Built this because every time I needed to raise a GST invoice, check an HSN code, or work out professional tax for a different state, I ended up on five different sites half of them paywalled after the third use.

IndianBusinessTools (indianbusinesstools.com) is a free set of tools for that stuff:

Sixteen predictions, none of them graded. The first verdict is 28 February 2027, and until then my score is nothing at all.

That's the design. Every forecast carries three things fixed at the moment it's sealed: a probability, the date it gets judged, and a written condition that would settle it against me. None of the three can be edited afterwards. Pundits are never wrong because they never commit to all three they just get quoted less.

Underneath it is a published rule over 36 named strands, stepped every six hours off 8 live wires. No language model anywhere in the forecasting path. Every constant is public, including the 24 couplings between strands each one carries a written reason and a historical precedent. Escalation feeds debt strain at +0.04, on 1914, 1940 and 2022.

The part I'd defend hardest: the alert log keeps the alerts that came to nothing. Three opened, four cleared, all seven still on the page. A log that kept only the dramatic entries would be an advertisement, not a record.

Hey Product Hunt! I'm Bahaa, maker of Stillora.

Stillora is an MP4 video maker for iPhone, iPad and Mac that combines images, video clips and audio into a single MP4 file, without a complicated editing timeline. Pick your media, choose a format, export. Your files stay on your device.

Why I built it

YouTube, Instagram, TikTok and LinkedIn don't accept audio-only files. Every time I wanted to share a voice note, a song or a podcast clip, I had to open a full video editor just to put one image behind a sound file. Stillora removes those steps: image + audio in, MP4 out.

My ring tracks sleep and recovery. My workout app tracks training. Each gives me charts and scores, but I m still the one trying to connect the dots.

Sometimes it feels like every app is another beautifully designed spreadsheet: useful for seeing what happened, less useful for deciding what to do next.

Hey Product Hunt!

I'm launching Noir Prompt on April 21st and wanted to give a heads-up to anyone who's been following along.

What is it?

Hey Product Hunt
I m building Civil All in One Calculator, a mobile app for civil engineers, construction professionals, and engineering students.

I started working on it after noticing how many routine engineering calculations are still spread across spreadsheets, websites, separate apps, and manual formulas.

The app has grown to include 23+ calculators and tools covering areas such as concrete quantities, steel/rebar, structural calculations, surveying, construction calculations, and unit conversion.

While building it, one challenge I ve run into is deciding what is genuinely useful to engineers versus simply adding more calculators to increase the feature count.

We built DealGPT when we realised chats dont make money deals do.
DealGPT allows you to research with AI, connect with verified people, and deploy capital in a single interface.

We built Dvoider because every founder we knew was stuck between two bad options: sit on their idea alone out of fear it ll get stolen, or share it and lose control of it.

Dvoider validates your idea across 6 dimensions with AI scoring, timestamps and hashes it on-chain the moment you save it, and matches you with collaborators who fit the roles you re missing all without exposing your full idea until you choose to share it directly.

Hey Makers!

Building a startup entirely alone is brutal. From marketing to coding, wearing every hat usually leads straight to burnout.

That s exactly why we created Startives. It s a platform designed specifically for tech entrepreneurs to:

1. Match with verified, like-minded co-founders.

2. Validate startup ideas before spending months coding.

3. Build complete, balanced dream teams.
