A hardware engineering assistant that cites every number it gives you.

Most design problems have an answer — it's just buried on page 47 of a datasheet. Ask Whatic anything, at any step of your design, and it finds the answer across the source documents and hands it back cited, in seconds — so you never have to wonder if the model just made it up.

Not another EDA suite — nothing to migrate, nothing to learn. Keep your tools; bring your questions.

What's here

• Every decision is labeled. A verified pick is pinned to a specific page in a datasheet, with the document hash and section shown so you can open it. Engineering convention and calculated heuristics are labeled as such — neither is hidden.
• Math runs through a calculator, not the model. Duty cycles, inductor sizing, peak currents: the agent writes the formula and runs it through a tool, then reports the result. Every expression and its inputs stay visible above the answer.
• It remembers your project. Rails, constraints and the parts you've picked carry across questions, captured as you chat. Say "we picked the LM3886" and every later answer accounts for it.
• One session per project. Each session keeps its own datasheets, facts and chat history.

Questions people ask it

• Recommend a low-power pressure/humidity sensor for a battery-powered environmental sensor node.
• Compare the ADA4807 vs AD8065 for a photodiode preamp — noise vs bandwidth, which wins?
• What output capacitor should I pair with the TPS63810 at 3.3 V, 500 mA?
• Will MCP73831 charge a 2,500 mAh cell from USB-2.0 within spec?
