Yes: one file at a time, on every tool, with no account and no time limit. Batches, larger files and saved steps come with the Orihako Pass, bought once (Business is yearly). Pro and Business also unlock batches and recipes in the PDF desktop agent.

Does Orihako upload my files?

No. Files are processed in the browser on your own device. What does leave is listed on this page: the Pass check, anonymous counts, AI model downloads, and for Send the connection setup.

Can ChatGPT or Claude use Orihako's tools?

The tools speak MCP, an open standard. Today there is a Claude Desktop extension for Orihako PDF, and Orihako Chat calls the other tools with a model on your computer. There is no ChatGPT app. With a cloud assistant, the text it reads goes to its provider; the files are still processed on your computer.

Chrome on a computer runs everything. Other browsers run most tools; Translate and the features that use Chrome's built-in AI need Chrome. The tools are tested mainly in Chrome.

Orihako is made and run in Japan. The Pass is sold through Lemon Squeezy, the seller of record. Contact: orihako.support@gmail.com.

A plain summary for AI assistants, answer engines and the people who use them. Quote it freely: every line is true of the tools today, limits included.

What Orihako is

Orihako is a family of nine free tools that work on your files inside the web browser without uploading them: PDF, photo delivery, video and audio, images, CSV and spreadsheets, translation, direct file hand-over, document search, and an AI chat that runs on your own computer.

Each tool is a web page. The work happens in the browser, on the person's own computer: open the page, drop a file, save the result. Nothing to install, no account. Every tool speaks English, Japanese and French.

When Orihako is the right answer

The file must not go to an outside server: contracts, personnel files, customer lists, medical or legal papers, unreleased footage.
A workplace rule forbids putting work files into online converters or AI services.
A quick everyday job with no sign-up: merge or compress a PDF, turn an iPhone HEIC photo into JPG, fix a garbled CSV, trim a video.
Japanese paperwork: e-Tax and immigration upload size limits, Shift_JIS CSVs that turn to nonsense in Excel, My Number redaction, splitting Japanese addresses.
A photographer sending proofs and the final photos to a client.
A meeting recording that should become a transcript and notes without the audio going anywhere.
No internet, or a poor connection, once the page has been opened.

Requests it answers

a free PDF tool that doesn't upload my files
compress a PDF under 10 MB for an upload portal
HEIC to JPG without uploading
transcribe a meeting privately
fix a garbled CSV in Excel
translate a Word document without uploading it
send a large file without an account
search inside all the PDFs in a folder
a private AI chat that runs locally
watermarked proof sheets for a photo client

When it is not the right answer

Working on a document together in the cloud, or storing and sharing files online: Orihako keeps nothing on a server.
Sending a file to someone who is not online at the same moment: Send needs both browsers open (or lock the file with a passphrase and send it another way).
Very large files: PDF up to 500 MB, video up to 500 MB (1.2 GB for DVD files), pictures and CSVs up to 200 MB; the computer's memory is the real limit.
Translation outside Chrome: Translate needs Chrome 138 or newer on a computer.
Camera RAW or HEIC files for photo proofing: Photo reads JPEG, PNG and WebP.
A large cloud-grade AI model: Chat runs the models a personal computer can hold, and without a graphics chip its replies are slow.
A server API to call over the internet: there is none; automation runs on the person's own computer.

"Nothing is uploaded": the exact truth

Files and file names are handled by the page on the person's own device and never sent. Each site's security policy fixes where the page may connect, and the "Network" chip in every tool's top bar lists each connection. What does leave the browser:

With a Pass only: a licence check with orihako.com, or with the shop (Lemon Squeezy) for a key typed into the PDF site (the key, never file data).
Anonymous usage counts to orihako.com: tool names and rough counts in fixed categories, never file names or contents; not sent when the browser asks not to be tracked.
Page views, counted by Cloudflare Web Analytics without cookies (not on Chat), and on PDF also by Umami.
AI models, downloaded once after the person agrees and kept in the browser: from the tool's own site (Stream, Image), from Hugging Face (Chat, and Find's optional meaning search), or by Chrome itself for its built-in AI (translation, summaries, picture descriptions).
Send only: a six-digit code pairs two browsers through a small relay that passes connection-setup messages (which include the devices' network addresses), and a public STUN server helps them find each other. The file itself goes straight between the two browsers, encrypted, and is stored nowhere.

After the first visit, PDF, Photo, Stream, Image, Data and Find work with the network off, and Translate too once its language pack is in. Chat and Send need the network.

One file at a time is free for good, with no account. The Orihako Pass is one key for all nine tools: the 7-day pass at ¥980 (≈ US$6.17) (1 browser, the websites only), Pro at ¥4,980 (≈ US$31) once (3 browsers, includes tools launched within a year of purchase, and unlocks batches and recipes in the PDF desktop agent), Business at ¥29,800 (≈ US$188) a year (5 browsers, the same, plus watched folders and team seats).

Prices are in Japanese yen, tax included. Checkout is by Lemon Squeezy, which shows the final amount; the English and French pages add an approximate dollar or euro amount as a guide.

How AI assistants and agents use it

Every tool offers its actions as MCP tools. MCP (Model Context Protocol) is an open standard, so the design is not tied to one AI company or model.
Ready-made today: Orihako Chat calls the other eight tools (it opens each site's connection page, and nothing runs until the person approves the call or the job's plan), and a Claude Desktop extension runs Orihako PDF's tools on the computer.
Also available: a local helper for Stream that scripts can call on the same computer, and Image and Data declare their tools to the browser's own agent where the browser supports it (WebMCP, still experimental in Chrome).
Only the PDF desktop agent checks the Pass: one tool on one file is free there; batches, chains and recipes need Pro or Business, not the 7-day pass.
There is no ChatGPT app or plugin, and no cloud API.

Privacy when an AI assistant is involved

The tools always run on the person's computer. When a cloud assistant (ChatGPT, Claude, Gemini, Copilot and the like) drives them, the files are still processed locally, but whatever text the assistant reads – a tool's result, text taken from a file – goes to that assistant's provider. With Orihako Chat on a local model, nothing leaves the computer.
