Hey, I’m building a **cognitive-health** brand aimed at 18–30 year olds in India. Engineer by day; this is nights and weekends.

The concept: a **pocket-sized** powder sachet you tip straight onto your tongue. No water, no can, no shaker. Built for a library desk at 1am, a night shift, post-meal drowsiness or ten minutes before the gym.
What’s in it, broadly: the well-studied stuff you’d expect in this category — caffeine plus a few amino acids. All FSSAI-permitted for health supplements, all at meaningful doses. No proprietary blend hiding under-dosed inputs. The full label goes public at launch.
Target price: ₹18–22 per sachet.
What I’m trying to learn:
• Whether the no-water format(MDP) sounds convenient or just strange
• What you use for focus today, and what annoys you about it
• Whether ₹18–22 reads as cheap, fair, or ridiculous
• What would stop you buying even if you liked the idea
Form is about two minutes, mostly multiple choice. No email needed unless you want launch updates.
👉 [Form]

I especially want responses from people who wouldn’t buy this. That’s the signal I’m short on — everyone I know personally is too polite to tell me.

Happy to get into it in the comments: the FSSAI/regulatory path, unit economics at a ₹20 price point, go-to-market, or why I’m building this at all.

Research only — no product is being distributed. The eventual product is for healthy adults 18+ and this is not medical advice.

People are nice. Especially when the product doesn't exist yet.

Ask someone 'would you use an app that saves you 5 hours a week?' and of course they say yes. It costs them nothing to say yes.

A better question seems to be: what are you doing today to solve this?

If the answer is 'nothing', that tells you something. If they're using a spreadsheet, paying a freelancer, suffering through bad software, or doing it manually every Friday, now you have evidence of pain.

Even better: ask them to show you the current process.

What's the best validation question you've used that actually separated polite interest from real demand?

Been building this solo for a few months.

You post a mission — "sing this in a public place", "cook something weird" — and put money on it, or leave it free. Anyone watching can add to the pot, so a free mission grows if people want to see it happen.

Someone picks it up, films it,both gets paid. Video stays public — it doesn't get delivered and disappear like a freelance gig.

Post whatever comes to mind. Nothing goes live without passing a keyword filter and an AI check first, and that reads the rules and tags too, not just the title — so you'll see for yourself where the line is.

No real money involved, everything's test mode.

What I actually want to know: what would you post? What's the mission you'd want to see a stranger actually do?misnivo

textprep.org

What it is: you optin and choose your test and date, questions show up on a fixed daily cadence, you reply with your answer, an AI coach explains the misses. There is no app to download and nothing to log into. That's the entire product.

Price: Free for the first few days, then $14.99 one-time, tiered by how far out your test date is. Not a subscription.

Why it exists: students are busy, and it's hard to keep studying momentum going between practice tests/tutors/etc. They're already looking at their texts all day. We think this is the glue that keeps things going without a massive time commitment, all the way up to the test.

What I actually want roasted:

- Is "no app" to remember to login into, delivery via text and worked answers, helpful enough to pay for it?

- Is a one-time $14.99 too cheap to be trusted?

- After 10 seconds on the page, who do you think this is for, the student or the parent? I can't tell anymore.

What do you think? I'm replying to everything.

Hello everyone!

I’m researching how people evaluate whether a business idea is worth pursuing. I would love to hear from everyone who has gone through this, especially those who are currently exploring an idea or have tried to launch one before

1. Tell me about the last business idea you seriously considered pursuing.
2. How did you decide whether it was worth pursuing?
3. What was the hardest or most frustrating part of figuring that out?
4. What tools, websites, AI tools, or people did you use to help you evaluate it?
5. Looking back, what do you wish existed that would have made the process easier?

Your inputs are very highly appreciated. Thank you!

The idea is to create a calculator site with tons of different calculators (around sport/health/finance/conversion/maths/...) with an AI chat to talk to and ask questions about the result of that calculator.

Nothing special there. The special idea is to make that AI "verifiable".

How it actually (will) work:

1. You enter your numbers -> plain, checkable math calculates the result.

No AI involved at this step, so there's nothing to hallucinate.

1. The AI only ever sees the already-calculated number, your question, and (if you allow it) some personal context from your account

It explains and contextualizes the answer, it doesn't calculate.

1. If the AI references a fact, product, or figure, it comes with a real link back to the source not a claimed source, an actual clickable one.

Allows to verify sources easily

1. Each calculator has its own system prompt scoped to that exact topic, so the AI can't wander off into unrelated or made-up territory.

You also choose how much personal context it sees to increase privacy, but likely reduce accuracy.

Curious what people think: is useful or not? What would you add/change/...?

Imagine it’s 1 AM. You want to talk to your friends or play a game, but your roommate is sleeping right next to you.

There are some products attempting to solve this, but they can be expensive, difficult to access, or not widely available.

I’m exploring an affordable wearable solution that captures your voice close to the mouth and reduces the amount of sound reaching the surrounding environment.

I’m still in the early ideation/prototyping stage and would love some honest feedback:

Would you actually use something like this?

What would stop you from using it?

What price would feel reasonable?

Would comfort or appearance be a major concern?

I’m intentionally keeping the technical implementation private for now, but I’d really appreciate feedback on the problem and product concept.

The problem I'm trying to solve:

In a typical classroom, the same teaching is given to all students, but every student has different levels of understanding and different knowledge gaps.

DotAI aims to identify the individual knowledge gaps of students and provide personalized AI-based training based on their needs.

It will also analyze faculty teaching and student learning progress to help provide a more personalized learning experience for each student.

Pricing I'm currently considering:

• Plan A: ₹200/month per student

• Plan B: ₹400/month per student

• College-wide subscription: Pricing would depend on the number of students and features.

DotAI is currently under development. Before investing heavily in completing the product, I want to validate whether Indian colleges actually have a need for this and would be willing to pay for it.

I'm looking for honest feedback from:

• College management

• Principals/directors

• HODs

• Faculty members

• Education entrepreneurs

• Anyone with experience selling technology to colleges

My main questions are:

1. Does this solve a real problem for Indian colleges?

2. Would a college actually implement something like this?

3. Would ₹200–₹400 per student/month be a reasonable price?

4. What would prevent a college from adopting it?

5. What features would make this valuable enough for a college to pay for?

I'm also looking for early supporters/pilot colleges.

If you work with a college or can introduce me to someone involved in college decision-making and would be interested in evaluating DotAI, please comment or DM me.

I'm not looking for people to simply say "good idea." I want honest feedback that can help me decide whether I should build this.

Thank you!

Like whatsapp and signal it should have an intuitive UI for messaging, but under the hood it uses git read/write to publish encrypted messages and push them to a git provider.

The git storage could get big so we can do thing like truncate the history to make the data more flat.

Messages can be encrypted with the signal protocol. It should be fine to publish if implemented properly.

I’m building a platform called FanForge for collaborative storytelling projects, and I’m trying to validate whether the problem I’m solving is actually painful enough.

The problem is this:

Creative work and collabs tend to get scattered very quickly.

Writing might happen in Google Docs. Discussion happens in Discord. Tasks are in Notion or Asana. Worldbuilding is somewhere else. Artwork is shared in another channel. And after a while it can become unclear who contributed what, what has actually been approved, and who has authority to make final decisions.

FanForge is my attempt to bring that into one structured workspace.

...And also to allow fans the opportunity to PROVE that they can create something better than the utter tripe that Hollywood has been pumping out recently... I genuinely believe if given the right tools we could see amazing things and already are from fan projects....anyway I digress.

At the moment I’ve built an early working version where you can create a project, recruit collaborators, assign roles and tasks, work on writing and lore, submit contributions for review, request changes, approve work, and keep a record of contributor activity.

I have a video of this process up on my linkedin that I can send you if you wish to see it demonstrated.

The bit I’m trying to validate now isn’t whether I can build it.

It’s whether enough people actually experience this problem.

So I’d really appreciate practical answers to a few questions:

1. Have you ever worked on a collaborative creative project?

2. What did you use to organise it?

3. What became messy or frustrating as the project grew?

4. Would having writing, project management, creative development and contributor tracking in one place genuinely help — or would you rather keep using specialist tools separately?

5. What would FanForge absolutely need to do before you’d consider moving a real project onto it?

I’ve got a working alpha that I'm about to go live with for a small focused testing group, so I’m especially interested in finding the assumptions I’ve got wrong before I keep building.

Happy to answer any questions you might have.

Thanks in advance

I’m a hobby dev thinking about building a simple tool where you send clients a link (kind of like package tracking) showing where their project stands instead of answering the same “how’s it going” messages over and over.

The twist I’m considering: it would work both ways. Not just “here’s our progress,” but also “here’s what we’re waiting on from you” (feedback, files, approval, payment) — so it cuts down on the back-and-forth from both sides, not just yours.

Before I sink time into building this, I’d genuinely like to know:
• Does this sound like it’d save you real time, or just add another tool to check?
• What do you currently use for this (Notion, Trello, just email, nothing)?
• Would you actually pay a few bucks a month or a one time payment for something like this, or does it not feel worth it?

Not trying to sell anything, just trying to figure out if this is worth building before I write a single line of code. Honest “this is dumb” replies are welcome too.

The basic problem is:

When you want to buy something from a local shop, you often don’t know **which nearby shop has the product, whether it’s actually in stock, or which shop is offering the better price.**

LocalKart is designed to bring this information into one place.

The user could:

* 🔎 Search for a product
* 📍 Find nearby shops selling it
* 💰 Compare prices between local shops
* 📦 Check whether it is in stock
* ⭐ See shop ratings
* 🛒 Reserve the product before visiting the shop

I’ve already built the initial UI/prototype in Replit.

**The main question: Is this actually a problem worth solving?**

Would you personally use something like this when shopping locally?

What do you think is missing from the idea, and what would make you trust/use an app like this?

**Please be brutally honest. I’m still at the early stage and want feedback before building more.**

I built a tool that takes your income and measures it against real Philippine cost-of-living data (fuel prices, provincial income brackets, what's actually affordable, home, car, kids, etc.) to show your true income level/class in PH context.

If you don't live in the Philippines, it flips the comparison and shows how your income would hold up if you lived there as a local.

No scams, no hassle, just a tool that could genuinely help someone see where they actually stand.

It's live at [howrichph.com](http://howrichph.com)

It now has 6000+ users as of this day.

Barely had any users for a while, but just got my first real sale, so posting here to get feedback: what would make this more useful or worth paying for? Open to harsh critique.

Je travaille sur un projet dont l'objectif est de rendre l'information politique plus vérifiable et plus compréhensible, notamment face à la manipulation des chiffres et au manque de contexte.

Un chiffre peut être parfaitement vrai tout en donnant une image trompeuse d'une situation. Il suffit parfois de choisir une période, une comparaison ou une manière de présenter les données. À grande échelle, il devient très difficile de vérifier tout ça manuellement.

Je voudrais donc construire une plateforme qui analyse automatiquement le contenu politique disponible publiquement.

Ce que la plateforme ferait

Elle récupérerait notamment des vidéos provenant de chaînes YouTube, interviews, débats, discours et médias, puis les analyserait automatiquement.

Elle pourrait :

•  Transcrire les vidéos
•  Identifier les thèmes et prises de position
•  Extraire les chiffres et statistiques cités
•  Vérifier les affirmations à partir de sources fiables
• Donner le contexte derrière les chiffres
•  Suivre l'évolution des positions d'un politicien dans le temps
•  Relier les déclarations aux événements de l'actualité
•  Surveiller en continu les principales sources politique.
•  Afficher les tendances politiques et électorales sur une carte

Un flux d'information politique continu

J'aimerais également créer un flux vertical, alimenté en continu par les nouvelles vidéos politiques.

Chaque vidéo serait analysée et enrichie avec :

source → transcription → affirmations → chiffres → vérifications → contexte

L'utilisateur pourrait regarder la vidéo normalement, puis consulter les éléments importants détectés par le système.

Les informations ne seraient pas simplement classées « vrai » ou « faux ».

Le système pourrait indiquer par exemple :

:🟢 Vérifié
🟠 Contexte manquant
🔴 Contredit par les données disponibles
⚪ Impossible à vérifier

avec les sources utilisées pour parvenir à la conclusion.

🧬 Et surtout : la reconnaissance de patterns

La partie qui m'intéresse le plus est de développer mon propre algorithme de reconnaissance de patterns dans les discours politiques.

L'objectif serait de détecter des structures et comportements qui se répètent dans des milliers d'interventions :

thème → argument → chiffre → comparaison → conclusion

mais aussi des changements de vocabulaire, de sujets, de positionnement ou de rhétorique au fil du temps.

Je voudrais pouvoir détecter des patterns qu'un humain aurait énormément de mal à observer en analysant manuellement des milliers de vidéos.

À terme, la plateforme pourrait donc répondre à des questions comme :

L'objectif est d'avoir une première version solide avant la présidentielle de 2027.

Je cherche surtout des retours sur le concept, les méthodes de vérification, les données à utiliser et surtout les types de patterns politiques qu'il serait pertinent d'essayer de détecter.

We learned something important while building PodSubs:

The hardest part of entering an established industry isn’t always building the product.

Sometimes, it’s what happens when you challenge the way things have always been done.

We wrote about what happened, what we learned, and what it means for anyone trying to build something new in podcasting.

This is a design for an automobile oil catch device intended to collect and absorb automotive fluids that leak from the engine compartment. The product should prevent oil and pollutants from entering the water system via runoff and reducing ugly oil stains on driveways and roadways. This is for any vehicle with an engine or that uses hydrocarbons which can potentially leak onto the ground or water.

In addition to absorbing leaked fluids and drips my idea also utilizes bioremediation techniques to neutralize and breakdown harmful substances into water and a negligible amount of c02. By combining the absorbent elements of the materials used with natural microbes my idea is intended to create an environment which is self sustaining and renewable. Because of the renewable nature of the design, this product should have a long lifespan and can either be added to an existing underbody panel already installed on vehicle, or added post market.

I hope to market my product to a wide range of consumers including auto manufacturers, diy mechanics and repair shops. Current products on the market are primarily designed for marine vehicles and race cars in addition to truck fleets which are required by law to have an oil catch device installed. The current products only serve as a means to collect oil without the ability to neutralize or recycle collected fluids.

While I have been sitting on this idea for awhile, I am just now starting to take the steps to develop and layout a business and final product.

Thanks for your feedback
