People still pay for Memtime because the timer is simple, but people pay for frictionless capture and a history they trust enough to invoice or change habits from. The recurring cost buys idle detection, permissions, app metadata, privacy, notifications, sync, reports, integrations, and backups, not just the visible interface.

what AI can build
Record local app activity and focused sessions privately, convert selected time blocks into timesheet entries, review patterns locally, and export a transparent activity record.
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Memtime, record local app activity privately and convert selected blocks into timesheet entries. The hard boundary is calendar and project integrations, team reporting, sync, and enterprise controls, plus ubiquitous capture, coaching, and team workflow.

the prompt
Catalog estimateBuild a personal replacement for Memtime in an empty repository. Use Tauri 2, React, TypeScript, SQLite, and optional OS accessibility APIs; do not offer alternative stacks. The core loop is: record local app activity and focused sessions privately, convert selected time blocks into timesheet entries, review patterns locally, and export a transparent activity record. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Create one-click start and stop, manual entries, idle detection, tags, projects, and notes. Keep any application-name tracking opt-in and never record window contents or keystrokes. Add Pomodoro-style focus sessions, break reminders, and an optional allowlist blocker. Provide daily, weekly, project, and category reports with editable corrections. Export CSV and JSON and make the underlying event log inspectable. Add automatic local backups and a privacy screen explaining every collected field. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Deliberately leave out employee surveillance. Deliberately leave out payroll and billing automation. Deliberately leave out cross-device blocking and behavioral coaching services. Finish by running the tests and listing the exact commands used.

questions
Can AI replace Memtime?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: calendar and project integrations, team reporting, sync, and enterprise controls, cross-device history. Validate the prompt against your own acceptance criteria before committing.
How much does Memtime cost?
Memtime is listed at about $15/month (Basic, checked 2026-07-31), or $180 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing Memtime?
Honestly: calendar and project integrations, team reporting, sync, and enterprise controls; cross-device history; team timesheets and payroll; behavioral datasets; blocking across every platform. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Memtime?
Yes — Kimai (Mature open-source time-tracking application with projects, reports, and exports.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
