TechGuru compared current vendor-published product, pricing and business-plan information. This edition is research-based and does not claim hands-on testing. Product packaging changes frequently, so verify the linked official sources before purchasing.
“AI writing tool” now covers very different products. Some are general assistants that can research, analyse and draft; others are specialist marketing platforms built around brand voice, campaign workflows and governance. A business should choose by workflow and review requirements rather than by the number of templates advertised.
Quick shortlist by requirement
| Need | Product to investigate | Reason to shortlist |
|---|---|---|
| General business writing plus research and analysis | ChatGPT | Broad assistant rather than a writing-only product; Business adds a managed workspace and business-data protections. |
| Writing inside Gmail and Docs | Gemini with Google Workspace | AI is integrated into the productivity environment many businesses already use. |
| Marketing teams needing brand controls and repeatable campaign workflows | Jasper | Jasper positions its paid product around marketing workflows, Brand Voices, Knowledge and Audiences. |
| Editing and consistency across existing business writing | Grammarly | Worth evaluating when the primary problem is improving and standardising existing writing rather than generating entire workflows. |
ChatGPT: broader than an AI copywriter
ChatGPT is relevant when writing is only one part of the workflow. A business can use the same assistant to organise source material, analyse files, draft alternatives and revise copy against a checklist. For teams, compare the business workspace rather than assuming a personal subscription provides the same administration and data controls.
OpenAI currently publishes ChatGPT Business Standard at $20 per user/month when billed annually or $25 monthly, with a two-seat minimum. OpenAI states that Business content is not used to train its models by default. Pricing and usage policies can change.
Good fit
- Teams that need drafting plus analysis, research and file-based work.
- Businesses that want one general assistant across several workflows.
- Teams prepared to create their own review process and brand instructions.
Gemini with Google Workspace: investigate it if your work already lives in Workspace
The strongest reason to evaluate Gemini is integration rather than a generic claim that one model “writes better”. Google includes Gemini capabilities across Workspace plans and describes AI assistance in Gmail, Docs, Meet and other Workspace apps. That can reduce copy-and-paste between a separate AI service and the documents where work is actually completed.
For a small business already paying for Workspace, compare the incremental workflow value and the plan you actually need rather than buying a separate writing product automatically.
Jasper: specialist marketing workflow
Jasper is positioned specifically around marketing. Its current Pro plan includes one seat, Canvas, marketing agents and controls for Brand Voices, Knowledge assets and Audiences. Jasper currently lists Pro at $59/month when billed annually or $69 monthly; Business uses custom pricing and adds broader governance and customisation.
That makes Jasper more relevant when maintaining brand consistency across repeated campaigns is a central requirement. It is harder to justify when a solo business simply needs occasional drafting.
Grammarly: evaluate it as an editing layer
Grammarly is best evaluated differently from general AI assistants. Ask whether the business needs consistent rewriting, tone and editing in the places employees already write. If the real requirement is deep research, data analysis or multi-step AI workflows, compare a broader assistant as well.
Our five-step buying test
- Select three real documents: for example a customer email, landing page section and internal update.
- Give each shortlisted tool the same approved facts and brand guidance.
- Record drafting time plus editing and fact-checking time.
- Count unsupported claims, tone corrections and information that had to be restored after rewriting.
- Compare the realistic team plan and annual cost, not a temporary trial or promotional price.
What businesses should check before uploading content
Review the vendor’s current privacy, retention, training and administration controls for the exact plan being purchased. Do not assume that consumer and business plans handle organisational data identically. Define which customer, employee, financial or confidential information staff may enter before rolling the tool out.
