Any.do
Manage personal tasks, lists, reminders, recurring items, and a daily planning flow
The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Any.do, manage personal tasks, lists, reminders, recurring items, and a daily planning flow. The hard boundary is mobile capture, widgets, family features, calendar integration, and sync, plus cross-device reliability and workflow polish.
Build verification: not recorded. How we judge buildability
What you give up
- mobile capture, widgets, family features, calendar integration, and sync
- perfect mobile sync
- calendar and email integrations
- shared workspaces
- behavioral coaching polish
Why people still pay
People still pay for Any.do because task software is sticky because trust, speed, and ubiquitous capture matter more than the database schema. The recurring cost buys recurrence edge cases, notifications, sync conflicts, calendar APIs, mobile capture, and backups, not just the visible interface.
Your build guide
The stack, security requirements, and agent rules for a focused replacement.
Before you start
- Node and the Rust toolchain, a supported desktop build environment and an explicitly selected data folder. Remote sync is outside the initial scope.
- Implementation components: Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge. SQLite for structured state and search; user-owned files for original documents and attachments.
- Scope boundary: mobile capture, widgets, family features, calendar integration, and sync; perfect mobile sync
Use these project rules and optional skill references alongside the prompt. Review each skill before adding it to your agent; the AGENTS.md export includes the same guidance.
Optional external skill: vercel-react-best-practices — Improve React and Next.js data fetching, rendering, bundle size and server performance. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Optional external skill: web-design-guidelines — Review web interfaces for accessibility, keyboard focus, forms, navigation and interaction quality. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Optional external skill: sharp-edges — Review security-sensitive APIs and configuration for dangerous defaults and easy-to-misuse interfaces. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Project rule — data model: tasks, lists, subtasks, recurrence rules, reminders and daily-review decisions
Project rule — preserve this invariant: Completing a recurring occurrence creates at most one successor; a parsed date must be confirmed before a reminder is scheduled.
Project rule — acceptance evidence: Complete the same weekly task twice during an offline restart and see one next occurrence; snoozing one reminder leaves the original due date intact.
Implementation plan
Phase 1
Scope and fixtures. Implement this bounded workflow: Capture tasks with a preview of parsed dates, group them into lists, and walk through today's and overdue tasks in a daily planning deck. Support complete, defer and snooze with an editable history. Record prerequisites, select representative user-owned fixtures and document the unsupported features: mobile capture, widgets, family features, calendar integration, and sync; perfect mobile sync
Phase 2
Durable model. Model tasks, lists, subtasks, recurrence rules, reminders and daily-review decisions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Completing a recurring occurrence creates at most one successor; a parsed date must be confirmed before a reminder is scheduled.
Phase 3
Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.
Phase 4
Permissions and integration failure. Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
Phase 5
Portable handoff. Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
Phase 6
Acceptance scenarios. Complete the same weekly task twice during an offline restart and see one next occurrence; snoozing one reminder leaves the original due date intact. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Questions about Any.do
Can you build your own Any.do with AI?
The verdict is yes for the scoped workflow. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Any.do, manage personal tasks, lists, reminders, recurring items, and a daily planning flow. The hard boundary is mobile capture, widgets, family features, calendar integration, and sync, plus cross-device reliability and workflow polish.
What does the Any.do build prompt cover?
The prompt starts with this scope: Capture tasks with a preview of parsed dates, group them into lists, and walk through today's and overdue tasks in a daily planning deck. Support complete, defer and snooze with an editable history. Full-product capabilities excluded from the comparison include: mobile capture, widgets, family features, calendar integration, and sync; perfect mobile sync; calendar and email integrations. Follow the implementation plan and its prerequisites before expanding the build.
How do I use the prompt, AGENTS.md and agent skills?
Start with the Any.do prerequisites and stack, then copy the prompt into your coding agent. Save the project rules as AGENTS.md in the project root. Linked skills are optional packages or source instructions for specific tasks; review their current contents and install only those matching the chosen stack. A skill does not supply API credentials or verify the finished app.
How long will this Any.do project take?
The catalogue estimate is one sitting for the limited scope. Setup, integration approvals, debugging, deployment and ongoing maintenance can add time. This is an estimate, not a delivery guarantee.
What would I give up by replacing Any.do?
mobile capture, widgets, family features, calendar integration, and sync; perfect mobile sync; calendar and email integrations; shared workspaces; behavioral coaching polish. People still pay for Any.do because task software is sticky because trust, speed, and ubiquitous capture matter more than the database schema. The recurring cost buys recurrence edge cases, notifications, sync conflicts, calendar APIs, mobile capture, and backups, not just the visible interface.
What price is this guide comparing against?
The recorded Premium plan is $7.99/mo (monthly), checked 2026-07-31. Check the linked pricing source before buying. Building your own also has hosting, API and maintenance costs; the recorded amount is not a guaranteed saving.
What can I use instead of building Any.do?
Tasks.org: A serious Android task list with recurrence and reminders; desktop and CalDAV sync are paid. Vikunja: A capable Todoist replacement once you accept becoming its hosting department. Microsoft To Do: A polished free task manager, paid for with a Microsoft account rather than money. Compare all listed options at https://howtovibecodeit.dev/anydo/alternatives.
