EnglishWhat is HocHanh?
Updated
HocHanh (hochanh.github.io) is a personal collection of small, experimental web tools hosted on GitHub Pages. Its own tagline — "Experiments that don't always work!" — sets the expectation: these are side projects rather than polished, supported products. The site groups several independent utilities under one roof, spanning Japanese learning, PDF handling, image editing, and music practice.
What tools does it offer?
Based on the site's own headings, the current lineup is:
| Tool | Purpose |
|---|---|
| RTK-search | A search engine for Kanji stories (aimed at learners using the Remembering the Kanji method) |
| PlainMerger | A PDF mail merger |
| Mergram | PDF mail merge, described as "made simple" |
| PlainRemover | An image background remover |
| MuseTrainer | A MusicXML piano trainer |
| Temway | An on-brand email builder |
Each tool stands alone. There is no shared account system or unified dashboard implied by the page — you pick the tool you need and use it directly.
Who is it for?
The mix of tools points to a few overlapping audiences:
- Japanese learners who study kanji through story-based mnemonics and want to search existing stories (RTK-search).
- Anyone doing repetitive document work — merging PDFs with mail-merge data (PlainMerger, Mergram).
- People who need a quick background removal without opening a full image editor (PlainRemover).
- Musicians and piano students working with MusicXML files who want practice support (MuseTrainer).
- Small senders who want a branded email built quickly (Temway).
If you fall into one of these groups and want a lightweight, browser-based option, it may be worth a look.
What to keep in mind before relying on it
The "experiments that don't always work" framing is the key caveat. Treat these as:
- Unstable by design — features may break, change, or disappear without notice.
- Not a service — there is no indication of uptime guarantees, support, or a maintenance schedule.
- Best for one-off or low-stakes tasks — fine for a quick PDF merge or a background removal, less suitable as a critical part of a workflow.
For anything you'd depend on repeatedly or professionally, verify the output yourself and keep a fallback tool in mind.
How to get started
- Go to hochanh.github.io.
- Pick the tool matching your task from the list on the page.
- Open it and follow its own on-screen instructions — each tool has its own interface and inputs.
- Check the result before using it, given the experimental nature of the projects.
There is no sign-up flow described on the landing page, so expect to use the tools directly rather than through an account.
