Propel Software connects product lifecycle management (PLM), product information management (PIM), and quality management (QMS) on a single cloud-native platform, unifying teams, processes, and information with a continuous product thread and embedded collaboration from concept to customer. Recognized as a Deloitte Technology Fast 500 winner and one of Fortuneโs Most Innovative Companies in America, Propel is built on Salesforce and drives product success for hypergrowth startups and corporate pioneers in the high-tech, medtech, and consumer goods industries.
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.

Propel's answer
Propel's answer
Propel is built on Salesforce to help companies efficiently connect product and commercial data. By being built on the world's most secure CRM system, product companies can focus less on securing product data and learning a complicated user interface, and focus more on launching new products faster, increasing company-wide collaboration, and dominating their market with winning products.
Note: You don't have to be a Salesforce user to use Propel.
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.
Propel's answer
Discrete manufacturers primarily in the Med Tech, High Tech, Industrial, and Consumer Goods spaces. Product companies that struggle with connecting their product and commercial teams and need a solution to bring new products to market faster, address quality issues by ensuring customer feedback reaches product teams, and need to enrich their product data with the most accurate and up-to-date information. We serve Startups, SMBs, and Enterprise companies.
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.
Propel's answer
We are a modern, Cloud-based, future-focused solution that helps you scale easily as your business grows. Our competitors are mostly legacy systems built over 30 years ago that don't understand the needs of today's product companies. Some competitors are still On-Prem, while others have shifted from On-Prem to Cloud and haven't truly lost On-Prem headaches such as the difficulty to collaborate effectively, organize vital product data and make sense of it, generate reports, etc. Combine that with soaring costs for upgrades and maintenance and you're headed for a disaster.
Propel was built in the Cloud from the start (since 2015) and we have three new releases every year to ensure our PLM, QMS, and PIM is up-to-date with features that customers want to see. On top of that, we ensure all product data is connected, from product lifecycle management data to quality data to product information management. We also offer the ability to manage suppliers securely, BOM, CAPAs, CAD integrations, and much more.
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.
Propel's answer
Our founders came from Oracle Agile, so our product feels very familiar to Oracle Agile but without the crowded interface and inefficiencies of Agile PLM. Propel was founded in 2015 with the vision to help product companies innovate faster by collaborating in a more efficient manner.
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.
ForthWrite's answer:
Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API
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.
