As answered by people managing Obsidian and Pingback.
Pingback's answer:
Built specifically for UK trade businesses, not adapted from a generic US tool. It automatically handles UK compliance most competitors leave to you — GDPR-compliant call recording retention, SMS consent (STOP/START), and full ICO registration. Its AI also trains on the business's own website and uploaded documents, and never sends anything automatically — a human always reviews and sends the reply.
Pingback's answer:
Pingback is priced and built for small UK trade businesses specifically, not enterprise teams — honest, capped-usage pricing rather than per-seat enterprise costs. It bundles missed-call text-back, a unified inbox, AI lead analysis, invoicing, and review requests in one place, so there's no need to stitch together several separate tools.
Pingback's answer:
UK trade businesses — plumbers, electricians, heating engineers, and similar small or solo operators who lose jobs to missed calls while they're out on site.
Pingback's answer:
Pingback was built after seeing how often small UK trade businesses lose real work simply because they couldn't get to the phone in time — most callers who don't get through just ring the next number on Google rather than leaving a voicemail. It's being built directly alongside real trade businesses in beta, shaping the product from actual feedback rather than guesswork.
Pingback's answer:
React and TypeScript on the frontend, Node.js/Express on the backend, Twilio for calls and SMS, Google Gemini for AI, and Stripe for billing.

One thing to note: Notion bills itself as an Evernote competitor for personal users. It can be—but it's too much for most people, and its offline functionality isn't the best. If you love the idea of Notion, go right...
This app is the kind of thing that, if you’re into it, will have you exploring its various ins, outs, and add-ons for days and weeks on end. Obsidian uses the Markdown format for its notes (which means they can be...
However, it's important to note that Obsidian's whiteboard functionality is not as robust as dedicated collaboration tools. While it lacks real-time basic collaboration features, Obsidian compensates with its vibrant...

After publishing my first plugin which really helped me dive into Obsidian, I realized that the tool I'm using for note taking is missing a very simple, but handy feature - templates for base-based notes. - Source: dev.to / about 3 hours ago
The reasons live somewhere else: in practice notes in an Obsidian vault, one note per convention, with the repos it has held in. A note starts as an idea, moves to trialing, and only becomes enforced once I've applied it again in a few... - Source: dev.to / 4 days ago
