Top AI Writing Tools in 2025: Friday AI vs Jasper
Top AI Writing Tools in 2025: Why Friday AI Stands Out for Multilingual Emails
The AI writing landscape in 2025 is more competitive and diverse than ever. Whether you're a marketer, startup founder, customer service rep, or remote worker, chances are you've experimented with AI tools to speed up content creation. From long-form articles to bite-sized marketing emails, AI writing tools are now part of everyday workflows.
But which ones actually deliver on quality, ease of use, multilingual support, and—most importantly—email drafting? In this comprehensive guide, we’ll walk you through the top AI writing tools of 2025, compare their standout features, and explain why Friday AI has carved out a unique space in the fast-growing niche of multilingual email automation.
Why AI Writing Tools Matter in 2025
In a world of overflowing inboxes and distributed global teams, writing well—and quickly—has never been more critical. AI tools allow professionals to:
- Save up to 10 hours per week by drafting faster
- Maintain tone consistency across customer emails
- Translate and adapt messaging across markets
- Improve grammar and clarity without extra editing
The top players in the space include Jasper, Wordtune, QuillBot, Copy.ai, GrammarlyGO, and newer contenders like Friday AI and Lex. Each of these platforms has strengths, but they’re not all optimized for email use cases, especially across multiple languages.
What Makes a Top AI Writing Tool Today
Here are the most critical benchmarks we used to compare tools:
- Multilingual capabilities
- Prompt quality and tone control
- Templates for different use cases (email, social, blogs, resumes)
- Integration with work tools (Gmail, Chrome, Slack)
- Speed and accuracy
- Pricing transparency
- AI model diversity (GPT, Claude, proprietary)
Let’s see how each competitor stacks up.
Jasper AI: Premium Features, Premium Price
Strengths:
- Large template library
- Marketing and long-form focus
- Brand voice memory for teams
Drawbacks:
- $49+/month per seat makes it expensive for individuals
- Less intuitive for emails unless you build custom workflows
- Limited multilingual drafting
Jasper is best for marketing teams creating long-form sales pages or brand content. But for email-heavy workflows, it requires extra steps to make drafts usable.
Wordtune: Best for Editing and Paraphrasing
Strengths:
- Intuitive rewrite, expand, shorten tools
- Helpful for ESL users
- Clean UI with inline suggestions
Drawbacks:
- Weak on full-email generation
- Templates are generic and require customization
Great for polishing writing, but not ideal for zero-to-one drafting or mass email replies.
QuillBot: Academic Focus, Limited Email Support
Strengths:
- Citation tools for students and researchers
- Strong paraphrasing engine
Drawbacks:
- Lacks tone customization
- Not designed for business use cases
- No integrations with email or messaging apps
Ideal for essays or academic writing, but not an all-purpose AI assistant.
GrammarlyGO: Grammar-First, AI-Second
Strengths:
- Ubiquitous grammar correction
- Integrated with Gmail and docs
Drawbacks:
- AI suggestions often feel generic
- Weak on multilingual output
- Few pre-built email templates
GrammarlyGO is a natural extension of the popular grammar tool, but not a full-scale writing assistant yet.
Why Friday AI Is the Best for Multilingual Email Drafting in 2025
While many AI tools try to be all things to all users, Friday AI is built with a sharp focus: write better, smarter emails across languages.
Here’s how it stands out:
1. Official and Secure Gmail Integration
Friday AI connects directly to your Gmail account. It doesn’t just drop generic replies—it learns from your past threads and suggests responses that match your tone, style, and vocabulary. You can reply instantly from your inbox or launch the web app for longer drafts.
This is especially useful for:
- Salespeople who want to sound personal yet professional
- Customer support agents who need brand-accurate responses
- Managers replying to dozens of emails per day in their voice
2. Multi-Model Engine (Not Just GPT)
Most tools run on OpenAI’s GPT-3.5 or GPT-4. Friday AI uses multiple models, selecting the best one for each task.
This ensures:
- Short-form tone consistency
- Longer outputs without repetition
- Better handling of niche vocabulary in technical or legal emails
This multi-model architecture also improves speed—generating email replies takes seconds, not minutes.
3. Fluent Multilingual Support
Friday supports 20+ languages, including:
- Spanish
- French
- German
- Japanese
- Ukrainian
- Portuguese
More importantly, it doesn’t just translate—it adapts tone and style per language. Want to sound polite but firm in Japanese? Warm and casual in Brazilian Portuguese? Friday gets it right.
4. Integrated Keyboard and Web Assistant
Friday AI isn’t just a standalone app. Its keyboard extension (mobile) lets you use AI suggestions anywhere you write:
- Gmail
- Google Docs
- LinkedIn messages
- Notion
This universal interface makes it one of the most embedded assistants in your daily writing.
5. Templates for Every Email Use Case
Tired of blank pages? Friday comes loaded with over 36 ready-to-use templates:
- Cold outreach
- Job application
- Networking follow-up
- Apology letters
- Payment reminders
- Investor updates
You can also create your own prompt templates and save them to your workspace.
6. Corporate Plans and Team Tools
For businesses, Friday offers:
- Shared prompt libraries
- Central billing
- Usage analytics
- API integrations (coming soon)
It’s used by startups, agencies, and growing customer support teams that need a faster way to handle email volume without losing human tone.
7. Affordable, Transparent Pricing
While tools like Jasper charge $49/month or more, Friday keeps pricing simple:
- Free plan with limited credits
- Weekly: $6.99
- Lifetime license: $69.99 one-time
This makes it accessible for freelancers, students, and small teams.
