Insight Office
Edit PDFs, compare documents, and put your own AI to work — in one Windows app, for one flat yearly price. No monthly PDF subscription.
Windows 10 / 11 · 64-bit · EV code-signed · works alongside MS Office
Four tools, one app
Insight Office bundles the document work you keep paying separate tools for — PDF editing, file comparison, spreadsheet analysis, and AI — into a single desktop app you own for the year.
PDF editor
Annotate, edit text & images, fill forms, e-sign, OCR scanned PDFs, organize pages (extract / merge / delete / reorder) and password-protect. Save without a watermark and export to PDF — everything you actually do with a PDF, in one place.
Compare documents — down to the cell & character
Line up two versions of a Word, Excel, PowerPoint or PDF file and see exactly what changed, down to the cell and the character. Save, export and bulk-copy the results. Runs entirely on your device.
Excel logic analysis
Visualize formulas and dependencies so you can finally answer “where did this number come from?” — ideal for the complex spreadsheets you inherit.
AI concierge — your own key (optional)
Summarize, proofread, translate and even edit Office files with AI, using your own API key (Claude / OpenAI / Gemini). Editing, comparison and analysis run locally; when you use AI, your data goes only to your own key — personal information is anonymized before sending and never passes through our servers.
One flat yearly price
Free to download with a 30-day full-feature trial. After the trial it continues as a free, view-centric tier; saving, exporting and advanced PDF features need a license. Annual, auto-renewing. Payments and global tax are handled by LemonSqueezy (Merchant of Record). Cancel anytime.

Local by default. Your keys, your data.
Opening, editing, comparing and analyzing all happen on your PC — nothing is sent to our servers. AI is optional and runs on your own API key, with personal information anonymized before it is sent to the provider you choose.
