Most small businesses do not need an AI writing tool that does everything. They need one that fits the writing they already do: product pages, emails, social posts, proposals, help articles. The wrong choice usually costs money in two ways, a subscription that is bigger than the workload and hours spent editing output that does not match your voice.
This guide compares seven widely used options, from general-purpose assistants to marketing-focused platforms. We focus on what the vendors publish about pricing, free plans and features, and on who each tool appears to suit.
Disclosure. Claude, one of the tools covered here, is made by Anthropic and was used to help draft this guide. Every price and feature below was checked against the vendor pages linked in each section.

How we selected these tools
We included tools that small businesses commonly consider, that publish pricing publicly, and that cover different jobs. We left out tools whose pricing or features we could not confirm on an official page. The criteria were:
- Fit for small teams: clear plans for one to five users, without enterprise-only gates.
- Transparent pricing: published prices and plan limits.
- Writing-specific features: brand voice, templates, editing, SEO support or collaboration.
- Free access: a free plan or trial so you can test with your own content.
The 7 tools
1. ChatGPT: flexible general assistant
ChatGPT offers a Free plan, Go at $8 a month in the US (per OpenAI), Plus at $20 a month, and Pro tiers at $100, $200 and $500 a month, according to OpenAI’s help center. Projects, voice, web search and file uploads are available, with higher limits on paid plans. Go may include ads and omits some legacy models.
- Strengths: broad range of tasks, low-cost Go tier, large ecosystem.
- Limitations: no built-in brand-voice library; you shape tone with your own instructions.
2. Claude: long-form drafting and editing
Claude has a Free plan, Pro at $20 a month ($17 a month billed annually) and Max plans from $100 a month. Team plans start at $20 per seat on annual billing. Usage limits reset on a rolling five-hour window, so heavy users may hit caps on lower plans.
- Strengths: projects for reusable context, document handling, a usable free tier.
- Limitations: usage caps, and no dedicated marketing templates.

3. Jasper: marketing workflows and brand voice
Jasper Pro costs $69 per seat monthly or $59 billed yearly, with a 7-day trial and no free plan. Pro includes Brand Voices (two), Audiences (three) and Canvas. Business is custom-priced with unlimited voices and audiences, API access and SSO.
- Strengths: brand-voice features, marketing agents, team-oriented workflow.
- Limitations: highest entry price here; Pro caps voices and audiences; cards only.
4. Copy.ai: chat for small teams
Copy.ai positions its Chat plan, $29 monthly or $24 billed annually, for small teams. It includes five seats and models from OpenAI, Anthropic and Gemini. Higher plans start at $1,000 a month and center on workflow automation, which most small businesses will not need.
- Strengths: multi-model access and five seats at a low price.
- Limitations: a large price jump to the workflow tiers; free plan terms are not published on the page we checked.
5. Writesonic: content with an SEO and AI-search focus
Writesonic‘s pricing page now describes an AI search visibility and SEO platform. Starter is $79 a month billed annually for one user and 15 AI articles; Basic is $199 and Growth is $399. Extra users are $50 each on eligible plans.
- Strengths: SEO orientation, Google Search Console and WordPress integrations on all plans.
- Limitations: monthly-billing prices are not shown; priced above general assistants.
6. Grammarly: polish across every app
Grammarly has a Free plan with 100 AI prompts a month. Pro costs $12 per member a month billed annually ($144 a year) or $30 a month billed monthly, according to Grammarly’s support page. It adds 2,000 prompts per member per month, full-sentence rewrites, tone adjustment and plagiarism and AI-text detection, and offers a 7-day trial.
- Strengths: works where you already write; strong for editing rather than first drafts.
- Limitations: less suited to long-form generation.
7. Notion AI: writing inside your workspace
Notion AI lets teams draft and improve text inside pages and ask questions with citations. Free and Plus plans include only a limited trial; Business adds Notion Agent and AI Meeting Notes. Custom Agents use credits sold at $10 per 1,000 credits.
- Strengths: fits teams whose notes and docs already live in Notion.
- Limitations: full AI access sits on the Business plan.
Pricing and limitations to watch
- Per-seat versus flat: Jasper and Notion charge per seat; Copy.ai Chat bundles five seats.
- Usage caps: ChatGPT, Claude and Grammarly meter usage in different ways, so a free plan that suits an occasional user may not suit daily drafting.
- Output review: every tool can produce errors. Fact-check claims, numbers and quotations before publishing.
Best choice by use case
- Solo owner on a budget: start with a free plan from ChatGPT or Claude, then add Grammarly for editing.
- Marketing team with a defined voice: Jasper is built around brand voices and audiences.
- Content marketer focused on search: Writesonic if you want SEO and AI-visibility tools in one place.
- Team documenting work in Notion: Notion AI avoids switching tools.
- Small team that wants shared access: Copy.ai Chat includes five seats.
How to choose
- List your three most frequent writing tasks.
- Run the same task on two free plans or trials using your real material.
- Count how long editing takes, not just how fast the draft appears.
- Check seats, usage limits and billing basis before you commit.
FAQs
Do I need a paid AI writing tool?
Not always. Free plans from general assistants handle many small-business tasks. Upgrade when limits or missing features slow real work.
Will AI content rank in search?
Search engines evaluate usefulness and quality, not whether a tool was used. Add original expertise, verify facts and edit for clarity.
Can these tools learn my brand voice?
Jasper offers dedicated Brand Voices, and projects or instructions in assistants like ChatGPT and Claude let you save guidance. Results vary, so review output.
Conclusion
For most small businesses, a general assistant plus an editing tool covers the majority of writing. Move to Jasper or Writesonic when brand voice or SEO workflow justifies a higher price. Test two options with real tasks before paying, and revisit pricing pages, since plans change often.
