AI Scheduler

Why AI Scheduler? (The Missing Autonomy Layer)

Every existing AI plugin in Obsidian is 100% reactive. They sit quietly until you open a sidebar, highlight text, type a prompt, and wait.

AI Scheduler is the only plugin of its kind: it brings true background autonomy to Obsidian.

Instead of treating AI as a disposable chat box, AI Scheduler gives your vault an autonomous knowledge worker that wakes up on schedule, processes your notes, uncovers connections, tracks open loops, and synthesizes daily reports—while you sleep or focus on deep work.

Reactive Chat vs. Autonomous AI Scheduler

Key Superpowers

🧠 1. Natural Language AI Planner

Describe an outcome in plain English, and AI Scheduler turns it into safe, recurring, structured jobs.

"Every evening at 10 PM, review notes I changed today, identify open loops, and write an executive summary to AI Reviews/." The planner interprets your intent, suggests optimal cron or interval cadences, and wires up the prompts and context bindings automatically.

⏱️ 2. Zero-Dependency Cron Engine

Need advanced cadences? AI Scheduler bundles an industrial-strength, dependency-free 5-field cron engine (minute hour day-of-month month day-of-week).

• Supports steps, ranges, lists, and named days (*/15 * * * *, 0 9 * * 1-5).
• DST-Safe: Predictably handles daylight saving transitions (spring-forward gaps and fall-back duplicates).
• Live Preview: See human-readable plain-English explanations and the next concrete run times validated live on every keystroke.

📝 3. Two-Way Synced Schedule Notes

Treat your schedules as first-class citizens in your knowledge graph. When enabled, every task is mirrored as a clean Markdown note in AI Schedules/:

• Edit the YAML frontmatter in Obsidian → the scheduler updates automatically.
• Edit the modal UI dashboard → your schedule notes update automatically.
• Notes include a rendered schedule table with cron syntax and upcoming run times.

🌙 4. Proactive Nightly Reviews & Daily Previews

Configure a nightly review time and context. The plugin autonomously:

1. Gathers all Markdown files created or modified during the day.
2. Directs your configured AI backend to analyze the day's thinking.
3. Produces a rich Markdown report detailing key progress, open loops, and action items.
4. Saves the report cleanly to <report folder>/YYYY-MM-DD-HHmmss.md.

⚡ 5. Event-Driven Vault Triggers

Set jobs to trigger whenever files within a specific project folder or note change. Smart cooldown debouncing ensures the AI doesn't fire continuously while you are actively typing.

🎛️ 6. Multi-Model Intelligence Matrix

Don't waste expensive frontier tokens on lightweight checks:

• Set Claude 3.5 Sonnet / GPT-4o for complex goal planning and deep nightly reviews.
• Set Claude 3.5 Haiku / GPT-4o-mini / Local Ollama for frequent interval checks and task summaries.
• One-click model refresh pulls newly added models straight from your backend.

🛡️ 7. Resilient Background Execution & Catch-Up

• Startup Catch-Up Window: If Obsidian was closed when a task became due, the plugin can intelligently run due tasks on next launch (configurable window, disabled by default for safety).
• Crash & Interrupt Recovery: Gracefully resets interrupted tasks without double-billing recurring schedules.
• Native Accessible Confirmations: Built with native Obsidian confirmation modals (ConfirmModal) for safe, accident-free bulk actions.

Quickstart & Installation

Option 1: Via BRAT (Recommended for Instant Updates)

1. Install the BRAT (Beta Reviewers Auto-update Tester) plugin from Obsidian Community Plugins.
2. Open BRAT settings and click Add Beta plugin.
3. Paste: https://github.com/racstan/obsidian-ai-scheduler
4. Click Add Plugin, then enable AI Scheduler under Community Plugins.

Option 2: Manual Installation

1. Go to the Latest GitHub Release.
2. Download main.js, manifest.json, and styles.css.
3. Create a folder in your vault at .obsidian/plugins/ai-scheduler/.
4. Copy the downloaded files into that folder.
5. In Obsidian, navigate to Settings → Community plugins, reload, and toggle AI Scheduler ON.

Prerequisites & Setup

AI Scheduler acts as the autonomy and scheduling layer. It drives your installed AI assistant plugins:

1. Install an AI Backend:
   • Claudian (recommended for Claude models & deep tool integration), OR
   • Obsidian Copilot (great for OpenAI, Gemini, and local LLMs).
2. In Obsidian Settings → AI Scheduler:
   • Choose your Active Backend Mode (Claudian or Copilot).
   • Configure your preferred model profiles for Planning, Tasks, and Reviews.
   • (Optional) Toggle Keep schedule notes in my vault to enable two-way Markdown note syncing.

Supported Schedule Types

Proactive Nightly Self-Talk

One of the most transformative features of AI Scheduler is the Nightly Review:

1. In settings, enable Nightly Review, pick your review time (e.g. 23:00), and choose your target report folder (default: AI Reviews).
2. At the scheduled hour, AI Scheduler automatically scans all notes you created or edited that day.
3. The selected backend reads and cross-analyzes the day's notes using live vault tools.
4. A structured, timestamped review note is synthesized into your vault:
   • Executive Summary: High-level synthesis of what you worked on.
   • Completed Work: Accomplishments recorded throughout the day.
   • Open Loops & Blockers: Unfinished thoughts, tasks, and follow-ups.
   • Tomorrow's Recommendations: Proactive suggestions to hit the ground running.

Commands

Open the Obsidian Command Palette (Ctrl/Cmd + P) and search for AI Scheduler:

• AI Scheduler: Open AI Scheduler: Open the interactive management dashboard.
• AI Scheduler: Ask AI to plan a schedule: Open the natural language goal planner.
• AI Scheduler: Run AI daily preview: Instantly generate a preview report for today's modified notes.
• AI Scheduler: Run AI nightly review now: Manually trigger the comprehensive nightly review on demand.
• AI Scheduler: Enable nightly AI review: Quickly toggle recurring nightly self-talk without opening settings.

Privacy and Safety

• No Proprietary Cloud / Zero Telemetry: AI Scheduler contains no third-party servers, no analytics, and no telemetry.
• Your Keys, Your Providers: Prompts and vault files are routed strictly through your chosen backend (Claudian or Copilot) to the provider APIs you have explicitly configured.
• Opt-In Reviews: Automated note reading and nightly reviews are strictly opt-in.
• Safe Quota Controls: Tasks support bounded iterations and explicit pause controls to ensure you never run unexpected recurring API calls.

Frequently Asked Questions

Does Obsidian need to stay open for jobs to run?

Yes. Obsidian plugins run inside the Obsidian desktop application environment. If Obsidian is closed, background timers pause. However, AI Scheduler includes a Startup Catch-Up Engine: when enabled, it checks for tasks that fell due while Obsidian was closed and executes them smoothly upon launch.

Can I edit tasks directly in Markdown?

Yes! Enable Keep schedule notes in my vault in settings. AI Scheduler creates a note for each task in AI Schedules/ with YAML frontmatter. Change the schedule or prompt directly in the note, and the scheduler syncs instantly.

What makes this different from other Obsidian AI plugins?

Every other plugin requires you to be sitting at your keyboard typing into a chat box. AI Scheduler is the only plugin that orchestrates proactive, time-based, and event-based autonomous execution in Obsidian.
