Every post needs media — no exceptions
Instagram's API rejects text-only posts. Forgetting to attach an image until publish time means starting over or posting from your phone while your audience waits.

Publish to Instagram automatically
Visual platforms need visual consistency. Content Drifter generates captions tuned for Saves and Sends, validates 1080×1080 / 1080×1350 media, and auto-publishes feed posts and Reels to your connected Business account.
3 reasons publishing to Instagram manually is broken
Hashtag stuffing backfires
Up to 30 hashtags are allowed, but the algorithm rewards relevance over volume. Copy-pasting the same 30 tags on every post triggers reach decay.
Reels specs differ from feed specs
Reels want 9:16 vertical video up to 15 minutes; feed posts want 4:5 to 1.91:1 aspect ratios. Wrong dimensions look cropped or blurry in Explore.
What Content Drifter does for Instagram
Business/Creator account support
Connect via Meta OAuth for Instagram Business or Creator accounts — required for third-party publishing.
Media validation + auto-compress
Images over 8 MB are compressed to fit Meta's Graph API limit before publish. Reels and feed posts each carry content-type rules.
Starter plan and above
Instagram auto-publishing unlocks on Starter ($19/mo) alongside Facebook. Free tier covers X + Threads generation and publishing.
Brand-aligned visuals
AI image generation and carousel maker apply your Brand Kit colors and fonts so feed posts look designed, not templated.

Frequently asked questions
How do I publish to Instagram automatically?
Upgrade to Starter or above, connect Instagram from Platforms (Meta OAuth), attach media in Final Review, and schedule or publish. Captions are validated against the 2,200-character limit before dispatch.
Is Instagram auto-posting allowed?
Yes, through Meta's official Instagram Graph API with a Business or Creator account. Content Drifter uses approved OAuth — not unofficial scraping.
Can I schedule Instagram Reels?
Yes. Reels content type rules (9:16, up to 15 min, ≤300 MB video) are enforced at validation so the API accepts your upload.
Do I need a Business account?
Yes. Personal Instagram accounts cannot use the publishing API. Convert to Business or Creator in Instagram settings before connecting.
How many images can I publish in one Instagram post?
Up to 10 images in a carousel, per PLATFORM_RULES. Each image must meet JPEG/PNG format and size limits.
