this seems financially irresponsible for Replit, haha, but is very awesome for users. we're in a new phase of AI where cheap models are powerful enough to do lots of real work, with the right harness and environment.
Replit Free Mode, powered by @OpenAI GPT-5.6 Luna. Let’s make intelligence accessible to everyone.

I mostly have very bad ideas, but it's much nicer to learn that by building them than to go on thinking they’re good because I never tried. Not having to wait til I'm at a keyboard makes such a difference.
Your ideas. Anywhere they find you. The redesigned Replit mobile app is available now on iOS and Android.

I love how AI lets me be more impulsive at work with less downside. Lower cost to firing off some idea to see how it turns out. I hope Replit helps people be more instinctive in this way. Quote from Montessori about the kind of work we should strive for:

Synthesis mentioned on Diary of a CEO podcast with @StevenBartlett. Love to hear these stories about students enjoying working with the Tutor.

I either completely wasted a Saturday or just discovered a new hobby. I could not find a simple little program to teach my kids typing. Everything had a ton of malware or included chat rooms I didn’t want for my elementary age kids. I also wanted one that would help them with their spelling and vocabulary words. So I gave Ai a try and built my own. I have ZERO coding knowledge and basic tech skills. This was my first ai project. It took me several hours because I kept adding features and had to learn how to “talk” to the developer to get the results I wanted. I’ve worked with a software developer before and when I started talking to the system like I did our developer, it worked better. A few things I noticed: 1) user management and databases were tricky. Creating the program was easy but tracking progress, logins, teacher accounts and assignments were hard to “stick”. It wouldn’t track progress and users kept getting lost. So the “developer” had to be trained and I had to google the correct terminology to describe what I wanted. Creating the relationships with parent accounts and teacher accounts was easy once I learned to communicate better. 2) describing the UI I wanted was frustrating and I gave up. Screen shots, arrows and lots of descriptive text got us this far, which isn’t far at all. Alignment and text wrapping cannot be taken for granted. 3) you can’t assume it knows to get outside information, you have to tell it. I wanted it to create sentences to practice typing using vocabulary words and it kept creating hilariously wrong sentences that kept me and the kids laughing, to make it actually create real sentences using the vocabulary words it kept wanting me to give it the definitions and then it just described each word exactly as I wrote it. I finally had to tell it to use a dictionary api and only use sentences found in the dictionary. That worked. All in, we created a usable website (designed for desktop since it is a typing tutor). I plan on sharing it with the kids’ classes because we were all looking for something like this and we will actually use this regularly. Would love to know what you think! Feel free to use for your kids. Set up a family account, then add your kids and let them compete against each other. Link to the program below in the comments (if it looks bad on your phone it’s because it’s for desktop)

I could write ui code without looking at the output and do better than the new Apple photos app.

Sure, making apps at the gym is cool, but doing it on the toilet is still the most goated.
Whatever you need… make an app for that. Now on your phone. For everyone. Free.

I'm fully whitepilled on desk treadmills after a couple weeks. I love coding and I love walking... ¿Porque no los dos?

My modern equivalent of using the whole animal I kill is reusing our Amazon Fresh bags to dispose of recycling. I am one with nature.

Built this product a day with @Replit Agent: AI Card Designer - Create personalized greeting cards using AI * Google signup (Firebase) * Stripe for credit purchases * OpenAI for image generation Didn’t write a single line of code. Even prompted the Agent to write the prompts.

I hate the meme from AI influencers that not being able to prompt coding AIs well is a "skill issue". It's not wrong, it just hurts that it's still true. We need to build better interfaces for prompting.

Prompt composing tools should help you understand the limitations and strengths of the AI you're instructing, automatically break your instructions into manageable pieces, provide real-time feedback on when more or less context might be helpful, etc.

Replit Agent—coming out of early access today—is the best way to go from an idea to a deployed app. Afterward, you'd want to iterate on features and fixes quickly. Enter Assistant—prompt to change at the speed of thought!

Object permanence is underrated. Literally a nightmare without it.
Introducing Oasis: the first playable AI-generated game. We partnered with @DecartAI to build a real-time, interactive world model that runs >10x faster on Sohu. We're open-sourcing the model architecture, weights, and research. Here's how it works (and a demo you can play!):
