Setup

Up and running in 60 seconds

1

Connect Threads

OAuth via your Threads account. Threads scopes are independent of Instagram — connect both for cross-publish.

2

Compose the chain

Write the lead post. Use the chain composer to draft replies as a thread. Add image, video, or link cards per post.

3

Schedule or publish

Schedule the lead and we'll publish the replies in order. Each reply waits for the previous one to publish before firing.

What you can do

Use cases with Threads

Reply chains

Draft a 7-post thread, schedule the lead, and we'll fire each reply in sequence with the right delay.

Cross-post from IG

Compose once, publish to Instagram + Threads in one action. Captions adapt to each platform's feel.

Photo + video

Threads accepts up to 10 media per post. We handle the carousel container flow.

FAQ

Common questions

Can I auto-cross-post my Instagram posts to Threads?
Yes — toggle Threads in the composer when posting to Instagram. Same media, threads-tuned caption.
How long can a Threads post be?
Threads allows ~500 characters per post. LetsPost's composer warns you before publish if you're over.
Do reply chains publish atomically?
No — each reply publishes after the previous succeeds. If a mid-chain reply fails, we surface the error and stop; the published parts stay live.
What about Threads-only video formats?
We ship the formats Meta's Threads API exposes today. As Meta adds new media types, we'll wire them in.
