How it works
Paste your text
Drop in a tweet, caption, blog intro, or any content between 70 and 2,000 characters. The editor already supports bold, italic, links, mentions, and hashtags.
Choose the right check
Use the hero quick actions for common tasks, then run the full TextScore analyzer when you need readability, spam, sentiment, link, and content-risk feedback in one pass.
Fix issues before you post
Read the score, check the metric cards, and follow the plain-language guidance before you publish to X, Medium, Discord, or anywhere else online.
Why TextScore is the flagship check
When a quick count is not enough, TextScore combines readability, spam risk, sentiment, link safety, content risk, professionalism, passive voice, complexity, and conditional AI review in one workflow.
Readability
Flesch Reading Ease and Grade Level show whether your audience can read what you wrote and how difficult the draft feels.
Content Quality Score
A composite 0-to-100 number combines readability, sentiment, professionalism, topic cohesion, and penalties for risky patterns.
Spam Risk Detection
Capitalization ratio, excessive punctuation, and forbidden keyword scans catch the patterns that cost distribution.
Sentiment Analysis
VADER compound scoring rates the emotional tone of your copy so you can avoid overly extreme drafts.
Link Safety
Shorteners, suspicious TLDs, homograph attacks, embedded credentials, and IP-based URLs are all flagged.
Content Risk Scoring
Urgency phrases, suspicious phrases, memecoin hype, and unrealistic promises are checked against the live rule set.
Language Professionalism
Mild, moderate, and strong informal language signals help you tighten copy without losing your voice.
Passive Voice and Complexity
Passive voice count and complex sentence detection help you find the parts of a draft that drag.
AI-Powered Assessment
When local risk is high enough, the AI layer adds qualitative feedback, rewrite suggestions, and a shadowban-risk view.

Prove You Wrote It. Before Anyone Else Claims It.
TextProof creates a tamper-proof timestamp for your writing using the Bitcoin blockchain. You paste your text, the browser computes a fingerprint, and OpenTimestamps anchors it to a Bitcoin block. Your text never leaves your device. You get a downloadable proof file you can use to verify authorship anytime.
- Client-side fingerprinting - Your text is hashed in the browser using SHA-256. The raw text never touches a server.
- Bitcoin-anchored timestamps - OpenTimestamps submits your fingerprint to multiple calendar servers and anchors it to a Bitcoin block.
- Downloadable proof file - You receive an .ots proof file that anyone can independently verify against the Bitcoin blockchain.
Why your writing quality controls your reach
Every major platform runs content through ranking algorithms before showing it to anyone. Poor writing quality is one of the fastest ways to get suppressed without ever being told. TextScore catches the signals these algorithms look for.
X (Twitter)
X's algorithm de-prioritizes posts with excessive caps, spam-trigger words, and shortened URLs. A single flagged link can tank an otherwise strong tweet. TextScore checks your capitalization ratio, forbidden keywords, and every link for shortener domains, suspicious TLDs, and homograph attacks - all signals X uses to decide if your post gets surfaced or buried.
Facebook and Instagram
Meta's content distribution system penalizes engagement bait, urgency language, and exaggerated promises. Phrases like "act now" or "you won't believe" are pattern-matched against known suppression lists. TextScore's content risk analyzer scans your text against 245+ flagged phrases across four risk categories - urgency, suspicious, memecoin hype, and unrealistic promises - so you know exactly what to rewrite.
LinkedIn's feed algorithm rewards professional tone and readable structure. Posts with excessive punctuation, informal language, or overly complex sentences get less distribution. TextScore evaluates language professionalism across three severity tiers, flags passive voice and sentence complexity, and gives you a Flesch readability score so your posts match what LinkedIn's algorithm prefers to surface in professional feeds.
Medium
Medium's curation algorithm favors well-structured, readable articles over keyword-stuffed or clickbait content. Low readability scores and high spam signals push your article out of topic feeds and recommendations. TextScore gives you a composite content quality score from 0 to 100 that combines readability, sentiment, keyword density, and topic cohesion - the same dimensions Medium's system evaluates when deciding distribution.
Discord
Discord community managers deal with a flood of spam, phishing links, and low-effort content. AutoMod and community-built bots flag messages with suspicious URLs, all-caps text, and repeated punctuation. TextScore's link safety analyzer and spam detection catch the exact patterns these systems watch for, letting you pre-screen announcements and pinned messages before they hit a channel.
Email and newsletters
Email providers use content scoring to route messages to inbox, promotions, or spam. Subject lines and body text with spam trigger words, excessive caps, or aggressive sentiment get filtered before your reader ever sees them. TextScore's forbidden keyword scanner, capitalization ratio check, and sentiment analysis map directly to the heuristics Gmail, Outlook, and Yahoo use for inbox placement decisions.

Frequently asked questions
What does TextScore analyze?
TextScore runs 12 checks on your text: readability, spam risk, sentiment, link safety, content risk, professionalism, passive voice count, complex sentence detection, and an overall content quality score. When local risk is high enough, an AI-powered assessment adds qualitative feedback and rewrite suggestions.
Which platforms does TextScore support?
TextScore supports platform-specific analysis for X, Medium, and Discord, with a General fallback that also covers other publishing surfaces.
Is my text stored or shared with anyone?
TextScore caches analysis results temporarily to speed up repeat checks on the same text. Your text is not sold or used for advertising. When AI analysis triggers, your text is sent to OpenAI for evaluation. Read the privacy page for the full policy.
Is TextScore free?
Yes. TextScore is free to use. A daily rate limit per IP address exists to prevent abuse, but normal usage is not affected.
What are TextTools?
TextTools is a free suite of 11 browser-based text utilities built into TextScore.io. It includes a word counter, case converter, text cleaner, find and replace, line sorter, deduplicator, lorem ipsum generator, slug generator, markdown preview, encoder and decoder, and text extractor. Every tool runs entirely in your browser - your text is never sent to a server. There is no signup, no account, and no tracking. You can use TextTools independently of the TextScore analyzer.
What is TextProof and how does it work?
TextProof is a free content timestamping tool that creates a tamper-proof record of when you wrote something. When you paste your text, the browser computes a SHA-256 fingerprint without sending the text to any server. That fingerprint is then submitted to OpenTimestamps calendar servers, which anchor it to the Bitcoin blockchain. You receive a downloadable .ots proof file. Later, you or anyone else can verify the proof by providing the original text and the proof file - the system confirms whether the fingerprint matches and when it was timestamped. TextProof is useful for establishing prior authorship, timestamping drafts, and protecting original content.
