Jasper

Overview

Jasper (formerly Jarvis) launched in 2021 and grew to a $1.5 billion valuation faster than almost any other B2B SaaS tool, fuelled by demand from marketing teams that needed to scale content production without scaling headcount. It was built specifically for marketing use cases — not general text generation — and its feature set reflects that focus: brand voice training, campaign workflows, and integrations with SEO tools.

Following the release of ChatGPT and GPT-4, Jasper repositioned from an AI writer into a broader AI marketing platform. It now offers multi-step campaign workflows, a browser extension, image generation, and a document editor alongside its core long-form writing tools. The brand voice feature remains the most differentiated element — it is more effective at maintaining consistent tone across a large team than any competing tool.

Key Features

• Brand Voice — analyses your content to learn and replicate your brand's specific tone and style
• 50+ templates — structured workflows for blogs, ads, emails, social posts, and landing pages
• Jasper Chat — conversational AI interface for freeform content creation and research
• Campaign workflow — generate all assets for a marketing campaign in one flow
• Jasper Art — AI image generation built into the writing workflow
• SEO mode — integration with Surfer SEO for real-time optimisation guidance
• Chrome extension — use Jasper in any browser-based text field
• Team collaboration — shared brand voice, documents, and templates across team members
• Knowledge Base — store product information, FAQs, and brand guidelines the AI can reference

Pricing

Jasper has no free plan — a 7-day free trial is available. Creator ($39/month for one user) includes 1 brand voice and all templates. Pro ($59/month for one user) adds 3 brand voices, 10 knowledge documents, and collaboration features. Business plans are custom-priced and include unlimited brand voices, SSO, and dedicated support.

Best For

Jasper is the right choice for marketing teams that publish significant content volumes and need to maintain brand voice consistency across multiple writers and channels. Content agencies managing multiple brand identities, enterprise marketing teams with style guide requirements, and teams using Surfer SEO for content optimisation get the most from Jasper's differentiated features.

Limitations

Jasper lacks a free plan. The pricing — especially for teams needing multiple seats — is a barrier for smaller organisations. While brand voice training is the best available, outputs still require human editing for technical accuracy and genuine narrative insight. Some users report that outputs become formulaic after extended use without varied prompting.

Verdict

The leading AI writing platform for marketing teams where brand voice consistency is a real requirement. If you are publishing significant content volumes with brand standards to maintain, Jasper's differentiation justifies the price. For individual writers or simple content needs, cheaper alternatives deliver comparable output.
