Questions? We've Got Answers.

Yes! Boundless learns from your existing posts, captures your unique phrases and patterns, and even remembers words you never use. Every generated post goes through your approval queue, and your feedback continuously improves the AI's understanding of your voice.
When you review posts in the approval queue, you rate them: 'Nailed it,' 'Good,' 'Off,' or 'Reject.' Posts rated highly become training examples for future generation. Over time, Boundless learns exactly how you write - your sentence structure, vocabulary, and even your sense of humor.
The Agency plan supports up to 5 X accounts with separate voice profiles for each. Perfect for agencies managing multiple clients or founders with personal and business accounts.
Your data is yours. We never sell or share your content. All posts are stored securely and you can export or delete everything at any time. We use your content only to improve your personal AI model - never to train general models.
ChatGPT is a general-purpose AI. Boundless is purpose-built for X growth with your authentic voice. We include X algorithm optimization, smart timing, batch generation, approval workflows, and analytics - all trained specifically on your writing style. Plus, we actively filter out AI-sounding phrases.
Absolutely. No contracts, no commitments. Cancel with one click and keep access until the end of your billing period. We'll even let you export all your content and voice profile data.
