Documents and notes decision
iLovePDF Premium
A competent developer can implement the core PDF tools and basic AI summarization in about a week, but cannot reproduce iLovePDF’s global scale, enterprise compliance, desktop/mobile apps, and SLAs — so building a narrow replacement is realistic, replacing the full paid product is not.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Allow users to upload PDFs, run transformations (merge/split/convert/compress), perform OCR and basic AI summarization, and return processed files for download.
What it still won’t have
- global scale and reliability/infrastructure
- ISO27001-level compliance and enterprise contracts (SSO, dedicated account manager)
- desktop and mobile packaged apps
- priority customer support and SLAs
- regional file-processing infrastructure and 7+ regions
What remains hard
- Infrastructure at scale
16.5 million documents processed every day
- Compliance and regulation
ISO27001 certified
First-year cost
Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 7 seats.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted PDF web service using Node.js (Express), Postgres (or SQLite for single-host), Redis (for queue), and pdf_oxide (or pdf-lib) plus Tesseract for OCR. Implement: 1) an authenticated upload endpoint that stores files temporarily, 2) background worker jobs to run merge/split/convert/compress and OCR, 3) an API to request AI summaries that calls an external LLM (configurable OpenAI key), 4) a simple React web UI for uploads, job progress, and downloads, 5) automatic cleanup of temp files after N hours. Out of scope: mobile or native desktop apps, ISO27001 certification, global regional processing, SSO, enterprise billing. Include robust error handling, retries for worker tasks, logging, and unit tests for API endpoints and worker logic.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
