A grade for your content, before you hit post.
Synthiya is an AI content-scoring tool that grades social media posts before you publish them. It analyzes your caption, hook, hashtags, timing and creative against 312 factors across 13 categories, then returns a 0–100 score with specific fixes. The first score is free, with no signup.
Most creators post, wait, and hope. The ones who grow treat every post like a draft that can be improved first. Synthiya is that second pair of eyes — one that has a rubric instead of a mood.

Fair questions.
What is Synthiya?
Synthiya is an AI content-scoring tool that grades social media posts before you publish them. It analyzes your caption, hook, hashtags, timing and creative against 312 factors across 13 categories, then returns a 0–100 score with specific fixes. The first score is free, with no signup.
What is an AI content score?
An AI content score is a 0–100 rating that predicts how well a post is likely to perform, based on measurable factors: hook strength, caption structure, hashtag quality, call-to-action placement, posting time and more. Synthiya's version checks 312 such factors and shows you a sub-score for each of 13 categories.
Is Synthiya free?
Your first score is completely free — no signup. A free account gets limited daily scores. Premium unlocks all 16 tools at ₹299/month, ₹1,999/year (about ₹167/month), or ₹4,999 once for lifetime access.
What are the 312 factors?
They span 13 categories: hook strength, caption readability, emotional pull, hashtag relevance, CTA clarity, posting time, platform format fit, trend alignment, shareability and more. Each category gets its own sub-score, so you can see exactly where a post is weak instead of guessing.
Which platforms does Synthiya support?
Instagram (posts, reels, stories), X (Twitter), LinkedIn, YouTube and Reddit. You choose the platform and format before scoring, so the rubric matches that platform's rules — a great tweet and a great reel caption are scored very differently.
How is this different from asking ChatGPT?
A chatbot gives you an opinion that changes every time you ask. Synthiya runs a fixed 312-factor rubric tuned per platform, gives consistent 0–100 scores you can compare across drafts, and adds tools a chat window doesn't have: Profile Audit, Ad Creative Analysis, Score Battle, and a 30-day calendar.
What is Roast Mode?
Comedy feedback. Instead of a polite score, Roast Mode roasts your post in Hinglish like a brutally honest friend, then gives you the fix. Roasts come as story-ready cards — half our users share them and tag the friend who needed to see it.
Does Synthiya post anything to my accounts?
No. Synthiya never connects to your social accounts and never posts anything. It only reads the draft you paste in, scores it, and hands it back with fixes.
Can I cancel anytime?
Yes. Monthly plans cancel anytime and you keep access until the billing period ends. Lifetime is a single payment — there's nothing to cancel.
Built in India, by two creators who got tired of guessing.
One sharp tip a week.
What we learn from scoring thousands of posts — the hooks, timings and formats that actually move numbers. No spam, unsubscribe whenever.
Your next post deserves a score above 80.
