Orihako for AI assistants and agents

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.

For this problem, this flow

Jobs that online tools usually do only after an upload, and the Orihako page for each: what it does, where it falls short, and which tool takes the result next. On every page the file is never uploaded to a server.

  • Transcribe a meeting recording without uploading itOrihako Stream turns the recording into text, SRT and VTT in the browser, with a speech model it downloads once (67 to 513 MB); free up to 30 minutes per file, longer with a Pass. Speaker labels are an AI draft to check, Japanese is read best by the larger model, and it is tested in Chrome on a computer. Next: Chat's meeting job drafts decisions and TODOs on this computer.The page · Orihako Stream
  • Translate a Word document, layout kept, without uploading itOrihako Translate rebuilds the .docx with its headings, lists and tables in place, using Chrome's built-in translator on the computer; free up to 5,000 characters per file (the rest stays in the original language, marked). Only Chrome 138 or newer on a computer; Chrome fetches a language pack from Google once per pair; a bold word inside a sentence takes the sentence's first style. PowerPoint, Excel and SRT subtitles go the same way.The page · Orihako Translate
  • Remove a photo's background without uploading itOrihako Image cuts out a person, a product or a pet in the browser (a model of 6.6 MB, 83 MB for objects, downloaded once) and saves a see-through PNG or sets it on white; free up to 25 megapixels, one picture at a time. Thin parts such as hair and clear glass are missed; without a graphics chip the object cut-out takes minutes. Next: compress to a target size, or make an ID photo, on the same site.The page · Orihako Image
  • Two PDF pages on one sheet, to print less paperOrihako PDF lays 2, 4, 9 or 16 pages on each A4, A3 or Letter sheet, or folds a booklet, as a PDF to print or send; free one file at a time. The pages shrink to fit, so small print may be hard to read on paper. A print dialog's own 2-per-sheet setting does the same for one print; this keeps a file.The page · Orihako PDF
  • Invoices named from their contents, listed in a table, keptOrihako PDF reads the date, issuer and amount of each invoice PDF (OCR for scans), names the files by a pattern you choose and saves them as a ZIP with a CSV index; many invoices at once are free, and the PDFs themselves are not changed. A value it could not read is left for you to type into the table before the name is right. Next: Orihako Data matches the CSV with the bank's CSV or totals it.The page · Orihako PDF
  • Hide personal data in a list or a PDF before sharing itOrihako Data masks phone numbers, e-mails, postcodes, addresses, birth dates, bank and card numbers and My Number in a CSV or Excel file, keeping their shape; a name has no shape to find, so a column headed like a name is hidden whole. For a PDF, Orihako PDF blacks out words you type or boxes you draw, turns those pages into images, and its leak check looks for what is left. A name in a column with another heading is not found: check every column and page before sending. Next: Send hands the file straight to one person's browser; Chat's list job does the column choices and the PDF in one plan.The page · Orihako Data · The page · Orihako PDF

AI Mask

AI Mask (orihako.com/ai-mask/): for people who must not give company secrets to an AI (free, no Pass). Before the person asks ChatGPT, Claude, Copilot or Gemini, the text gets placeholders like 【Company A】 【Person 1】 【Amount 1】; the answer gets the real names back, is checked for changed numbers and names, and is finished as Word, email text or Excel. Phones, emails, addresses and amounts are found by their shape; company and people's names come from the person's own list, plain-looking names (Ltd, Ms...) are offered with one press, and an optional name finder (a few hundred MB, loaded once from orihako.com when the person chooses) finds more. It can miss things. Masking and the key stay in the browser (never uploaded, deleted after 30 days). Files go to the tool for their kind, look kept: PDF; Word, PowerPoint and Excel; CSV and Excel lists; screenshots and photos of papers (pages below).

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.

What can Orihako do?

A private workflow for file work: tools that pass the file to each other on your device, steps kept as a recipe, and started again from Chat or an agent.

  1. Put a file in
  2. Tools hand it on, on this device
  3. Keep the steps as a recipe
  4. Start again from: The recipes page · Chat · A link · An AI agent

Files are never uploaded to a server

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 free and 2 GB with a Pass (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.

"Never uploaded": the exact truth

Files and file names are handled by the page on the person's own device and never uploaded to a server (Send delivers a file straight to the browser of the person chosen). Each site's security policy (CSP) fixes where the page may connect, and the "Network" chip in every tool's top bar lists the hosts the page itself has talked to (not what was sent, and not traffic from background workers or direct device-to-device connections). What does leave the browser:

  • The Pass check: each page checks the Pass with orihako.com through a small frame when it opens (no file or file name is included). The key itself goes out only when a Pass is activated: to orihako.com, which confirms it with the shop (Lemon Squeezy), or to the shop 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, 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.

Steps, Back and the work history

  • Steps: when work goes from one tool to the next, each step's files are kept in this browser for 24 hours (in orihako.com's storage on this device, never uploaded to a server). The browser's Back and Forward, a reload, or the steps strip above the tool bring an earlier step back as it was. A file over 500 MB, and every file while "Keep no step results" is on, is kept only while its page is open.
  • Work history: https://orihako.com/history/ lists what was done in this browser, by day (tool, files in and out; up to a year and 5,000 lines). It stays in this browser. A Business Pass adds a signed export for a team.
  • Recipes: several tools in a row for one job, such as redact, check for leaks, then send. Every recipe is listed at https://orihako.com/recipes.json (format orihako.work/1, open to any site).
  • Samples: Photo, Chat, Stream's editing studio and the PDF recipes have a sample to try, so a result shows without a file of your own.

Pricing

Free for good with no account, within each tool's free range (one file at a time, 50 photos, 30-minute videos, and so on). The Orihako Pass is one key for all nine tools: the 7-day pass at ¥980 (≈ US$6.20) (1 browser, the websites only), Pro at ¥4,980 (≈ US$32) 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$189) 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, Data, Find, Photo and Translate 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, the conversation and your files are processed on this computer. Only anonymous usage counts go out, and a file leaves only when you approve sending it (for example with Send).

Questions people ask assistants

Is Orihako free?
Yes: every tool has a free range, with no account and no time limit (one file at a time, 50 photos, videos up to 30 minutes and so on; it differs by tool). 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 and page views, AI model downloads, and for Send the connection setup (Send's file goes straight to the person chosen).
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.
Does it work offline?
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.
Which browsers work?
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.
Who makes Orihako?
Orihako is made and run in Japan. The Pass is sold through Lemon Squeezy, the seller of record. Contact: orihako.support@gmail.com.
