Hot take: most founders don't have a product problem, they have a distribution problem. You can't out-build silence.

[ how it works ]
From scroll to posted
in four steps
01
Read
Charply lives inside the feed. It reads the post you're on — caption, author, thread — no copy-paste, no tab switching.
02
Understand
Before drafting, it pulls the top comments on the post so replies match the actual conversation, not just the caption.
03
Draft
Three options in your voice — tone, length, and language matched to the post. Never generic AI sludge.
04
Post
One tap to post, or let the agent run inside hourly and daily caps you set. Every reply is logged and reviewable.
[ the product ]
Everything you need to draft,
curate, and automate
Reply Assistant, Library, Trends, and a guarded Agent — coordinated by global rate limits, not hidden timers. All where posts actually live.
No more tab dance
Drafts in seconds. Charply reads the post and returns three options in your voice — right inside the feed, no copy-paste.

Actions. Scan, read the room, draft, match tone, post, skip ads — on X, LinkedIn, Instagram, and TikTok.
[ safe by design ]
We handle the hard stuff
Engagement automation fails in boring, predictable ways. Charply ships the unglamorous engineering that keeps your account safe and your replies human.
Ad & sponsored detection
Promoted posts, paid partnerships, and shop CTAs are recognized and skipped — your replies only land on organic posts.
One reply per post, ever
Durable deduplication survives refreshes, retries, and restarts. No double-comments, no obvious bot tells.
Language that matches the post
Reply language is pinned to the post itself — dominant-script detection means an English post never gets a surprise reply in another language.
Global rate caps
Hourly and daily limits coordinate across every window and platform. Two agents can never combine past your ceiling.
Assist mode
On LinkedIn, drafts queue for your approval before anything sends. Human-in-the-loop is one toggle away on every platform.
We chase platform changes
Feeds change their DOM weekly. We ship the fixes so your workflow never notices — that's the whole point of a managed extension.
[ by the numbers ]
Engagement at the speed and scale of social.
[ secure by design ]
[ platforms ]
One extension.
Four feeds.
Zero tab juggling.
Every platform shares the same primitives — drafts, library, agent, caps — but gets platform-accurate behavior. Per-window agents stay independent while global limits coordinate across all of them.
X / Twitter
Replies, trends scanning, viral surfaces, fast-cadence engagement.
Comment drafts with assist mode, feed hygiene, careful pacing defaults.
Reads caption and top comments before drafting. Posts through Instagram's own composer flow.
TikTok
Reads the comment panel on media-first posts so replies match the audience, not just the caption.

“Finally an extension that stays in the tab. I generate, tweak once, and post — the library keeps my best objection handlers a click away.”

“Assist mode on LinkedIn saved us from surprise sends. The agent feels controlled — not spammy. Our brand voice survived going from 8 replies a day to 40.”

“Trends + side panel means I draft into the moment without opening five tools. I haven't pasted into ChatGPT in months.”

Frequently asked
questions
Anything else? Write to us and a human replies — fittingly — fast.
Which platforms does Charply support?
X (Twitter), LinkedIn, Instagram, and TikTok — all inside one Chrome extension. Each platform gets platform-accurate behavior: trends on X, assist-mode drafts on LinkedIn, comment-aware replies on Instagram and TikTok.
Will my replies sound like AI?
Charply drafts from the actual post and its top comments, in your trained voice, with tone and length controls. Multi-layer filters block hollow agreement, vague questions, and classic AI tells before anything reaches the feed.
Is the agent safe for my account?
The agent ships with conservative defaults: global hourly and daily caps, single-reply-per-post deduplication, ad and sponsored-post skipping, human-like pacing, and an automation-risk circuit breaker that pauses before anything looks robotic.
Can I review replies before they post?
Yes. Assist mode queues every draft for your approval — on by default for LinkedIn, available everywhere. You can also run fully manual from the side panel and never enable the agent at all.
Does the agent keep running if I switch tabs?
The agent needs its tab visible to read the feed, so switching away in the same window pauses it — Chrome throttles background tabs by design, and we don't fight that. To run more than one agent at once, open each platform in its own Chrome window instead of a background tab; every window you run still shares one set of hourly and daily caps, so you're never at extra risk by adding more.
Do I need API keys or a developer setup?
No. Install the extension, sign in, and you're drafting replies on the post you're already reading. There's nothing to configure unless you want to tune the agent.
What does it cost?
There's a free tier to start, and paid plans scale by monthly reply volume. Upgrade, downgrade, or cancel any time from the billing dashboard.
