Plinthos.app VS Diffyn

Plinthos.app's answer

It's built around the room, not the apartment. Other landlord tools assume one apartment let to one tenant on one lease. Plinthos handles a single flat with several rooms, multiple tenants, and bills that get split every month. The tenant side is free and tenants join with one link, so the product spreads on its own.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Plinthos.app's answer

Most competitors are single-sided landlord tools for whole-flat leases. Plinthos covers the messy part they skip: per-room pricing, multiple tenants per flat, automatic bill splitting (equal, by days or by square meters), deposits with a guided check-out, and built-in chat. Both sides get an app, the tenant one is free forever, and it works across countries, currencies and five languages on iOS, Android and web.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Plinthos.app's answer

React Native and Expo for the iOS and Android apps, a React web app, and Supabase (Postgres, auth, storage, edge functions) for the backend. RevenueCat handles subscriptions across stores, Paddle handles web billing, Cloudflare hosts the web app, Sentry covers error tracking, and bill scanning uses Google Gemini.

Diffyn's answer:

React, Next.js, POSTGRESQL

Plinthos.app's answer

Small, independent landlords with 1-3 properties who rent out individual rooms, usually to students and young workers in shared flats or co-living. Their tenants are the second audience and use Plinthos for free.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

Plinthos.app's answer

It started from watching small landlords run room rentals on a WhatsApp group, a spreadsheet and the calculator app, losing an evening every month figuring out who paid rent and who still owed for the gas bill. Every tool out there was made for renting a whole apartment to one tenant. Plinthos was built to fit how rooms are actually rented: several tenants, split bills, deposits, all in one place.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
