Slack AI

Free: $0. Pro: $7.25/user/month when paid annually or $8.75 when paid monthly. Business+: $15/user/month annually or $18 monthly. Enterprise+ uses sales-based pricing. The pricing page labels Free and Pro as including Basic AI and Business+ as including Advanced AI; the exact feature set depends on plan and admin settings. The page was also displaying a 50%-off-for-three-months promotion for eligible Pro and Business+ purchases.

  • Slack's AI Principles page says AI features are included in paid plans, while the current pricing page labels the Free plan as having Basic AI. The exact production availability and limits of Free-plan AI could not be reconciled from the official pages.
  • Slack does not publish a single numeric usage allowance for all AI features; some capabilities state that plan limits apply.
  • No explicit, AI-output-specific ownership statement was located in the checked official Slack sources.

Official pages list capabilities including Slackbot, conversation and thread summaries, daily recaps, AI search, file summaries, workflow generation, huddle notes, translation, and enterprise search, with availability varying by plan. Slack states that Customer Data never leaves Slack-controlled infrastructure and is never used to train LLMs. Third-party LLMs are hosted within Slack's cloud environment; providers do not have access to Customer Data. AI only uses content the requesting member is authorized to access. Conversation summaries and search answers are ephemeral; recaps are stored for 90 days. Workflow-generated summaries stored in messages or canvases follow the organization's retention settings. Admins can disable or restrict native AI features.

Sonaopus

$99 USD one-time per profession-specific product, no subscription and no recurring charge. Five products: HR Management, Executive Assistant, Project Management, Real Estate, Recruiting. Free tier: up to eight generations per profession before purchase, with no signup or card. Lifetime access covers future updates to that profession's tool. Terms state that except where required by law all purchases are final and no refunds are offered, with the free trial given as the reason. A stale third-party mirror (devadex.com) still lists a retired pre-launch $59 price; the mirrored store account sonaopusaiworkflow.gumroad.com now returns 404 and the price on every live vendor page is $99.

  • No service address or city/country is published for the seller or data controller; the vendor declined to publish one beyond the Nigeria governing-law clause. The operator name is disclosed.
  • No data-export feature exists for locally stored workflow data; the Privacy Policy states this and directs users to contact support.
  • A stale third-party mirror (devadex.com) continues to advertise a retired $59 pre-launch price for the HR product. The mirrored Gumroad account now 404s; the mirror is outside the vendor's direct control.

Submitted via /submit-tool.html by the vendor on 2026-09-09 and held pending verification. The vendor published /privacy and /terms on 2026-09-12 and answered every outstanding question, so the listing was published 2026-09-13 with remaining caveats recorded in cons and unresolved_claims. Editorial entry written independently; no submission copy was reused. Verified on 2026-09-13: both legal pages live and substantive; all five Gumroad products at $99 with no subscription; shipped JavaScript writes only sonaopus_hr/_ea/_pm/_re/_role to localStorage, makes zero fetch/XHR/sendBeacon calls, and has no third-party script tags; handoff targets claude.ai/new, chatgpt.com/ and gemini.google.com/ carry no query parameters. Operator: Praise Boyinde, sole proprietor, no registered entity, governing law Nigeria. The domain publishes no MX records, so the Gmail address printed in both legal pages is the only reachable contact. Re-checked 2026-09-13 against the live homepage and a vendor email the same day. Closed: the homepage FAQ no longer says “Nothing stored”; on-page copy now matches the Privacy Policy (everything runs in the browser, progress saves locally, nothing is sent until you hand it to an assistant). Closed: a standalone legal-review FAQ (“Nothing happens without you”) is live and treats ER letters, HR policies, and similar outputs as drafts to verify, with legal or compliance risk flagged on-screen. Closed: affiliate terms were stated in writing by the vendor on 2026-09-13 — 40% flat one-time commission ($39.60 per $99 product), no recurring commission because there is no subscription, 30-day cookie, attribution and payout through Gumroad; signup at https://sonaopus.com/ or https://sonaopus.gumroad.com/affiliates.
