For agencies producing content for several clients, Byword and Scalenut both keep brands in separate workspaces. Scalenut adds team collaboration and an approval workflow, while Byword adds a public API and an MCP server, so the choice is between review workflow and programmatic control. DeepSmith is a strong alternative on per-client isolation: Multi-Workspace gives each client its own Deep IQ context, content and plan, billed and limited independently, with a read-only API and MCP server to report on each client's data.
Byword vs Scalenut for agencies comes down to what sits around the client workspaces. Both tools hold more than one brand in a single account, so the real questions are who on your team can review a draft and whether you can pull the work into your own systems. This page looks at that one job. The broader comparison, covering batch publishing and AI answer tracking, is in the full Byword vs Scalenut comparison. DeepSmith joins as a third option built around keeping each client fully separate.
Byword vs Scalenut for agencies: the short answer
- Choose DeepSmith if each client needs its own isolated workspace with separate brand context, content, plan and billing, plus read-only API and MCP access for reporting.
- Choose Byword if your team wants programmatic control: 5 client domains on the $99 Starter plan, a REST API from the $299 Standard plan, and an MCP server.
- Choose Scalenut if several people review work inside the tool: unlimited workspaces and unlimited team members on the $199 Professional plan, with an approval workflow and no API.

Byword
Byword is a self-serve AI article writer. It researches keywords, drafts articles one at a time, in batches or from programmatic templates, and publishes them to a connected CMS. For agencies, its work is organized by domain, with settings and connections kept per domain, and its about page names agencies with client sites as a target customer.
The standout for this job is access. Byword has a REST API and a remote MCP server of about 40 tools, with optional review gates before spend or publishing actions. The limit is that these sit on higher tiers. Free and Starter are solo only with no API, and seats start on Standard at $299 a month with 3 seats.
Reviews are few and mixed. Byword shows 3.5/5 on G2 from 3 reviews and 2.8/5 on Trustpilot from 7 reviews, checked in September 2026, so the sample is small and mostly old.
Scalenut
Scalenut is an AI SEO writing and optimization suite that bundles keyword clustering, drafting, content scoring and AI answer tracking in one subscription. For agencies, a workspace holds one domain, and the count rises by plan: 1 on Starter, 2 on Plus and unlimited on Professional. Multiple Brand Kits store a tone and keyword set for each client, and Scalenut's pricing FAQ says Professional is designed for agencies.
The standout is team collaboration. Plus allows 4 team members and Professional allows unlimited members, with team collaboration and an approval workflow in its On Page Pro tool. The limit is access from outside the app. Scalenut's help center says it does not currently offer an API, and no MCP server is listed.
Scalenut shows 4.7/5 on G2 from 315 reviews and 4.8/5 on Capterra from 397 reviews, checked in September 2026. Trustpilot is lower at 3.2/5 from 159 reviews.
DeepSmith: the alternative that keeps each client isolated
Byword and Scalenut both let one account hold several clients, and both give each client its own voice settings. In Byword the unit is a domain, and in Scalenut it is a workspace tied to one domain. DeepSmith treats the client as the unit of everything. Multi-Workspace runs each client fully isolated, with its own Deep IQ context (brand, products, personas, voice, visual guidelines and content types), its own content and its own plan. Each workspace is billed and limited independently, and you invite owners and members per workspace.
That isolation carries into reporting. The read-only REST API and the MCP server work per workspace, with scoped API keys, 120 requests per minute and no credits spent on reads. The MCP server has 23 tools and works with Claude, Claude Code, Cursor, VS Code and others. Both read workspace data and do not publish, so finished articles go out through Produced Content and your CMS connection.
Tracking and writing run on the same platform. AI Visibility reports how each client's brand shows up across AI engines, and the Writer produces the publish-ready article from that client's Deep IQ context. Pricing is $99 a month for Pro, $199 for Grow and $399 for Scale, or $80, $160 and $299 billed annually, with a custom Enterprise plan, a 7-day free trial and no long-term contracts. Pro includes 5 seats. DeepSmith is rated 4.8/5 on G2 and is SOC 2, GDPR and ISO certified.
Client separation and workspaces
On this axis the two tools are level on capability and differ on cost per client. Byword gives more clients at the entry price, and Scalenut gives unlimited clients at a lower top price.
Byword's Starter plan at $99 a month covers 5 domains, and Standard at $299 makes domains unlimited. Scalenut's Starter at $59 covers one workspace, Plus at $89 covers two, and Professional at $199 makes workspaces unlimited. An agency with four or five clients and one writer starts cheaper on Byword Starter, since Scalenut would need Professional. An agency with ten clients pays $299 on Byword and $199 on Scalenut.
What DeepSmith does: each client gets a workspace of its own, with its own Deep IQ context, content and plan, so one client's voice, personas and drafts never mix with another's. Setting up a new client means starting a workspace from that client's website, and the brand brief, competitors, starter tracking prompts and first batch of ideas are populated before you pay.
Team review and approvals
Scalenut leads on review. Byword has roles, and Scalenut has collaboration and an approval step.
Byword's seats come with Owner, Editor and Viewer roles per domain on Standard and Scale, and its MCP review can hold spend and ship actions for approval. No commenting or editorial approval workflow is described in the app. Scalenut offers team members on Plus and Professional, team collaboration on Professional, and an approval workflow in On Page Pro, which proposes site fixes and deploys them once approved. Comments are not described. Because that approval step sits in On Page Pro, it's worth checking that it fits how your editors sign off an article before you rely on it.
What DeepSmith does: you invite owners and members to each client's workspace, so the people reviewing one client's work are the members of that client's workspace. Finished articles land in Produced Content, where you review, edit and preview the live article before publishing.
API and system connections
Byword leads on programmatic control, and it is the only one of the two with an API or an MCP server on record.
Byword's REST API covers articles, campaigns and account data, with bearer keys, asynchronous generation and 1 credit per article, on Standard and Scale. Its MCP server uses OAuth or an API key. Publishing targets include WordPress, Webflow, Ghost, HubSpot and Medium, with exports to Notion, Google Docs, Sheets and Airtable, plus Slack, webhooks and Zapier. Scalenut publishes to WordPress and Shopify from Plus and up, and its Link Manager and On Page Pro deploy changes to the CMS, but the help center says there is no API.
What DeepSmith does: the API and MCP server let you pull each client's AI visibility, Content Map, content library and Deep IQ data into your own reports, with one key per workspace. Signed webhooks tell your own systems when content status changes, and articles publish straight to WordPress, Webflow, Strapi, Sanity or Contentful.
Pricing as the client list grows
Neither tool prices per client, so the cost depends on how fast the client list grows past the entry tier.
Byword runs $99, $299 and $999 a month for Starter, Standard and Scale, which include 25, 80 and 300 articles. For agencies beyond that, its Unlimited plan is a $1,999 monthly platform fee plus your own model keys, with unlimited seats. Scalenut runs $59, $89 and $199 a month for Starter, Plus and Professional, and Professional includes 75 GEO articles a month on monthly billing. Scalenut also advertises annual offers of $24, $36 and $80 a month, though its pricing pages show some mismatches, so confirm the numbers before you quote a client budget. Scalenut is cheaper for an agency that mostly needs workspaces and seats, and Byword gives more article volume at the top.
What DeepSmith does: because each workspace is billed and limited independently, one client's usage doesn't draw down another's. Plans run from $99 to $399 a month, with Enterprise on custom limits and a dedicated account manager.
Which should you choose
Byword or Scalenut for agencies depends on whether your team reviews work in the tool or controls it from outside.
- DeepSmith: agencies that want every client in a separate workspace with its own brand context, plan and billing, and that want to track AI visibility and produce the content from one platform.
- Byword: agencies that run content through scripts, automation tools or an AI assistant, and that have several clients on domains ready to go on the Starter plan.
- Scalenut: agencies where several editors and account managers work inside one tool, and where unlimited workspaces on a low monthly plan matter more than API access.
