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

  • Auto-draft: replies waiting in Gmail before you open your inbox
  • Voice matching from your real sent mail, not templates
  • Recipient-aware drafts that adapt to who you are emailing
  • Prompt Lab for version-controlling and A/B testing your persona prompt
  • BYOK support: bring your own API key for Claude, OpenAI, Grok, Mistral, and more
  • Works in Gmail and Outlook on the web, plus a standalone browser widget
  • Training data export and full data portability

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.

  • Access to Credit for SMEs
    Onsurity Edge provides small and medium enterprises (SMEs) with access to credit lines that can help manage cash flow and fund employee healthcare benefits, which may otherwise be difficult for smaller businesses to afford upfront.
  • Integrated with Employee Benefits
    The credit program is tightly integrated with Onsurity's employee healthcare and benefits platform, making it convenient for businesses that already use or plan to use Onsurity's health benefits ecosystem.
  • Quick and Simple Application Process
    The program is designed for a streamlined digital application and approval process, reducing the paperwork and time typically associated with traditional business credit or loan applications.
  • Flexible Repayment Options
    Onsurity Edge offers flexible repayment terms, allowing businesses to manage their finances more effectively by spreading out costs over time rather than making large lump-sum payments.
  • No Collateral Required
    The credit program is typically unsecured, meaning SMEs do not need to pledge assets or collateral to access the credit line, lowering the barrier to entry for smaller businesses.

Possible disadvantages of Onsurity

  • Limited Availability
    Onsurity's services may be limited to certain regions or geographies, potentially restricting access for companies or employees situated in areas not covered by their network.
  • New Market Player
    Being a relatively new player in the insurance space, Onsurity may not have the same level of recognition or trust compared to well-established insurance providers.
  • Coverage Restrictions
    Some plans may have limitations or exclusions on coverage for pre-existing conditions or specific treatments, which could affect the suitability for certain employees.
  • Scalability Challenges
    While suitable for small to medium enterprises, there could be challenges in scalability or meeting the needs of very large organizations or diverse employee bases.
  • Limited to Onsurity Ecosystem
    The credit obtained through Onsurity Edge is generally tied to spending within Onsurity's own products and services, limiting how businesses can use the funds compared to a general-purpose business credit line.
  • Eligibility Restrictions
    Not all businesses may qualify for the program, as eligibility criteria such as company size, revenue, and credit history may exclude newer or very small businesses that could benefit most.
  • Interest and Fees May Apply
    Like any credit product, Onsurity Edge may come with interest charges or processing fees that add to the overall cost of employee benefits, potentially making it more expensive than paying upfront.
  • Limited Public Information on Terms
    Detailed terms, interest rates, and conditions of the credit program are not always fully transparent on the website, requiring businesses to engage with sales representatives to understand the full cost structure.
  • Dependency on a Single Provider
    Relying on Onsurity for both benefits and credit creates a dependency on a single vendor, which could be risky if the company changes its terms, raises prices, or experiences service disruptions.

Questions & Answers

As answered by people managing Onsurity and ForthWrite.

Which are the primary technologies used for building your product?

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

    ยท Founder at ForthWrite ยท
    I built ForthWrite to fix generic AI email, and I still use it every day

    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.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž Cons:    10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)

  • How Onsurity Fills In Mental Wellness Coverage Gap In The Corporate Health Insurance Policies?
    We at Onsurity, believe that mental health is as important, and sometime even more, as physical health, which means it is not enough for the insurance benefits to get triggered at the time of hospitalization. Mental health should be prevented from becoming mental illnesses. This is the reason why we have partnered with Mindpeers to provide mental wellness counselling to our members.
