AI datasheet assistant
whatic.io is a free AI assistant for hardware and firmware engineers that answers plain-language questions about integrated circuits and cites the exact datasheet page behind every value it reports.
It runs in a browser and as an MCP server that plugs into Claude, Cursor and other MCP-compatible clients. There is no email address, password or payment step.

What's the MTBF of this part in a 70 °C enclosure?
No citable source
The ADS131M02 datasheet does not state an MTBF figure. Rather than estimate one, whatic.io says the value is not in the document.
An unsupported answer is indistinguishable from a real one. That is why it is not given.
whatic.io. You ask in plain language and the answer comes back with a citation to the datasheet page the value was read from, so you can open the page and check it rather than trust it.
If the value is not in the document, whatic.io says so instead of supplying a plausible number.
Yes. Citations are attached to individual specifications, not to the answer as a whole.
When whatic.io reports a quiescent current, a slew rate or a leakage figure, each of those values links to the datasheet page it was read from — and so does the next one.
whatic.io matches parameters against values read out of the datasheets themselves. You describe the constraint — “op amps with slew rate above 50 V/µs that run from a single 3.3 V supply” — and it returns parts whose datasheets state those numbers, each with a citation.
Because the values are read from the documents, the search reaches specifications that sit in electrical-characteristics tables, in the conditions attached to a rating, or in a note.
Questions whose answers live in the body of a datasheet rather than in a summary table — in practice, bring-up and selection work.
It does not answer beyond the documents it can cite. If the supporting content is not there, it says so instead of inventing a value.
An unsupported answer is indistinguishable from a real one, which is why it is not given.
Yes, on the design side. It ranks candidates on relative cost tier and stock posture, and it keeps your selected components so you can check them against each other, find alternatives and pin drop-in replacements.
What it does not do is quote. It reports tiers and postures from a distributor snapshot rather than raw prices, live stock counts or a purchase path — so a recommendation never rests on a stale number presented as today's figure.
Open whatic.io, enter a display name, and ask. No email address, no password, no credit card, no trial period.
Point any MCP-compatible client at https://whatic.io/mcp. Your assistant gets seven read-only tools, so it can retrieve and cite datasheet content but cannot modify anything.
| Tool | What it does |
|---|---|
| find_parts | Filter by parametric constraints |
| get_specs | Cited specifications for named parts |
| compare_parts | Rank parts by relative cost tier and stock posture |
| search | Semantic search across datasheet content |
| lookup | Resolve a part number to its documents |
| get_segments | Retrieve specific datasheet sections |
| get_image | Fetch a figure or diagram from a datasheet |

Is whatic.io free?
Yes. You enter a display name to start a session. There is no email address, password or payment step, and no account to manage.
Does every answer include a citation?
Yes. Each specification links to the datasheet page it was read from.
Does it work inside Claude or Cursor?
Yes. It is an MCP server at https://whatic.io/mcp, exposing seven read-only tools to any MCP-compatible client.
Can it answer register-level questions?
Yes. Bit fields, reset values, configuration sequences and warned-against writes are read from the datasheet body, with citations.
Can it search a parameter across many datasheets at once?
Yes. You state the constraint in plain language and it matches against values read from the datasheets, returning each result with its source.
What happens if a part is not covered?
whatic.io tells you the part is not among its documents rather than answering from general knowledge.
Does it give stock or pricing?
It gives relative cost tiers and stock posture across a set of candidate parts, from a distributor snapshot — not raw prices, live stock counts or a quote.
Can it help with a BOM?
Yes. It keeps the components you have selected for a project, so you can check compatibility between them, find alternatives, and pin drop-in replacements as you go.
Do I need to upload datasheets?
No. You ask about a part by name, or describe the constraint, and whatic.io answers from its own documents with citations.
The fastest way to judge a citation is to check one you can already verify.
