Step 2

ChatGPT

Simplify the language

Format gone. Have to rebuild from text dump.

Step 3

Terminology slips. Glossary not enforced.

Step 4

PowerPoint

Manually fix everything

Two hours per file. Every. Single. Time.

We built one app for all of it. Layout intact.

Early access feedback

What early users are saying.

From sales teams, designers, and ops leads who got their workflows back.

“

We used to send PowerPoints to a translation agency and wait three days. Now I drop the file at lunch and email the deck before I'm done with my coffee.

VP of Sales · enterprise SaaS

“

What sold me was the layout. Other tools turn my deck into a wall of text. This one keeps the charts, the tables, the brand fonts — exactly as I built them.

Yuki S.

Product designer · Tokyo

“

I was skeptical about the BYOK model — turns out it saves us money. We already pay for OpenAI; why pay another vendor for the same tokens?

Why we built this

Every translator we know hated their workflow.

We watched a colleague spend an entire Saturday translating a 60-slide deck for a Monday board meeting. Copy, paste, translate, paste back, fix the layout, fix the font, fix the chart that wrapped wrong. Repeat 60 times.

That Saturday became this app — and the Mondays that followed.

No subscriptions. No data lock-in. Use your own DeepL or OpenAI key — we never see your text. Pay once. That's it.

Our principles

Your data stays yours
We never see your files or text. The app talks directly to DeepL or OpenAI from your machine, with your own API key.
One price. All features.
Annual per-device license. No upgrade tiers. No "Plus" or "Pro" upsells. The price is the price.
Layouts come through untouched
Fonts, tables, formulas, embedded objects — preserved bit-for-bit. Your finished file looks like your source file.
Sound like a person
Outputs adjust to register: friendly emails, formal contracts, plain-language briefings — never a translation artifact.

Pricing

One price. All features.

Annual license. No tiers, no upsells, no surprise charges. AI usage is billed by DeepL or OpenAI directly to you — never to us. Cancel anytime.

Questions, answered honestly.

If yours isn't here, email us at contact@h-insight.jp.

What does “use your own AI key” (BYOK) mean?

You bring your own API key from DeepL, Google, Azure, Claude, Gemini, or OpenAI. AI usage is billed by those providers directly to you, never to us — and most teams stay inside their providers’ free tiers (around 3M characters per month, combined). It keeps your AI costs transparent and under your control.

Where do my documents go?

Nowhere. The app runs on your PC, and only the text you choose to translate ever reaches an AI provider — using your own API key, billed directly to you. File structure, metadata, and unselected content never leave your machine.

What currency will I be charged in?

USD ($199 / $499). At checkout, Lemon Squeezy converts to your local currency at the current rate and handles tax and invoices in one step — whether you’re in the US, EU, UK, India, or anywhere else. Customers in Japan should use insight-office.com, which carries a separate JPY-priced tier.

What if it doesn’t work for me?

Start with the free trial — full features, no credit card required — so you can confirm it fits your workflow before you ever pay. For billing issues (defects or double charges) or to stop auto-renewal, just email support@h-insight.jp.

Does it work on macOS or Linux?

Built first for Windows — that’s where Office gets done. macOS is on the roadmap; sign up for the newsletter and we’ll email you when it lands.

How is this different from DeepL?

DeepL is excellent at the translation itself — we use it as one of our engines. The difference is what happens to the rest of your file. DeepL doesn’t preserve PowerPoint layouts well, can’t simplify or summarize, and locks you into one engine. We keep your layout intact, let you switch between six engines per row, and fold simplify, summarize, and refine into the same workflow.

Can I share licenses with my team?

Yes. Pick the Business plan ($499 per seat per year) and add as many seats as you need — one seat per device. Business also unlocks a shared glossary and translation memory across the team.

What languages does Simplify support?

Every target language can be rewritten to a lower proficiency level — CEFR for European languages, JLPT for Japanese, HSK for Chinese, TOPIK for Korean. The AI adjusts vocabulary and grammar to match the level you set (down to A1/A2).
