A written promise to do — or not do — something specific: repay a loan on schedule, follow workplace or hostel rules, or any one-sided commitment someone is asking you to put in writing. Pick the type, fill the details, get a properly worded letter. No signup, nothing leaves your browser.
It's a written promise by one party to do (or not do) something specific, addressed to the person or organisation relying on that promise. It's less formal than a contract but still creates a documented commitment — commonly used for financial repayment promises, workplace commitments, student/institutional discipline, or any one-sided assurance.
No — the GST LUT (under Rule 96A) that lets exporters ship without paying IGST upfront is a specific statutory filing done directly on the GST portal (Services → User Services → Furnish Letter of Undertaking), not a document you print and hand over. This tool is for the general-purpose letters of undertaking used outside that GST filing process. See our export invoice tool's LUT guide for the GST filing itself.
It can be, depending on how it's worded and whether it's accepted by the other party — but it is generally weaker evidence than a registered contract or an affidavit sworn before a notary. For high-value or high-risk commitments, consider having it reviewed by a lawyer or executed as a formal agreement instead.
Not always — many workplace and institutional undertakings are simply signed on plain paper or letterhead. Financial undertakings involving larger sums are sometimes asked to be on stamp paper — check with whoever is requesting the letter. Need something that's typically executed on stamp paper instead?

No. The letter is generated entirely in your browser — nothing is uploaded to a server.
