Refine, simplify, adjust tone, and rewrite content with built-in AI — without leaving your editor or losing your voice.
Eddyter's AI Writing Assistant is built into your editor — refine, simplify, adjust tone, change length, and rewrite content directly inside the document where you write. No tab-switching to ChatGPT. No copy-pasting into Grammarly. No external SaaS subscription.
The full set of AI writing actions live next to your cursor. Highlight any text, pick the action, and watch your content improve while your voice and intent stay intact.
Most AI writing tools have a problem: they're separate apps. You write somewhere, then leave to "improve" the writing somewhere else, then come back and paste the result. The workflow is broken by design.
Eddyter brings the entire AI writing toolkit into the editor. Highlight text and apply any of the following actions in one click:
Each action is purpose-built. Together, they cover the full spectrum of "make this writing better" without the AI flattening your voice into corporate sludge.
The biggest failure mode of AI writing tools is voice flattening. You feed in something interesting and you get back something generic — technically correct but stripped of personality, perspective, and brand voice.
Eddyter's AI Writing Assistant takes a different approach: enhance, don't replace. The AI improves clarity, structure, and readability while preserving:
Result: content that reads like you wrote it, just better.

For SaaS teams shipping editors to their own users, the in-editor option is the only one that scales. Your customers shouldn't need to set up ChatGPT or install a Grammarly extension to write better content in your product.
Dense paragraphs become clear sentences. Jargon becomes plain language. Long structures become readable. Ideal for technical documentation, customer support replies, and any content reaching non-specialist readers. Read more about Simplify.
Shift writing register without rewriting from scratch. Convert formal documentation into approachable explanation; soften an aggressive draft into a measured response; tighten a casual note into a professional update. Read more about Adjust Tone.
Adjust content length intentionally. Pad too-thin drafts with relevant detail; tighten over-long copy without losing key points. Read more about Make Longer / Shorter.
Catch grammar, spelling, and structural errors without rewriting your sentences. A proofreader, not a ghostwriter. Read more about Fix Grammar.
Convert content into 50+ languages while preserving formatting, tone, and technical accuracy. Read more about Translate.
Turn text descriptions into custom visuals inserted inline. Replace stock photo subscriptions and external image tools. Read more about Generate AI Image.
The AI Writing Assistant isn't an add-on, plugin, or third-party integration. It ships with the standard Eddyter editor on AI-enabled plans.
For developers integrating Eddyter into a SaaS app, that means:
