RHYMERS Inc.Vertical AI · Tokyo · 2026

Different words,one rhythm.Separate products, moving to a single rhythm.

In a country short of hands, service can’t afford to slip. Conversation (Tarara) and documents (Travelz Pro) — the two jobs that keep the front line moving, handed to AI. A bilingual, vertical AI SaaS, built for Japan.

SCROLL
Mission — what we believe

Erase “not enoughhands” from the front line.

MANIFESTO / 3
01
Bilingual by design

Every product is designed bilingual — Japanese and English. In an era of 42.68 million inbound visitors, the language barrier isn’t a feature we bolt on later; it’s the first assumption. UI, AI responses, documents, even legal pages: two languages, both native.

02
Deep in the workflow

A general AI tool starts with a question: how do I use this? We’re different. Itinerary-building, phone reception — we take on the job itself. From the day it goes live, the front line has hands to spare.

03
Many products, one mind

Conversation and documents — we replace the two great front-line jobs with AI, then layer more products onto the same customer. Like different words falling into rhyme, separate products move to a single rhythm. That’s Rhymers.

Macro — the landscape

Two structural tailwinds,blowing at once.

Demand climbs, the workforce shrinks. Only one thing can close that gap: software. Rhymers puts a purpose-built AI on each of two front lines — travel arrangement, and the phone at the shop.

Tarara

Your shop’s phone?AI picks up.

AI phone reception for restaurants, inns and shops. Around the clock, AI answers in a natural voice, writes bookings straight to Google Calendar, and records, summarizes and notifies on every call. Underneath sits a conversation platform with a public API and SDK — partners build their own products on top.

P1

Public API, SDK & signed webhooks

A frozen /platform/v1 API plus a TypeScript SDK. Partners build their own branded reception AI — no domestic rival offers a comparable open foundation.

P2

Every call, fully replayable from an event log

Quality checks, audits and improvement, done scientifically. OpenAI, ElevenLabs and others swap in via adapters — a provider-agnostic design.

P3

Same engine, the next app

Concierge, outbound, reminders — engine and API unchanged, apps stacked on top to grow revenue per customer.

Synergy — why one company

Conversation and documents.Two sides of one customer’s work.

WHY ONE COMPANY
01

Travelz Pro is Tarara’s official reference integration

A working integration built entirely on Tarara’s public SDK already exists. Phone booking → deal & itinerary is technically proven.

02

The cross-sell path is natural

Tarara answers the agency’s phone; those bookings and inquiries flow into Travelz Pro’s deal pipeline. One customer, two products.

03

Shared tech and know-how

Bilingual AI, Stripe billing and credit design, and a hard-won playbook for selling to Japan’s small service businesses — all shared across both.

Like different words falling into rhyme,
separate products move to a single rhythm.

By the numbers — what we’ve built

A small team.Two production-grade products.
