The problem
Where spreadsheet work goes wrong
Most teams that tried AI ended up back at copy and paste. The work arrives as paper, scans, faxes and spreadsheets, and none of it lines up.
Reports rebuilt from scratch
Raw data lands in Excel. Aggregating it, charting it and writing it up for the internal report is manual work, repeated monthly.
One person holds the knowledge
How the files are structured and where they live sits with one person. When they are away, the process stops.
Solution
What Ichiyomi Sheet does
An agent that takes your Excel and PDF files as they are and runs the whole chain — read, aggregate, report, draft the email.
BEFORE — how it works today
- Read the invoice, retype the values
- Rebuild the totals with formulas and copy-paste
- Format the report from a blank page
- Write the covering email from scratch
AFTER — with Ichiyomi Sheet
- Ask for the summary in chat
- It reads the files, aggregates, and builds the tables and charts
- Word and PowerPoint reports and a draft email come with it
- It remembers the procedure and repeats it next time
In & out

Hand over the files as they are. English and Japanese documents both go in unchanged, and what comes back is ready to use.
What you hand over
- Invoices and purchase orders (PDF)
- Business cards (images)
- Scanned handwritten forms
- Faxed documents
- Excel and CSV
What comes back

- PowerPoint decks

Why us
How it compares
General-purpose chat AI is good at reasoning. Knowledge platforms are good at organising. Ichiyomi Sheet applies both to the spreadsheet work itself.
| Comparison | ChatGPT Web | Notion | Ichiyomi Sheet |
|---|---|---|---|
| Built for | General-purpose chat | A knowledge base | Automating and sharing spreadsheet work |
| Your existing Excel and PDFs | Usable as they are | Assumes migration | Used as they are |
| How far it automates | Generates text | Assists authoring | Aggregation through to a draft email |
Here, "knowledge base" means turning the procedures, master data and history around your spreadsheet work into structured data.
Security
Where your data goes
The question that matters is where the data ends up. It is not used for training, and it does not accumulate with an AI provider.
Not used for training
We use commercial APIs whose terms rule out using inputs or outputs to train models.
Nothing accumulates outside
Your data is stored on Amazon's cloud servers to run the service, and nowhere else. It does not build up on the AI provider's side.
Encrypted and hardened
Traffic is encrypted in transit, and the deployment follows the security standards Amazon's cloud platform sets out.
