textcortex is a browser extension that adds ai writing features to every text box on the web. gmail, google docs, notion, wordpress — wherever you type, textcortex can help.

the convenience is real. the rewriting depth is not.

what textcortex offers

a browser extension with generation, rewriting, summarization, and translation. it works inline wherever you write. they also have templates, a knowledge base feature, and a standalone editor.

the breadth is impressive. you can use it in dozens of contexts without leaving your current tool.

the shallow rewriting problem

textcortex's paraphrasing is surface-level. it swaps words and rearranges clauses. the output is slightly different from the input but the underlying patterns — sentence rhythm, vocabulary distribution, structural predictability — barely change.

run textcortex-rewritten text through a strict detector like originality.ai and you'll see. the score drops from raw ai levels but lands in the 40-60% range. still flagged.

browser extensions have compute constraints. they can't run the heavy models that deep rewriting requires. the trade-off for being everywhere is being shallow everywhere.

paraai's depth advantage

paraai's paraphrase runs fine-tuned models trained on human-text corpora on our servers. no compute constraints. the model reads the full passage, understands the meaning, and regenerates text with genuine human writing patterns.

the output consistently scores under 10% on every major detector. because the rewriting is deep — structural, not surface-level.

the trade-off

textcortex: available everywhere, shallow rewriting. paraai: available in our workspace, deep rewriting.

if you need quick ai assistance in 50 different apps and detection doesn't matter, textcortex's convenience wins.

if you need untraceable ai writing that genuinely passes detectors, paraai's depth wins. you can always paste text from anywhere into paraai for the final rewriting step.

using both

some people use textcortex for quick generation across their tools, then paste important pieces into paraai's paraphrase. convenience for casual writing, depth for writing that matters.

that's a reasonable workflow. the key is knowing which writing needs the deep treatment and which doesn't.
