ai that cannot act without you.

cosigno does the busywork in the apps you already use. it always asks before it sends, changes, or spends anything.

free plan. no card. about two minutes to set up.

cosigno wants toneeds your signature

reply to 3 leads who asked about pricing

gmail, 3 recipients, drafted not sent

to: dana@northwind.co, sam@lumen.io, r.patel@arcadia.dev
subject: re: pricing for a 12-seat team
body: happy to walk you through it. here are the three plans.

in plain words

it does the work. you keep the say.

tell it what you want done

in a sentence, the way you would ask a person. “clear my inbox and answer the leads.”

it works inside your apps

gmail, slack, drive, stripe, your own tools. it reads, sorts, drafts and prepares.

it asks before it does anything real

sending, changing, spending. you see exactly what it wants to do, and you say yes or no.

why we built it

the useful part of an ai assistant and the frightening part are the same part: it can act. most products answer that by making the ai weaker. we answer it by making the moment of action visible. one card, the exact thing it wants to do, and your yes or no.

nothing sends, changes or spends without you. that is not a setting you switch on. it is the whole product.

ready? try it free or watch it run, no account needed for the second one.

without cosigno

give ai your accounts and it will use them.

it can email your customers, spend your money and change your live site before you notice.

with cosigno

everything stops right here.

the work is still there. it simply stopped, and it will not move again until you answer.

cosigno wants toneeds your signature

send 412 emails to all-customers

gmail, 412 recipients, cannot be unsent

to: all-customers (412)
subject: an important update to your account

412 people are waiting on your answer.

everything continued, with your name on it.

how cosigno works

01

it shows you the plan first

your goal becomes a list of steps. each step names the app it will use and says whether it can go ahead on its own or has to ask you.

plan: answer everyone waiting since the 1st

  • 1read the last 14 days of repliesruns on its own
  • 2group them by what they asked forruns on its own
  • 3draft one answer per groupruns on its own
  • 4send the four answersneeds your signature
  • 5refund the two duplicate chargeslocked, needs typed confirmation
  • 6write the summary to driveneeds your signature
02

you approve what matters

at the step that would change something real, it stops. it will not skip it, guess at it, or carry on until you have answered.

cosigno wants tolocked, needs typed confirmation

refund the two duplicate charges, $96.00

stripe, 2 customers, cannot be undone

charge ch_3PmQ1a   $48.00   dana@northwind.co
charge ch_3PmQ7f   $48.00   sam@lumen.io
reason: duplicate charge on the same invoice
REFUNDtyped, not clicked
03

it finishes and shows its work

approved steps run, get checked, and close themselves out. you do not have to come back later to see whether the last one landed.

four steps, two of them yours. it closed itself out and left the receipts behind.

your apps

connect everything. hand over nothing.

each app asks for the least access it needs. you decide what it may do on its own and what it must ask about. cosigno cannot change those rules.

gmail
slack
github
notion
calendar
outlook
drive
your own api
runs on its own

search, summarise, draft

needs your signature

send, post, update, spend

locked, needs typed confirmation

refund, delete, pay

refunds, deletions and payments are always locked. cosigno cannot unlock them, and it cannot give itself more access.

approvals

the approval is the product.

other tools tell you what the ai already did. cosigno shows you the card first, and waits. same card for a small thing as for a costly one.

three actions are waiting.

cosigno wants tolocked, needs typed confirmation

refund $96.00 to two customers

stripe, 2 charges, cannot be undone

2 charges, $96.00 total, both on invoice 2214
every line is shown before you answer.
charge ch_3PmQ1a   $48.00   dana@northwind.co
charge ch_3PmQ7f   $48.00   sam@lumen.io
reason: duplicate charge on invoice 2214

read it, change it, or throw it away. the job waits either way.

this is a locked action. type its name to approve.

signed & executed

not approved. nothing has run. no receipt yet.

ready to hand something over?

give it one job and watch where it stops. you can do that in about two minutes, and it costs nothing.

25 ai operations / month, 1 connected app, no card

the record

you can always ask what it is doing.

everything it asked, everything you answered and everything it ran lands in one list, with the exact details it used. search it, filter it, export it.

emergency stop

one button stops every job at once and clears whatever was waiting. anything you already approved keeps its receipt. nothing else survives.

stop everything

who this is for

built for teams already running ai at work.

for teams whose ai already works, and who now have to answer for what it did.

3

levels of permission. every action lands in one of them first.

0

changes made without your say-so. reading, summarising and drafting go ahead on their own. nothing else does.

100%

of what happens leaves a receipt, including the things you turned down.

1

button that stops every job at once and clears what was waiting.

there are no customer quotes here yet. cosigno is onboarding its first teams, and a quote from someone who has not used it would be worth nothing to you.

be one of the first teams

pricing

one signature. three sizes.

one operation is one step of thinking, or one action taken. every plan asks you the same way. being asked is never an upgrade.
