Sely — AI Actions

Sely — AI actions on any text you select. Explain, improve, summarize, ask anything. Free or BYOK.

Stop copy-pasting into chatbots. Sely puts AI exactly where your text already is. Select anything -- a paragraph you're reading, a sentence you're drafting, an email you're dreading -- and a small action bar appears right beneath it. One click, and the answer streams back in place. No tabs, no context-switching, no workflow broken. TWO MODES, ZERO FRICTION Reading something? Explain, Summarize, or Translate it -- the answer streams into a floating card with word-by-word animation, ready to copy. Writing something? Improve, Shorten, change the Tone, fix Grammar, or Proofread -- your own words rewrite live, inline, with Keep / Discard / Retry. Nothing is permanent until you say so. And "Ask anything" is always there: type any instruction or question about your selection, from "make this sound confident" to "what does this clause actually mean?" MADE FOR HOW YOU WORK • Context-aware: editing tools appear in text fields; reading tools appear on articles. Never the wrong buttons. • Draggable bar: grab the grip and put it where you want it. • Per-site mute: silence Sely on sites where you never want it, right from the bar. • Custom actions: bottle your own prompts (Elaborate, Simplify, Formalize, Anything…) with an AI prompt-writer built into Settings. • Selection cap you control, up to your plan's ceiling. Long reads truncate gracefully with a notice. FREE OR YOUR OWN KEY Sely Free: sign in with Google and go. A generous 5-hour + weekly quota with a clear usage meter, so you always know where you stand. BYOK: bring any OpenAI-compatible key and run unlimited. Keys live only on your device -- never synced in plain text, never touching our servers (requests go straight from the extension to your provider). PRIVATE BY ARCHITECTURE No analytics. No telemetry. No conversation history. The interface renders in isolated Shadow DOM that pages can't touch, and the privacy policy is one page because there's almost nothing to disclose. Perfect for writers tightening drafts, students working through papers, developers deciphering docs, and anyone who's ever thought "I wish AI could just do this sentence." Install Sely. Select text. Done.
