Sources that aren't Aid Another or don't play nice:

	Insightful Advice; actually is Aid Another, but cannot be modified
	Cooperative Crafting; allows similar effect, but +2 circumstance bonus
	Order of the Staff (cavalier): +2 competence bonus on next concentration, dispel, CL check, scaling; is AA, but isn't
	Vigilante Bellflower Harvester archetype, crop vigilance: sets skill, attack, or AC bonus at +3, scaling, for "crop" allies (standard action to set allies as crop)
	Divine Strategist archetype Caster Support (Su): Scaling CL check and concentration, but Circumstance bonus; starts at +2
	Asavir PC, Camaraderie (Ex): In combat, scaling increase in Aid Another; does not stack with other increases.

Cool tricks:
	Effortless Aid (Ex) investigator feature; AA as move action, or spend Inspiration to AA as swift action
	In Harm's Way procs on Aid Another; immediate action
	Covering Fire (Ranged Tactics Toolbox); Aid Another at distance to modify AC only
	Got Your Back feat; Deny flanking, flat-footed. RAW, only works with +2 to AC effects, but RAI is unclear. Combine with Covering Fire for hilarity.
	Harrying Partner feat; extends benefit of Aid Another to AC and attack.
	Open Up feat; if improving attack roll, enemy's physical shield irrelevant to AC; calls out Harrying.
	Team Up feat; super limited, but move action for *any* Aid Another
	Harder They Fall feat; allows bull rush and trip for very large opponents
	Born Under The Cradle (combat trait): +2 trait bonus to attack rolls to *perform* Aid Another
	Mentored (social trait): +1 trait bonus to skill check to Aid Another with a skill. PFS legal, other bennies
	Supportive (social trait): +1 trait bonus to skill checks to Aid Another; no other bennies; vaguely more permissive language
	Effortless Aid (race trait, Garundi human): very specific, but fairly powerful take 10 to Aid Another
	Jungle Opportunist (catfolk race trait): +1 trait bonus to damage under specific circumstances on Aid Another
	Brutal Grappler (combat, teamwork): may attempt to damage foe *as well* as assisting grapple
	Guarding Ladder, Equipment Trick Ladder (combat): use ladder to improve AC at 10' while using it as a shield (?!)
	Halfling Opportunist, Excellent Aid (Ex): Increases bonuses *others* give to *Opportunist* by 1, scaling
	Acrobatic Assist, rogue talent (Ex): AOO to AA an acrobatics check; also grants +1 dodge bonus vs. AOOs.
	Slayer, Studied Ally talent (Ex): move action to get +1 to Aid Another actions.
	Battle Herald, Teamwork inspiring command (Ex): Allies gain bonus to attempts to AA and to the resulting AA bonus
	Pathfinder Field Agent, Deft Defender (Ex): When successfully using AA to increase ally's AC, gains own +1 dodge

Edge cases:
	Accursed bloodline arcana, and its lesser cousin Coven hex. Explicitly "Aid Another" which modifies CL. I say shenanigans. Relatedly, feat Coven Caster. "Special aid another action" changes CL, but doesn't require the hex or arcana.
	Psychic Hag-called discipline gets similar effect, adds psychics to recipients, but cannot join a coven.
	Arclord of Nex, Third Eye (Su): raises CL and grants circumstance concentration bonus, but set and RAI dubious as AA
	Ensemble (teamwork) is oddly restrictive and difficult to parse; it doesn't seem to grant any especially powerful benefits, and may be intended primarily to empower Bardic Performance.
	Ankou's Shadow, slayer archetype, Shadow Double (Sp): doubles use BAB + int to roll to AA, Swift action for player
	Tactician fighter, cooperative combatant (Ex): Specifies +2 bonus, but RAW may not reflect RAI

Items and Equipment
	Benevolent armor: Adds armor enhancement bonus to AA's AC bonus
	Benevolent weapon: Melee only, adds weapon enhancement bonus to AA's attack bonus
	Gloves of Arcane Striking: adds wearer's Arcane Strike damage bonus to AC or attack roll
	Ring of Tactical Precision: Increases bonus from AA by +1, other benefits
	Banner, Bastion: allies gain +4 sacred bonus on rolls to AA (no increase in AA bonus itself)

Spells
	Spiritual Squire, Allied Cloak: can Aid Another, though probably difficult to modify
	Rune of Rule (kindness): Allows an ally to AA for +5
	Ally Across Time: Allows you to AA yourself, though only statistics and teamwork feats apply

Companions
	Valet familiar can Aid Another on the move; bonus not set. Give that monkey a ring. Also can use the aid another action as a full-round action to grant up to three adjacent creatures bonuses from this action. Each bonus can apply to the same action or check or to different actions or checks.
	Protector familiar can AA even without threatening a foe, though needs line of effect to both and sharing square
	Mascot familiar, uses the aid another action to improve a team member’s attack roll or AC, that team member also gains a +1 luck bonus to AC for 1 round. No provisions to allow to threaten; consider Evolved Familiar for reach
	School familiar, Necromancy, can Aid Another to help an ally deal full damage to incorporeal; no provisions for threatening, so consider means of achieving reach
	God Caller eidelon: Eidelon's Aid Another can allow two rolls and choice of result in Diplomacy and Intimidate, and may change two steps 1/day


Monsters
	Wysp, elemental, Resonance and Servitor special abilities. +4 AA to kineticists sharing its element.
