AI content generation in your brand voice
Turn a topic into ready-to-post content in seconds. Optimate generates captions, hooks, hashtags and images tailored to each platform — and because it learns your brand voice, the output sounds like you, not a generic bot.

The blank-caption problem
Staring at an empty box
Coming up with a strong hook and caption from scratch, for every post, is the slowest part of social.
Generic AI that sounds like AI
Most tools spit out bland, robotic copy you have to heavily rewrite before it's usable.
Reformatting for every platform
What works on LinkedIn flops on TikTok — manually adapting each post eats time.
From idea to on-brand post, fast
Give Optimate a topic and it does the heavy lifting — you tweak and post.
Captions, hooks and variations
Get a strong primary caption, a shorter alternative and multiple hook options for every post, tuned to the platform.
Your brand voice, applied automatically
Set tone, audience, keywords and forbidden words once. Every draft respects them — with tone presets like human, story, short or corporate.
Smart hashtags
Generate relevant, platform-appropriate hashtag sets instead of spraying the same tired tags everywhere.
AI images to match
Create visuals generated to fit the post you've written, right inside the composer.
Repurpose across platforms
Take one idea and adapt it into platform-native versions for Instagram, TikTok, X, LinkedIn, Facebook, YouTube, Pinterest and Bluesky.
A more human style
An optional humanising mode avoids the tell-tale AI phrasing, so posts read naturally.

Common questions
Will the content actually sound like my brand?
Yes — set your brand voice, audience, keywords and preferred CTAs once, and every draft is generated to match. You can also give example posts as a style reference.
Which platforms does it write for?
LinkedIn, Instagram, Facebook, X, YouTube, TikTok, Pinterest and Bluesky, with platform-specific formatting for each.
Can I generate images too?
Yes — you can create AI images that match the post you've written, directly in the composer.
Is it free to try?
Free includes 5 AI generations to try. Pro (£29/month, 7-day free trial, or £290/year) unlocks AI for ~1,000 captions or 200 images a month.
