Writing assistant across 12 named apps, with AI prompt caps of 100 free, 2,000 on Pro and unlimited on Enterprise, plus per-plan model-training defaults.
Teams that need writing suggestions to follow a house style wherever people already work, rather than inside one more editor. The business page names Style Guide (upload a company style guide so suggestions stay aligned), Brand Tones (a tone profile built from company voice), Knowledge Share and Analytics, and the product runs in Google Docs, Microsoft Word, Gmail, Outlook, Slack, Salesforce, PowerPoint, LinkedIn, Teams, Google Sheets, Zendesk and Jira. Enterprise adds SAML single sign-on and SCIM provisioning.
Anyone buying a long-form generator. AI capacity is metered in prompts, not words - 100 a month free, 2,000 per member on Pro, unlimited only on Enterprise - and the plans page lists Pro at "$12 USD" with no billing period stated, so you cannot tell what you are agreeing to. Model-training defaults cut the wrong way for self-serve buyers: Free, Premium and single-user Pro accounts have Product Improvement and Training on by default, and multi-user Pro accounts bought on the website also start on, with only an admin able to opt the organisation out. Even with the control off, aggregated or de-identified writing statistics are still collected. No price or seat minimum is published for Business or Enterprise, and Style Guide and Brand Tones are named on the business page without any documented rule mechanics. Branding is also in flux - the trust page footer credits "Superhuman Platform" and Enterprise is delivered through "Superhuman Go".
Pros
Cons
In prompts, not words. The plans page publishes one hundred AI prompts a month on the free tier, two thousand prompts per member per month on Pro, and unlimited prompts per member on Enterprise. No word allowance is published on any tier, so if your use case is long-form drafting volume, the prompt count is the number to model against rather than any word figure.
It depends on how you bought it. The support article states Product Improvement and Training is off by default on Enterprise-tier accounts, on Pro and Business accounts purchased through Sales, and on all Education accounts, with no toggle on converted accounts. Free, Premium, single-user Pro and multi-user Pro bought on the website all default to on, and an admin must opt the organisation out.
Only lightly. The business page names Style Guide, describing it as uploading a company style guide so suggestions stay aligned with brand decisions, and names Brand Tones as a tone profile built from company voice. Neither has published rule mechanics, rule types or enforcement behaviour on the pages reviewed, so treat the depth of enforcement as something to verify in a trial rather than assume.
Yes, but not for text generation. The developer site documents an HTTP REST interface with reference sections for Analytics, License Management and Writing Score, plus AI Detection and Plagiarism Detection, both marked beta. These are administrative and scoring endpoints suited to reporting, provisioning and quality checks. There is no documented endpoint for generating or rewriting copy, and no SDK is mentioned.
