: keepyard.replit.app

(also sometimes works on keepyard.com but got stuck on CORS issue before bed)

it's a pretty straight forward bookmark manager with categories you can set, free form tags, favorites Image
you can add bookmarks from the web UI, which will grab metadata (description, image, etc.) for you Image

i vibe coded a startup intelligence platform

introducing VCpedia

startup funding discussions, captured on @x, analyzed with @openai, enriched with @exaailabs, daily newsletter using @resend. built with @replit agent

daily newsletter & more 👇 Image
if you just want the automated daily newsletter, subscribe here:

(sample image attached)

random thoughts on the tool and building it below vcpedia.comImage
this wasn’t even something i planned on building but the idea came to me a week ago, and I put other builds* on hold to throw this up (it’s when I work fastest)

(*untapped crm, pippin, etc)

very excited to announce something we've been working on...

introducing Agent Fund led by @alexreibman, @AtomSilverman, and myself:

- VC fund focused on AI agents: apps, infra, tools, etc.
- small checks in many agent companies
- angellist rolling fund (public fundraise)

more 👇Image
to apply to invest in the fund, or to apply for funding, go here:

this is an @angellist rolling fund, so...

- open application for accredited investors
- set up as quarterly subscriptions
- $40k minimum ($10k/qtr, 4 quarter minimum) agentfund.comImage
the ai agent space has been heating up through 2024, and now is the time for this!

check out these trends @langchainai noticed last year:

- langsmith users using langgraph (7% > 43%)
- % traces using tool calls (3% > 34%)
- avg # of steps per trace (3.1 > 11.2) Image

this is for the minimalist coders 🫡

open-sourcing pippin-lite!

a minimalist template for a dynamic self-building autonomous agent

with only 227 lines of code, it can connect with X, github, airtable, etc. and execute self-written code!

github/more 👇 Image
given the pippin framework is a spiritual evolution of babyagi, felt fitting to call this babyagi-2o extension: pippin-lite. it adds dynamic tools/auth via @composiohq

make sure to check out the pippin framework if you haven’t (QT’d here)
it’s basically a single LLM loop that has access to the 250+ composio tools, with fallback to writing/updating new skills and installing required imports

github:

designed for close ended tasks, it’ll loop through a couple approaches until it’s complete (or gives up)github.com/pippinlovesyou…

here we go…

open sourcing the $pippin framework!

for launching digital beings like @pippinlovesyou

- character config
- reusable and dynamic skills via @composiohq
- activities w/ cool down, etc
- memory mgmt

here’s a ~4 min super cut of the live demo

github & more 👇
github:

quick background: @pippinlovesyou the unicorn is a digital being operating 24/7, taking naps, going on walks, and occasionally communicating w the human world

during a winter break refactor, decided to open source as a framework.github.com/pippinlovesyou…
core loop is activity selection and execution, which kicks off after configuring your character and choosing an LLM (and adding api key)

auth into composio tools for dynamic skills or add your own in the skill folder. then build activities that use these skills! Image

woah what a week, @pippinlovesyou has 8k+ followers and had his first livestream this weekend.

the meme coin inspired by pippin has 18k holders and the telegram has 4k+.

this thread from Monday captures the first 36 hours so I’ll drop it here. to summarize:

- posted a pic of a unicorn generated by AI
- upon request, used AI to name it
- a meme coin started
- i jumped in
- decided to turn pippin into an AI influencer
i used Claude to generate some pippin animations and made a site where you can try them out
