01 / Who this is for
Brainis vs 15Five
You use 15Five today and want to know if Brainis replaces it, works next to it, or isn’t for you. The honest answer is below, including where 15Five wins.
15Five is about the relationship between a manager and their reports. Brainis helps run the company. They overlap less than a feature list suggests.
02The difference
15Five runs the performance conversation. Brainis helps run the company.
In Brainis, 15Five's job (check-ins, one-on-ones, reviews, engagement signals) belongs to the performance half of People AI. Brainis isn't mainly a performance product. It keeps a live picture of the company, decides the next move after mapping the options, turns it into missions, and has the finished work checked.
15Five is a performance and engagement tool. In Brainis, that job belongs to People AI, working with the rest of Brainis.
03When 15Five is enough
Stay on 15Five if this is you.
This isn't a setup. If one of these sounds like your company, 15Five is the better buy, and we'd rather you hear it here.
The rhythm between managers and reports is what you're fixing
Weekly check-ins, one-on-one agendas and light reviews are a specific practice, and 15Five is built around it with real care.
You want managers to use something simple
A narrow product that managers open every week beats a broad one they open every quarter.
Measuring engagement is the goal
If leaders want a regular read on how people feel, that's what this kind of tool is for.
04When you need Brainis
What Brainis adds, and the part that does it.
Each one names the part of Brainis doing the work (Company State, missions, Verify, what I do on my own) and links the page that proves it.
When performance signals should change what the company does
Company State holds goals, customers, money and promises in one live picture, so a people signal sits next to the rest of the evidence instead of in its own tool.
See Company State →When a decision has to become real work
A plan you approve becomes missions with owners, budgets and what done looks like.
See Missions →When AI work needs a separate check
Verify checks the work against what you asked for and can send it back. The AI that did it never checks it alone.

05Side by side
Grouped by what Brainis actually does.
Only things you can check. The 15Five column says what 15Five does, and never claims a weakness we haven't checked. Where 15Five is better, the row says so.
Understand
What I know about your company.
One live picture of the company: goals, customers, money, promises
15Five
Check-ins, objectives, review cycles and engagement signals for the people who use it.
Brainis
One live picture, where each fact shows where it came from, how fresh it is and how sure I am.

Decide
How the next move gets chosen.
Options mapped before a path is recommended
15Five
Not what a performance tool is for.
Brainis
I map the options first. Change a limit, and my recommendation changes with it.

Deliver
How the work actually gets done.
How an approved plan becomes work
15Five
Check-ins and review cycles run on the schedule you set.
Brainis
Each plan you approve becomes missions, with the steps in order, an owner, a budget, and what done looks like.

Where the AI does its work
15Five

Verify
What has to be true before it counts as done.
A separate check before work counts as done
15Five
Not what a performance tool is for.

Who checks the work
15Five
Not what a performance tool is for.
Brainis
Never the AI that did it. Risky work is checked by a different family of AI models.
See Verify →
Your own standards as checks
15Five
Not what a performance tool is for.
Brainis
Your own rules for done become Verify checks: written once, grouped into libraries, applied area by area.

What the result changes.
What happens to a decision after it is made
15Five
Trend reports on engagement and performance. Predictions aren't recorded or graded.

Whether the forecast was any good
15Five
Trend reports on engagement and performance. Predictions aren't recorded or graded.

07Pricing
What each of us charges for.
15Five is priced per seat, by module. Brainis prices differently: each plan sets a number of seats and how much I may do on my own, AI credits pay for the AI work, and you see each cost before I run it. These products don't replace each other, so the pricing page is context, not an argument.
Brainis is free to start. Paid plans start at $29 a month. See Pricing →
