ProBackup provides daily, automated backups for the productivity and CRM apps your team runs on: Asana, ClickUp, Monday, Airtable, Trello, Notion, Jira, Slack, HubSpot, Podio, and more. Connect each app via secure OAuth and we automatically back up your data every 24 hours. No scheduling, no maintenance.

Your SaaS vendor backs up their own servers for their disaster recovery, not to protect your work. If someone on your team (or an AI agent) deletes or overwrites a record, that gap is yours to cover. ProBackup fills it.

Browse everything in the Vault, view the full revision history of any record, and search across all your data and all platforms. When something goes wrong, restore exactly what you need - a single field, a comment, or an entire project - with point-in-time recovery. Optional Google Drive sync gives you an extra layer of redundancy, independent of ProBackup. SOC 2 compliant.

Three plans (Plus, Pro, Premium) that scale with your data. Trusted by 2,500+ teams for business continuity and peace of mind.

Works inside Gmail and Outlook on the web.

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.

Questions & Answers

As answered by people managing ProBackup and ForthWrite.

Which are the primary technologies used for building your product?

ProBackup's answer

Infrastructure runs on AWS. Backup files are stored in AWS S3 and metadata (IDs, tree structure, webhook registrations) in AWS RDS, encrypted at rest with AES-256 via AWS Key Management Service. Customers can choose from nine AWS regions (Ireland, Frankfurt, London, North Virginia, Montreal, Sรฃo Paulo, Sydney, Singapore, Tel Aviv). ProBackup connects to each source app through its official API over OAuth, with all tokens AES-256 encrypted using unique initialization vectors. Data in transit is secured via SSL/TLS on port 443, enforced with HSTS. The backup engine is incremental and versioned, creating independent snapshots each cycle.

ForthWrite's answer:

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

What's the story behind your product?

ProBackup's answer

ProBackup started in 2017 as Momentum Tools, originally built to back up Podio. As more teams moved their operations into a growing range of SaaS apps and hit the same blind spot โ€” that vendors don't protect customer data from customer-side mistakes โ€” the product expanded. In August 2020 it relaunched under the ProBackup brand, adding Asana as the first new platform, and grew steadily from there to cover 20+ apps. A major platform refresh came in September 2023, SOC 2 compliance was achieved in May 2025, and the current version (3.0), with a completely redesigned UI, launched in August 2025. Today ProBackup is a lean, product-led company (ProBackup BV) serving ~2,500 customers.

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.

What makes your product unique?

ProBackup's answer

ProBackup is purpose-built for SaaS productivity and CRM apps โ€” not files or servers. It backs up the data living inside Asana, ClickUp, Monday, Airtable, HubSpot, Trello, Notion, Jira, Slack, Podio, and 20+ other tools, fully automatically every 24 hours. The key insight: your SaaS vendor backs up their own infrastructure for their disaster recovery, not to protect your work. If your team โ€” or an AI agent acting inside the app โ€” deletes or overwrites a record, the vendor can't bring it back. That gap is what ProBackup fills. Backups are incremental and versioned, so you get point-in-time recovery and can restore exactly what you need: a single field, a comment, a whole project. Optional Google Drive sync adds a second, independent layer of redundancy you control.

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?

ProBackup's answer

A few reasons. Breadth: one account covers 20+ platforms, and you can add unlimited apps on any plan. Granularity: restore a single record or an entire board, with point-in-time recovery to any previous day. No setup overhead: backups run automatically every 24 hours โ€” no scheduling, no maintenance. Independent redundancy: unlike tools that dump a new CSV after every cycle, ProBackup syncs to a live Google Sheet you own, so you keep a usable copy even if ProBackup is unavailable. And trust: SOC 2 compliant, AES-256 encryption, isolated key management (no one at ProBackup can read your raw data), and a choice of nine AWS storage regions worldwide. It's a focused, product-led tool โ€” self-serve onboarding, simple UI, transparent pricing.

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?

ProBackup's answer

Teams that run their daily operations inside SaaS productivity and CRM apps and can't afford to lose that data โ€” typically SMBs and mid-market companies, often without a dedicated IT/backup function. The buyer is usually the admin, operations lead, or team owner responsible for an Asana, ClickUp, Monday, HubSpot, or Airtable workspace who recognizes that accidental deletion, a rogue integration, a departing employee, or an AI agent gone wrong could wipe out work the vendor won't restore. ~2,500 customers today, with a 35% trial-to-paid conversion rate.

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.

    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)
