The problem
What it solves for a business
For: Small businesses, social media managers and agencies that post to several networks for one or more brands.
- Paying per channel adds up fast once we manage a few brands on several networks.
- Coming up with a month of posts for every network takes days.
- Clients want to approve posts, but they won't create an account just to click Approve.
How it works
SocialPostScheduler, step by step
- 01
Set up a workspace
Create a workspace per brand or client and invite your team with roles.
- 02
Teach your voice
Paste 3 to 20 sample posts and it builds a tone and vocabulary profile used in every AI call.
- 03
Plan the month
Write one brief and the AI month planner puts a draft per day per network on the calendar, with festival dates included.
- 04
Edit and approve
Tailor each network's version, then send posts through multi-step approvals, including a client link that needs no login.
- 05
Schedule
Drop posts into queue slots or the calendar; the best time is learned per channel from your own history.
- 06
Track
See totals, trends, best hours and top posts, and export a CSV or a print-to-PDF client report.

Agency features for everyone

Use cases
How teams use SocialPostScheduler
Festival month for a local shop
A sweet shop writes one Diwali brief and gets a month of drafts for Instagram, Facebook and WhatsApp on the calendar.
Agency with client sign-off
An agency sends each client a no-login link to approve next week's posts before they are scheduled.
Blog to social
A company connects its blog feed so each new article becomes a draft post in the queue.
Bulk campaign
A marketer uploads a CSV of 200 posts, checks the dry run, and schedules them in one go.
Under the hood
Where AI is used, and where it is not
The model
Qwen3.8-27B on Surge's own GPU server first; Claude Sonnet 5.5 as fallback (Claude Opus 5.5 for month plans); offline templates if both fail. Every call is logged with provider, tokens and cost.
Rules and code
Code checks every AI answer (JSON shape, length, script) before use, enforces each network's character limits, picks best times from your own post history, runs retries (1/5/15 min), token refresh and the stuck-publish sweeper, and keeps evergreen copies to at most 3.
People in the loop
Users edit every draft; contributors' posts go through approval steps; clients approve through a link; nothing is published unless a person schedules it or presses Publish now.
