Tips
- Instagram allows 5 hashtags per post. More than that and the post may not go through.
- Threads allows one topic tag per post.
- On YouTube, up to 3 hashtags show by the title, and a video with more than 60 loses them all.
- A few specific tags beat a long list of huge ones.

FAQ
Common questions
Is it really free?
Yes. You can use the AI tools 10 times an hour and 25 times a day in total, without signing up. The limit keeps them free for everyone.
Which AI writes this, and do you keep what I type?
It runs on a DeepSeek model through OpenRouter, sent only to providers that keep no copy and don't train on it. We don't store or log what you type. To enforce the free limit we keep a counter tied to a scrambled version of your IP address, and it's deleted within 2 days. Details are in our Privacy Policy.
Can I post these with tenfeeds?
Not yet. tenfeeds is opening platforms one at a time. Join the waitlist and we'll email you when yours open.
