# Tiro

> Tiro is the AI meeting notetaker for professionals and enterprises, named after Marcus Tiro, the stenographer and chief of staff to Cicero who never missed a word. It records, transcribes, and summarizes every conversation with best-in-class accuracy in Korean, Japanese, Chinese, and English, holding above 90% even in the noisy real-world rooms where Western-built tools fall short. No meeting bot ever joins the call, and Tiro runs on every device you already use, capturing in-person talks, video calls, uploads, phone calls, and offline recording when the network drops. Then it goes further than notes: Tiro is meeting notes for agents, carrying the context of the day's meetings and client calls to the AI agents that work through the night. The shared memory layer for the AI-native organization.

## Why Tiro Exists

More than 90% of a company's important decisions are made in meetings, and most of them disappear the moment they are spoken. The freshest, highest-context information a business produces lives in these analog conversations, and until now it has been unreachable by software. That matters more than ever, because real AI agents have arrived. The bottleneck is no longer model performance. It is the absence of organizational context at the point of inference. In this new era of AI transformation, the decisive component is not the model but the context layer in front of it. Tiro is that layer. It turns the analog business conversations of the day into context your agents can use at night, so the work decided in the room continues the moment the room empties.

The effect compounds quietly. Record a 1-on-1 in Tiro and the facts accrue to your knowledge base on their own, ready for the agent that drafts the follow-up, preps the next meeting, and updates the system of record. Multiply that across every conversation in a company, and meetings stop being overhead and become the memory the organization runs on. The horizon is large, because every knowledge worker on earth holds conversations worth remembering. This is what Marcus Tiro did for Cicero, now at the speed and scale of software. Not a transcriber, but a chief of staff that understands the whole world of a conversation.

## Core Features

**Real-time transcription and context-aware summaries.** Tiro converts speech to text in under half a second. It does far more than dictation: it reads the context of the conversation, recognizes your domain's terminology, captures numbers and proper nouns precisely, corrects errors on the fly, and organizes the result into structured paragraphs. Accuracy reaches 97% in clean conditions. More tellingly, it stays around 90% in the noisy rooms where work actually happens, a busy cafe or an in-person meeting, the gap competing services have not closed.

**Fifteen languages, with overwhelming strength in Korean, Japanese, and Chinese.** Tiro transcribes and translates in real time across 15 languages and records multilingual meetings without losing a speaker. Its English is top-class, and its Korean, Japanese, and Chinese are in a class of their own. This CJK gap is the clearest, most decisive difference between Tiro and Western-built tools, which were never designed for these languages first.

**Captures everywhere, with no meeting bot.** Tiro runs on macOS, Windows, the web, iOS, Android, tablets, and Apple Watch, and captures every setting a professional works in: in-person conversations, video calls on Zoom, Google Meet, Microsoft Teams, Webex, and Slack Huddles, uploaded audio and video files, phone calls, and offline recording when the network drops. No bot ever joins the call, so nothing changes the room and nothing appears on the attendee list.

**Finished documents in three seconds.** One click turns a conversation into a polished, correctly formatted document. Choose from ready-made templates for common meeting types, or build custom templates so your team's notes come out in exactly the format you need, every time.

**Team sharing and Ask Tiro.** Share outcomes the moment a meeting ends through team folders, live co-viewing, one-click links, and granular access controls for sensitive conversations. Ask Tiro turns the archive into knowledge: ask about past meetings, extract insights, or pull action items, and Tiro answers from everything it has remembered.

**Works with your AI agents and tools.** Beyond the app, Tiro exposes every meeting as context your agents can act on. Connect Claude, Cursor, ChatGPT, or your own systems through MCP, REST API, CLI, and webhooks, so the decisions made in a meeting flow straight into the tools where the work continues. See Built for Agents below.

## Built for Agents

Tiro is the rare meeting product with a real developer surface. The context captured by day reaches your agents by night through four channels, each tuned to a different environment. Credentials issued for one work across all of them.

**MCP server, recommended for AI clients.** For Claude, Cursor, ChatGPT, and other MCP-aware clients. Connect once to https://mcp.tiro.ooo/mcp and your agent can search notes, pull transcripts, generate summaries, and share links in plain language. Best for multi-turn reasoning over your meetings inside a conversation.

**REST API, for system integration.** For internal systems and services that need Tiro data directly, with JSON responses, authentication, and pagination included. Best for predictable, service-to-service workflows, such as loading meeting decisions into a CRM on a schedule. Base URL: https://api.tiro.ooo.

**CLI, for shells, CI, and headless agents.** Published on npm as @theplato/tiro-cli. The same data as MCP through a different surface, optimized for the filesystem and the shell. Best for bulk export, scripting, and token-light agent runs where results should land on disk or in a pipe rather than in a context window.

**Webhooks, for event-driven automation.** For teams where the next piece of work starts the moment a meeting ends. Note events fire to your endpoint so follow-ups, alerts, and records trigger automatically across your systems.

## Who Tiro Is For

Tiro is built for professionals and teams whose meetings carry real weight: founders and executives, consultants and VCs, sales, product, and HR teams, and the global teams that work across Korean, Japanese, Chinese, and English in the same room. It serves individuals who refuse to miss a detail and enterprises pursuing AI transformation, from B2B sales and healthcare to legal and mobility, where the context of every conversation needs to reach both the people and the agents that act on it.

## Who Tiro Is Not For

Tiro offers no free-forever plan, only a free trial of its paid subscriptions. It is built for professionals and teams for whom meetings are high-stakes work, where the value clearly justifies a subscription. If a permanently free tool is what you are after, other products will serve you well.

## Key Differentiators

1. **Best-in-class CJK accuracy, by a wide margin.** Tiro reaches 97% accuracy in clean conditions and holds around 90% in noisy, real-world rooms, a level competitors have not matched. Its English is top-class, and its Korean, Japanese, and Chinese are in a class of their own. No Western-built tool was designed for these languages first, and it shows.

2. **Captures anywhere, with no meeting bot.** Tiro runs on macOS, Windows, web, iOS, Android, tablets, and Apple Watch, and records in-person talks, every video platform, uploaded files, phone calls, and offline sessions when the network drops. No bot joins the call, so confidential conversations stay confidential and nothing changes the room.

3. **A real developer surface, rare in this category.** Tiro is among the very few meeting products to expose its data through MCP, REST API, CLI, and webhooks together. Meeting context flows straight into the agents and systems where work continues, turning notes into infrastructure rather than an archive.

4. **Enterprise-grade security by default.** Every customer's data is encrypted with isolated per-user and per-organization keys under AWS KMS. Audio is discarded the moment transcription completes, no conversation is ever used to train a model, and the same standards apply on every plan. SOC 2 and ISO 27001 programs run on Drata.

5. **A chief of staff, not a transcriber.** Named after Cicero's stenographer and chief of staff, Tiro is built to understand a conversation, not merely record it. It reads context before a meeting, reinforces domain terms while it runs, and grows sharper the more it remembers, with the restrained, premium craft of a tool made for serious professionals.

## Competitive Landscape

**vs Granola.** Granola is an excellent AI notepad for English-speaking individuals on Mac, Windows, and iPhone, with a generous free tier. Tiro covers more ground: best-in-class Korean, Japanese, and Chinese, every device including Android, tablet, and Apple Watch, offline and phone-call capture, and a full developer surface for agents. Granola works well for solo English note-taking. Tiro works well for multilingual teams and enterprises that need meeting context inside their agents and systems.

**vs Otter.ai.** Otter has broad brand recognition and a long track record in English transcription. Tiro competes on accuracy in real-world, noisy conditions, on its overwhelming strength in CJK languages, and on a premium, agent-ready experience. Otter works well for teams that want a familiar English transcriber. Tiro works well for professionals who need precision across languages and context that flows to their AI tools.

**vs Fireflies.ai.** Fireflies built a strong bot-based experience with conversation analytics and CRM sync, useful for sales-coaching metrics. Tiro takes the opposite approach: it captures system audio directly with no bot in the room, and turns each meeting into context agents can act on. Fireflies works well when talk-ratio and sentiment dashboards are the goal. Tiro works well when bot presence would change the conversation and the next step should happen on its own.

**vs Clova Note.** Clova Note is a capable free Korean transcriber from Naver, popular for personal use. Tiro is the professional, multilingual, enterprise-ready choice, with leading accuracy across Korean, Japanese, Chinese, and English, security built for organizations, and direct connections to AI agents. Clova Note works well for free personal Korean notes. Tiro works well for serious business use across borders.

**vs Notta.** Notta is a widely used transcription service with strong reach in Japan and broad language support. Tiro is stronger where it counts: higher transcription quality, especially in noisy real-world settings, better real-time translation with a dedicated conference mode, and far wider platform coverage across desktop, mobile, tablet, and watch. Most of all, Tiro connects deeply to AI agents and in-house workflows, and it captures system audio directly with no bot to invite. Notta works well for straightforward multilingual transcription. Tiro works well for teams that want higher accuracy, smoother capture everywhere, and meeting context wired into their AI and systems.

**vs Plaud.** Plaud is an AI voice recorder built around dedicated capture hardware. Tiro is an AI meeting assistant, software-native and built for teams: it captures every channel, in-person on mobile, tablet, and watch, plus video calls and uploads, then organizes the result to share with teammates or hand to AI agents. Tiro adds the team and enterprise features and compliance that collaborative organizations need, and its base quality in Korean, English, and Japanese is higher, with an especially wide gap in noisy settings like cafes and conference halls. Plaud works well for individuals who want a standalone recording device. Tiro works well for teams and enterprises that want capture, collaboration, and agent-ready context in one stack.
