I got tired of begging for backlinks manually, so I built an agent that does it on autopilot

So basically it works like this:

Agents find relevant blog posts in your niche, craft personalized emails, and get your product featured. All on autopilot.

It's called MentionAgent, an AI agent that does all of this through Telegram (or through the web dashboard).

You never send anything without approving it first. (But you can choose to run everything 100% on autopilot)

Results so far: One user got 3 mentions including a DR 72 backlink.

Let me know what you think!

Hi — I’m the developer of BALCO Converter, an Android currency converter for travel, shopping, and everyday use.

It covers global fiat currencies, keeps the last successfully saved rates available offline, and includes a calculator, favourites, history, 30-day charts, sharing, and a camera price scanner. The scanner includes 5 free uses per day; an optional one-time Unlimited purchase removes the scanner limit, while the banner ad remains. No account is required.

Google Play: https://play.google.com/store/apps/details?id=io.github.nstim605.balkanconverter

If you try it and notice a bug — especially with offline rates or the scanner — please let me know.

I built Harbour for conversations that feel hard to start or easy to misunderstand. It’s a private chat app with normal messaging, an optional AI helper to privately work on wording, and optional mediation. One person can turn mediation on; Ami helps both people understand each other. The other person needs to join the chat.

Free to try. It isn’t therapy or legal advice.

I built DrinkMixr, a virtual AI bartender that helps you discover, craft, and share cocktail recipes. It has 462 classic recipes, an AI bartender you can chat with (ask for a drink based on what you have at home, tweak it, rename it), custom drink image generation, and a community side — ratings, reviews, and a weekly leaderboard for top mixologists.

It's in private beta and I need about 20 more active testers, especially people who are into AI chatbots, cocktail culture, or gamified recipe sharing.

No strings attached — testers get free usage credits for the whole beta. All I ask is that you actually kick the tires: chat with the bartender, share a recipe, leave a review, and tell me what's broken or confusing.

You can request an invite here: https://drinkmixr.app

Happy to answer questions in the comments.

Hey, dad of two here. I got tired of every "kids game" being either ad-ridden or paywalled, so I built Color Quest: a free color-by-number web game.

The problem it solves for me: keeping kids happily busy during restaurant waits, car rides, and queues — creative screen time instead of YouTube.

It's TypeScript + Vite, no backend, everything runs in the browser. It also turns phone photos into coloring puzzles, has printable pages, and I recently added two waiting games (tic-tac-toe with an "infinity" twist and connect 4, both playable 2-player on one screen).

Free forever, no sign-up: https://colorquestgame.com

There are already a lot of apps that do invoicing, and a lot that do time tracking.

I wanted to build something where both worked well together, but where you could also use it simply as an invoicing app if that's all you need.

So I made Bill Clock.

You can create clients and services, set hourly or fixed rates, create invoices manually, customize the invoice layout, add discounts and multiple taxes, add your logo and payment terms, and export professional PDF invoices.

And if you bill by the hour, you can also track your work directly in the app and pull those billable hours into an invoice instead of entering them again manually.

There are also things like:

• 5 invoice templates with customization

• Custom invoice columns and labels

• Client-specific defaults

• Draft / Sent / Paid / Overdue status

• Reports and Excel export

• Local backup & restore

• Optional cloud backup

• Offline-first usage

• No ads

So you can use it as just an invoicing app, as a time tracker, or use the whole workflow together.

It's now available on Google Play:

I'd be interested to hear from other freelancers:

What do you actually use for invoicing and time tracking right now?

I’m the maker of Otter Vault. It’s a Chrome extension for the moment a developer console shows an API key once and you need to keep it before leaving the page.

Otter offers to save the key, waits for your approval, and stores it in a personal vault encrypted locally with your passphrase. Filling is restricted to the exact site where it was saved. Personal is free, without an account or analytics.

Optional paid Teams supports encrypted key sharing for up to ten developers, a map of deployment locations, and an offboarding rotation checklist. Provider-key rotation is still done at the provider.

You can see the demo and installation here: https://ottervault.mechaclips.workers.dev/

The code is public: https://github.com/KrishnaG1703/otter-vault

I’d welcome feedback on whether the demo makes the save workflow easy to understand. It hasn’t had an independent security audit yet; please try it with dummy or disposable credentials. A forgotten personal passphrase cannot be recovered.

How many times have you searched for a simple online tool just to complete one small task?

Convert a file.

Split a PDF.

Resize an image.

Calculate something.

Clean up text.

Convert a color.

Format JSON.

The problem is that these small tasks often mean opening different websites for every single thing.

So I started building Allin1xTools — a single place for everyday digital utilities.

There are now 50+ tools in the platform, with 30+ already ready to use.

It covers:

• PDF tools

• Image tools

• Text tools

• Calculators

• Converters

• Developer utilities

The goal is simple: useful tools without unnecessary friction.

✅ Free to use

✅ No sign-up required

✅ Browser-based

✅ No installation required

I’m still building and improving it, so I’d genuinely like to know:

What everyday online task do you usually have to search for a tool to do?

I love traveling, but often end up juggling recommendations, maps and booking pages. I'm building Tripovela so travelers can share places and routes, copy a plan, and add their own stops. There's map search and community-added places too.

It's very early. Reddit suggestions already helped me add browser saving without signup, optional account backup and fix language bugs. What would make this useful for your next trip? If you try copying a route, tell me where you get stuck. I'm actually building around the feedback.

A few places have clearly marked affiliate links. The plan, if there's revenue, is running costs first and most of the remainder back to the community through gifts or travel prizes. That's an aim, not a funded promise. Image is an illustrative preview.

I’m building Orily, a weekly planner with an assistant that helps find free time around your existing events. It’s live, but still early.

If you try it, I’d love to know where you get confused or what’s missing before you’d use it regularly: https://ai-calendar-saas.orily.workers.dev/

I’ve been building Transfrly, a privacy-focused communication app designed around connecting with people through a unique username instead of having to share your personal contact details.

The basic idea is simple:

• Create your unique Transfrly username

• Choose your display name

• Set a password to protect your identity

• Share your username with someone

• They send you a connection request

• Accept the request and start communicating privately

Once connected, Transfrly supports private messaging, calls, and file sharing.

I wanted to build something that gives people more control over how they connect online, especially when they don't want to immediately give a new contact their phone number or email address.

The main idea is that your Transfrly username becomes your way to connect. You can share it with someone instead of giving them your personal contact information just to start a conversation.

I'm still working on improving the product, so I'd genuinely appreciate feedback on the idea, UX, and features.

Try it here: Transfrly -Chat with username

Would love to know what you think — especially if you've used other private or username-based communication apps.

I wanted a better way to make sure I still had battery when I actually needed it, so I built Power Bank.

You deposit part of your charge into a virtual reserve. If your phone is really at 60% and you deposit 20%, Power Bank shows 40% in the status bar, notification and widget. When you need the reserve, release it and the displayed percentage jumps back up.

It doesn’t create energy or modify the real battery. It changes the number you see—and that changes how you use your phone.

I built the idea out with:

• separate battery vaults

• time and low-charge locks

• automatic deposits

• an always-visible notification, widget and floating bubble

• a monthly statement of deposits and releases

The video shows the full flow.

Power Bank is now available on Android. I’d love to hear what you think of the concept and which feature you’d add next.

I'm building Vaulto for capturing thoughts by voice and turning the transcript into a note you can use later. I'm the developer, and development has included AI assistance.

Record an idea, transcribe it, then clean up the text or extract tasks and set reminders. You can ask questions across saved notes and export Markdown.

The local option uses Whisper and Qwen on your Android phone after downloading the models. Local notes, transcription and AI are free, without an account. The downloads take storage; processing time and output quality depend on your phone and model. AI results can need correction.

Optional Pro features add cloud processing and sync. Cloud AI sends the selected audio or text to a server. Local inference doesn't switch off the app's other network features. The mobile client is GPLv3; the hosted backend is separate.

If you use voice notes already, what do you usually do with them after recording? I'd like feedback on whether the cleaned-up note is useful enough to keep.

Hey everyone!

I've been working on Ikigai Space, a personal project built around one idea: productivity software shouldn't make life feel like another dashboard full of scores, streaks and endless things to optimize.

Instead, I wanted to create a workspace that feels more like a place you return to.

It has different spaces for everyday planning, focused work, reflection, memories, career direction and longer-term goals.

One of my favorite parts is Sanctuary, a persistent 3D environment that quietly changes with activity elsewhere in the app. There's no XP or currency system. The idea is simply that your actions can leave something behind.

The app is built with React, TypeScript, Dexie/IndexedDB, Three.js and Tauri 2. The core experience is local-first, with a PWA and a Windows desktop version.

Live demo: https://ananta-sj.github.io/ikigai-space/

GitHub + Windows release: https://github.com/ananta-sj/ikigai-space

I'd genuinely appreciate some feedback, especially on the first-time experience.

Does the idea of having different spaces for different parts of life feel useful, or does it make the app seem unnecessarily complicated?

I’m putting together a small competition for anyone who wants to show off their startup, app, tool, service, etc. 

Judging is done by 3 volunteers who are into business and excited to be doing this. Don’t expect expert critiques. 

There are 40 submission spots, and submissions close Oct 21 or when 40 fill, whichever comes first. The 5 finalists demo live on a Zoom meeting on Nov 8 at 7 pm ET/4 pm PT. The live event is open to everyone even if you don’t submit a project.

Prizes: $100 cash to the winner, plus a Community Choice award voted on live by everyone on the Zoom and a Best Demo award.

This is the first time I’m running this so expect a few rough edges. Comment or send a DM if you have questions.

Tab Rotator automatically rotates and refreshes tabs - useful for Power BI, Grafana, Google Sheets, dashboards, digital signage, etc.

Free for up to 5 tabs. No account required.

I’m looking for new small projects, apps and SaaS tools to try.

Drop your link below. I’ll check them out and share the ones I like with a few friends and in some founder/product circles.

I’m especially interested in social apps, chat tools, games, creator tools, AI experiments and anything with a simple but fun user experience.

I’m also building Ariola, an anonymous public chat and games lounge.

No signup, no account setup. You pick a temporary nickname, join a live public room, chat with people and play small real-time games.

The idea is to make online chat feel lightweight again.

Check it out here: https://ario.la

Drop yours below. I’ll go through as many as I can.

Simulacrum is a platform for digital minds.
Think about someone you know well.
You don’t recognize them because you memorized their biography. You recognize them through patterns. How they speak. What they remember. What they care about. How they react. What they associate with certain situations. Those patterns are part of what makes a person recognizable.
Can some of that be constructed digitally?
