seeking (or building) an ai browser extension with inline form suggestions + multi-field support

hey all — i'm looking for an existing tool (or folks interested in building one) that can intelligently assist with filling out web forms. not just basic autofill, but something smarter — context-aware, user-aware, and unobtrusive.

here’s what i’m envisioning:

a browser extension that stays dormant until triggered (via right-click or keybind)

when activated, it should:

analyze the current form — field labels, structure, surrounding content

offer inline suggestions (ideally like copilot/intellisense) or autofill prompts i can tab through or accept

optionally suggest values for multiple fields at once when context allows

learn from my past entries, securely and privately (preferably local-first)

essential features:

gpt-4o or local llm integration for generating smart, field-appropriate responses

inline ui for previews/suggestions (not just “fill all”)

context menu or keyboard-triggered activation

encrypted local memory of my entries and preferences

multi-profile support (personal / work / educator etc.)

open source or built for extensibility

i’ve tried tools like harpa ai, compose ai, and magical — they get partway there, but none offer true inline, multi-field aware suggestions with user-defined control and memory.

if this exists, i want to use it.
if it doesn’t, i’m open to building it with others who care about privacy, presence, and usefulness over noise.

thanks.
