Variants that don't
sound like AI.

Tell us about the post the way you'd describe it to a friend. We generate six per-platform variants — cinematic on Instagram, punchy on TikTok, professional on LinkedIn — each fit to that network's rules and tuned to your voice.

One brief, six native voices.

Generate cinematic on Instagram, punchy on TikTok, professional on LinkedIn — each in the format that platform actually rewards. Streaming output means variants appear as they generate; no spinner-staring.

02Speak normally

No prompt engineering required.

Describe the post the way you'd describe it to a friend. We handle the per-platform translation, the hashtag picking, the character trims, and the LinkedIn-vs-TikTok register shift.

Voice-trained
On your last 50 posts — sentence length, hooks, taboo phrases.
Draft, not final
Every variant is editable. We never auto-publish AI output.
Brand-safe
Forbidden phrases, mandatory disclaimers, tone gates by workspace.
Brief

We're restocking three colours from the spring drop — same hero shot, want it to feel quiet not loud. Make sure people know it's limited.

03Per-platform rules

Knows what each network actually wants.

X cuts you at 280 unless you have Premium. LinkedIn punishes hashtag spam. TikTok puts hashtags inside the caption. Our generator knows these quirks so you never ship a broken version somewhere.

Limit-aware
Trims to the character budget per network; warns before publish.
Hashtag-aware
Picks platform-appropriate tags; strict cap on LinkedIn, broad on TikTok.
Link-aware
Strips raw URLs on X if no card; uses link-in-bio token on Instagram.

04Voice

Trained on your writing, not the internet's.

We sample your last 50 posts and store a tiny voice profile per account — sentence length, emoji usage, opening hooks, taboo phrases. Every generation runs through it so a Pro caption sounds like Pro, not like ChatGPT.

Per-account profile
Different voices for different brands in one workspace.

Inside AI captions

The small things, all in one place.

Six variants. One keystroke.

A short brief in, a per-platform variant out — Instagram, TikTok, X, LinkedIn, Threads, YouTube. ⌘+↵ to generate, ⇥ to cycle.

Hotkey

Hashtag picker.

Suggests platform-appropriate tags from your niche. Strict cap on LinkedIn, broad on TikTok, none on X.

Per-platform

Limit-aware trim.

Auto-fits the character budget per network. Warns before publish if a manual edit pushed it past.

Auto

Variant remix.

Pick two you like, ask for a hybrid. Iterate by direction rather than re-prompting.

Iterate

14-language output.

Same brief, native captions in 14 languages. Localized hashtags per region.

i18n

API + MCP.

Generate captions from your editor or pipeline; MCP exposes the same tools to Claude and Cursor.

  • People expecting AI to write breakout viral hooks for them.
