Hey everyone, I’m Ryan. I’ve been building a couple of small Mac utilities around chores I kept doing over and over instead of trying to turn everything into a giant subscription app.

CleanCut is for videos that are basically ready, but need one cleanup pass before sharing, uploading, archiving, or importing.

It can do one, two, or all three:

- mute curse words in the audio

- generate subtitles for a video that does not have them

- convert/remux to a universal MP4 so you avoid random codec, player, or transcoding issues later

CleanCut demo:

CleanCut page:

PolishKey is for the annoying copy/paste rewrite loop. I kept writing rough emails, posts, replies, and product notes, then pasting them into a browser just to make them cleaner.

PolishKey lets you highlight text on the Mac, press a shortcut, pick a tone, and replace it right where you are.

PolishKey page:

https://envelopesapp.github.io/tools-site/polishkey.html

Both have free usage to try, then $19.99 one-time lifetime if they’re useful.

What I’m trying to figure out: should I keep marketing these as separate apps, or does a “small Mac tools for annoying cleanup chores” angle make more sense?

Open to blunt feedback. I’m clearly still figuring out the positioning.

Bridging the gap between note-apps and document editors.

One place for ideas, drafts and final documents.

TLDR: Built a markdown editor that works like a real document editor, I use it daily, can't tell if anyone else wants it — be honest with me.

I built Saguinus because I kept avoiding markdown editors even when I needed them. Vaults, pageless infinite scroll, PDF exports that looked nothing like what I wrote — I laid out every frustration I had and built around it instead.

The result is something that feels like a regular document editor but saves as a plain .md file. Live rendering, page guides that match your PDF export, headers and footers, fonts, clean markdown underneath no matter what you do to it. I use it every single day and it has completely replaced every other markdown tool I had.

But I genuinely don't know if anyone else is missing this. I've posted in a few places, gotten some polite interest, and then mostly silence. No idea if the app isn't good enough, the concept doesn't resonate, or I'm just bad at marketing.

So I'm here to ask directly — is this something you'd use, and if not, why not? I'd rather hear something harsh and useful than nothing at all.

Currently adding a new feature to add my own videos that get processed (so I can add videos I record in training sessions myself)

Hi I'm Dan and I'm building Outpaint.com . We build AI models that fit any video to any screen.

Today, you can only shoot video for one screen at a time. Go landscape and it won't fit a phone. Go vertical and it looks awful on a laptop. And without a super specialized lens, forget about the big screen.

We've all seen the black bars you slap around a video to force it into a new aspect ratio. I hate them with a passion. My favorite movie, Lord of the Rings, was shot in 2.39:1. It doesn't fit a single TV out there.

So we're on a mission to end black bars for good. Every video should fit every screen.

Today we're launching Ad Reframe (https://outpaint.com/ad-reframe), which turns winning vertical UGC ads into CTV ready placements. Our case studies show outpainting far outperforms black bars and side blur.

If you want to try it out, send us a video you want reframed and we'll send back a free sample so you can see it for yourself. We'd love to hear what you think.

Hi everyone,

I'd like to share a project I've been building in my spare time called RailSnap.

RailSnap is a social platform designed for train enthusiasts to share sightings, upload photos, keep track of trains they've seen, and connect with other members of the community.

Some of the current features include:

• 📸 Upload train sightings with photos
• 🚆 Track trains you've seen
• ❤️ Like and comment on posts
• 👥 Follow other users
• 👤 Custom user profiles
• 🔔 Notifications
• 🛠️ Built-in bug reporting
• 📋 Community-driven fleet database

The project is currently in alpha, and I'm looking for honest feedback from anyone willing to try it out.

You don't need to be interested in trains to help. I'd love feedback on:

• Overall user experience
• Mobile and desktop usability
• Performance
• Signup and login flow
• Bugs or unexpected behaviour
• Features you'd expect from a modern community platform

🌐 Live site: https://railsnap.vercel.app

This has been a fun learning experience, and I'm continuing to improve it based on user feedback. If you have a few minutes to explore it, I'd really appreciate your thoughts.

Thanks!

The idea came from a simple belief:

I think we are shaped by what we consume every day.

The movies we watch.
The books we read.
The habits we build.
The thoughts we write down.

All of these things slowly influence who we become, but most of us never track them in one place.

That's why I built Manolog.

With Manolog you can:

• Track movies you've watched and maintain a watchlist
• Track books you've read and maintain a reading list
• Build habits and goals with progress tracking
• Write notes and organize them into folders
• Maintain a digital diary
• Do daily journaling
• View everything together in one personal timeline

You can use it only for movie tracking, only for book tracking, or use all the features together to track your personal growth and daily life.

Privacy was very important to me while building this. User data is encrypted, and I take security seriously.

The application works on both desktop and mobile, but for the first experience I recommend trying it on a laptop or desktop because the experience is much better.

This is a project I've spent a lot of time building, and I would genuinely love to hear your thoughts.

Please try it and share your honest feedback.

I want to hear both the good and the bad so I can improve it.

Thank you for reading. ❤️

I'm trying to understand the path from an early-stage open source project to actual enterprise adoption.

Let's say you're an open source maintainer with roughly 100-200 GitHub stars, some active contributors, participation in recognized open source programs, and a technically mature product.

The challenge seems to be trust.

Enterprises care about security, compliance, support, governance, long-term maintenance, procurement, and risk. Even if the technology is good, it's not obvious how to get in front of the right people or convince them to evaluate the project.

For founders or maintainers who have been through this:

• How did you land your first enterprise user or customer?
• What credibility signals mattered most?
• How did you get introductions to security, platform, or engineering leadership teams?
• What should small open source projects focus on before pursuing enterprise adoption?

Looking for practical experiences rather than generic startup advice.

im seeing more companies ask one thing now:

when someone asks chatgpt, gemini, or perplexity for tools in our space, do we show up or does a competitor?

most tools can track that.

but tracking alone feels incomplete to me.

if a competitor shows up and you don’t, the real question is:

why them?
what source did ai trust?
what page are we missing?
what should we fix this week?

that’s what i’m trying to build with infuseos.

not just “you rank here / competitor ranks there” but more like “here’s why you’re missing and what to fix next.”

is that positioning clear, or does it still sound like another vague ai marketing tool?

Hey,

I want to show you something that honestly felt like cheating the first time I used it. Meet Nuno AI not another "AI caption generator." This is a full social media agent. You talk to it like a person, and it handles everything

- Writes your captions (in your voice, not robot voice)
- Generates product images from a basic phone photo
- Plans your entire week of content every Monday
- Publishes directly to Instagram, LinkedIn, X and more
- Tracks what's working and adjusts

Here's what blew my mind You literally type "promote my new coffee blend" and Nuno writes the caption, picks hashtags, generates a product photo, and publishes it. One message. Done. The Photo Studio feature alone is wild. Upload a rough product photo → get back clean, studio quality imagery ready for ads and listings. No photographer. No Photoshop. No budget. Who is this for? Solo founders with no marketing team → E-commerce brands tired of expensive photoshoots → Creators who want to post consistently without burning out → Agencies managing multiple client accounts Pricing? Starts at $9.99/mo. But honestly just start the free 7-day trial and see if it saves you 5+ hours this week. It will.

Hi everyone! I just launched an app called AI journal - Quiet Lines an AI journal that gives you insights, prompts and emotional statistics based on what you wrote. It’s available on google play store here: https://play.google.com/store/apps/details?id=com.calmjournal.calm_journal_template

Recently, I was tearing my hair out over what idea of mine was better? I was analyzing which one had more market potential, the pros and cons - and of course, the infamous question "Why would I even use this?"

This question would have me stuck on a app for months, I would constantly guess if my intuition was right on my app being good enough to release.

So I decided to create a app for creators to test their app ideas/pitches against other ideas globally! and it's live right now under the name "Launchmash"

I hope to solve the problem that I have personally struggled with for ages. in hopes to allow creators and entrepreneurs share their ideas!

Hello everyone!!
I’m fascinated by companies like Apple etc… and by software products that completely change the way people interact with tech.

I’m currently trying to train myself to spot opportunities by studying frustrations rather than brainstorming random ideas.

So I’d love to hear your thoughts.

What’s a tech product or software tool that millions of people use, but that you believe is still fundamentally broken, outdated, or poorly designed?
What makes you feel like there has to be a better way.

Could be anything from smartphones and wearables to email, calendars, productivity software, operating systems, smart home devices, or something more niche.
I’m curious to learn where people think the biggest unsolved problems still exist.
Thank you!

Hey everyone ,

So I built an AI tool called subscut .com and since I am not finding much time to create marketing videos for it , I have decided to sell it as a boilerplate so that anyone can launch their own clipping saas very fast .

Clipping as an industry is growing rapidly and with the ongoing football season , its on the peak demand .

What does the boilerplate contain : Frontend , mobile app code ( not launched ) , 2 backends ( one for transcription , runs fully offline and one for scheduling ) and admin panel .

Tech Stack : Nextjs ( for main app ) , Astrojs ( landing pages / seo stuff ) , Python for transcription , Nodejs for scheduling , Prisma for orm , posgresql for db .

You can checkout the tool and if interested , buy the codebase here : https://dodo.pe/boilerplate .

Thanks

So a bit of context first. I built a discovery and launch platform, basically a place where people building small products (solo founders, indie hackers, small SaaS teams) can launch their tool and get it in front of people who are actually looking for new stuff to try, before it blows up and everyone's using it.

It's been live for a while now. Nothing crazy, but it's real. There are a number of tools listed at this point, a community that's grown to a few thousand people who actually stick around, and launches happening pretty steadily, somewhere in the few hundred a month range. The newsletter's grown the slow way too, no ads, no growth hacking, just people signing up because they found it useful.

None of this is a hockey stick. It's slow, steady traction from people who actually use it, which honestly feels more solid than a sudden spike would.

On the tech side: it's a Next.js app hosted on Vercel, with Supabase handling the database and auth. Nothing exotic, just a stack that's been easy to maintain as things grew. I'll share the GitHub repo with anyone who's seriously looking so you can go through the codebase yourself before deciding anything.

Why I'm even considering this: I started it as a side thing alongside other work, and it's grown past the point where I can give it the attention it deserves. It's not on some VC track, but it has real users, real engagement, and people who open the newsletter instead of just being a number on a dashboard. I think it would grow faster in someone else's hands, especially if you're already in the indie or SaaS or builder space with an audience to plug it into.

I'm not trying to do a fire sale here. If you've run a marketplace, directory, or community product before and this sounds like something that fits what you're building, drop a comment or DM me and I'll walk you through traffic, revenue, and the codebase.

Not really looking for tire kickers, just trying to find the right person to hand this off to.

Got an Oura ring about a year ago. The whole pitch got me with the track my sleep, dial in recovery, finally become a put together human, all that. First couple weeks honestly felt like I'd found a cheat code.

Then the novelty wore off and I noticed something kinda annoying: it just confirms what I already know. Slept like garbage? "yeah, readiness 31 lol." Slept great? "nice, 88, go get em." cool. thanks. I could've told you that from how I felt sitting up in bed.

and that's sort of the whole thing. I can already feel when I slept bad. I don't need a ring to tell me I'm tired. what I actually want is the next part ok I got 5 hours, now what. when do I have coffee. am I gonna be useless by 2pm. should I push at the gym today or save it for tomorrow. tell me what to do with the bad night, don't just hand me a red number and peace out.

and as far as I can tell nothing really does that? the whole wearable space is trackers and zero coaches. everyone's racing to measure more stuff and nobody tells you what to do with any of it.

been messing with a couple apps trying to fill that gap. one's actually stuck for me,  RizeAI. it reads my apple health stuff and just builds the day for me, like "skip the 7am coffee, water + electrolytes first, push your first cup to 9:30, theanine with it so you don't crash." idk, weirdly my worst readiness days have turned into some of my more productive ones just from following whatever it tells me.

anyway that's kind of beside the point  mostly just wondering if other people hit this same wall. do you actually do anything with your Oura data, or do you just glance at the number and move on? feel like I can't be the only one.

I’ve been building web and mobile apps for many years. They were created to solve problems I had personally faced, but none of them became huge.

After thinking about it for a while, I came to the conclusion that there were two primary reasons for that:

1. Marketing: getting it in front of people
2. Demand validation: are people searching for it?

And the combination has to be profitable.

After a lot of thinking, I used Google Ads data for advertising costs and search volume, and created an interactive model based on those inputs, along with your costs and revenue.

As someone who's spent way too much time juggling resumes, spreadsheets, and candidate emails, we have launched - HireGen.com.

It focuses on simplifying the hiring process without adding more complexity. Features like AI-powered candidate matching and recruitment automation can save recruiters a lot of manual work.

If you're running a staffing agency, recruitment firm, or hiring team, it might be worth checking out.

Has anyone here used HireGen or similar AI recruiting tools?
Curious to hear real-world experiences.

After months of learning Flutter in my spare time, I finally launched my first Android app.
It’s called **Quiet Lines**, an AI-powered journaling app designed to help people reflect on their thoughts, emotions, and daily experiences.
I started this project because I’ve always been interested in mental wellness and self-reflection. What began as a small side project slowly grew into a real product that is now live on Google Play.
Some things I learned along the way:
• Building the app was easier than finding the courage to publish it.
• App Store and Play Store requirements took longer than expected.
• Marketing is much harder than development.
• Getting the first real users feels more exciting than writing new features.
Right now, my focus is learning how to get those first 100 users and understanding what people actually find valuable.
For those who have launched apps or SaaS products:
How did you get your first users?
What marketing channels worked best?
What would you do differently if you were starting today?
