## ForthWrite

ForthWrite is an AI writing assistant aimed at people who live in their inbox. Instead of asking you to learn a new tool, it installs as a Gmail and Outlook web extension and adds a drafting widget directly to the compose box. On first use it analyses emails you have already sent to build a voice profile, so the very first suggested reply starts close to something you would actually send. The model is tuned for nuance and can also take a manual persona prompt when you want a specific register.

The product family spans three levels. Inbox is the individual product, with a free tier that provides 10 AI drafts a week plus voice matching, and a Pro tier that unlocks auto-drafting, batch drafting of long threads, a Prompt Lab for versioning and A/B testing prompts, recipient- and intent-aware drafting, voice dictation, smart retrieval over your past mail, and performance analytics. Teams extends Pro drafting to every seat in an organisation with a shared voice baseline, a shared prompt library, a team analytics dashboard, and a review record showing what was drafted, what changed, and which model produced it.

ForthWrite also sells consulting to professional-services firms such as accounting, tax, advisory, lending, and brokerage practices. Those engagements begin with a free 30-minute diagnostic and can extend into a paid audit, a 30-60 day roadmap, and implementation with written SOPs. The company is clear about its operating principle: ForthWrite drafts, and a person sends, so accountability and signature stay with the user.

**Pricing & Plans:** Freemium with a free forever tier (10 drafts per week, voice matching, no card required), Pro at $24/month billed annually ($29 monthly), and Teams from $59/seat/month billed annually ($79 monthly, 2-seat minimum). All paid plans start with a 14-day free trial; Teams gets a 30-day trial. An optional Bring Your Own API Key mode takes roughly 17% off. Consulting is scoped separately per firm.

- **Voice matching from your sent mail:** ForthWrite reads emails you have already sent to build a voice profile, then refreshes it roughly every 50 captured emails so drafts keep tracking how your writing evolves.
- **Auto-draft and batch drafting:** Pro users can have replies waiting when they open Gmail, and clear dozens of threads in parallel instead of writing each one by hand.
- **Recipient- and intent-aware drafting:** Drafts adapt tone to the person you are replying to and treat follow-ups, intros, and status updates as genuinely different jobs rather than one generic template.
- **Prompt Lab and performance analytics:** Version control and A/B test your prompts, then track acceptance rate, voice match, and intent mix on a measurable improvement curve.
- **Team standards and compliance guardrails:** On Teams, a shared voice baseline and shared prompt library keep every seat consistent, and a draft that breaks a firm rule stops the preparer with a written reason.

**Strengths:** Drafts pick up your real tone because the voice profile is built from mail you have already sent; Works inside Gmail and Outlook web with no migration or new inbox to learn; Strong free tier with 10 drafts a week and voice matching included, no card required; Teams adds shared prompts, team analytics, and a review record that firms usually need

**Limitations:** Web-based Gmail and Outlook only; there is no full desktop client experience; Full value depends on having a decent history of previously sent emails for the voice profile; Consulting engagements are custom-scoped, so pricing is not published

## Serif

Serif builds AI agents that take over the repetitive but fiddly parts of running a business: collecting documents, answering routine questions, chasing paperwork, and keeping follow-ups on track. You point the platform at real work, it learns how your team handles it, and then it runs the task continuously. When an agent encounters something outside its instructions — an unusual request, a missing document, an ambiguous clause — it routes the job to the right person rather than guessing. The result is automation that reaches completion instead of stalling halfway through a multi-step process.

The platform organizes this around three stages: diagnose, train, and run. Diagnosis surfaces workflows worth automating, training teaches agents how your business operates, and running puts the work on autopilot. Typical deployments cover document collection and processing (requesting, reading, and verifying files until a job is complete), compliance intake and quoting, complex support, accounting and tax tasks, real estate closing files, law firm engagement letters and questionnaires, and insurance claims packet collection. Agents work 24/7 across email threads, shared inboxes, and document attachments.

Security is treated as a first-class requirement. Serif states that your email is never used to train models and never stored on its servers, that everything the platform learns is encrypted at rest, and that its practices are audited by a third party. It publishes SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR compliance claims. The product also offers a standalone personal email assistant and a free inbox report as an entry point, with paid plans for teams that need shared inboxes and full automation.

**Pricing & Plans:** Paid subscription with a free starting point. Serif offers a free inbox report and a downloadable personal email assistant, while shared inbox and full agent automation capabilities are sold on paid plans. Specific tiers and per-seat pricing are shown on request or at signup.

- **Email & Document Workflows:** Agents read email threads, pull attachments, run lookups, apply your policies, and write replies automatically, covering tasks from routine answers to multi-step document chasing.
- **Document Collection & Processing:** Serif requests paperwork, reads what comes back, checks it against what you actually need, and keeps following up until the file is complete — ideal for closings, claims, and intake packets.
- **Human-in-the-Loop Escalation:** When an agent is unsure how to proceed, it routes the job to the right person for review, so automation handles volume while judgment stays with your team.
- **Shared Inbox & Team Tools:** Manage addresses like info@, support@, billing@, and closing@ from a shared inbox, with email management, autoresponders, and customer service agents built in.
- **Enterprise-Grade Security:** Email is never used to train models or stored on Serif's servers, learning is encrypted at rest, and the platform meets SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR standards.

**Strengths:** Handles full multi-step email and document workflows, not just drafting replies; Transparent security posture: no model training on your email and no email stored on its servers; Escalation keeps human judgment in the loop for ambiguous cases; Covers a wide set of industries including legal, insurance, real estate, and accounting

**Limitations:** Specific pricing tiers are not published on the homepage and require contacting sales or signing up; Best value requires committing to the platform's workflow model and training agents on your processes; Automation depth depends on how well you define and document your own rules
