No shared limit
Every AI tool and agency bills on its own meter. Nothing adds them up, and nothing stops the work when a company's budget is gone.
AI agents, AI agencies and single-purpose AI tools now write, send and post for your business. COSI gives that work what they leave out: one monthly spend ceiling, one set of approval rules, one record you can verify, and results you can see, per company. COSI's own agents do the work inside those limits.
Plans from $149/month · AI usage included · hard monthly ceiling, no overage
Every AI tool and agency bills on its own meter. Nothing adds them up, and nothing stops the work when a company's budget is gone.
Emails, posts and claims go out on each tool's defaults. A clinic, a lender or a nonprofit needs one set of rules it chose, and proof they were followed.
When a hospital, bank or grant officer asks who approved an email or a claim, an activity log anyone can edit is not an answer.
These sit above the work, whoever does it. Each is enforced by the platform, not by a setting someone can forget.
Your plan's included usage is a hard monthly ceiling, with daily caps per agent. Pausing all work takes one tap and a reason; only a person can resume.
Levels 0, 1 and 2 for each campaign, channel and recipe. Anything that leaves the company runs at the level you approved, and complaints or bounces pause it on their own.
Runs, approvals, refusals and spend are hash-linked in order. Anyone you show it to can check that nothing was edited after the fact.
Mark a company regulated or clinical and it stays at level 0 until you record a counsel review. Clinical companies also refuse captures and website briefs.
Leads, replies, meetings booked, posts published and cost per result for each company, counted from stored events. Anything not yet connected says so instead of showing a zero.
Two-key row-level security in the database: organization and company. An agent that reaches for another company's records gets nothing, and the attempt is recorded.
Clinics and health technology, lending, tax and financial services, and nonprofits that hold donor or client data. Counsel gates, aggregate-only results and a Trust Center are built in, not bolted on.
A holding company, a nonprofit and a startup under one person. Each company gets its own agents, memory, budget and results, and nothing crosses between them.
If you want someone to run your ads for you, hire an agency or an AI growth service. COSI is what keeps AI work, including theirs, inside limits you can see and prove.
Each company gets a general manager agent, a chief of staff across the portfolio, and the memory to work in your voice.
Ask by text, Slack or voice. The right company's agent answers with that company's context, and results come back as house-style Word and PDF.
Build a company brief from its website. Every statement is checked against a verbatim quote before it can enter memory, and you approve what stays.
Sequences and posts run under a written policy with send windows, daily caps and suppression lists. Bounces and complaints pause a campaign on their own.
Long-form writing where every reference is checked against PubMed and Crossref and graded by study design before it can be cited.
Continuous control checks across GitHub, Google Cloud and Workspace, access reviews, risk and vendor registers, and a Trust Center for procurement questionnaires.
Agents propose better wording for recurring tasks. You pick blind between old and new on real inputs, and a drop in quality reverts it automatically.
Autonomy is set per campaign, channel and recipe, never per platform. Regulated companies stay at level 0 until you record a counsel review.
Monthly ceiling and one-tap pause. Work stops at the ceiling your plan sets. Pausing requires a reason, and only a person can resume.
A ledger you can verify. Runs, approvals, refusals and spend are hash-linked in order, per organization.
Refusals are recorded. When an agent reaches for another company's data or a tool it was not granted, the platform blocks it and logs the attempt.
Agents prepare the work. A person approves and sends every message, post and change.
A rule-bound approver checks each item against the policy you signed. The first 15 to 25 go out under your review, with spot checks after.
Approved work runs on schedule inside send windows and caps. Complaints, bounces or removals pause it immediately.
Pay on Stripe's secure checkout. We set up your organization, your companies and your first agents within one business day.
Your plan sets the monthly ceiling. Choose per-agent daily caps and the autonomy level for each campaign or channel.
Ask from the Command Center, Slack or voice. Approvals wait in one queue, and every result lands in your Library.
Choose Healthcare, Financial services or Nonprofit when a company is added, or later from its page. A preset only ever raises safeguards.
The company is marked regulated, or clinical for healthcare. Outreach, posting and recipes stay at level 0 until you record a counsel review, and anything already running above that pauses.
Compliance monitoring is turned on for controls mapped to HIPAA, SOC 2 or ISO 27001, whichever fit. Mapped, not certified: COSI is not audited, and says so.
A Trust Center overview is drafted and left unpublished, and starter answers are offered for your security questionnaires. Nothing is published or added until you approve it.
Other kinds of AI products are strong at what they were built for. COSI is the one built around several companies, a fixed budget, rules you set and a record you can verify.

Categories describe typical products of each kind as of September 2026, not any one vendor. A category may include products that do more. COSI does not replace an independent auditor.
Every plan includes the ledger, spend controls, approvals and the Command Center. Your plan's included usage is your monthly ceiling: when it is reached, work waits for the next month or a bigger plan. Pay yearly and get two months free.
For a founder running one company with a small team.
For owners running two or three companies.
For portfolios that sell to hospitals, banks or funders.
For holding companies, accelerators and health systems.
Checkout, invoices and card details are handled by Stripe; COSI never sees your card. Change plan or update your card from the billing portal. Cancel with one button on the Billing page of your Command Center: no call, no email, no fee. Read the cancellation terms.
Portfolio at half price for twelve months ($245 a month), direct access to the founder, and a say in the roadmap. In return: a monthly feedback call and permission to publish a case study. Accepted partners receive a code to use at Portfolio checkout.
Every agent has a company, a set of granted tools, and daily caps. Every organization has a monthly ceiling and a pause switch. Anything that leaves the building, like an email or a post, runs at an autonomy level you chose, and every step is written to a hash-linked ledger you can verify.
No. You pay the plan price and nothing else. AI usage past your plan's allowance does not run up a bill: work stops at the ceiling, and the Command Center shows spend against it at all times.
Only if you move a campaign or channel to level 1 or 2 and approve its policy. New campaigns start at level 0. Personal social profiles always stay at level 0, and replies, comments and direct messages are always sent by a person.
Yes. Isolation is enforced by row-level security in the database with two keys, organization and company. An agent that asks for another company's records gets nothing, and the attempt is recorded as a refusal.
COSI routes each task class to a current frontier model from Anthropic, with OpenAI and Google used for transcription and images. Routing is managed for you and priced into the usage allowance.
For many small companies it covers the day-to-day work. Studio monitors 13 controls mapped to SOC 2, ISO 27001 and HIPAA, runs access reviews, keeps risk and vendor registers, and publishes a Trust Center. COSI is not certified and does not certify you; you still need an independent auditor for a formal report.
No. COSI is the control layer, not a marketing agency. Its agents research, draft, send outreach and publish posts inside the limits you set, and its Results page counts what came of it. If an outside service does your ads, COSI keeps your own AI work accountable alongside it.
Yes, any time, with one button on the Billing page. No call, no email and no fee. Monthly plans keep working until the end of the month you paid for. For yearly plans and your data, see the cancellation terms.
13 controls mapped to SOC 2, ISO 27001 and HIPAA, monitored continuously. COSI is not certified or audited, and we will say so to your procurement team.
Cancel from the Command Center in two clicks. No call, no email, no fee, and you keep access to the end of the period you paid for. Cancellation terms.
The ledger is hash-chained per organization, so what you show an auditor or a board can be checked end to end.
