Why Narrareach
More than a Substack Notes scheduler.
Narrareach starts with search-visible workflows writers already ask for: Substack Notes scheduling, Medium publishing, Substack MCP, Medium MCP, cross-posting, and attribution.
Cloud Substack scheduler
Schedule Substack Notes and articles from a web dashboard so publishing does not depend on an open browser session.
Medium and social publishing
Adapt one idea for Medium, LinkedIn, X, Bluesky, and Threads without rebuilding the post in every editor.
Substack MCP and Medium MCP workflows
Use Claude, Cursor, ChatGPT, or any MCP-compatible client to draft, schedule, inspect queues, and publish.
Subscriber attribution
See which posts drive subscribers, replies, clicks, and engagement across every publishing channel.
Where StackSweller falls short
The gaps show up when publishing becomes a system.
StackSweller can be useful for a focused Notes workflow. The limitation is that writers usually need more than one scheduler: platform coverage, queue control, analytics, and automation all have to work together.
Requires an active browser session — posts fail if the tab or browser closes
Substack Notes only — no cross-posting to other platforms
No analytics or subscriber attribution
No bulk CSV import
No drag-and-drop queue reordering or requeue
No Substack MCP, Medium MCP, API, or webhooks

Once you need cloud reliability, Medium publishing, cross-posting to LinkedIn or X, subscriber tracking, or programmatic control through MCP, you have outgrown it.

Who should switch
The right tool depends on the job.
StackSweller is a reasonable starting point for a Substack-only Notes workflow. The ceiling appears the moment your browser closes unexpectedly, you want to cross-post to LinkedIn or Medium, you want to see which posts are actually driving subscribers, or you want to control publishing from Claude through Substack MCP and Medium MCP workflows. Narrareach is the cloud-based step up that covers all of this without losing the batch scheduling that made StackSweller useful in the first place.

Questions writers ask
What's the main difference between StackSweller and Narrareach?
StackSweller is a Chrome extension that batch-schedules Substack Notes. It requires an open browser to publish. Narrareach is a cloud platform — it publishes on schedule with no browser required, covers 6 platforms beyond Substack, repurposes articles with AI, tracks subscriber attribution, and exposes a REST API, webhooks, and MCP server for developer workflows.
Why does cloud scheduling matter if StackSweller works for me?
Browser-based tools fail silently when your browser is closed, your computer is asleep, Chrome updates mid-session, or you are traveling. Cloud infrastructure publishes reliably regardless of device state. For a publishing cadence that matters to your audience, reliability is not optional.
Can I keep my batch scheduling workflow when switching?
Yes. Narrareach's batch calendar covers the same batch-scheduling pattern as StackSweller, with added controls: drag-and-drop reorder, bulk CSV upload, and queue management from mobile. The workflow is faster, not harder.
Does Narrareach support CSV bulk upload?
Yes. Prepare a CSV with post content, platform targets, and scheduled times. Upload it to Narrareach and it imports and schedules everything at once. Useful for planning an entire month in one session or migrating a backlog from another tool.
How does queue reordering work?
Narrareach's queue view lets you drag and drop posts to change their order, promote a post to the next available slot, requeue a published post to run again on a future date, or bulk-reschedule a range. StackSweller has no equivalent queue controls.
What social platforms can I add beyond Substack?
Currently: LinkedIn, X, Medium, Threads, and Bluesky alongside Substack — six platforms total. Instagram, YouTube, Pinterest, and TikTok are on the roadmap. Each platform gets per-post formatting adapted for its native style.
What are auto-subscribe CTAs?
When Narrareach cross-posts your content to Medium or LinkedIn, it automatically appends a call-to-action inviting readers to subscribe to your Substack. You configure the CTA text once per platform and it applies to every cross-post automatically.
How does AI repurposing work?
Paste or import any article URL. Narrareach AI reads it, extracts key insights, and generates 10+ Substack Notes written in your voice. Review, edit, approve the ones you want, then bulk-schedule them across future weeks in a single step.
Does Narrareach support Substack MCP and Medium MCP workflows?
Yes. MCP (Model Context Protocol) lets AI tools like Claude Desktop, Cursor, and ChatGPT control external services. Narrareach's MCP server lets you schedule Substack Notes, schedule Medium articles, manage queues, import articles, and pull analytics directly from your AI assistant in natural language — no dashboard required.
Does Narrareach have a REST API and webhooks?
Yes. The REST API covers scheduling, content import, queue management, analytics, and comment retrieval. Webhooks fire on post published, post failed, subscriber gained, and queue updated events — letting you connect Narrareach to any downstream system.
How does subscriber attribution work?
Narrareach appends UTM parameters to links in your posts. When a reader clicks through and subscribes to your Substack, the conversion is traced back to the specific post and platform. The analytics dashboard shows subscriber gain per post, per platform, and over time.
Is there a free plan?
Yes. Narrareach has a free plan with no credit card required. Paid plans start at $19/month for higher-volume publishing and advanced workflows.
What if I just want Substack Notes and nothing else?
Narrareach covers that too — and does it from the cloud with better queue controls than StackSweller. If you later want LinkedIn cross-posting or subscriber tracking, it is already there. No migration needed.
