Jasper

What it is

Jasper is an AI writing platform aimed at marketing teams rather than at individuals. The distinguishing piece is Brand Voice: you define how your company sounds, and output is generated against that definition instead of against a generic default. Pro includes 2 Brand Voices, Business allows unlimited.

Around the writing sit Canvas for building content, agents for core marketing workflows, image generation and editing, and support for more than 30 languages. It connects to Webflow, Google Docs, Slack, BigQuery, Google Sheets, Zapier and Make, and its browser extension works inside Gmail, WordPress, HubSpot and LinkedIn, which is where marketing writing actually happens.

Who it's for (and who it isn't)

It fits a marketing team producing a lot of content across channels, where consistency of voice is a real problem because several people write. That is the situation Brand Voice was built for, and it is what justifies the price over a general chat assistant.

It is a poor fit for a solo founder writing occasional posts. At $69 per month per seat, or $59 billed annually, with no free plan and a 7-day trial, Jasper asks for a commitment that only makes sense at volume. If you write for yourself and want help with the blank page, a general assistant costs a fraction of it.

Pricing

Jasper is paid. Pro is $69 per month per seat billed monthly, or $59 per month per seat billed annually, and includes 2 Brand Voices, Canvas, agents for core marketing workflows, image generation, chat and document collaboration. Business is custom priced and adds unlimited Brand Voices, API access, a custom AI agent builder, Jasper Grid for systematic content execution, SSO and enterprise governance. There is no free plan, only a 7-day free trial.

Per-seat pricing at this level means the team size decision comes before the tool decision. Three seats on Pro is over $2,000 a year, so be specific about who needs to generate and who only needs to review.

Set it up

Official guide: Brand Voice

1. Start the 7-day free trial on Jasper's website. Jasper has no free plan, so the trial is the way in. After that, Pro costs $69/month/seat billed monthly or $59/month/seat billed annually (a seat is one person who uses the account). Have two or three pieces of your own writing ready, such as an old blog post or a newsletter. Your trial account is now ready.
2. On your home page, look at the left side and find "Jasper IQ". Click "Brand Voice" there, then click "+ Add Brand Voice". A Brand Voice is a saved description of how you write, which Jasper reuses every time. Choose whether the voice is visible to your workspace or private to you. You now see where to add your examples.
3. Upload up to 8 examples: pasted text, files (.txt, .pdf or .docx) or website addresses. At the bottom, enable the excerpts that sound most like you, because this makes the voice more accurate. The top of the page now shows a short description of your writing.
4. Click "Preview Brand Voice" at the top of the page. Choose "Blog Post", "LinkedIn Post" or "Product Description", type a topic and click "Generate". You now see two versions, one with your Brand Voice and one without.
5. Click "Save changes" in the upper right corner. If the version with your voice did not sound like you, change your examples first. Your Brand Voice is now saved.
6. Write something you need this week, such as a LinkedIn post, in Agents (Jasper's ready-made AI helpers), the document editor or Chat. Select your voice when you start, then edit the result until you would publish it under your name. You now have a first draft in your voice, ready for your edits.

When this works, you have one saved Brand Voice and one real piece of writing made with it, so you can judge whether it needs less editing than writing alone.

On Business (on request): unlimited Brand Voices (the Pro plan includes 2), API access (a way for other software to talk to Jasper) and a custom agent builder (a tool for creating your own Jasper agents).

Strengths and limitations

The strength is consistency across a team. Brand Voice plus workflow agents means five people can produce content that sounds like one company, which is a genuine operational problem that generic assistants do not solve.

The limitations are cost and the editing floor. There is no free plan and no cheap tier, so the tool is out of reach for the users who would experiment with it. Generated marketing copy still needs a human edit before publication, and treating the output as finished is the fastest way to produce content that reads as machine-made. And per-seat pricing means the bill grows with your team rather than with your output. See Jasper vs Copy.ai for the direct comparison.
