What should your community share next?

How it works

A pipeline everyone can join.
Keys only you can hold.

Every post moves through the same suggestion → review → publish pipeline, so an idea from an intern gets the same care as a campaign from your agency.

Suggest

Contributors drop ideas, announcements and campaigns straight into the composer — with a suggested date, media, and tailored text per network. No account access needed.

Review

Approvers see everything in one inbox: comment, request changes, or approve. Native platform previews show exactly what will go out before anyone commits.

Publish

Publishers schedule the post and Copostr delivers it to every connected network, tracking status per platform — one network failing never blocks another.

Features

Everything a shared calendar needs

The future feed

One social-style timeline of everything planned across all your communities — filter by community or network, and see what's coming before it happens.

Comments & change requests

Discuss every post where it lives. Request changes, resolve them, and keep a complete activity log of who created, edited, approved and published what.

Per-platform versions

One post, tailored text for each destination — with character limits and realistic native previews for LinkedIn, Instagram, X and more.

Shared calendar

Drafts, suggestions, approved, scheduled and published posts in one month view — so gaps and pile-ups are obvious before they happen.

Credentials stay yours

Social account credentials are encrypted at rest and never shown to contributors. External collaborators can suggest — never connect, see or publish.

Per-platform delivery tracking

Queued publishing with status and error tracking per destination. If Instagram hiccups, your LinkedIn post still goes out on time.

Roles & permissions

Who can do what?

Five roles, enforced everywhere. Internal members run the pipeline; external contributors are a separate membership type that can only ever suggest.

Owner

Full control of the community, members, accounts and posts.

Editor

Create and edit posts and per-platform versions.

Approver

Review the inbox and approve, reject or request changes.

Publisher

Approve, schedule and publish posts to connected accounts.

Contributor

Suggest posts for review. Cannot publish or see credentials.

Internal vs external

Contributors are marked as external members — drafts stay private to their author, and each view only shows what your role can see.

Use cases

Made for teams with outside voices

Incubators & accelerators

Let every startup in your portfolio suggest posts for the program's accounts. Your team curates the feed; founders never need the passwords.

Agencies & clients

Collaborate with clients in one shared pipeline — they suggest and comment, you refine, schedule and publish across every network.

Brands & creators

Accept guest posts from partners, ambassadors and creators without handing anyone the keys to your brand accounts.

Companies & departments

Collect content from every department into one calendar, with comms keeping final say on what ships and when.
