Pricing
Three flat plans. Designs, not credits.
Ohmeris is not open yet: join the waitlist and we will email you when it opens. When it does, each plan starts with a 7-day trial, no card needed. Each plan is a fixed monthly price with a set number of AI designs, and the AI never charges you for its own retries.
Basic
$9 / month
40 AI designs a month (up to 10 a day)
- Schematic editor with the real-part picker
- Analog SPICE simulation: transient, AC (Bode), DC sweep, operating point
- PCB layout, 2 or 4 layers, with DRC
- Exports: KiCad PCB, Gerber, ODB++, pick-and-place, open JSON
- Private projects
ProMost popular
$19 / month
100 AI designs a month (up to 25 a day)

Premier
$49 / month
280 AI designs a month (up to 60 a day)
- Everything in Pro
- Real serial port: connect the bench terminal to a real Arduino or USB-serial adapter (Chrome or Edge on desktop)
- The highest AI allowance

Need more AI designs? Coming soon: top-up packs, 50 designs for $9, on any plan. They never expire.
Questions
- What counts as an AI design?
- One message to Benchmate, the AI assistant, that drafts or changes a circuit is one design. If the AI repairs its own attempt before answering, that is still one design. A request that fails before the AI is called is not counted, and neither is one the AI service refuses before it starts answering. Once the AI has started answering it counts, even if the result is rejected. Things that do not use the AI (for example a Bode plot) cost nothing.
- Why a daily limit as well as a monthly one?
- The monthly number is your allowance. The daily limit only stops one day from using most of the month. Both reset at midnight UTC; the monthly allowance resets on the first of each month (UTC).
- What if I run out?
- Top-up packs are coming soon: 50 more AI designs for $9. Top-up designs never expire and are used only after your plan's monthly allowance. Until then, the daily and monthly limits reset as usual.
- What happens during and after the trial?
- The trial lasts 7 days and needs no card, so nothing is charged when it ends. It unlocks every feature, with AI at the Basic level (up to 10 designs a day, 40 in total). Exports start with a paid plan. After the trial your projects stay readable; pick a plan to keep editing.
- Can I take my designs elsewhere?
- Yes. Every plan exports KiCad PCB files, Gerber, ODB++, IPC-356, pick-and-place, SPICE netlists and an open JSON copy of each project.
- How do I cancel?
- From your account settings, in one click. No email or call needed.
- Are the PCB exports ready to send to a fab?
- The exports are checked by independent software, but we have not yet built and tested a board from them ourselves, so review them in your fab's viewer before ordering.
