Chartself is a trading journal built for traders who want more than a log of their trades. It uses AI to catch the specific habits quietly costing money, revenge trading after a loss, performance leaks tied to certain times of day, risk rules broken under pressure, and attaches a real dollar cost to each one, not just a stat. Traders can sync trades automatically from a growing list of supported brokers or import via CSV, and ask questions about their own trading history through an AI chat feature that runs on the user's own API key, so trade data never trains a shared model. The core journaling experience, unlimited trades, dashboard, calendar, equity curve - is free.
ForthWrite is an AI email writing assistant for Gmail and Outlook that learns your writing style from your real sent mail. The more you use it, the more it sounds like you. Get smart drafts in seconds, auto-draft replies before you open your inbox, and maintain your personal voice at scale. Free to start, no credit card required. Works inside Gmail and Outlook on the web.
How it works
ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.
Key features
Who uses it
Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.
Pricing
Free tier includes 10 drafts per week with no credit card required. Paid plans start at $12/month and include unlimited drafts, custom persona prompts, and auto-draft.

Chartself's answer
Chartself doesn't just log your trades. It uses AI to catch the specific habits quietly costing you money: revenge trading after a loss, performance leaks tied to certain times of day, risk rules broken under pressure. Each pattern comes with the actual dollar cost attached, not just a stat. It also runs AI insights on your own API key, so your trade data never trains a shared model.
ForthWrite's answer:
ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.
Chartself's answer
Most trading journals show you what happened. Chartself tells you what it's costing you and why it keeps happening. Unlimited trade journaling is free (not a time-limited trial), it syncs automatically from a growing list of supported brokers, and the AI runs on your own key rather than a shared model.
ForthWrite's answer:
Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.
Chartself's answer
Beginner and early-stage traders who are still building discipline and want to understand why their trades keep going wrong, not just track that they happened. Chartself's free tier and AI-driven pattern detection make it easy to start building good habits from day one, without needing to already know what to look for in your own trading data.
ForthWrite's answer:
Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.
Chartself's answer
Chartself started from my own trading losses. Like a lot of traders, the same costly habits kept repeating: revenge trading after a bad loss, blowing past risk rules in the heat of the moment, trading worse at certain times of day without realizing it. Manually digging through spreadsheets never made the pattern obvious until the damage was already done. Chartself was built to catch those patterns automatically and put a real dollar figure on them, so traders can see the cost before it repeats again.
ForthWrite's answer:
Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.
Chartself's answer
Chartself just launched, so we're focused on onboarding our first users right now rather than naming customers.
I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.
The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.
What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.
The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.
Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.
ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.
Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.
