Write faster. Think deeper. Ship smarter.
The AI assistant that helps you write a social launch thread
Everything you need
Built for the way teams actually work
Everything a modern writing team needs - from the first draft to the final ship.
Drafts in seconds, not hours
Aria writes a full first draft in under thirty seconds - emails, docs, landing copy, release notes - so the slow part of writing stops being the typing.
Built-in privacy
Encrypted at rest and in transit. Your content never trains shared models. Continuous monitoring, audit-ready logging, and data-residency options across EU and US regions on Enterprise.
Wired into your stack
Native integrations for docs, knowledge bases, chat, and issue trackers - plus a REST API, webhooks, and a browser extension that puts the assistant inside any text field.
Context-aware AI
Aria reads the document you're in, the documents you cite, and the brand profile you've trained - then writes the way your team actually writes, not the way an LLM thinks you should.
Real-time, multi-author
Live cursors, threaded suggestions, and AI feedback that respects who's writing what. Works the way collaborative docs work - minus the chat bot pretending to be an assistant.
Test what wins
Generate variants, ship them as A/B tests through your existing tools, and feed the winner back into your brand profile. The model gets sharper with every campaign.
API-first
One streaming endpoint covers drafting, rewriting, summarising, and tone-shifting. SDKs for TypeScript, Python, and Go. Rate limits scale with plan tier.
Twelve languages, one voice
Generate content in twelve supported languages with the same brand profile applied across all of them. Your French release notes sound like the team that wrote your English ones.

40+ integrations

How it works
Three steps to better writing.
Connect your tools
Connect your workspace
Link the docs, knowledge bases, and chat tools your team already uses. Setup takes under five minutes - no engineering required.
Brand Voice
Set your brand voice
Aria reads a handful of your best documents and builds a voice profile your whole team writes from. Editable any time as your brand evolves.
Write with confidence
Draft, rewrite, and review inside your existing editor. Every suggestion comes with a voice-match score so you ship copy that sounds like you, not like AI.
