A Threads post generator is any tool that drafts or designs posts for Threads, Meta's text-first app, and the useful ones split the job in two: words and visuals. AI is good at the first draft of the words. An editor is where the image or video gets made. This page covers both, briefly.
What does a Threads post need?
Less than a reel, which is the appeal. Threads is built around text, with optional media:
| Part | Limit or guide | Tip |
|---|---|---|
| Text | Up to 500 characters | The first line does the work; most posts need far less |
| Images | Optional, one or several | Show the thing the text is about |
| Video | Optional, up to 5 minutes | Short clips in the feed are the norm |
| Replies | Your own replies extend a post | Put detail or a link in a reply |
The text is the post. A visual helps when it shows what you're talking about: the product, the before and after, the screenshot. It doesn't help when it's decoration.
How do you use a Threads post generator for the text?
Use AI for the draft, not the final word.
- Give it your material. Paste your notes, a blog post or the points you want to make. An AI given nothing writes generic posts; an AI given your facts writes yours.
- Ask for options. "Write five Threads posts under 300 characters from these notes, each opening with a different first line." Comparing options is faster than fixing one.
- Rewrite in your voice. Cut the words you'd never say. Check every fact, because AI can state things confidently that aren't true.
- Read the first line alone. In the feed, that line is often all a reader sees before deciding. Reel hooks: the first three seconds is about video, but the same rule applies.
Claude and ChatGPT both do this well when you give them material. Dedicated Threads post generator tools wrap the same idea in templates; they save a prompt, not the editing.
How do you make a week of Threads posts in one sitting?
Batch the parts that are the same and keep the parts that should be fresh.
- Monday, 30 minutes: paste the week's notes into the AI and ask for ten drafts. Keep the best five, rewrite them.
- Visuals in one pass: make every image or clip for the week at once, using one layout, so you only set fonts and colours one time.
- Leave room for the day. Threads is a conversation app, so keep time to reply and to post about what's happening; don't fill every slot in advance.
Drafted posts sit in a notes app or a scheduler until it's time to post them.
How do you design images or video for a Threads post?
Make visuals that read on a phone: one subject, large text if any, and the same fonts and colours you use on Instagram so your accounts look related.
Easy Reels makes Threads posts in the same editor as its reels, carousels and single images: text alone, or text with images or video. That means a post can reuse a reel you already made, or a few carousel cards, without exporting between apps. Easy Reels edits your own clips and photos; it doesn't generate images or footage.
If you already make reels, a short cut of one is often the easiest Threads video. Cross-posting reels to TikTok and Shorts covers how one vertical video can serve several apps. And on Ultra, the Easy Reels MCP lets Claude or ChatGPT write a video edit from your description and have Easy Reels render it; can Claude edit videos shows how.
Every plan starts with a 14-day free trial with full access; after it, Pro is $19 a month and Ultra $39, and you're never charged if you cancel before it ends. There's no free plan. See the pricing section.
Common questions
Is there a free Threads post generator?
Claude and ChatGPT both have free tiers that can draft Threads posts from your notes. Easy Reels has a 14-day free trial but no free plan.
How long can a Threads post be?
Up to 500 characters of text. Video can be up to 5 minutes.
Should Threads posts have images?
When the image shows something the text can't: a product, a result, a screenshot. Text-only posts are normal on Threads, so don't add a picture just to have one.
Can I post the same content on Threads and Instagram?
Yes, but adapt it. A reel or carousel can go on Threads, with text written for Threads rather than an Instagram caption pasted in.
