Looking for a Chartby alternative with a structured letter grade?
Chartby (AI Chart Analysis - Chartby) is a screenshot-upload app that turns a chart into a plain-language technical-analysis lesson, explicitly framed as educational, not a trade recommendation. SnapPChart is a screenshot-upload AI grader that returns a structured A+ to F letter grade with a full execution plan, built to inform an actual trade decision, starting with 2 free lifetime analyses. Compare the two before you pick one.
Quick answer
Both read an uploaded chart screenshot. The real difference is a technical-analysis lesson vs a structured letter grade meant to decide a trade.
Chartby, AI Chart Analysis - Chartby (App Store id 6739337782, developer Pixoby OU, chartby.app), is, like SnapPChart, a screenshot-upload AI tool with no broker or account connection. Its own App Store listing describes the output: a sample trade setup (entry, stop-loss, and target zones "so you can see how a plan is structured"), automatic support/resistance and trend direction, candlestick and classic chart-pattern detection (head and shoulders, triangles, flags), plain-language RSI/MACD/momentum reads, a risk level with risk/reward and an AI confidence score, a market-sentiment outlook, and an AI chat feature to ask follow-up questions about the chart. Critically, Chartby's own listing states it twice: it is "an educational tool for learning technical analysis," the trade setup shown is explicitly a sample "so you can see how a plan is structured," and the app "does not provide financial advice, and nothing in the app is a recommendation to buy or sell any asset." It covers stocks, crypto, forex, indices, and commodities, is free to download with in-app purchases (exact tier pricing not independently confirmed at build time), was released December 2024, and carries a 4.65-star average from 17 App Store ratings as of its July 2026 update (version 4.0.8). What it doesn't offer: a letter grade, a multi-target exit plan, trailing-stop guidance, a dedicated bear case, an alternative entry, or a position-size calculator, the fields SnapPChart adds to every grade. SnapPChart works the same way on input, screenshot only, no broker or data-feed connection, and is positioned differently: every grade is meant to help you decide whether to take the specific trade in front of you, not to teach you to read charts generally. It discloses stocks, forex, crypto, futures, and indices, adds a letter grade, entry, stop, multi-target exits (T1 partial, T2 full), trailing-stop guidance, a bear case, an alternative entry, and a position-size calculator, on top of a free tier you can actually use: 2 free lifetime analyses (the first full, the second gated) before any card is required.

A Structured Grade, Built To Decide The Trade
A Letter Grade Instead Of A Lesson
Chartby's own listing frames its trade setup as a sample "so you can see how a plan is structured," and states twice that it does not provide financial advice. Every SnapPChart grade opens with a structured A+ to F letter grade meant to inform the specific trade in front of you.
Every Grade Adds A Fuller Execution Plan
Chartby's listing doesn't mention a multi-target exit plan, trailing-stop guidance, a bear case, an alternative entry, or a position-size calculator. SnapPChart adds all five to every grade, on top of entry and stop.
Its Edge: A Teaching Layer With AI Chat
Chartby explains RSI, MACD, and chart patterns in plain language and lets you ask an AI chat follow-up questions about the chart, a learning-focused layer SnapPChart doesn't itemize the same way.
Chartby Alternative FAQ
Is SnapPChart a Chartby replacement?
For the core job, uploading a chart screenshot and getting an AI read, yes. Chartby's own listing frames itself as an educational tool for learning technical analysis, with a sample trade setup and an explicit statement that it is not financial advice. SnapPChart's edge is a structured A+ to F letter grade with a full execution plan, entry, stop, multi-target exits, trailing-stop guidance, a bear case, and an alternative entry, built to help decide the specific trade you're looking at.
Does Chartby give a letter grade like SnapPChart?
No. Chartby's own App Store listing describes a structured technical-analysis breakdown, trend, levels, patterns, indicators, a risk check with a confidence score, and a sentiment outlook; no letter grade or A-to-F scale is named anywhere in the listing. SnapPChart opens every grade with a structured A+ to F letter grade.
Is Chartby's trade setup meant to be acted on?
Per its own App Store listing, no. Chartby describes the entry, stop-loss, and target zones it shows as a sample "so you can see how a plan is structured," and states directly, twice, that it is an educational tool and does not provide financial advice or a recommendation to buy or sell. SnapPChart's grade, entry, stop, and targets are built to help you decide the actual trade you're considering.
What assets does Chartby cover?
Its App Store listing names stocks, crypto, forex, indices, and commodities. SnapPChart discloses stocks, forex, crypto, futures, and indices.
How does pricing compare?
Chartby is free to download with in-app purchases; its App Store listing does not disclose exact tier pricing. SnapPChart starts with 2 free lifetime analyses (the first full, the second gated), then paid plans up to Yearly at $199.99/yr (about $16.67/mo) for unlimited grades.
Can I use both tools?
Yes. Use Chartby when you want a plain-language technical-analysis lesson and an AI chat to ask follow-up questions about a chart. Use SnapPChart when you want a structured letter grade with a fuller execution plan on that same setup, entry, stop, multi-target exits, trailing-stop guidance, a bear case, and an alternative entry, built to help you decide the trade.
