Less uncertainty at each step

01 / START

The next useful action

A home screen that makes progress obvious.

Measure: next-action completion
02 / EXPLAIN

Your year, in your words

Voice that produces facts you can review.

Measure: time to confirmed facts
03 / CHECK

Evidence with a clear owner

An assistant resolves gaps with your input.

Measure: unresolved items at review
04 / FOLLOW THROUGH

A notice with a next step

Proposed outcomes, not measured results. Taxfix already offers AI assistance and document handling. The opportunity is coordination around reviewed work.

PRODUCT THESIS02 / 07
taxfix ✳01 / PROACTIVE HOME

The opportunity

One clear next step

People need to know what still requires them. A prioritized action helps them resume with confidence.

The experience

One task leads the screen. Preparation and evidence helpers show what is ready and what needs review.

Why now / implementation

Connect existing document and assistant signals to a shared task state. Begin with a rules-based priority queue.

Primary metric: next-action completion.
Guardrail: corrections after final review.

REVIEWED PROGRESS03 / 07
taxfix ✳02 / VOICE INTAKE

The opportunity

A conversation
that does the work

A job change or move rarely arrives as a tidy form response. Voice lets people explain it naturally.

The experience

Tell the story, inspect proposed facts, edit them, then confirm. Text remains available throughout.

Why now / implementation

Stream speech into typed fields with transcript evidence. Ask only for missing details before user approval.

Primary metric: time to confirmed facts.
Guardrail: correction rate and voice abandonment.

VOICE WITH A RESULT04 / 07
taxfix ✳03 / EVIDENCE REVIEW

The opportunity

A receipt needs
context, too

Recognizing an amount does not establish work use. That missing context should have a clear resolution path.

The experience

See the source, confirm a supported work-use estimate, and save the decision. Ask an expert when unsure.

Why now / implementation

Extend existing document recognition with field provenance, a gap queue, and reversible human decisions.

Primary metric: unresolved evidence at review.
Guardrail: expert rework and unsupported allocations.

HUMAN JUDGMENT WHERE IT MATTERS05 / 07
taxfix ✳04 / NOTICE FOLLOW-THROUGH

The opportunity

The return ends.
The questions don’t.

A different result can leave people uncertain about what happened and what to do next.

The experience

Compare the notice with the submitted return. Review the source passages and prepare a useful expert brief.

Why now / implementation

Combine structured document comparison with evidence retrieval. Keep tax interpretation and response decisions with qualified experts.

Primary metric: discrepancy-to-resolution time.
Guardrail: false flags and missed response deadlines.
