Everything you need to sound like you.
From your existing posts to long-form video, Postia turns what you have into on-brand social content, in Welsh, English, or both.
Recreate what you already post
- Upload a post you already love and Postia rebuilds it as a live, editable asset.
- Switch between Welsh and English in a click.
- Resize the canvas for any platform.
- Ask it to add movement, then export the finished assets locally.
Turn long-form video into social
- Upload a long-form video and Postia generates the captions automatically.
- Already have subtitles? Upload the .srt or .vtt and your timings are kept.
- It suggests the social clips worth cutting, and captions sit on the timeline where you can edit them.
- Cut once, deliver everywhere: each platform output keeps its own framing from one master edit.
- Export captions as SRT, or pick a style and burn them straight into the video.
- All bilingual, and all yours to approve.
Get your Welsh checked by a human
On any caption or graphic, ask a qualified language professional to review it before you publish. You send it, they verify it, you approve it. A real human on the Welsh, not just the AI.
Dynamic stills and graphics
Posts, quotes, quizzes, polls, designed not defaulted. Postia does the layout, rendered to your brand.
It knows your brand
Store your colours, fonts, logo and voice once. Every asset is built from the brand facts you approve, so captions and copy sound like your organisation, not like anyone else.
Welsh and English, first-class
Both languages treated as equals, not a translation bolt-on. Switch or pair them per asset, the Welsh reads like Welsh, and a Welsh brand fact is only used once a Welsh speaker has reviewed it.
Accessible by default
Burn captions into your video so it works with the sound off, and add alt text on export. The accessible thing to do, and the compliant one for public-sector feeds.
An assistant in the editor
Right where you work, ask it to rewrite a line, tighten a caption, draft caption and hashtags, or critique a post before it goes out. You take what helps and leave the rest.
You stay in control
Nothing publishes on its own. A person approves every image, video and caption, and your brand data stays yours.
