Threads scheduler for text, photo, video, and carousel posts
PostQuest is a Threads scheduler for text posts, link posts, photos, videos, and carousels of up to 20 items. You write the post, add media, and pick a time. Before the post is scheduled, PostQuest checks the text against Threads’ 500-character limit and every file against Meta’s media rules.
The Threads app can schedule posts itself, and for one profile that may be enough. PostQuest is for people who post the same idea to Threads, Instagram, X, and Bluesky, run several Threads profiles, or want an AI assistant to draft posts they approve.

What you can schedule on Threads
PostQuest checks every Threads post against these limits before it is scheduled. They come from the same rules that power the composer, last checked against Threads’s API documentation on September 11, 2026.
| Format | Files | Limits |
|---|---|---|
| Text Post | No media | Caption only |
| Link Post | No media | Caption only |
| Photo Post | 1 file | Up to 8 MB · JPEG, PNG |
| Video Post | 1 file | Up to 1 GB · 1 s–5 min · MP4, MOV |
| Carousel Post | 2–20 files | Up to 8 MB / Up to 1 GB · 1 s–5 min · JPEG, PNG / MP4, MOV |
Captions can be up to 500 characters. Hashtags: 1 per post. See every dimension, aspect ratio, and codec on the Threads post size and specs page.
the Threads app vs PostQuest
Threads added post scheduling in January 2025. You write a post, open the composer menu, and pick a date and time; scheduled posts wait in Drafts, where you can edit or delete them before they go live. Meta’s help center doesn’t document how far ahead you can schedule.
| Feature | the Threads app | PostQuest |
|---|---|---|
| Price | Free | From $15 a month after a seven-day trial |
| Where you schedule | The Threads composer | A web calendar, plus Claude or ChatGPT over MCP |
| Formats | Threads posts | Text, link, photo, and video posts, and carousels of 2 to 20 photos and videos |
| Checks before posting | None documented | Text length, file type, size, resolution, and video length |
| Other networks | Threads only | Nine more, including Instagram, X, and Bluesky |
| AI assistants | Not part of this comparison | Claude and ChatGPT draft and schedule over MCP, with your approval |
Use the Threads app if you post to one profile and only to Threads. Use PostQuest when Threads is one of several networks, you manage more than one profile, or you want every post checked against Threads’ limits before it goes out.

Which Threads accounts can you connect?
Connect a Threads profile through Meta’s login and approve PostQuest’s access. Each profile counts as one account on your plan.
- You can connect several Threads profiles and send one post to more than one of them.
- Meta allows up to 250 posts per profile in a rolling 24 hours through its API; a carousel counts as one post.
- If Meta revokes access, the profile shows Reconnect. Failed posts can be retried once it is reconnected.
How to schedule Threads posts in PostQuest
Step 1: Connect your Threads profile
Open Connections, choose Threads, and sign in with Meta. Repeat for each Threads profile you manage.
Step 2: Select the profile and write the post
Choose the Threads profile in the composer and write up to 500 characters. If you post to other networks too, give Threads its own shorter version.
Step 3: Add photos or a video
Attach one JPEG or PNG photo up to 8 MB, one video up to 5 minutes, or a carousel of 2 to 20 photos and videos.
Step 4: Check the requirements
Open Media requirements to see the Threads limits PostQuest checks: file types, sizes, image width, and video length, frame rate, and bitrate.
Step 5: Choose a time and schedule
Pick a date and time in your workspace time zone and click Schedule. Posts that are pending approval wait until someone approves them.
Schedule Threads posts from Claude or ChatGPT
Connect PostQuest to Claude or ChatGPT over MCP and ask for posts in plain language. The assistant creates drafts by default; scheduling, publishing, and deleting need your explicit approval.
“Turn these release notes into a Threads post under 500 characters and save it as a draft.”
“Make a Threads version and a Bluesky version of my latest X draft, then validate all three.”
“Schedule the approved Threads post for tomorrow at 8 a.m. Toronto time.”
Why a Threads post fails, and how to fix it
PostQuest catches these before scheduling, so you fix them in the composer instead of finding a failed post later.
- Text over 500 characters
- Threads posts are capped at 500 characters. Shorten the Threads version; your other networks keep their own captions.
- A WebP or GIF image
- Threads photo posts take JPEG or PNG files up to 8 MB and 320 to 1,440 pixels wide. Convert the image first.
- A video longer than 5 minutes
- Threads videos must be MP4 or MOV, up to 5 minutes and 1 GB. Trim the video or post a shorter cut.
- More than 20 carousel items
- A Threads carousel takes 2 to 20 photos and videos. Split larger sets into two posts.
- The profile needs reconnecting
- If Meta revoked PostQuest’s access, reconnect the profile in Connections, then retry the failed post. Other networks in the same post are not affected.
