Acknowledge

Acknowledge is a lightweight web app built to solve a small but common daily-life problem: verbal commitments between friends, roommates, or colleagues often fail because they are forgotten or unclear.

Instead of long chats or awkward follow-ups, Acknowledge lets people write one short statement, mutually acknowledge it, and optionally get a reminder without accounts, legal tone, or complexity. It focuses on clarity, neutrality, and low friction.

Problem

In shared living spaces (PGs, hostels, flatmates) and daily work life, people make small promises like:

- "I will pay the electricity bill."
- "I will return this in 3 days."

These are usually verbal or buried in chats, leading to confusion, delays, and unnecessary friction.

Solution

Acknowledge provides:

- One short written statement (max 200 characters)
- Mutual acknowledgment by both parties
- Optional due date and reminder
- Automatic expiry after 14 days
- No user accounts, no dashboards, no editing after acknowledgment

Key Features

- Anonymous, session-based usage (no signup required)
- Mutual acknowledgment to reduce ambiguity
- Neutral reminders without guilt or pressure
- Auto-expiry to protect privacy
- Mobile-first, responsive design
- Shareable link-based flow
