I don't know about online tools, but it should be the opposite when actually using it, as by default Meshtastic is much more chatty (and wasteful) than Meshcore.
Do people communicate to distribute prohibited anti-government propaganda or is it a network of people who otherwise be too shy to talk to each other by other means?
What is the use case?
It's primarily just an experimental system. Demonstrating that fixed infrastructure isn't actually necessary to communicate.
Beyond that, it's a mixture of HAM radio for communicating with people outside of your immediate circle, and disaster prep.
The best realistic scenario I can see for using it is after a sever weather event like hurricane, tornado, tsunami, etc. that takes out significant comms equipment. Having an ad-hoc network pop up using battery powered nodes able to setup a secure comms channel to organise aid deliveries would be a powerful tool. But existing infrastructure is resilient enough that it's not actually necessary in modern times.
Beyond that, it's probably more of an IoT type thing. Setup a bunch of nodes across a significant area of land, run machinery, sensors, etc. remotely via a self-healing mesh network.
Go somewhere properly remote such as the high north. There is no cell network outside of town. And the satellite coverage is spotty at best. Say you need to go look for someone. Meshtastic relays can be up and working in minutes. A chain of rescuers can spread out along a path, and remain talking to each other, as fast as they can move. Sure, radios can do this too, but long range voice radio require serious power and are still largely line-of-sight. Radio relays are an entirely other expensive thing.
Think also of remote camps (logging/planting/fishing/climbing etc). Toss a lora relay on every vehicle and every work party can talk via the app installed on their normal phones. Use GPS-enabled devices and you can passively keep track of every vehicle. Need to operate two valleys over? As the first crew deploys out they can plop down relays at key points. Years ago I setup something like this using wifi relays. It was hell. It never worked right. The range and lower power demands of lora would have been infinitely easier.
Something that can also use devices we already have seems like a better solution. I'm surprised BitChat has not seen more popularity. Something that combined that + a dedicated hardware mesh transmitter (for longer range when needed) and allowed adhocactual network use between devices would be pretty damn cool.
Also arent LoRA systems mostly still line of sight?
They already have it because they ready HN! Only somewhat fascitious... A few motivated individuals can provide connectivity to thousands. There's probably a few such folks in your city already!

This is exactly how these systems tend to work in practice. Just connect your phone via Bluetooth then use the Meshtastic app. The app can function on it's own to send messages to other phones without cell service, you just won't get the range.
Not to say they don't fill a niche, but bandwidth and range limit it's viability to small operations; even an optimal network cant handle more than a few hundred tweets per hour.
I've done a number of projects with commercial radios operating in the 902-928MHz unlicensed band and typically we target 1-10 mi (roughly 1-20km). Elevated antennas with enough gain to get you to the legal limit (4W EIRP) can get you a heck of a lot of range, even without line of sight.
With line of sight, communication to the horizon is possible.
If you're talking about the EU 869 MHz unlicensed band used by LoraWAN, thats quite a bit different and I'm less familiar.
For instance, sprinkling a bunch of nodes + sensors in hostile territory should allow for gathering intelligence, guiding drones, setting of fuses...
With the obvious solution of putting mesh nodes on the drones, foregoing the scattering part.
For everyone else, IoT is already there. And good old paying people to do things (the supply of dumb people never gets depleted).
Five mins from our house suddenly cell service from all the providers gets very spotty. If you live near the top of a hill facing the right direction, you can maybe jury rig a cellular antenna on a pole. There is legacy POTS phone service via 60 year-old copper but few use it because it's only ISDN barely faster than dial-up and >$100/mo. Otherwise, there was no option for reliable residential phone/data/text service until Starlink became available in our area a couple years ago.
So everyone in our entire area has 2M radios to communicate in emergencies because in four years we've had two fires come close enough to close our roads, been snowed in twice (without power) and a small bridge got damaged in flooding blocking vehicle access in and out for four days. We can't even see any of our neighbor's houses from our property yet several times a year we need to get extremely local information from, and coordinate with, people we'd have to hike to visit. And it's usually because something is happening which takes out local power and/or road access. But the old 2M radios have to be monitored in a real-time which feels really antiquated. So, to me, inexpensive LoRa that could enable store-and-forward messaging and conditional unattended alerts suddenly sounds very useful.
A lot of people use it just to chat with friends and family in a fun way.
Of course the preppers and privacy evangelists see it as a means to get ready for living in a hostile environment. Being fair to them, things don't look awesome in the US.
I bet a few criminals use it, but it's still very niche.
Nevertheless IMO the mentioned demographics/use-cases want something turnkey ready, ~single button, and currently LORA based stuff is not like that, and is clumsier and needs a certain level of... tinkerer mindset, compared to a commercial license free radio system (which might have been set up with a minimal effort), where learning curve is basically volume knob and PTT button.
I have handed out simple FM radios for total tech-illiterate people (mothers, children, elderly physical workers) in an outdoor event with 0 cell coverage, and comms worked perfectly over the dozen square kilometer area. Biggest incident was a lost radio handset.
These people should not be making a short range text solution, they should be building a low bandwidth internet extension with gateways to the real internet. Most of the information content of the internet can readily fit over 56kb lines once you strip out all the fluff. And in an emergency where you need or want a decentralized mesh network, that's more important that being able to text, who exactly?
Otherwise, you buy a couple, set them up, spend a week or two sending very slow and unreliably forwarded messages that mostly amount to "hi! i have an ACME 32ABC radio! What do you have?", and then put it in a drawer or sell it on.
Just like ham radio, really.
More practically, I'm going to try it out while camping this summer. In areas with low or no cell coverage, my phone is useless or dies quickly. Throw a repeater in a tree, and hand your friends nodes.
Sometimes you discuss new Meshtastic gear or setting up a router together.
Of course if it ever becomes popular, that will quickly change. But for now it is like early IRC.
Advertising services
But only if use of the network becomes popular
(Generally no one thought this would be the eventual use case for the internet)
Something like this might work?

Then everyone does.
Any bandwidth is better than zero.
95% of it is people just doing ping? Pong! In chat.
The cheapest devices are like $10. Order one and have a go.
Would be great if it also ran some type of Topo mapping software!
To give more info here, it uses Heltec Wireless Paper, which is a self-contained unit and just needs a battery added.
I worked R&D on LoRa project a few years ago. Their use case was a long-range emergency communication system for workers in remote areas(no wifi, lte or LEO at that time). Now I see a bunch of applications in this field that aren't what you describe. :)
Gov/DoD/SpecOps use it to maintain radio connectivity with things like the Android Tactical Assault Kit (ATAK).
People are very enamored with what you could theoretically do with it, but they never actually do any of it. It's a hardware fetish, it's all about building boxes with solar panels and seeing how many nodes you can light up on the map. Reminds me of another ham radio thing I never got into, "contesting".
But also you don’t build these things when you need them (it will be too late), you need to build them before you need them.
The entire thing would fall over in any kind of scenario where you needed to rely on this janky mesh network as a primary means of communications.
It can be fun/useful for very out of the way things where you have a handful of people out camping, or other off-grid situations. But frankly even in those cases there are far better/established ways to keep in sync if you need to (eg: FRS).
This stuff is mostly a solution looking for a problem.
