Yash Kumar Sinha
Computer Science at VIT Vellore · India
I'm a computer science student at VIT Vellore, graduating in 2027. What gets me going is software that works for many people at the same moment: live dashboards, chat, multiplayer games, and now documents.
At Tejas Networks I built a document platform on my own, with versions, approvals and permissions. It made one thing clear. Programmers have had branches for years: take a copy, try something risky, merge it back only if it works. People who write together still have tracked changes and files named final-v3-really-final.docx.
So I built LowKey: the editor, the sync and branching engine underneath it, the server, and the privacy groundwork for launching in India. I care about the details people notice, like a resume that imports as one page or a phone screen that never scrolls sideways.
LowKey is in beta now, opening to a new group every few days. If you try it, tell me what works and what doesn't. I read everything.

LowKey
Everything I learned about documents and real-time systems, in a product of my own.
What I built into LowKey
- Live editor
- Many people typing in one document, with cursors, offline edits that sync later, and comments with @mentions.
- Branches and merging
- A three-way merge by paragraph, a review before every merge, a choice on conflicts, and undo.
- History
- Snapshots you name yourself, automatic versions, safety copies before merges and restores, and a branch tree.
- Pages
- Page view, page setup, Word import that keeps the layout, and export to PDF, Word, Markdown and HTML.
- Workspace
- Folders, organisations with roles, sharing that takes effect on live connections at once, and full-text search.
- Privacy
- Consent, data download and account deletion built to India's DPDP Act 2023 and the IT Rules 2021.
