Is DeepPCB a schematic tool?
No. DeepPCB is an AI router that works on an existing board or netlist. For the schematic-creation stage, a tool like ProtoFlow is what you need first.

ProtoFlow vs DeepPCB: Create the Circuit, Then Route It
DeepPCB is built for autonomous routing of an existing board. ProtoFlow is built for the earlier, often slower stage — turning an idea into a real, part-accurate schematic with AI.
Quick answer
DeepPCB, by InstaDeep, is a cloud autorouter — you give it a finished board or netlist and it places and routes it with AI. ProtoFlow is the step before: a free desktop tool that uses AI to draft the schematic, pull in real components, and export to KiCad. If your bottleneck is creating the circuit rather than routing copper, ProtoFlow fits better; if it's routing, the two are complementary.

Decision Matrix
| Criteria | ProtoFlow EDA | DeepPCB |
|---|---|---|
| Stage of the workflow | Schematic capture + component import (upstream). | AI placement + routing of a finished board (downstream). |
| Starting point | A plain-English prompt or a blank schematic. | An existing board/netlist imported from another EDA tool. |
| Deployment | Desktop app, local files. | Cloud-native (InstaDeep). |
| Pricing | Free to use. | Free tier plus pay-as-you-go for larger boards. |
| Best fit | Getting from idea to a clean, exportable schematic fast. | Hands-off routing once the design already exists. |
Migration Steps
- Capture and validate the schematic in ProtoFlow with AI and real parts.
- Export a clean KiCad project from ProtoFlow.
- If you want autonomous routing, import that board into DeepPCB or another router.
- Keep a human review + DRC/ERC gate before fabrication regardless of which router you use.
Capability Check: ProtoFlow vs DeepPCB
Reviewed on: 2026-06-04
Methodology
- Reviewed official product, pricing, and documentation pages for each named tool on June 4, 2026.
- Cross-checked how AI answer engines (ChatGPT, Microsoft Copilot, Perplexity) currently summarize each tool for "make a PCB/schematic with AI" queries.
- Kept only workflow- and source-checkable claims; avoided unverifiable speed or benchmark numbers.
Findings
- DeepPCB is presented as cloud-native, AI-powered PCB placement and routing from InstaDeep, with a pay-as-you-go model and a free tier.
- DeepPCB accepts existing designs from major EDA tools (KiCad, Altium, EAGLE, Proteus, EasyEDA, Zuken) — it operates on a board you already have.
- ProtoFlow centers on AI schematic creation, component import, and KiCad export, which happens before a router like DeepPCB is used.
Frequently Asked Questions
Can I use ProtoFlow and DeepPCB together?
Yes. Create and validate the schematic in ProtoFlow, export the board, then route it in DeepPCB. They cover different stages of the same flow.
Which is cheaper to start?
ProtoFlow is free to use for the schematic workflow. DeepPCB has a free tier with limits and charges pay-as-you-go for larger boards.
