Three steps, about fifteen seconds.

No account setup before you can try it, no connecting a broker, no pasting a ticker. It reads the picture you give it.

1

Screenshot any chart

TradingView, your broker app, Webull, MetaTrader - whatever you already use. Keep the price axis and the timeframe in frame and you are done.

2

Get a structured read

Trend and structure, the levels that have actually been tested, named patterns, your visible indicators, and a plain-language summary - always in the same order.

Ask follow-up questions

Anything you want clarified about that specific chart, in a thread attached to the read. Tap a suggested question or type your own.


What a read looks like.

Every analysis comes back in the same shape, so two charts are actually comparable - which is most of what makes a read useful.

Everything it reads off the chart.

The same checklist a technician runs on a first pass, applied identically every time - at 6am, at 11pm, after a winning week and after a losing one.

Trend and structure

The sequence of higher highs and higher lows, or lower highs and lower lows, and the exact point where that sequence broke.

Support and resistance

The price zones that have actually been tested more than once, described by where they formed rather than a bare number.

Chart and candlestick patterns

Triangles, flags, wedges, head and shoulders, double tops, engulfing candles - named, and marked complete or still forming.

Your indicators

Whatever is visible in the screenshot gets read - RSI, MACD, moving averages, volume - rather than assumed defaults.

An honest confidence level

How clearly the chart could be read. A clean daily scores high; a cropped, low-resolution capture scores low, and says so.

"What I couldn't see"

An explicit list of what was cropped out or unreadable, so you know where the read is thin instead of guessing.

Per-chart conversation

Follow-up questions in a thread tied to that specific analysis, so context carries between questions.

Earlier reads, kept

Previous analyses of the same asset stay with it, so you can see how your read of it has changed over time.


What ChartCheck does not do.

Most apps in this category are vague here. Being specific about the limits is more useful than a longer feature list, because you can calibrate around known limits.

It reads a picture. That has hard boundaries.

  • It does not tell you what to buy or sell, and it is not financial advice.
  • It cannot see anything outside the screenshot - not the level from six months ago, not the higher timeframe.
  • It has no order book, no fundamentals and no news. A gap on an earnings miss and a gap on a sector rotation look identical.
  • It does not predict price. Technical analysis describes what already happened, and every pattern fails a meaningful share of the time.
  • Confidence measures how legible the chart was, never the probability that a trade works.

Before you download.

What does ChartCheck actually do?

You give it a screenshot of a price chart and it reads the picture back to you in a fixed structure: trend and market structure, support and resistance zones, chart and candlestick patterns, whatever indicators are visible, a plain-language summary, and a confidence level describing how clearly the chart could be read.

Does ChartCheck tell me what to buy?

No. It describes what a chart shows and it is explicitly not financial advice. It does not recommend buying, selling or holding anything, and it makes no claim about what price will do next.

Which markets does it work on?

Any market whose chart is legible as an image - stocks, ETFs, crypto, forex and futures all work, because they are all candlesticks on an axis. What matters more than the asset is screenshot quality: the price axis and enough bars for context need to be in frame.

Do I need to know technical analysis already?

No, and it is a reasonable way to learn, because every term is attached to a chart you were already looking at. That said, being able to evaluate the output matters - if you cannot tell a good read from a confidently wrong one, you are following something you do not understand.

What does the confidence level mean?

It measures how clearly the chart could be read, not the probability that a trade works. A clean daily chart with a visible price axis scores high; a cropped, low-resolution screenshot scores low. High confidence means the picture was legible, never that price will go up.
