Penshift is now in your toolbar. Sign in once below and the extension shares your session forever — no API key, no token to copy.
Drag-select text anywhere you write on the web. A small Penshift button appears next to your selection.
Paraphrase (8 modes), humanise, fix grammar, summarise, or detect AI. Right-click works too.
The result drops back into the field you were typing in. Or focus any textarea — a corner button rewrites the whole field in one click.
Pin Penshift to your Chrome toolbar so it's one click away. Click the puzzle icon top-right of Chrome, then the pin next to Penshift.
Four tiers, no usage tricks, no annual lock-in. Free forever for casual writers; verified students get 20% off Pro pricing; Pro at $7.99/mo annual gives you unlimited paraphrasing, humanising, grammar, summaries, translation, and AI detection, plus 25,000 words/month plagiarism.
Long drafts, custom paraphrase instructions, tone matching, plagiarism scanning — the workbench has every tool the extension does, plus the ones that need more screen.
