The Short Answer
Client approval software comes in two kinds. Social tools such as Planable and Kontentino plan, approve, and publish posts. Proofing tools such as Filestage and Ziflow review video, design, and documents. GoMimic creates written content in each client’s voice, then gets it approved by link with no account.
Approval tools get a client’s yes, and writing tools write in a brand’s voice. GoMimic does both, for agencies with many clients: it creates each client’s content in that client’s voice, gets it approved by link with no account, and hands it to your team.
Teams that need a client’s sign-off on social posts or creative files.
ForTwo kinds
Social tools like Planable and Kontentino plan, approve, and publish social posts. Proofing tools like Filestage and Ziflow review video, design, documents, and websites, and don’t publish.
CoversApproval, plus their own specialty
Planable and Kontentino add a calendar, publishing, and writing help, and Kontentino lists a brand voice feature. Filestage and Ziflow add review stages, version comparison, audit trails, and automated checks.
PricedPer workspace, user, or seat
Planable prices per workspace, Kontentino by users and social profiles, and Filestage and Ziflow by seats. Ziflow’s reviewers are unlimited.
Agencies with a roster of clients.
ForAgencies running five to thirty clients on retainer
Agencies of one to ten people, where the recurring cost isn't governance. It's creating content in a different voice for each client, getting it approved, and delivering it.
VoiceSet by you, and it keeps learning
A client voice your team sets and GoMimic keeps learning: your description, rules, brand guidelines, and Business Facts, plus the client’s writing, calls, and the approvals you keep. Approvals and client reporting included rather than tiered.
PricedOne flat price per agency
One flat price per agency, not per client. Pro includes up to 3 people, Agency up to 10.
What GoMimic Does
GoMimic counts a writing habit only once it keeps turning up in a client’s writing, so one unusual post can’t bend that client’s voice.
In GoMimic, a client approves by link with no login, nothing approves itself, and a link nobody answers expires, so silence never becomes a yes.
GoMimic locks approved text and keeps each decision on a record that is added to and never rewritten, so an agency can show who approved what, and when.
Where They Diverge
WritingBrought to it, or created
Approval tools: Social tools help your team write the post; proofing tools review what you upload.
GoMimic: GoMimic writes from the material you give it and the client’s Business Facts. In GoMimic, your team sets each client’s voice: how they sound, your rules and examples, their brand guidelines and Business Facts, or a GPT or Claude Project you bring in. It keeps learning from the client too: their writing and calls, and the comments and approved posts you choose to keep. A habit counts once it keeps turning up, and phrases you quote in Things Never to Say, plus your Stock Phrases, are checked on every new piece.
Client approvalEach has a way in
Approval tools: Filestage needs no account. Planable lets occasional approvers view and comment without one, Kontentino’s clients join by invitation, and Ziflow has public proof links.
GoMimic: Client approval by link with no account, in rounds, with a record that is added to and never rewritten. Approved text can’t change unless your team reopens it, and the approved copy stays on record. The client needs no account.
Nobody answersNever a yes
GoMimic: Nothing is approved. When the link closes, the post is still waiting on the client, not marked as a rejection, and your team can send it again.
PublishingSome publish, GoMimic hands over
Approval tools: Planable and Kontentino publish to social networks. Filestage and Ziflow don’t.
GoMimic: GoMimic never posts. The approved version goes to your team’s tools, and your team publishes it.
ScopeApproval, or one job
Approval tools: Each is built around the review.
GoMimic: GoMimic covers one job: client content, created in the client's voice, approved by the client, and delivered by your team.

Spring regatta recapWhen an Approval Tool Is the Better Choice
An approval tool is built for these and GoMimic isn’t.
- Scheduling and publishing from the same tool, with Planable or Kontentino
- Proofing video, design, and print files, with Filestage or Ziflow
- Content your team already writes and only needs signed off
What You Pay For Is What They Think the Job Is
Look at what a tool charges by, and you will see the job it was built around.
- A seat means the job is a person's access.
- A client workspace means the job is a client's project.
- A flat agency price means the job is the whole roster.
Where GoMimic Is Not a Fit
- GoMimic never publishes. You can give each post a go-live date, but your team posts it. If you want one tool that posts for you, this isn’t it.
- GoMimic works with written content. It doesn’t proof video, design, or print files.
- GoMimic is built around a client list. One in-house brand gets less from it.
- GoMimic holds up to 30 clients and 10 people on Agency. Past 30 clients, we talk about a Custom plan.

Questions
What is the best client approval software for agencies?+
It depends on what needs signing off. Planable and Kontentino fit social posts you also want published. Filestage and Ziflow fit video, design, and documents. GoMimic fits written client content you also want created in each client’s voice.
Do clients need an account to approve?+
Not in GoMimic: a client approves by link, with no account, on a phone or a laptop. They type their name, and you can require an emailed code. Each tool has its own rule, so check its current page before you choose.
What happens if a client never answers?+
Nothing is approved. When the link closes, the post is still waiting on the client, not marked as a rejection, and your team can send it again.
Can I show who approved what?+
Yes. Approved text is locked, and each decision stays on a record that is added to and never rewritten, so you can show who approved what, and when.
Does GoMimic publish the approved post?+
No. GoMimic never posts. The approved version goes to your team by copy, to a folder for that client in your Google Drive, to Slack or Notion, as a draft in Buffer, Kit, or Mailchimp, or by webhook, and your team publishes it.
How is GoMimic priced?+
A flat price per agency, not per client, with up to 15 clients on Pro and 30 on Agency. Pro includes up to 3 people and one approver per client; Agency up to 10 people, more approvers, and reminders. Current prices are on the pricing page.
